Role
Headrest Subassembly Mechanical Engineer
Technologies
Injection Molding
Manufacturing
Asia
Master Modeling Structure
Skeleton motion of all datums
Master modeling of each subassembly
Headrest, base, shell
Form came as 2D sketches from industrial design
Fully surfaced model
High fidelity machined prototype (FTV and FTC)
Tooling release
Fit to Vehicle and Fit to Child Validation Testing
Due to the nature of this car seat, I developed a full fit to vehicle SOP for checking all possible configurations in all guaranteed vehicles
Artisan dolls and real life kids testing fit to child to validate user experience
Crash Testing
Engineering builds used for crash testing (injury values)
Mockups on engineering builds using plastic, nails, screws, wood of any mockups for tooling changes
Tooling changes usually driven by user experience learnings, crash testing values, or assembly part fit and finish
