Sport-Specific Terminal Device Challenge
Enable Community Foundation challenges you to design a Specific Terminal Device
ABOUT THIS CHALLENGE
The Enable Community Foundation is seeking to challenge individuals to design a 3D printed sport-specific terminal device (TD) to fit an industry standard transradial prosthetic socket. The TD must attach to the arm at the wrist with the industry standard 1/2 – 20 or hex bolt (that’s imperial, for metric countries it is an M12 fine thread) .
A transradial prosthesis is an artificial limb that replaces an arm missing below the elbow. Please be aware that this challenge is for the TERMINAL DEVICE ONLY and not for the arm.
WE CHALLENGE YOU TO:
Develop a terminal device (TD) specific to a sporting activity that is:
Create a brief video of the device in use (view a sample video). The terminal device can be demonstrated by being screwed to one of the following:
Your entry must include:
Caution: Safety is the number one priority. These terminal devices should NOT be tested on a person with a transradial limb difference. These devices ARE considered experimental concepts. Orthotics and Prosthetics (O&P) practitioners will ultimately have to determine how to use these concepts in designs that are safe and do no unintentional harm.
Design deadline:The deadline for design submissions is April 30th, 2016.
- Submit your design (native format and STEP files) and video! Email [email protected]
Prizes: Winners will be announced in May.
- 1st place: $750
- 2nd place: $500
- 3rd place: $250
Criteria: Designs will be evaluated on: (out of 100 points)
Our Judges Include:
Andreas Bastian is a designer, engineer, and artist who develops and applies cutting edge 3D printing technologies.
Andy Christensen has been active in the 3D printing (aka: additive manufacturing) industry since the early 1990’s, the entire time with a focus on medical applications.
As CEO of Create Prosthetics and Head Clinician for Mountain Orthotic and Prosthetic Services, Jeff specializes in custom and small designs for Adaptive Athlete.
Scott Summit co-founded Bespoke Innovations, Inc. in 2009 and serves as its Chief Technology Officer.
Why 3d printable design? Most professional prosthetics are made to be modular in that the hands are interchangeable with a specific device for a specific use. No one hand does everything well.The ECF is requesting designs for sport specific terminal devices (TD) for transradial upper limb amputees and people with transradial upper limb differences. These TDs will be used as a component attachment for conventional prosthetic sockets. The TD must therefore attach to the arm with the industry standard 1/2 – 20 or hex bolt (that’s imperial, for metric countries it is an M12 fine thread).
A 3D printable design is ideal because 3D printing can easily handle the sort of customized work required for these devices. Additionally, there is a great opportunity to work with professional O&Ps to develop a socket and then allow local designers to build off it to address recipient specific requests such as biking, kayaking, sports, or even specific chores.
We’re going to focus this challenge on fun activities and leave the chores and the more industrial and vocational related tasks to one side for now.
WHAT IS A TERMINAL DEVICE?
A terminal device is the portion of an upper extremity prosthesis that acts as a hand. Terminal devices provide most of the function of the prosthesis and can be disconnected at the wrist to allow the user to switch to a different device.
There are two major types of body powered terminal devices. A voluntary opening (VO) device is held closed by springs or rubber bands and the user moves to open it. This mechanism makes it easy to hold and move objects without effort, but has a grip strength limited to the strength of the springs. A voluntary closing (VC) device is held open by springs and the user moves to close it. This allows for a strong grip but requires effort to hold and move objects.
Devices for this challenge can be either VO or VC devices. They can also be ‘passive’ in that they can be statically attached to the socket and then clamped, ratcheted or strapped on to the sport device. In the case of certain sports such an apparatus might not be needed at all.
WHY DESIGN A USE-SPECIFIC TERMINAL DEVICE?
Expanding from a design focus on wrist-powered hands to arms will allow the e-NABLE volunteer community to move from providing assistive devices to a small percentage of the upper limb difference community to a much larger group of people. By focusing on terminal devices and ornamental fairings, the Enable Community Foundation and the e-NABLE community can provide devices useful to O&P practitioners in the developed world that complement their work without impinging on the clinical areas in which community members are not qualified.
There is a marked and unmet need for function-specific devices that is not served by existing insurance and medical practices. In many cases, these needs are easier to address from a design and fabrication perspective AND yield high returns because they enable fun activities.
We want to make sure that you have all of the information that you need to tackle the challenge. As such, in the first weeks of a challenge we may refine the specifications or offer clarifications based on member feedback. Please ask any questions that you have!
