MA TRIZ Certification Level 2 Training (Part 2)

I attended MA TRIZ Certification Level 2 Training on 18, 19, 25 & 26 May 2015 which organized by Institute of Systematic Innovation, Hong Kong from 9:00am to 9:00pm and instructed by Prof. D. Daniel Sheu. I would like to summarize my study below for sharing.

Prof. D. Daniel Sheu briefed the course outline and he said the original course duration was 5 day. We concentrated into 4 days and elements as follows.

Day 1 (18 May 2015)
- Level 1 Key Points Brief Review
- Overview of Level 2 Tools
- Feature Transfer
Day 2 (19 May 2015)
- Resources Searching
- Modeling Problems and Solutions
- Standard Inventive Solution
Day 3 (25 May 2015) (original Day 3 & 4)
- Introduction to ARIZ (Algorithm for Inventive Problem Solving)
Day 4 (26 May 2015) (original Day 5)
- Pragmatic S-Curve Analysis
- Key-point Review
- Summary & Exam

Day 3 (25 May 2015)
In the beginning, Prof. Sheu helped us to review some items in which we did not fully understand such as Physical Contradiction about “Separation in Relation” and the window, which allowed air penetration but block of sun light, was employed as example. After that the algorithm of ARIZ was explained.

ARIZ stands for “Algorithm for Inventive Problem Solving” which was developed by Altshuller. There are many generations included ARIZ-61, ARIZ-64, ARIZ-69, ARIZ-71, ARIZ-75, ARIZ-77 and ARIZ-85 (the last and stable version). The following diagram showed the two direction led by ARIZ. The first direction is like a converging funnel which transforms from unclear and fuzzy initial engineering situation to a very well-defined model of the problem (e.g. Physical Contradiction). The second direction is like a diverging funnel which expanded from limited resources to more resources.

The Algorithm of ARIZ has three main categories with nine parts. Each part consists of many sub-steps.

Cat. I – Restructuring the Original Problem
Part 0. Problem Descriptions & Identification0.1 Project Statement (Project Title, Descriptions and Picture/Diagram of the system)
0.2 Function Analysis for the System (the bigger picture)

1.0 Analyze the System
1.1 ID the main function of the problematic system and list major parts (in system & super-system)
Identify Mini-Problem included Engineering Contradiction (EC-1) and (EC-2) in opposition.
The Mini-Problem statement is showed as follow.
It is necessary to __________ with minimal changes to the system. (Combining the good of EC-1 and EC-2)
1.2 To define the tool and the product. (Reformulate the ECs into Su-Field models of the conflict)
1.3 Graphic presentation of EC-1 and EC-2
1.4 To choose a basic contradiction and its graphic interpretation. (Usually use EC-1)
1.5 The aggravated (intensified) basic contradiction (e.g. perfectly, totally, completely, etc.)
1.6 Define Problem Model using Intensified Mini Problem:
It is necessary to introduce an X-element that eliminates [any harmful consequence] and enables [the tool to deliver the main function perfectly] with minimal change to the system

2.0 Analyze the Resources
Part 2 focuses on the analysis of the resources that are available such as resources of space, time, substances and fields.
2.1 To define the operating zone (OZ) (the space where there is a conflict)
OZ1: OZ of useful function
OZ2: OZ of the negative function
Identify OZ1 & OZ2 overlapping or not.
2.2 To analyze the operating time (OT)
OT1: OT of useful function
OT2: OT of negative function
Identify OT1 & OT2 overlapping or not
2.3 To analyze resources of substances and fields (SFR)
2.3.1 SFR of the system in the OZ:
Tool/Product -----Substance-----Parameters-----Fields
ID the 3rd component in the conflict situation, if any
Other SFR within OZ (Substance-----Parameters-----Fields)
2.3.2 SFR outside of OZ or Wastes, by-product, secondary resources:
Substance-----Parameters-----Fields

3.0 Define the Ideal Final Result and Formulate the Physical Contradiction
3.1 To define IFR-1 using the following pattern:
X-element eliminates the (harmful action) and allows (to deliver the main function of the system) in the operating space/zone (specify) during the operation time (specify) without compromise*.
[*without compromise – without making the system more complex and without any harmful consequences]
3.2 Formulate the Re-enforce Ideal Final Results with X-element substitute by SFR.
(X-element) itself eliminates the (Harmful action) and allow (Useful Action) in the (Operating Zone) during the (Operating Time) without compromise.
3.3 To define the physical contradiction (PC) on marco-level and micro-level.
The parameter (specify) of the resource (specify) should be value 1 (specify) to eliminate the harmful action (specify) and should be value 2 (specify) to provide the useful function (specify).
Then it needs to identify the Type such as Physical Contradiction (PC); No Conflict (NC) and Irrelevant Parameter (IR).
A: Summary of ID Physical Contradictions
B: Summary of ideas generated from the Non-contractions (NC).

Prof. Sheu said the part 1 to 3 were essence in MATRIZ Level 2 and summarized in the following diagram. Other parts would be studied in MATRIZ Level 3.

Cat. II – Removing the Physical Contradiction
4.0 Resolve the Physical Contradiction
5.0 Apply the Knowledge Base: Effects, Standards (76), and Principles (40).
6.0 Change the Mini-Problem

Cat. III – Analyzing the Solution
7.0 Review the Solution and Analyze Removal of the Physical Contradiction
8.0 Develop Maximum Usage of the Solution
9.0 Review all the Stages in ARIZ in a “Real Time” Application

After Day 3 course, we have dinner with Prof. Sheu in CityU again.

Day 4 (26 May 2015)

Prof. Sheu reviewed the exercise about ARIZ and then introduced S-Curve Analysis for us.

Firstly, Prof. Sheu explained the Trend of S-Curve Evolution. The y-axis of S-Curve is Main Parameter of Value (MPV) and the x-axis is time. MPV is key attribute / outcome of a product / service that is important to the purchase decision process. So the Innovation could be aslo defined as “Significant improvement along at least one MPV”.
1st Stage: The engineering system is “born” when the principle of action is first applied to deliver tis main function.
Transitional Stage: At this stage, the engineering system tries to enter the market which is survival of fitness.
2nd Stage: MPVs improve rapidly and production volume grows. It is a very dynamic stage.
3rd Stage: Engineering system development slows enormously, despite increased efforts.
4th Stage: Engineering system functionality and revenue decline.

After that Prof. Sheu stated S-Curve Analysis (SCA) approach through different TRIZ tools as the following diagram. (Some tools would teach in Level 3 course.)

The “Functional Potential / Cost” Ratio of S-Curve in different stages were discussed. The ratio explained the change of functionality and cost of product in each stage and it used as market strategy.

Finally, the process of SCA was introduced and we would use the following process to examine the stage of Engineering System / Product in its S-Curve.
