INSIGHT

Seets2Meet was the space that more closely achieved the coworking principles that I founded in my desk research, so I chose it as my specific context.

Coworking spaces are very different from each other, I must focus on one to intervene.

Computer work (flex working)

THE PROCESS: The project had an open start: there was no predefined design goal (for example, fulfilling a given user need or solving a given user problem). We were free to identify a situation we liked and to define our personal design goal for it. During the project, we applied and develop research and design skills iteratively. We combined an explorative design and research approach where our insights help our design and vice versa.

Overview of the coworking spaces that I visited during my field research.

90% of the project was spent on design and research explorations in the so called Fuzzy front-end

These were the main stepping stones that were applied iteratibly throught the project: 1.

Choose a context

Analyse current interactions

Formulate a design goal

Develop an interaction vision

Generate starting points for innovative designs

Develop and test new concepts

Evaluate the final concept.

DESIGN & RESEARCH EXPLORATIONS

CONTEXT:

HOWTHE DOES IT WORK? PROJECT

LOTUS, FINAL DESIGN WHAT IS LOTUS? LOTUS is a connected device that stores the duration of the help received in form of light intensity. It enhances collaboration in working communities, by reducing the threshold of asking or offering help. It works as a reminder, for the user and for the rest of the community, of the amount of help given or received by the user, highlighting its value and encouraging them for further collaboration. Crosspollination of knowledge is a consequence of repeated punctual collaborations among coworkers, catalyzed by the use of

DESIGN PROCESS

DESIGN ITERATIONS INTERACTIVE PROTOTYPING & TESTING Building rough models enable to test and further develop interactions that people will experience through the design. The positive results of the test 03 validated my ‘‘Time-exchange concept’’ as a collaboration catalyst, so I could move on and start thinking about the best embodyment for my design 02 Lamp with cubes prototype

Through interactive prototyping, I explored the effects of my design ideas in the chosen context.

03 Cubes in plastic bags

01 Hourglass prototype

3D MODELING, ARDUINO PROGRAMMING & SOLDERING

The last part of the project consisted on developing an experiential prototype to evaluate its effect on the real context. For that purpose I needed to build two functional prototypes with Arduino that were able to communicate with each other. Each device has an Arduino Nano, a Bluetooth module (HC-05), a Neopixel Jewel, a battery holder and a button. Whenever a device is placed over the other, the lower one starts decreasing its intensity while the upper one starts increasing it (the light is transferred from bottom to top).

FINAL SHAPE Rail means a new approach to the adjustable table lamps design, never seen before. Extremely endurable, energetically efficient and comfortable to use, being able to illuminate a huge area.

Head and upper bars rotation through the horizontal axis

Head and counterweight slide

HEAD AND COUNTERWEIGHT SLIDE

Rail is a desk lamp, with a high grade of novelty in a few aspects. These are its main characteristics:

When the head is moved in one direction the counterweight moves in the opposite one, this way the lamp is always in balance.

UPPER ARMS ROTATION The arms with rails can rotate about an horizontal axis perpendicular to them. It can rotate almost the 360 degrees, the only impediment is the floor where the lamp is placed and base which blocks the longer part of the arms with rails.

•

It replaces the three conventional arms of the normal table lams for two, keeping all the positions required to a desk lamp. In total all the mechanism has five degrees of freedom.

•

It introduces the electric rails in the adjustable table lamps world. In this way the LED bulbs are fed by the electric current in any position that the spotlight could get, sliding trough the rails of the rotating arm.

•

It doesn’t have visible cables. The current flows from the base to the spotlight with out cables.

•

It doesn’t have springs, the balance is made by the mobile counterweight. Thanks to this it is more durable than normal adjustable lamps because it eliminates the possible failures caused by the spring fatigue, with the past of the years.

•

The LED bulbs can be easily replaced in case they get deteriorated or broken. They are conventional LED bulbs so they can be easily found in the market, so our adjustable lamp lasts indefinitely, getting disable just if it gets broken.

•

It is a big adjustable table lamp, it even can serve as a floor lamp.

BASE ROTATION 124.5 cm 37.5 cm

41 cm

The base is divided in two main parts, one of them is fixed to the vertical arms, and rotates with all the set about this vertical axis; and the other stays fixed in the floor, and all the lamp rotates about it.

The head can rotate 360 degrees through an axis perpendicular to the arms with rails. It can also change its orientations, rotating about an axis parallel to this arms; this movement will be explained later.

137 cm

HEAD ROTATION

It can illuminate a circular area of a two meters of diameter, with different light intensity depending on the hight where the spotlight is placed. It also can reach 1,40 meters high.

CONCEPTUAL DESIGN

SCOPE AND BASIC DIMENSIONS

The sliding area of the head is longer than the counterweight one, so it has to exist a relation between the two displacements. This relation is the same than the relation between the length of the two rails (head and counterweight), witch is 2,67.

To reach the objective, the lamp uses two pulleys; one responsible for moving the counterweight, and the other connected to the head with a transformation relation of 2,667. So the radius of the heads pulley its 2,667 times bigger than the counterweight one. Both pulley radius are 3D printed as a single part so they have the s a me a ng ular speed.

MECHANICAL SYSTEM

Illustration 1: Balance between moments about the rotation axis of the upper arms

BALANCE BETWEEN MOMENTS & LOADS PF

The mechanism of Rail is based in the proportional displacement of the head and the counterweight along the arm with rails in opposite directions.

Df = Distance between the head and the rotation center Dc = Distance between the counterweight and the rotation center Pf = Weight of the head Pc = Weight of the counterweight t = transformation relation = 2,667

In this way it will always be in balance for all its positions (equilibrium of moments) about two axis:

HEAD AND COUNTERWEIGHT DISPLACEMENT

When both pulleys rotate “n”laps, the smaller pulley will be moving the counterweight d1 x n x 2π units, and the bigger one will be moving the head 2,667 x d1 x n x 2π units.

Apart from that, there were to joints potentially complicated: The electric circuit finishes in two MR16 LED bulbs of 6W each. They work with DC and at 12V. Can by easily replaced if they end its life cycle.

Also it was a project requirement to use LED illumination, so I declined for the MR16 bulbs because it was the type of bulbs with the smallest bulb/cap assembly dimensions. Also they work with DC, which was another requirement if I wanted electric conduction through the external bars (no wires). The downside was the necessity of a driver to low down the voltage and turn the electric current to DC.

Base connection

Aluminum conductors

The main objective in the design of the electric system was the conduction of the electricity without visible wires in all the lamp, besides the need of an electric slide contact.

ELECTRIC COMPONENTS

The urethane covered ball bearings work as small wheels and ensure a super smooth and silent slide of head and counterweight.

SPECIAL CONNECTIONS & SLIDING SYSTEM

Between both washers it is hold the housing of the head witch can rotate 360º about the axis that crosses the washers

The head has two slider assemblies; one on each side. But only one of them has the gripping part that fix the head to the belt. The slider assemblies of the counterweight are almost identical but with less elements. There is no electrical connection so all the conductive parts are discarded. Also the griping part is eliminated, because the fixing to the counterweight belt is made differently (the belt is on the middle of the two rails, not in the edges) Lamps head Holder of the copper tape, made of HDPE Copper slider connector

HEAD CONNECTION In the upper arms there is installed a DC electric rail, witch consists on two copper tapes placed one on each arm. One works as the phase conductor and the other one as the neutral conductor.

The head has two conductive parts that slide along this copper tapes, getting electric power supply for all the possible positions of the head. It works in a similar way that a Scalextric. Besides, thanks to the belt (witch is griped to the head slider) it will pull along the counterweight that maintains the lamp in balance.

CENTRAL CONNECTION The electric connection is carried out thanks to the sliding rotative joint between the perforated copper washer (nº8) and the bimetallic plate (nº6). The perforated washer is connected by pressure to copper screw (nº10), that fits in its hole (so the washer rotates fixed to the upper arms). The screw is in contact as well to the copper tape (nº11) and threaded to the washer insulator (nº9).

This pieces slide through the head housing. They work as lateral covers, also allowing to rotate the spotlight moving them up and down with one hand (when one goes up, the other goes down). This lower covers cause the spotlight rotation. They are connected to the lateral covers, by a common axis and also to the bulbs housing by longitudinal slide. The vertical movement of the lateral covers cause the rotation of the read pieces, witch, because this connection to the bulbs housing, transmit to it its rotation, changing the orientation of the light.

The frontal covers just have an aesthetic function; they hide the interior part of the head, so the spotlight housing and the bulbs are not visible. They help to maintain the cubic shape witch is predominant in all the design, also allowing the rotation of the spotlight. They slide vertically through the housing of the head (1 degree of freedom) and against housing of the bulbs, with two degrees of freedom: rotation and slide.

ARM CONNECTIONS A REDESIGN EXAMPLE

HEAD CONNECTION The design process of the arms with slide has been long and it has been passing through many iterations. In first approaches the toothed wheel assembly was different and the joining methods were screws and nuts or threaded holes in the model pieces. This are some issues I solve with the definitive design:

CENTRAL CONNECTION

COUNTERWEIGHT CONNECTION

The central part is were the transformation relation takes place. The central wheel has two different radius and different number of teeth; the upper has 18 teeth, and the lower one 48, so the transform relation is 2,667.

The counterweight connection piece has to have in addition a static extra load to compensate the bigger weight of the arms in the head area.

This means that the head belt is going to translate 2,667 times more than the counterweight one.

ABOUT THE PULLEYS

•

It was difficult to assembly the lamp

•

There were many more pieces .

•

1 3D printed ABS toothed wheel

•

The joints were softer and reversible by the user (no needed)

•

1 steel (AISI 303) parallel pin DIN 7

•

The molded parts had a much more complicate and expensive design. And they needed to have threaded holes

•

2 plastic plain bearings Iglidur® GFM-0506-035

•

The rotation of the pulleys needed some kind of bearings to reduce the friction. The steel wheels were a bit big and to expensive for the required application.

This static counterweight is made of iron sheet shaped with oxicut.

Each toothed wheel assembly is made of four parts:

Old assembly drawing of the head connection. The number of pieces has been reduced from 19 to 14, and the threaded holes have been substituted by normal holes.

The bearings are inserted by pressure in holes of the two connecting parts. This is the smaller and cheaper solution for a toothed wheel assembly.

The original idea was to buy steel toothed metric wheels T2,5. This had two problems: They were to big, it was difficult to fit the wheels with bearings in the height of the arms with slide. And very expensive for the application requirements. To make them fit in the arms connection pieces it was necessary to mechanize the normalized wheels, so its cost triples (around 9€ each small wheel).

FIXED AND ROTATIVE BASE The base of the lamp its divided in two main parts, the rotative part (attached to the bars with the rail) and the fixed one, attached to the floor (because of the weight of the lamp and the high friction between floor and iron). The rotative parts can rotate when the user pull them, thanks to an aluminum axis that slides over a plastic bearing. The friction between the aluminum axis and the bearing is so low that the lamp is able to rotate on the vertical axis smoothly and quietly.

COUNTERWEIGHT

Its weight (thanks to an iron load inside) is 2,667 times the heads weight, so it balance the upper arms around its rotation axis. The counterweight design is pretty simple, its sliders are the same as

the ones of the head, but with out the conductive components and the grip to the belt. The fastening to the belt is placed in the center of the counterweight assembly as its shown in the picture of the right. The colored parts are fixed to the floor, while the rest can rotate through the vertical axis

AIM OF THE PROJECT Rowok is a conceptual design project that I did for Arnaiz and Partners, the Company I was working for during the fall semester of 2016. I worked on it along almost 4 months, but I was as well in charge of other projects, so I couldn’t spend all my working hours on it. In the project, I was following the instructions of a boss/ client that knew almost exactly the functions that he wanted the robot to have. Besides, I got the project in a middle phase, from another company.

PROJECT SUMMARY

ROWOK, KITCHEN ROBOT

My job was to improve the visual appearance of the robot, nail down its functionality and simulate the movement of the various mechanisms of the machine with Catia. Later, the project would be passed to a specialized product developing company, that would take the part design to further steps.

This was the appearance of the robot when I first got it from the client (left), and the final shape that I designed (right)

MOODBOARD

Inspired by the zeal for service, care and precision of the Japanese tea ceremony, Rowok easily develops a stronger and trustful bond with the kitchen staff

Clean shapes Offering gesture

Once the client accepted the proposed shape for Rowok, I began to work on Catia with the dimensions of the previous model. The final shape was obtained by working on the 3D software

SKETCHING CASE DESIGN

CONCEPTUAL DESIGN

Oriental inspiration.

Arm with spoons, for stiring the food

Nozzles of the sauces system. Three on each arm.

COMPONENTS & AESTHETICS Touch screen with the robots interface Extractor hood of active carbon filters (there is no need to connect it to an air vent) Cover of the fork/spoon arm and the cleaning arm, finished in black color to improve the appearance of the robot. It has a nice organic shape in contrast with the rest of the case. This shape facilitates the cleaning. Case .of the arms that hold the wok

Sink to evacuate the dirty watter and the soap after the cleaning process. It has two horizontal rails to fold the accessory table

Wok extraction system, it is possible to manually extract the wok and replace it for other one with different dimensions Wok Electric ceramic hob (with a curved shape) for heating up the wok. The electric current flows through the arms that hold the wok

Extra locker to keep for example some woks with different size

Locker for keeping the sauce deposits. Each of them is connected to one nozzle by a pipeline. So Rowok is able to choose between six different sauces

Folding accessory table to facilitate tipping over the food over a dish after cooked. When folded it frees the space of the sink, so the cleaning automatism can take place

3D MODEL EVOLUTION The three main changes I made from almost the beginning where the arm case, the division between upper and lower part and the head adapted to the extractor hood.

I decided to separate the robot in two parts; the upper part, with all the mechanism, and the lower part, with a sink and some drawers. In this way I could reach a much more interesting and aesthetic design. Now the robot starts being associate only with the upper part, so it looks more like a kitchen appliance rather than a whole block machine. The lower part is also essential, but its functions are much more ordinary, so it fuses with the furniture behind the worktop of the kitchen. The other big decision was to cover the arms of the wok with static cases. This arms are almost all the time moving during cooking; without static cover they could hit by accident any object that its around and get damaged. With the case they become easier to clean and also the cookers get an extra surface in the top of the arms cases.

CONCEPTUAL DESIGN

FINAL SHAPE

ARMS OF THE ROBOT The arms that hold the wok are in charge of two movements:

Idle position

Turning over food position

•

Shaking the wok

•

Tip over the wok forward or backwards

It has two motors, one for shaking, in the middle of the body of the robot, that connects with both arms. And one on each arm on the “elbow” that oversees tipping over the wok. Both motors never work together, once one of them is working the other one is not.

Cleaning position

COOKING MOVEMENT During the conceptual design phase, I also started to think on the trajectory we wanted the wok to have. I made an experiment at home, putting three led on different parts of the wok, and while moving it like if I was sauteing some food I took few pictures to visualize an approximate trajectory that the robot arms should reproduce. After that, I tried to reproduce this track in a mechanism designer software, (SAM) so I could define the dimensions of the arms needed.

Central motor in charge of the shaking movement of the wok arms.

Rotating connection between the arm and the body (one degree of freedom).

Behavior of the joint when turning over. The yellow axis threads though the fixed pink part, so it moves forward with the gray part. This connection works as rotative joint when the central motor is working (one degree of freedom) and as a slide and rotative connection when the elbow motor is activated (two degrees of freedom).

Anyway for my boss this wasn’t necessary and he establish the dimensions he wanted.

Led trajectory simulation Elbow motor in charge of the turning over movement of the wok arms. It rotates a threaded axis that at the same time moves forward the arms and provokes the movement of the gear system in the hand. Final wok trajectory during the cooking movement

Trying to approximate the real trajectory in SAM

When the elbow motor is activated this gear system translates the rotation of the axis connected to the motor to the rotation of the wok (one degree of freedom). When the central motor is working the gear system is blocked and it acts as a fixed joint (zero degrees of freedom).

HOW DOES IT WORK?

MECHANISM SIMULATION

Liang Cooking Technologies is a chinese industrial kitchen appliance company still under develop. Its founder, was a business associate of my boss in that moment. So I was in charge of designing a logo for the company and for the product, rowok.

LOGO DESIGN DESIGN ITERATIONS & FINAL RESULT

Liang Cooking Technologies logo develop. They all remind to the gear system, a soup bowl and the kitchen fire or ceramic hob. They also bring into memory precision and speed.

LIANG COOKING TECHNOLOGIES LOGO

ROWOK LOGO

The idea that my bosses had for the company logo was some simple design with powerful

A gear surrounded by a tongue

colors that reminds to a planetary gear mechanism, as well as to a the cooking. The

of fire is the logo I created for

planetary gear system was a very important part of the Rowok, and also a very common

the kitchen robot ROWOK. The

solution to increase the mechanical torque in a motor, so it was a good concept to define

colors of the gear remind to the

the image of a kitchen robot company.

food that is cooked in the wok.

LOGO DESIGN

Apart from the case design and the mechanism simulation I was also in charge of designing a logo for both product and company.

DESIGN FOR INNOVATION

Academic Bachelors project

CONCEPTUAL DESIGN 04 / 2015 - 06 / 2015

INNOVATION-DRIVEN DESIGN Summa is a prefabricated hanging bathroom that can be placed in the front of any house. It is perfect for little houses that, for any circumstances (increase of income, tenants, etc.) need a new toilet. With Summa we go a step forward from the common prefabricated rooms. The house does not need to be a new development, you can incorporate Summa to any house which has an empty, balcony free space on its front, of 2,75 x 2,75 m. Blocks of buildings are suitable as well and the installation is reversible. The gray waters from the sink are used to fill the toilet tank. Before arriving to the toilet, the water is filtered, disinfected and stored in a special tank (the blue tetrahedron placed at the front of the top left image). This tank is also fed by the cold water conduit, to prevent it from being empty. This system can save from 7.000 to 30.000 euros per home, yearly.

This individual project was made for Design Workshop II a course of third year of career, that I took during the spring semester of 2015. During this course we made three different projects, so each one took us around month an a half. The final goal was to present the project to the 6th Roca International Design context.

PRESELECTED PROJECT IN ROCA JUMPTHEGAP CONTEST 2014-2015

This contest was about developing an idea about Bathroom experience innovation My project SUMMA was preselected for the final with other 29 (15 students and 15 professionals) among the 3.724 participants of 112 countries in 637 projects.

In the images on the right it is shown the certificate and the document I presented to the contest.

PROJECT SUMMARY

AR & VR APP DEVELOPING ARQUITECTURAL MODELS VISUALIZATION I worked for few months in Arnaiz & Partners, an arhitectural studio were I developd VR & AR applications for building visualization in smartphones. All the work I did there was self tought, I learned to program with C#, the Unity environment and to develope AR and VR apps for smartphones with Vuforia.

AUGMENTED REALITY APPS The AR apps had different functionalities like: Moving the sun (and the shadows), animating the different floors for visualizing the interiors, changing the material of floor and walls, changing to a non AR mode (visualizing the model with out the target). The target usually was the 2D drawing of the building.

VIRTUAL REALITY APPS AV apps for architectural interiors visualization. With the possibility of navigating through the interior in first person camera with a joystick (3D modeled interiors with global illumination in Unity to get a proper result) or navigating jumping room by room with a menu (only one 360ยบ static image needed for each room).
