2. (B) As energy usage becomes more acute and
expensive, there are many efforts to
reduce its usage cost especially in the
home. If you consider a typical house, how
would you reduce energy usage if you are
cost constrained i.e. the solution(s) needs
to be low cost and yet effective.

TORIZU 4

5. Cause and effect chain
Home energy
usage is high
Home appliances
consume a lot of
energy
Home appliances
are not well design
and not use energy
efficiently
Home appliances
utilize energy
independently
without a
complete solution
Human factor
Lack of concern

6. Engineering Contradiction
 IF we want to reduce energy usage
THEN power consumption can be improve
BUT temperature cannot be maintain at a
desired level
 Improving parameter : #21 = Power
Worsening parameter : #17 = Temperature
Possible Solution : #2, #14, # 17, # 25
Chosen solution : #25 = Self service

18.  IF we set fire and burn the area openly
THEN we can clear the land for plantation
in a fast, cheap and easy way
BUT harmful particles will be released which
formed haze
 Improving parameter : #33 = Ease of
Operation
Worsening parameter : #30 = Object-affected

Possible Solution : #2, #25, #28, #39
Chosen Solution : #28 = Mechanics
