ARM4ALL Design Contest

SOLIDWORKS partners with the Ellen Meadows Prosthetic Hand Foundation for the ARM4ALL Design Contest! Make a difference in the world by designing the next generation mechanical below and above elbow device that complements LN4’s prosthetic hand.

SOLIDWORKS and LN4 Foundation

Over 13 million people around the world have forearm amputations. A prosthetic hand is an invaluable asset to individuals without upper limbs. The Ellen Meadows Prosthetic Hand Foundation’s (LN4HandProject) mission is to help restore functionality in people who suffer from diseases requiring amputation or who lost limbs in traumatic incidents. Over the past 16 years, the LN4 Hand Foundation has delivered 60,000 low-cost, light, durable, functional prosthetic hands based on a pre-CAD design.

For the past few years, we, at SOLIDWORKS, have been working with LN4 in order to help them provide free mechanical prosthetic hands for all who need them, anywhere in the world. A team of SOLIDWORKS employees recently designed this next-generation prosthetic hand for them.


This year, 3DEXPERIENCE Works For Good, in partnership with the LN4 Hand Foundation, is launching the ARM4ALL design contest, which aims at helping LN4 produce a new below and above elbow device, complementary to the new LN4’s hand. And we want to enroll any students in our 3DEXPERIENCE Works For Good action through this design contest.


Design a next generation mechanical above and below elbow device (with no electrical/electronic piece) that should get fixed to the new prosthetic hand that LN4 Foundation distributes (see the specifications tab).


Step 1: Register to the design contest.
Step 2: Download your license here.
Step 3: Design taking the provided specifications into account.
Step 4 : Upload your content:name – Project pitch (text) + 4 to 8 pictures+videos (can be Youtube or Vimeo).
