2. Part 1
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

9. Inventive Principle # 35
(Parameter Changes)
Temperature Transition
