Conceptual electric vehicle for rural and urban commuting Sponsored Project Duration: 12 weeks / June - August 2013
Gruas Triple A Primary conceptual stage of electric vehicle for city commuting in Lima, Peru. This project was developed for Gruas Triple A, a Peruvian company specialized in crane services, mechanical assistance and special delivery services, as a first step towards improving transportation in the outskirts of the city, envisioning a more secure and efficient compact vehicle that fits within the cultural and technological reality of Lima. It’s based on mototaxis, a three wheeled vehicle also known as rickshaw in some parts of Europe and Asia, this vehicle can be found all around Latin America, but most commonly in the poorest areas of the continent.

RESEARCH
10%
I thought that it was important to do a background research on the problem of transportation, traffic and road safety and how these vehicles were affecting each of these points. It was evident that traffic, and all the other problems it brings, is one of the biggest issues in my country and these vehicles are big part of the informality that is making this problem increase and affect pedestrian, passenger and driver safety. I also felt important to do a technical research of the assembly line to learn how these vehicles were constructed, what mechanical elements they used and what was the origin of their components.
OF ALL TRAFFIC ACCIDENTS IN LIMA ARE CAUSED BY MOTOTAXIS
6
PR O BL E M S & N E E DS B A C KG R O UN D 37 of the 49 districts in Lima have authorized the circulation of mototaxis but only 48% of these vehicles in the streets have the required documentation. These vehicles are only meant to connect the outer areas of the city, where public transportation has not yet been properly implemented, with main avenues and transportation routes, but nowadays they even circulate the most transited and congested streets in the center of the city. Most of the districts where the circulation of these vehicles is authorized are emitting permissions without having technical regulations or making a proper study of what’s the maximum amount of units needed per district. This lack of regulation together with the recent entrance of cheaper chinese components to the country have given place to the creation of informal assembly lines where these vehicles have no technical regulations and which construction is often improvised.
were chinese companies that sold assembly kits, these kits included only the main mechanical components: motor and frame, front and back wheels, as well as headlights and backlights. I found that it was very common for the new driver to buy this kit and then take it to an informal asasembly workshop where each owner decides the dimensions of the vehicle and the materials used which are usually composed of a metalic tubes structure and a body of fiberglass with vynil plastic applications.
PROBLEMS FOUND •
The informal assembly industry is creating vehicles that are not prepared for circulation endangering the passenger safety and often incurring in fatal accidents.
•
Improvised vehicles do not offer the necessary performance.
•
Lack of regulation is causing these vehicles to grow in number and begin to congest main avenues creating disorder and threatening pedestrian safety.
It is also important to know that mototaxi rides take 4.8% of transportation in Lima and they are responsible for 10% of all the accidents.
A SS E M B LY I began researching the structure and components of existent mototaxis such as wheelbase and track dimensions, wheels, combustion engines, fork steering (offset and trail), spring and hydropneumatic suspension, chasis materials and stucture. Then I proceeded to study the actual fabrication origin of these vehicles to which I found two main streams of comercialization. The stream were chinese and national companies that sold already assembled mototaxis in specialized stores. The second stream

IDE A T IO N
Shape and proportion exploration, here I tried to sketch the general dimensions required ti fit 1 driver, 2 adults passengers and 1 child. I tried to follow geometric shapes with dynamic lines to accentuate the compact shape of the vehicle.
8
At this stage I wanted to keep the idea of lightness, that we find in the existent mototaxis, through simple lines and surfaces, without completely closing the vehicle, that’s why I chose not to put doors at this point in order to allow an easy access and maintain a minimal language. On the other hand I also wanted to make a safe and compact vehicle, and I knew I could achieve that through the use of structural and shock absorbing materials such as rotational molded plastic with polyethylene filling and a solid but minimal structure.
9
REFINEMENT A
I worked with SolidWorks, a parametric modeling software, to build the interior and exterior of the vehicle. I started with the basic proportions of the interior and then worked with real scale dimensions to further refine the anthropometrics. I went through various iterations on the exterior lines and surfaces in order to accentuate the feeling of speed, lightness and compactness. After going through the design with the client and with material and mechanical engineers at UNITRADE, a rotational molding plastic factory, I proceeded to refine the remaining aspects of the vehicle.

After the ideation phase I started working on the body based on the main ideas obtained. I began defining main dimensions and proportions to then work with a real scale drawing to verify the dimensions.

CARGO
The driver’s seat is composed of three main bodies with an inclination of 100° in relation with the ground.
I was inspired by jet ski steering and handlebars, and tried to keep a dynamic shape with the least components as possible.
The back of the vehicle has a cargo space with an approximate volume of 240l. The space below the trunk is where the engine is located, moving the engine back helps improving the stability.

The back of the vehicle is where most of the mechanical components are located, including the engine, suspension, and cargo space which allows to have more space in the interior of the vehicle.
At first the headlights proposal was inspired by motorcycles aesthetics by using more dynamic lines, later I changed this to a more minimal shape that merged better with the main body.
This kind of sunroof works as another light source for the interior and helps to emphasize the sense of connection with the outside environment.

The carrying space at the back of the vehicle can be accessed by a back door that opens with the help of two hydraulic pumps.

Sunbeam handmixer Redesign process of Sunbeam handmixer Academic project Duration: 4 weeks / May 2011
The main objective of this project was to choose an existing product and analyse every aspect of it’s design, such as usability, internal architecture, anthropometrics and materials in order to make a new proposal according to the aspects of the design that the student considered could be improved.
21
ANALYSIS
As a product to work on I chose a Sunbeam hand mixer. Sunbeam is a more accessible product division of Oster, I chose this brand because its simple design would allow me to find aspects that could be improved. In the first stage of the analysis process we started by disassembling the product in all its separate parts in order to figure out each parts specific function and material. Then we took every measurement necessary and translated those measurements into a CAD software to create a 3d assembly model of the product.

At this stage we analysed the structure and morphology of the product, going through every element of its design, such as number of plastic cases, number and location of screws, surface textures and curvatures, materials used and buttons locations. This also included analysing its inner architecture and understanding the connections between elements and each one’s main function.

The main buttons have a very reduced action surface that require the tip of the index and middle finger to travel a significant distance to fully push each button.
• • •

1
The grip zone can cause critical wrist deviations when used by the 5th percentile of users, this can be redesigned to include both 95th and 5th percentile. Buttons have a very small action surface and have to be pushed too hard in order to work properly, this forces the fingers to an unnatural position. Both cases are integrated and can’t be detached for cleansing or storage, they are made of white ABS plastic which can eventually suffer discoloration. Because of the low potency of the electric motor food can take more time to be processed making the task take longer.

Improve buttons accesibility. Improve grip for better hand adjustment. Allow better product cleansing
25
IDEATION I began working with clay and paper sketches to explore different ways of handling the product. I wanted to find a grip surface that would allow an improved fit of the natural curvature of the hand. I also wanted to achieve a more natural and easy way of pushing the main buttons as well as a way to increase safety when using the product, this led me to experiment with a lock button that would reduce the risk of injury if improper use by children.
26
REFINEMENT
After the sketching process ended I proceeded to adapt the previous architecture to the new proposal. I kept every component previously used in the first hand mixer and added two new buttons ( I and II ) on top of the product that work both as lock and speed selector, this buttons are used with the thumb and they just need to be pushed once, this avoids forcing the wrist and hand position into uncomfortable positions.
27
Once plugged the user can choose two speeds, these buttons also work as a safety lock.
After usage the lower body of the product can be detached for better cleansing and storage.
The main button has a larger action area that allows the use of multiple fingers
28
PROTOTYPING
First I made a wooden model at the workshop so I could verify the dimensions and how well the handle fitted in the surface of the hand, after making some adjustments and modifications in the 3d model, I made a 3d print of the final prototype and began assembling all the separate parts.

Running Prosthetic Designing a prosthetic leg for Pablo Huaripata Sponsored Project: Kraft Foods Peru Patria Films Duration: 5months / March-July 2012
This project was financed by Kraft Foods Peru and Patria Films and I worked in collaboration with Ricardo Geldres, industrial designer and former proffesor at Pontificia Universidad Catolica del Peru and Diego Leon, freelance industrial designer. The main objective of this project was to experiment with local materials to see if it was possible to design a low cost and efficient running prosthetic for marathon runner Pablo Huaripata. Pablo Huaripata is a marathon runner from Cajamarca, Peru. He was born with a lower limb reduction defect that affected his right leg from above the knee, however this didnâ&#x20AC;&#x2122;t limit Pablo from practicing different sports and becoming one of the most known disabled marathon runner in Peru.
32
33
RESEARCH
Together with therapists from Ortopedia Wong we started studying Pabloâ&#x20AC;&#x2122;s condition, we studied how he walked and what parts of the body he used for each movement. We discovered that Pablo grew up using a crutch below his right arm all the time, which affected his posture and coordination when walking with a prosthetic leg. We started a rehabilitation process for Pablo to learn how to walk properly while we continued to work on the design.
34
RESEARCH The constant use of the crutch had caused a slight deviation in his shoulders line, rising his right shoulder a few centimeters higher when he walked and also affecting his arms-legs coordination, in other words he had to learn how to walk in order to use the prosthetic properly. Physicians took care of making a custom socket for Pabloâ&#x20AC;&#x2122;s leg and then was provided with a prosthetic knee and leg to start the rehabilitation.
Taking Pabloâ&#x20AC;&#x2122;s measurements

Solidworks sketches First ideas of the running prosthetic.
IDEATION
We started exploring with different shapes and surface curvatures that we thought could add more resistance to the piece, like adding concave surfaces to make the prosthetic endure vertical forces. We used simple and dynamic lines to communicate lightness. Following the sketching stage we started translating some ideas into CAD software to refine measurements and proportions.

38
PROTOTYPING
We chose three models to prototype and test, they were different in size, thickness and curvature, our aim was to prototype as soon as possible using different materials and bonding agents in order to put this models through different tests and see how each one responded to vertical forces as well as to evaluate bouncing and absorption properties.
39
Wooden prototypes
MAT E RIAL S E X P LO R A T I O N For the prototypes we chose to work with three different woods, tornillo, caoba and bamboo. Both tornillo and caoba are species native to the amazon forest and possess good flexibility and resistance properties. We also wanted to try with a bamboo prototype because of its well known strength, flexibility and lightness.
Laminating process

First prototypes of the three different models. This were laminated without any added reinforcement.
40
A DHESI VES EXPER I MEN TA TI ON Besides experimenting with woods we wanted to use different bonding agents in order to test and see how they interacted with the material thickness and surface area of each prototype. For the first prototypes we used a polyvinyl acetate based glue commonly used for gluing wood in carpentry. Then we used an epoxy resin bonding agent that required a co-reactant component in order to curate, different amounts of each of these components made the curating process faster or slower and it also affected the bonding strength and flexibility. For these prototypes we essayed different mixtures varying the amount of each reactant which then were applied to three prototypes, each with different mixture amounts. Finally we also used fiberglass and polyester resin reinforcements to some of the prototypes.
41
S O CK E T C O NNE CTOR PR OTOTYPE For the connection component we worked with aluminum plates until we had the correct angle. After making the final modifications for the socket connector we used two welded aluminum plates with the correct angle.
Connector

42
TESTING Having Pablo in Lima during part of the prototyping allowed us to constantly modify each model, once we made the final modifications for a proper fit we began testing them. We flew to Cajamarca to find Pablo and we stayed for 3 days testing the final prototypes.
43
Testing with Pablo These are screen captures from a video we took in Cajamarca, when testing the prototypes.
R E S U LT S & F I N D I N G S During the three days with Pablo in Cajamarca we could test each prototype through walking and running exercises. The one with polyvinyl acetate bonding did not show to be strong enough and broke after some exercises. The one with fiber glass showed to have better bouncing properties but was too flexible and could not hold Pabloâ&#x20AC;&#x2122;s weight. Finally the bamboo prototype, laminated with epoxy resin, showed to have enough resistance but not as much flexibility and was a little heavier than the others. After approximately an hour of use the welded plates that worked as the connector broke and we couldnâ&#x20AC;&#x2122;t proceed with more testing.
44
REFINEMENT
After various attempts with wooden prototypes we failed to find a proper combination of material and reinforcements that could result in a light but resistant piece proper for an athletic environment. Nevertheless, the experimentation with wood, besides helping us to identify the forces involved in the activity and how they reacted and distributed along the piece, also helped us to better understand the mechanical properties of each type of wood, and how the use of different bonding agents, thickness and numbers of layers can enhance stiffness or add flexibility to a piece. With these insights we concluded that a carbon fiber prosthetic could offer both flexibility and resistance for the task given, so we proceeded to apply what we learned by adapting the final design for the new carbon fiber piece.
45
CARBON FIBER / ALUMINUM After making the necessary changes to the final design we started the development of the new running prosthetic with the help of an auto shop that specializes in the fabrication of carbon fiber auto parts. We also designed a new aluminum connector piece for the prosthetic socket based on the insights we gained from the testing stage.
46

Popeye’s Playground
Children Playground area for Popeye’s fast food restaurant Sponsored Project Duration: 4 weeks / March 2013
This project was a collaboration between Infinito, a branding consultancy firm and Mectamo, an architecture and design studio, where I worked as a product design consultor. The client was NG Restaurants a food subsidiary of Intercorp, the brief was to design a children playground for a new Popeye’s fast food restaurant. The playground had to reflect the Louisiana Kitchen and New Orleans concept behind Popeye’s.

INSPIRATION
The Popeyes brand rescues the features of the original Louisiana kitchen, bringing the regional heritage of the southern United States closer to diners worldwide. Part of the brief was to work with concepts and ideas that could reflect the New Orleans heritage of the restaurant. We took as inspiration the carnival celebrations of Mardi-Gras and in it we found interesting elements such as the music ,colors, costumes, street lights and facades that we thought were elements that could add the energy and vibration needed on a playground circuit, so we used this elements to start the ideation of a dynamic experience.

The project is based on a new Popeyeâ&#x20AC;&#x2122;s restaurant, being constructed at the time, located in 895 Jose Leguia Avenue, Pueblo Libre District. The space dedicated for the project has an area of 126.00MTS2, however it is important to note that, given the nature of the assignment, the space had to be replicable to new locations with different areas and proportions.

At this age the game is characterized by action and a sudden increase of moving activities, focusing on the development of organizational skills and psychomotor skills. Children start playing and experimenting with elements that challenge their abilities such as net walls, tunnels and other structures that enable and encourage different motor responses.

Within the first ideas we proposed a line of slides that could take advantage of the roof height of the main windows area, beneath them a ball pit with little islands and a canopy that flew across the room. In the center of the space a totem-like carousel with bouncing balls.

Developing ideas Refining some of the initial ideas in SolidWorks
After presenting the first ideas to the client and discarding some of them for budget reasons, we began working on new proposals based on the client feedback and requirements. Some of the main concepts we began working on were the ideas of creating a circuit through a topography language of bumps or little hills and complimenting them with a set of slides in order to keep an active flow inside the circle. Other important ideas we worked on were auditory and visual stimulation through music instruments, textures and fictional characters.
58
S L I DE S & B A L L P I T
One initial idea that was interesting was the use of slides as part of the playground circuit, these slides created a tunnel-like area beneath them that added more energy to the circuit, we thought to complement this using a sort of ball pit. But sadly in one of the meetings with the client this idea was discarded for budget and technical reasons.

Other idea in development was the use of changes in the topology of the ground to create sort of little hills of grass of different sizes and functions that could work together to create a circuit. The idea was to achieve different activities through these different hills and create a modular system that would allow them to be configured in different ways.
ACT I V I T I E S We wanted to cover a certain range of activities within the different modules used, in order to offer children the possibility to use and develop their psychomotor skills, activities like climbing jumping crawling and balancing were necessary inside the playground, so we proceeded to refine each module and function.

Part of Infinito’s work was to create the graphics and characters on the wall. We incorporated the characters to a sort of mobile totem that allowed the children to rotate each body part to play with the animal and human version of each character, as we can see in the picture.

We also wanted to add some elements that could work as instruments and would allow to children to have an auditory feedback depending on the shape and material. The idea of instruments is a group of aluminum bottles, tubes and strings of different sizes lengths and thickness.

Vel贸 handcycle
Handcycle designed for people with leg inmovibility Academic Project Duration: 8 weeks / October - November 2011
This was an academic project developed in 2011, the main objective was to enhance the life of people suffering with any kind of mobility limitation by designing a vehicle or product that could solve problems frequently encountered by these users. I decided to redesign the common race handcycle by changing the way the vehicle is propelled and changing the muscles used in this activity .

RESEARCH
In the research stage I began by analysing existing handcycles including its structure, dimensions and propulsion mechanisms, following by an analysis of muscles involved during the activity. I learned that the muscles involved were mainly forearm, arm and shoulders which are a short / small group of muscles, so I decided to find a way to combine small and large muscles to achieve better propulsion. Regarding the vehicle I discovered important mechanical and structural facts to be considered such as wheelbase, base elevation, fork angle and trail distance for proper steering.

IDEA T ION I felt that with an activity like rowing the user gets to use a larger group of muscles that allows for longer movements and more strength input. So in the first sketches I tried to ideate a way of fusing this kind of activity with riding a handcycle and achieve a new and better way of riding that would also allow the user to reach higher speeds.

MECH A N IS M & P R O B L E M S In the first version of the vehicle I used a coil adapted to the interior of a single speed cassette to achieve a retracting mechanism for the rowing movement. But because the coil had to be fixed to the axle of the wheel hub the mechanism also activated when moving backwards, which did not allow to go backwards without the mechanism pushing you forward again. I also discovered that the radius of the cassette that I was using was to small and that implied considerable strength input to break the moment of inertia.

Prototyping

REF IN E M EN T
After prototyping the main structure and mechanism I found some aspects to be improved and simplified. In the second iteration of the vehicle I modified the mechanism to a cassette with a larger diameter that worked with a chain fixed to a spring to achieve the retraction movement, I also changed the front of the handcycle to fit the new proposal.
V E LO 02
IMP ROV E D M E C H A N I S M By changing the diameter of the cassette and using a chain connected to the frame by a spring it was easier to break the inertia and gain speed faster. This time the chain could move the way it is intended which solved the previous problem of activating the coil when going backwards. I achieved to have a continuous movement without the use of a complex mechanism but there were still problems with the steering that I didnâ&#x20AC;&#x2122;t have time to work on.

go.case Iphone 4 case
Personal Project Duration: 2 weeks / February 2012
Concept case for iphone 4. The project was part of an exercise to design a case that would allow you to place your phone somewhere reachable having it near whenever you need it. The idea was to see how a phone could be used as a sort of carabiner breaking the idea of fragility often associated with smartphones.
79
C O NCE P T
The idea was to design a protective case that could be attached to a carabiner in order to allow your phone to be hanged anywhere, sort of breaking the habit of having it on your pockets all the time and forgetting how fragile smartphones are. The case would be compatible with a small hook allowing to to use it both ways and experiment with the system.
80
ID EAT ING In the first sketches I did I began searching for a way of plugging the carabiner easily to the case without the case having to be bulky or too thick. Between the first ideas (A & B) I began refining proposal B to see if the idea would work.
81
Refining idea
Working with Autodesk Inventor on dimensions and proportions.
RE F IN E M E N T
In the refinement stage I started by creating a 3d model of the iphone, with help of a caliper I took every measurement needed in order to create a realistic model that would allow me to start defining the case dimensions. I used Autocad Inventor for both the iphone and case models and components, this software allowed me to work with very precise measurements and simulate how the hook would fit on the case.
82
3D Assembly

DESIGN 1
2 The case is composed of three parts: the main case (1) made from one piece of plastic, the clip (2) that attaches to the case both ways, from the bottom and from the top, and the carabiner (3) that is attached to the clip by a strap. The shape of the clip follows the case form in order to get a tight lock.

PROTOTYPING
After making some modifications on the 3D model I made a 3D print of the components to see and analyse the dimensions and proportions of the design. In this stage having a plastic prototype allowed me to test the flexibility and feel the weight of the product and experiment with the prototype to find details that need to be improved
86 A
PR OTOTY P E The 3d printed prototype of the case proved to be really close to a perfect fit, I could see that while it fitted it could be improved in order to increase protection. Regarding the carabiner and clip, the prototype showed to work as initially thought and it was useful in order to refine details for better attachment and fit. This was an interesting exercise that allowed me to quickly prototype an initial idea in order to test its viability and have immediate feedback on its usability.

Belt sander station
Internship Duration: 3 months / January-March 2012 Arenart
This project started as a graduation project financed by Arenart and then it was developed as part of a 5 months internship. Arenart is a company that specialises in the design and fabrication of trophies as well as promotional merchandise. The objective of the project was to redesign the existing crystal sanding stations in the factory by analysing every aspect and component of its design with the aim of finding problems that could be resolved by developing a new proposal.
89
RESEARCH
I started by analysing the existing working environment and then studying the belt sander used in the factory. I proceed to take every measurement necessary in order to translate them into a 3D modeling software. I used Autocad Inventor to create a model of the old belt sander in order to start working on the modifications. After having analysed both the working environment and the machine it was clear that necessary changes had to be made. I found that the main problem was the dust flying around the environment. Since the machine was not using water in the sanding process to capture the dust particles, and the components did not have any kind of cover or housing, the dust produced flew around the area affecting the workers and covering with dust every thing near them.

The first idea to come up from the ideation stage was to create a body that could house and protect the inner components and engine.
This body would also work as the structure for the cylinders, as a support for the working platform and give room to a water compartment located at the bottom of the belt sander. This was the first idea I started to work on and continue to refine along the design process.

P R OTOTYP I N G
At the factory we began the prototyping process, this first prototype allowed us to test the layout and stability of the new body. Making this prototype was crucial to identify weak points in the design. Since this was my first experience designing machinery with the help of engineers, despite the simplicity of the machine, this prototyping stage allowed me to constantly work and improve some aspects of the design in order to achieve the desired performance.
96
R ESU LTS & FI N DI N GS The first prototype showed that the attempt to use a unifying body as structure caused too much vibration when attached to the engine, I found that the components needed a more stable structure in order to keep the sanding belt aligned at all time and to give the engine the stability needed. Besides the performance issues, I also learned that it was necessary to have an easier access to some parts of the machine, such as the engine, transmission elements and the sanding belt itself.

After studying the feedback and insights from the first prototype I continued to work on the design, this time focusing on solving the issues of vibration, stability and usability. In this second iteration of the machine I experimented adding an independent structure that connected all moving parts with the engine in order to reduce vibration, I also added a separate cover to the transmission area to have a more direct acces to the pulleys and transmission belt.

MOD E L 2 In this version we added a new component (frame) that worked as a structure, serving as support for the inner components and engine, as well as for the housing of the transmission assembly such as the shaft, bearings and spacers.
FRAME
R E S ULTS & F I N DI N G S I found out that the new frame, while adding stability to the components and transmission, did not solved the vibration issue, because the frame was suspended by the casing and it did not reach the ground, causing the casing to vibrate. The new structure had to fix the engine and the components to the ground in order to gain more stability and lessen the vibration.

In the 3rd iteration we made the structure larger, this time also working as the fixation point for the engine and the moving platform. This also allowed us to make the water compartment larger and to use the frame as a support for the different casing components.

The second proposal of structure frame solved some problems but later in the prototyping stage it was evident that the structure had to extend in order to work as the core structure of the machine where all components are fixed.

With the addition of the new frame the assembly gained stability and performance, there was also more room for the water system which allowed to have more water and streched the refill cycle. This was the last iteration I was in charged of designing and supervising, next I proceeded to elaborate the new blue prints for the construction of the final prototype. 1. Water injection 2.
