Ice cream scoop design by Prof. Karl Ulrich
- 1. Design: Creation of artifacts in society A course taught by Prof. Karl Ulrich of Wharton Oct 22- Dec 17, 2012 @ coursera.org Designing a better ice-cream scoop Prepared by: Vinay Dabholkar, vinay@catalign.com
- 2. The process
- 3. Problem area: ice-cream scoop
- 4. Defining the problem at the right level Why-How technique
- 5. Identify gap through observations (1/2) Prof. Ulrich’s son scoops ice-cream at home
- 6. Identify gap through observations (2/2) 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.
- 7. Concept generation (1/2) Method: decomposition by function
- 8. Concept generation (2/2) Generate 10 concepts by combining ideas
- 9. Concept selection matrix Select 4 concepts
- 10. Prototyping tools 1. Wooden pieces 2. Sheet metal 3. Saw 4. Empty cans 5. Baseball bat head 6. Cutter 7. Hammer 8. Sandpaper 9. Ice cream scoops 1 3 6 8 9 4 5 7 2
- 11. Prototypes B C D A
- 12. Testing the prototypes A B C Scoop #5: Created from a mistake during prototyping D E
- 13. Testing the prototypes: Prof. Ulrich’s son Top 2 selected prototypes (C & E)
- 14. Balsa foam model Modified prototype E (Angled scoop)
- 15. 3-D printed angled scoop
- 16. Testing of the 3D-printed angled scoop “It’s super-nice” – Prof. Ulrich’s son Only problem: ice cream sticks to the material
