Experience TEAM MEMBER AT Brighton Product Lab 2019 I was a design team member who was responsible in creating sketches, 3D CAD models and presentation spreads by using Adobe creative suite, Solidworks and keyshot rendering. The design consultancy has been mainly working on packaging and fitness products.

CAD Designer intern at United bike company 2017- 2018 Responsibilities include communicating with manager and team riders to come out with new ideas, construct 3D and 2D CAD models of possible new bike parts. Helping the company to explain designs to manufacturers overseas to get prototypes made.

Event staff for a summer promotion project by UBER 2015 Uber was introducing a new feature on their mobile application, which allowed people to order icecream via the app during the humid summer days. My main job was to assist the initial stage of the project by communicating with assigned driver and customers.

Dear Chris I am interested in joining the footwear design team at Fitflop and eager to learn everything about the design process in footwear industry, from mood-boards to sketches to CAD to communicating with manufacturers.

I am a product design graduate with a passion for footwear, my final year project attached in the portfolio was based around a modular shoe that can be assembled and detached at home by wearers for easy repairing and customisation. My design can also achieve closed loop recycling since sustainability is a big topic.

During the design process I have made multiple working models for testing with hands-on pattern making, 3D/2D CAD modelling and 3D printing. I hope my design skills can assist to drive the creative direction of your team.

During my work placement as a CAD designer, I have learned to work at a fast pace environment with a solution oriented and ‘can-do’ attitude. I enjoy working as a team and witnessing myself overcoming challenges, so I’ll be looking forward to joining the creative journey with Fitflop.

Sincerely, Jeremy

CUSHIONING ISSUE It was found that material stiffness is not the only variable for shock absorbtion of the shoe. Correct placement of cushioning material is just as important, since outsoles with different thickness distributes impact differently. Stiffness of exisiting shoe soles varies between Shore A52-92 (CesEdupack) The thickest and softest outsole doesn’t directly result to be the most impact absorbent.

In order to provide shock absorbsion for wearers feet with an outsole that can separate into 3 parts, it is important to not place parting lines of outsole segments under those pressure points.

On the left is a pressure distribution map showing peak pressure points (darkest areas) occur to feet while running with different type of shoe soles (Shorten, 2000)

(a) Thin (b) Moderate (c) Thick

Balancing comfort and modularity The detachable feature of the shoe have made the design very complicated. In order to make a thin outsole to perform well at absorbing impact, multiple material reinforcement is needed.

Therefore, to balance the detachable feature but not sacrificing the fundimental function of shoe sole to be shock absorbent, outsole will be made of one single material with a thicker profile in moderate stiffness of Shore A65.

Impact hotspots Concept outsoles’ split lines

SOLUTION This concept will be the most appropriate for thick and well cushioned outsoles.

Splitlines are located in low impact areas and high impact areas are well within the centre of the outsole margin.

minimally cushioned

moderately cushioned

well cushioned

FLEXIBILITY ISSUE After wear test, it was found out that the split lines constructed referencing to cushioning effectiveness is not enough. Although prototype’s function remained intact, one of the locking hinges torn from fatigue because the original sole design failed to provide adequate flexibility required between the Metatarsal bones and Phalanges on the lateral side of the foot while walking and running.

Breakage found on lateral side

Iteration

SOLUTION 1 Phalanges

Lateral Approach

SOLUTION 2 Add ribs to reinforce areas where breakage occured.

SOLUTION 3 To further improve the flexibility of the sole, grooves are added to the toe area to relief mechanical stress Improving walking comfort Improving durability of shoe sole

Medial

The split line have been moved to the area where the prototype was torn, which means that the joints between Metatarsal bones and Phalanges on the lateral side are now on top of the split line. User’s feet would be less restricted when walking and that particular area of the sole is under less mechanical stress.

Outcome

Metatarsal bones

SOLE-UPPER BOND

Each shoe consists 14 mechanical clasps that securely fasten the shoe sole with the shoe upper without using glue, cords, stitching or any form of permanent fixture. Outsole, midsole and bonding mechanism were made of a uniform material TPU, which simplifies recycling process.

TESTING

During tensile machine testing, the sole-upper interlocking mechanism withstood one 170 Newtons of tensile load without showing permanent deformation.
