MA TRIZ Certification Level 1 Training (Part 2)

I attended MA TRIZ Certification Level 1 Training on 19, 20, 26 & 27 April 2013 which organized by Institute of Systematic Innovation, Hong Kong. I would like to summarize my study below for sharing.

Dr. Michael YH Li (Certified TRIZ Specialist, MA TRIZ Level 3) was our trainer and he introduced the course schedule as follows.

Day 1 (19 April 2013)
- Introduction of TRIZ
- Multi-screen Thinking - The Nine Windows
- Ideality and Ideal Final Result
- Function Analysis
Day 2 (20 April 2013)
- Cause Effect Chain Analysis
- Trimming
- Technical and Physical Contradiction
Day 3 (26 April 2013)
- Technical and Physical Contradiction
- 40 Inventive Principles
Day 4 (27 April 2013)
- Feature Transfer
- Function Oriented Search
- Introduction to Standard Inventive Solution
- TRIZ for Patent Strategies

Day 3 (26 April 2013)

A group photo for all classmates in TRIZ Level 1 was took.

Dr. Li continued to the technical contradiction and briefed 39 generalised parameters. We needed to choose the one which had the closest similar meaning to the specific parameters (Divergent). Then Contradiction Matrix was to select different inventive principle to find the generic solution. After that specific solution was identified through analogical though from generic solution (Convergent)

39 Engineering Parameters were shown in the following table.

Then Dr. Li explained 40 Principles one by one and it showed as following table.

Some examples were showed below.
Inventive Principle 7 - Nesting (Nested Doll): Chair are nested inside chair

Invention Principle 22 - Convert Harm into Benefit: Sandwich bag had fake mold printed on it to discourage thieves (http://boingboing.net/2008/09/16/sandwich-bag-has-fak.html).

Inventive Principle 24 - Mediator: Use paper ring as mediator to avoid heat of coffee cup.

Inventive Principle 32 - Color Changes: The liquid inside the bulb of fire sprinkler used color code to indicate the different temperature classification.
Inventive Principle 37 - Thermal Expansion: The fire sprinkler worked when bulb broke as a result of the thermal expansion of the liquid inside the bulb.

The following diagram showed how to use the Contradiction Matrix.

Dr. Li then introduced how to use Physical Contradiction to solve a problem. Physical Contradictions are some aspects of the product must have two opposing state. Something must increase, the same parameter must decrease. It was formulated for physical parameters which can be resolved in time, space, affiliation, and system hierarchy.

There are three types of methods to solve physical contradictions.
- Separating contradictory demands (included separation in Space, Time, Relation & System Level)
- Satisfying contradictory demands
- Bypassing contradictory demands

Day 4 (27 April 2013)

In the last day of TRIZ training course, Dr. Li introduced Feature Transfer, which was an analytical tool for improvement of the base system by transferring relevant features (say properties, characteristic, etc.) from the alternative system.

After that Dr. Li briefed the Substance-Field Standard Solutions using Substance-Field Model (Su-Field Model). There are 76 generalized model of standard inventive solution which would be included in TRIZ Level 2 training.

The last topic was TRIZ for Patent Strategies. The goal of Competitive Patent Circumvention is to legally circumvent the constraints imposed by competitive patents through applying Function Analysis, Cause Effect Chains Analysis and Trimming. It is at least one subsystem (component) must be removed.
