01 — Problem & Goal
What problem were you solving?
✏️ Write this section yourself
Describe the problem brief from your sponsor. What limitations did existing rollator walkers have? What were the key design requirements — portability, load capacity, ease of use for the target user? What made this a meaningful engineering challenge?
02 — My Role
How did you contribute?
✏️ Write this section yourself
You led both the team and the CAD development. Describe what that looked like in practice — how you divided work, how you kept the project on track, how you coordinated with the sponsor, and what specific design decisions you owned.
03 — Process & Methods
How did you get there?
✏️ Write this section yourself
Walk through your design process — concept sketches, early prototypes, design iterations, key engineering decisions (materials, mechanisms, collapsing joint design), and how you validated the design against requirements.

04 — Outcome & Results
What did you build, and did it work?
✏️ Write this section yourself
Describe the final prototype — dimensions, weight, collapsing mechanism. How did it perform against the requirements? What did testing reveal? What would you do differently? Any sponsor feedback or grade/recognition worth noting?
