Ergonomic Salad Tongs

Role:

Ergonomic Analysis, User Interviews, CAD

Timeline:

3 weeks

Tools:

Fusion 360

Challenge:

Along with a team of two others, we used task analysis, anthropometrics and ergonomics to make standard kitchen tongs better and easier to use.

Considerations:

  • Ease of use

  • Fine control over tool

  • Ease of adjustments to grip

  • Fit (even pressure distribution across palm, and fingers)

Insights:

  • Users unanimously preferred when it was obvious which side of the tongs their thumb should be placed on, so we made a well-defined thumb groove on the grips.

  • Users didn't feel the same about non-thumb fingers, as specific grooves for all other fingers often confused users as to where and how exactly to place their fingers, especially because hand sizes varied so much. 

  • We learned to balance the tradeoffs between ease of use, comfort, and accessibility for users with different hand sizes, which were all conflicting factors.

Process:

1. Task Analysis

2. Anthropometrics Analysis

3. Ideation

4. Foam Prototypes (6)

5. User Testing

6. Qualitative Ergonomic Analysis

7. User Testing (round 2)

8. Final CAD
