Challenge for the Mass Mobility Project

Challenge: Dynamic Form Lifestyle Device

Brief for Dynamic Form Lifestyle Device

We invite you to create a mobility device for use by those with permanent or temporary disability, by developing solutions and concepts that are beautiful and envy-invoking functional pieces of design.

We offer that you take inspiration from the new wave of prosthetics on one extreme, or proliferation of eyewear on the other. Personal mass mobility, like eyewear just a short time ago was viewed as medical device. Now eyewear has become an iconic form of self expression and utility, amplifying the relationship between function and design. As you begin your design, take cues from such products and tackle this challenge as a design problem. We ask you to emphasize form, self expression, and social dimensions in your design. Ask yourself: Is this something I would want to use?

As a user-first design approach challenge, understanding and empathizing with the end user is essential. For that reason, collaborating and/or ideally working with a person with disability (PWD), a person who is elderly, or a personal ability needs professional is strongly encouraged.  Please let others know if you'd like to be part of a team and get in touch with our co-pilots.


Above everything else this challenge aims to create a product that people of all abilities look at, admire and even want to use. We've provided the use cases below to help you accomplish this.

Use Cases:

You may design a manual, power assisted, or powered device. Your product design must address at least two (2) of the use cases provided within the challenge brief


Minimum Requirements:

  • Accomplish basic needs such as:
    go in a straight line, go around corners, go over bumps in the road, pass over small cracks and road indentations without becoming stuck

  • Must include major component(s) suitable for high performance metal additive manufacturing

  • Components for metal additive manufacturing should justify manufacturing by additive methods and satisfy design requirements. 
    (E.g, total product weight is reduced when this part is generatively designed, traditional manufacturing methods cannot be used effectively, the part fails frequently and needs to be replaced or adjusted; the part should best be tailor made to fit the customer, to provide more functionality like modularity, etc.)

  • Multi-terrain suitable

  • Ability to adjust position of drive controls or similar on powered device

  • Ability to adjust arm, leg, foot support height if applicable

  • Be able to transfer in and out easily - both self transfer or assisted transfer.
    An easy transfer is defined by: no tools required, a method or modality for moving or removing or folding components for transfer e.g.: lifting armrest, removing side guards, and easy use of transfer boards or functional equivalent if needed.

Space requirements:

  • Must be able to go through a common household door frame 32" (81 cm) wide

  • 3” (7.5 cm) minimum ground clearance


  • Modular components/adaptable for special needs or use cases - though the device will be primarily a manual device you may design a electric modular add-on component.

  • Provisions for computer assisted steering and stabilization (e.g. gyroscope)

  • Lighting systems for design or function

  • Customization kits

  • Smartphone, tablet, and adaptive peripherals interfaces

  • Storage solutions (backpacks with arms, autonomous trailers)

Space-related Considerations:

  • Common bathroom door width: A standard bathroom door is 32” (81 cm) this can come down to 24” (61 cm) as an absolute minimum

  • Common Sedan trunk size dimensions: 12 - 15 cubic ft (0.34 - 0.42 m3

  • Common shopping aisle size width: 36” (91 cm)

  • Common shopping counter height: 36” (91 cm)

  • Common table height: 30” (76 cm)

  • Common bar height: 42” (107 cm)– 45” (114 cm)

Component requirements:

  • Components include: Seat, footrest and armrests and wheels

  • Your product design base does not need to follow the components within a current wheelchair but you must include modular add-ons of these components for the users who want/need them. Examples of this include: choosing to design your lifestyle device with a saddle seat.

Weight requirements:

  • Weight capacity: up to 350 lbs / 160 kg weight

  • Product Weight:

    • Individual Components: no more than 55 lbs / 25 kg - goal weight would be less than 33 lbs / 15 kg

    • Manual (or electric assist): device can be no more than 60 lbs / 27 kg

    • Power: device can be no more than 250 lbs / 113 kg not including battery 


Document Deliverables:

Entries must be in English, in PDF report format, no more than 20 pages and should contain the following information and elements:  

  • Executive summary: a brief description (500 words) of the proposed solution.

  • Detailed description of the proposed solution, including:

    • Key specifications (such as weight, height, width, battery life if applicable, etc.) and significant design elements that are integral to the efficacy of your entry

    • Drawings, including identification of major design dimensions and significant design elements (such as modular components or power components)

    • Description of how your proposed solution works

    • The 2 use cases your solution addresses, including how you chose these use cases, how your solution is adapted to address the use cases, and the efficacy of your solution for each of the use cases

    • An analysis of how your solution will yield accessibility to a wide variety of individuals

  • Materials specifications and process recommendations for significant parts that are integral to your entry (such as the metal part(s) you specify as being additively manufactured) - remember you can always reach out to co-pilots with questions. 

  • Specialized technologies or materials that are important for your device

  • The inspiration for your work

  • Your experience, background and capabilities (and your Team's, where relevant) including relevant past projects and experiences, and the name of each team member

If the solution involves software content, the pseudo-code should be provided. (This can be counted outside the 20-page limit)

Visual File Deliverables:

Annotated imagery (JPEG or PNG of at least 1920x1080) in isometric ("perspective") and third-angle (top, side, and plan) views for:

  • Full assembly and all subassemblies

  • Illustrations showing at least 2 use cases

CAD Files

  • CAD files for complete solution assembly and all sub-assemblies in both native and neutral formats (.step and/or .stp file extensions) -- see “Resources” below for links to free CAD software and tutorials!

  • Materials specifications and process recommendations for significant parts that are integral to the efficacy of your entry (such as the part(s) you specify as being additively manufactured)

Additional deliverable recommendations: While not required, a more detailed entry will be judged more favorably when it comes to scale modeling, proof-of-concepting, and prototyping:

  • Circuit diagrams and specifications for any electronic components

  • Bill of materials, vendor examples, other useful references.
