Although some creative minds have come up with some solutions to carry things while on crutches, these tend to be not too practical.
The criteria for your design challenge are:
Be safe to use
Weigh less than 2 pounds (~1 kg)
Carry a minimum of 4 pounds (~2 kg)
Attach to a pair of crutches (or an individual crutch)
Be easily removable
Your end user has requested that the device be able to organize and carry:
three notebooks
school supplies (pencils, erasers, etc.)
Personal items (headphones, phone, wallet, keys, etc.)
You are constrained by material accessibility and time. Your completed device must be ready before the february break.
Create a document with your team where you define the Criteria and Constraints for this challenge. You may copy/paste the ones above but you must also ADD what your team personally identified. Embed the document in your portfolio under the problem statement
