Research showed women focused on areas outside the path more often than men, reflecting their broad experience with fear of crime, particularly personally violent or sexual crimes resulting from stalking, prowling, or loitering in poorly lit areas. (https://doi.org/10.1089/ vio.2023.0027)

Tanky

The Urban All-terrain Walking Augmenting Shoes

Note: MSc Integrated Industrial design major project.

Individual work.

Redesign of a novel personal electric vehicle Tanky is a redesign of the Moonwalkers with the aim to improve the comfort and stability on urban pavements such as cobbles.

Exploring the brief This project has an open brief. Therefore, I chose the topic I am interested in - personal mobility. After conducted a series of research and selection, the brief converged from "A product that improves the commuting experience for public transportation users." to a more refined "Redesigning walking augmenting shoes (Moonwalkers shoes) for cobblestone surface."

Improving the commuting experience? →Needs of commuters: • Portability is critical less stress for transit, parking, storing.

• Easy maintenance • Better be motorised

Moonwalkers are a pair of novel "walking enhancing shoes" that was released in 2023. It's adaptive AI drivetrain controls DC motors to increases users' walking speed up to 2.5 times without the need of any remote controller.

Preliminary research about commuters' needs. Qualitative data collected from online forums and research papers.

Moonwalkers walking augmenting shoes scored the highest. → Redesigning Moonwalkers shoes is the path forward.

My benchmark product: The Moonwalkers walking augmenting shoes by Shift Robotics.

Surveying 5 types of personal vehicle products available, including folding ebikes, folding bikes, e-scooters, e-skateboards, Moonwalkers shoes.

Analysis and comparism of the 5 types of personal vehicles based on portability, road safety, ease of maintenance, comfortness...etc.

Refining the design challenge New brief: A Moonwalker-inspired walking augmenting shoes for rough urban pavements like cobbestone.

Detailed reseach and critique of the Moonwalkers shoes were conducted to identify the pros and cons, or underlying design opportunities of the product.

Research of relevant technology and performance requirement of the for developing Tanky's wheel system.

Prototype of Tanky's wheel system

Prototyping and Testing Model of the Moonwalkers and Tanky's wheels are made at 1:1 scale. Both designs are tested on the same controlled cobble surface.

Performance are captured by a bespoke arduino accelerometer/gyroscope data logger; then compared with each other after data processing.

Optimised Arduino accelerometer/ gyroscope data logger.

Each wheel design was tested 30 times on the same track.

Raw accecleration/ gyroscope data collected every 2 millisecond in each test.

Data processing with python. Obtaining pitch/ roll data, plotting, statistical summary...etc.

Plots and aggregate data ready for analysis and comparism.

Results Tanky is able to significantly reduce and smooth out the impact the user feels when walking on cobbles. Providing users with a more comfortable and confident experience when walking on rough pavements.

* Both designs are tested on different surfaces iteratively for 30 times. It's observed that with Tanky, the standard deviation of vertical acceleration is on average 343% lower, and the maximum vertical accleration is 242% lower. * Plots above are randomly picked out of the total 120 tests to demonstrate that unlike Tanky, Moonwalkers' vertical accelerations on cobbles are significantly higher to its own values on flat grunds.

* Both designs are tested on different surfaces iteratively for 30 times. It's observed that with Tanky, changes in both side tilting and front-rear tilting are less dramatic

Finalising the design After verifying the performance of the airless tires + tank track design, further design tweaks were made. Focus group discussion was held to gather user aesthetic preference and opinion.

The design of Tanky was finalised with cost estimation and updated Product Design Specification documentation.

Cost estimated to be around ￡500. Both offthe-shelf parts and manufacturing cost are considered.

Several potential flaws were discovered after tested with the physical model. Changes are made in the CAD to reflect those discoveries.

Focus group discussion provided valuable user opinions regarding the product aesthetic preference.

Easily Reused & Recycled Reuse the can for sugar, oat, flours or other dry products.

The PP lid and aluminum can are easily seperated and can both be recycled. Unlike the commonly seen composite pouch made with plastic, paper, and aluminium foil which is generally not recycled.

Project Draw/ Pin Maximum convenience in all paying scenarios for all users with Draw - coin sorting case/ Pin - modular wallet.

Note: Indepedent project.

Cash payments are common According to government data*, 37.9% of spending in Taiwan are still done by cash in 2023.

Therefore, everyone still carries both cash and cards when going out, making wallet an indispensable accessory for different payment scenario.

Phase I - Draw focused on making coin accessing and receiving faster and easier, since “coin economics” like night markets and street foods are important parts in Taiwanese people’s life.

Phase II - Pin focused on designing an open source modular leather bifold wallet that adapts and evolves, empowering users to develop the wallet that best suits their habit.

Everyday shopping scenario require different methods of payment, some are strictly cash-only.

User Survey for Phase I - Draw(n=50) •

Ideation and prototype of the coin sorting case

Despite innovative wallets are widely available, almost all of them either make users store coins in a simple pouch compartment, or tell users to find another container.

•

45% of participants store their coins in another container or their pocket; separate from their wallets.

•

On average, people carry 7.7 coins with them when going out.

•

Coin case is a relevant product with actual need.

•

The container should be able to contain at least 8 coins with various sizes.
