Semi-processed

Material

Misalignment

Problem StatementSemi-processed material misaligned

after pass-through hot furnaceMaterial 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

can heat and cool down to harden the material.

Function Analysis

Cause & Effect Chain

Analysis

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.

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

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

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.

Part 3

1-Card

Cards

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?

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.

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.

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

Preliminary action (Prior action – “Do it in advance”)

Figure 1: Membership card using Data Bank

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
