1st concern for innovation The Cause – Earlier Case Study

slide-4
SLIDE 4

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

SLIDE 5

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

SUGGESTIONS GIVEN BY JAWANS

slide-22
SLIDE 22

To design a water bottle that:

  • 1. should be easy

y to filte ter

  • 2. should have an integ

egra ral l pump mp

  • 3. should be easy

y to main intai tain and not smell ell

  • 4. should store 2

2 litre tre of water er

  • 5. should be sound

ndpro roof

  • f
  • 6. should be suitable to carry in the side

e pocket kets s or inside side the bag ag

  • 7. Should cost

t tha han INR 2000

User feedback of final design

slide-48
SLIDE 48

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
  • f the bottle eliminated so that the cap fits the

shoulder of the bottle.

  • Better locking mechanism for base cap.
