5. Mind Map
Goal
To list the problem areas related to water wastage
and pollution in iit guwahati that we found in our field
research and come out with early ideas related to
identified problem areas

6. Research
“ Design Brief: After our field research we decided to work in the area of
water wastage in the hostel mess of IIT Guwahati during washing of
utensils.
”
Research was done to understand user needs, problems and goals.

7. Activity Observation
Goal
To observe all the activities of mess workers while
cleaning the dishes to figure the possible ways to save
water in the process.

8. User Interview
Goal
To know the problems faced by the mess workers in
IITG, to make a solution that fits their needs and goals.

9. Analysis & Ideation
“ Analysis of user research current existing scenario, problem
exsiting and come out with new ideas forms etc for a product
”
that could solve these existing problems.

10. Use Case
Goal
To understand current method of washing utensils
completely by dividing it into smaller steps and get the
purpose, advantages, disadvantages and better sub-
stitude for each step.

11. Affinity Diagram
Goal
To list down the factors that are needed to be consid-
ered while conceptulization the final idea for the prod-
uct like functionalities, hygiene, ergonomics, time and
material.

12. Doodling
Goal
Sketched different concepts and tried out various con-
cepts to explore various forms and finalize an ergo-
nomic form which would fit mess worker’s hands
while washing utensils

14. Scenario
Functioning
Step1: The person will hold the pipe and rotate the
Shcrubber upside down to let the water come out for
initial wetting of utensils. Then he will rotate it back to
switch off the water outlet.
Step 2: Now he can pour out some liquid soap from
Shcrubber on utensils by pressing the button of the
liquid soap compartment.
Step 3: He can use the scrubber present on the other
side for cleaning utensils by rubbing them.
Step 4: At the end, he can wash by pouring water
again from the shower side of shcrubber.In this whole
process a lot of water is saved as while crubbing no
water is used unlike previously where the taps were
constatntly running.

16. CAD Rendering
Goal
A 3D model of our product to know how our final prod-
uct would like and to make it easy to protype.

17. Prototyping
The Making
Step 1 : Making of Plaster of Paris mould for shower
Step 2 : Vaccum forming of styrene sheet]
Step 3 : Soap compartment and walls for scrubber
Step 4 : Pipe and Button
Step 5 : Putty and Color spray

19. User Testing
“ A user testing was done to find out good and bad points of the
”
product.
Sh crubber
20. User Testing
Results
By user testing, we found out that Shcrubber could be
a nice solution for saving water in hostels mess of IIT
Guwahati but it still needs some improvements be-
cause there might be difficulties while washing
glasses, bowls and corners of plate using it. This
could be a start of our water saving efforts.
