1st concern for innovation The Cause – Earlier Case Study

Chakku’s 7Cs: 1. The Cause – The concern to solve a problem. 2. The Context – Understanding the problem space and the environment. 3. The Comprehension – Arriving at design insights. 4. The Check – Creating a list of key requirements as a check-list/product brief. 5. The Conception – Generating multiple ideas and combining them into concepts. 6. The Crafting – Converting the selected concept in to mock-ups, functional prototypes and mass production. 7. The Connection – Creating user satisfaction and delight

The Context - Understanding the User and the Scenario • Circumstances in which the problem exists. • The environment surrounding the problem space including the social and cultural aspects. • The socio economic structures that surround the user scenario

User feedback of final design

User suggestions: • The handle of the pump should be more strong • Filter should be vertical rather than horizontally as it is time consuming. • Thread of the bottle can be reduced and the neck of the bottle eliminated so that the cap fits the shoulder of the bottle. • Better locking mechanism for base cap.
