DESCRIPTION
This is a short description of how Prof. Karl Ulrich of Wharton went about designing ice cream scoop in the design course he taught at coursera.org.TRANSCRIPT

Designing a better ice-cream scoop
Prepared by: Vinay Dabholkar, [email protected]
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.
Identify gap through observations (2/2)
Concept generation (1/2)
Method: decomposition by function
Generate 10 concepts by combining ideas

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

Fantastic course – Highly recommended
