Designing a better ice-cream scoop

Prepared by: Vinay Dabholkar, vinay@catalign.com

The process

Problem area: ice-cream scoop

Defining the problem at the right level Why-How technique

Identify gap through observations (1/2)

Prof. Ulrich’s son scoops ice-cream at home

1. He can’t find the scoop 2. He doesn’t know where the scoop is 3. He tries three drawers before finding the scoop 4. He’s gripping the scoop like a plunger, pinky facing downward 5. He says he can better apply leverage with his thumb than his fingers. 6. He’s using scraping action to create curls of ice-cream, because ice cream is hard. 7. A chunk of ice cream goes flying off in the air, but actually lands in the bowl. 8. He runs hot water on the scoop again, because he believes it needs to be heated up again.

Testing the prototypes: Prof. Ulrich’s son

Top 2 selected prototypes (C & E)

Balsa foam model

Modified prototype E (Angled scoop)

3-D printed angled scoop

Testing of the 3D-printed angled scoop “It’s super-nice” – Prof. Ulrich’s son Only problem: ice cream sticks to the material
