Semi-processed
Material
Misalignment

3. Problem Statement
Semi-processed material misaligned
after pass-through hot furnace
Material Aligned
Material
Misaligned
Assumption:
• The semi-processed material consisted of different types of
material (i.e. thermal coefficient, and expansion rate are
different)
• The furnace is used as material hot tempered process where it

4. Function Analysis

5. Cause & Effect Chain
Analysis

6. Engineering Contradiction
Parameter involved:
Improved parameter : Temperature (#17)
Worsening Parameter : Measurement accuracy (#28),
Manufacturing precision (#29)
If I increased the heating/cooling temperature, the material is
completely melt/harden the material, but ultimately it will cause
material misalignment.

7. Inventive Principle # 24
Intermediary
DRAWBACKS:
 Increase the production cost to design and prepare the jig/cap/clipper
 Decrease the productivity because the jig/cap/clipper needs to be
attached on the semi-processed material prior load to the furnace
input

8. Physical Contradiction
High Temperature
(to melt the
material)
Low temperature
(to harden the
material)
Control
parameter:
Temperature
In Relation (Upon Condition)
• The furnace is hot if I want to melt the semi-processed material
• The furnace is cold if I want to cool down the semi-processed
material

Adding Tracking
System

16. New MPV
 Tracking system
◦ On-time update for the location of the patient
to the nearest hospital.
◦ Additional sensors can be added to the
tracking system to monitor the on-time
condition of the patient.
◦ The tracking system can also help to provide
the exact location of the patient for the nearest
transportation services.
◦ The tracking system is also able to build up
the network for the users.

1-Card

18. Cards

19. Problem Statement
When the customers apply the membership cards from
different retail shops, they will faced the problem of too
many cards in their wallet or purse.
What are the main and interaction causes that the customers
apply so many membership cards?

20. Solving the Problem with TRIZ
Original Problem
to resolve
• Too many loyalty cards
• Heavy wallet or purse
Function
Analysis
• To think about how to stop a harmful action being harmful: too
many membership cards cause heavy wallet or purse.
Cause & Effect
Chain Analysis
• To find the potential fundamental root causes
• Use 39 System Parameters mixed with some of the 40 principles
of the contradiction Matrix.

21. Engineering
Contradiction
• If I increase the number of membership cards, then it’s will
provide more benefits but it ultimately consumers more
space (wallet or purse).
Contradiction
Matrix
• To identify the System Parameters which improve and
worsen; and use the Contradiction Matrix to identify
potential Inventive Principles to help solve the problem.
Special Inventive
Principle
• Once the improving and worsening System Parameters are
identified, then the Contradiction Matrix is used to generate
potential Inventive Principle solutions.

22. Cause & Effect Chain Analysis
Too many membership cards in
the wallet or purse
Provide special and
differentiated service
to best customers
Enhance the
overall value-

product or service
Turn a profit

24. Benefits and Impacts of the Solution
No more bulky wallet or
pocket, carry only one card for
different retail shop on different
loyalty programs
Internet loyalty programs can be deployed across
multiple vendors and the card acts as a secure
central depository for points or rewards.
Easy to track the due date for different
loyalty programs
