Project Description
Motivation: •To redesign the standard axilla crutch for users to combine two individual crutches into one and separate the crutches back into two.
Goals: •Ensure user comfort•Conform to safe medical device conditions
Current Situation •The standard axilla crutch is the current normal
•Customer’s prototype was not load bearing
Deliverables •Functional Prototype•Easily manufactured product•Patent Documentation

Problem Statement
Current State
• Standard axilla crutches• A prototype was developed by Kyra, but
the product is non-load bearing and has no effective connective mechanism
Desired State
• A functional product which is ergonomically friendly, has a quick and intuitive method of connection, and can be marketed to companies
Project Goals
• Perform analysis of standard axilla crutches, crutch patents, and assistive technologies used specifically for lower body injuries
Constraints• Consider Intellectual Property for the
connective mechanism

MSD II REVIEW

Refinement of Project Description
![Page 15: P14042: Una -Crutch](https://reader035.fdocuments.us/reader035/viewer/2022062814/568168ac550346895ddf5bad/html5/thumbnails/15.jpg)
Refined Handle DesignIteration One: Basic shape,destroy rivets to assemble
Iteration Two: Two pieces,design reduces gaps
Iteration Three: Eliminates sharp corners, two pieces,design reduces gaps

Latch Add-on• Option for users who like the original handles• Only one handle is gripped during connected crutch use• More components needed for assembly than handle design• (Iteration Two pictured)

Testing Results
Sliding Button Handle
• Quick connection time• More secure connection• Include magnets?• Users prefer this design
Latch
• Quick connection time• Unsure whether crutches
are connected• Extended handles for
comfort

Project Evaluation
Successes Shortfalls

What We’ve Learned
• Always consider bottlenecks when prototyping• Iterations with a focus on user input are necessary• Communication with the customer is important• Constant check on design drivers• Keep the solution as simple as possible• Compromise between aesthetic appeal and
functionality

Additional Project Deliverables
Functional prototype which will be targeted towards the majority of crutch users and
will be available as a household item.
The product will have an aesthetic appeal
and will have the potential to be
manufactured right away.
