TRIZ

1. What is Triz ?

   • Founder : Genrich Altshuller in 1946
   • Improvise existing system
   • Applicable in many growing industries and domestic use
   • Inventive problem solving based on logical analysis & innovation trends in global patent

2. Function Analysis

   • Analytical tool to determine the components of a technical system & its functional relationship
   • Engineering System = Involves components, super system and object.
   • Interactions
     • Equal or Normal
     • Insufficient
     • Excessive
     • Harmful
   • Component Analysis Interaction Analysis Function Model

3. System Parameter

   • Defining characteristics of components
   • Involve 39 parameters eg.speed , force , shape

4. Trimming

   • Method to increase efficiency & reduce cost of engineering system.
   • Trimming Rule eg. Function of toothbrush - remove plaque from teeth (Rule C)
     • RULE A Function not exists & no Function needed
     • RULE B being worked by the Function Performs itself
     • RULE C Function transferred to Component in the System or Supersystem

5. Cause & Effect Chain Analysis (CECA)

   • Inspecting the source or source of an unwanted effect
   • Reveal a root cause of a problem, create new ideas and find the best solution to the problem.
   • Process
     • 1st : start off with the original problems / unwanted effects.
     • 2nd : identify the high level causes. For each high level cause, identify the next level cause by asking the next “why”.

6. 40 Inventive Principles

   • The solution resolving this engineering contradiction is inherently a creative or innovative solution eg.segmentation , universality

7. TESE S-Curve

   • TESE - tool in S-curve to evaluate the trend and evolutions in engineering system
     • O= OVERVIEW I= INDICATOR E= EXAMPLES R =RECOMMENDATION
     • First Stage = Product born Transition Stage Second Stage = Evolution/ Progress stage Third Stage = Product Maturity/ Stable Fourth Stage = Monotonous
   • S-CURVE
     • Evaluate product defects/weakness based on feedback.
     • Trigger the inventor to propose an options or alternative in rejuvenating product
     • Determine the life spam or demand toward product.
     • Formulate/establish most potential strategies

8. Engineering Contradiction

   • MV - manipulated variable eg. temperature, density, thickness
   • +ve MV : Positive impact/improvement from MV.
   • -ve MV : Worsening impact that we have from what happen in MV.
