Introduction
TRIZ is a thinking process
The way of work
-is solved in a short course
thoroughly and reasonably IDEA Inc. will support all of you
through a development technology centered on TRIZ
so that the Japanese manufacturers candevelop high-quality products fast and cheaply
to enable world-beating product making(From our company profile)
The 9th Japan TRIZ Symposium 2013.9.602

Background- In recent TRIZ symposia, methods of applying effective orsimple TRIZ was proposed by precursory enterprises and study
groups- Since its company formation, IDEA Inc. has been supplying“Working TRIZ” in project consulting at a lot of enterprises-This time, an overview analysis was performed based on theapplications at enterprises where the author directly supported,
and with this result, I will once again propose that “There is noTRIZ that doesn't work” as the milestone of our company’s
10th anniversary- The concrete products, themes and contents for discussionin each enterprise will be described in an abstracted andgeneralized form

'There is no TRIZ that doesn’t work'?
- A topic presented at the IMC User Group Meeting in 2003
before the Japanese TRIZ Society was established- Using TRIZ to create the best product in the world
generating ideas inevitably, not accidentally

1. Produces an increased volume and higher quality･Ideas are exhaustive and to the point･A lot of ideas can be easily generated･A lot of ideas can be shaped into the best concepts
2. Boosts motivation･Strong points of one’s own technology can be recognized･Creative vision will be acquired･The word “impossible” won’t be easily used any more

Problems regarding
the Contradiction Matrix and Inventive Principles- Formation of Technical Contradiction solution matrix• Altshuller investigated about 400,000 patent data all over the world
during 1960-1970, from which he extracted about 40,000 innovative
ones, which he investigated precisely and developed the matrix• The present matrix was completed in 1971 after several revisions- Problems of Technical Contradiction solution matrix• It is considerably difficult and some experience is needed to abstract
real problems as one of the 39 parameters which can be used in theContradiction Matrix• And, even if one gets used to it, as it is not possible to deal with all theproblems with this tool only, it is necessary to cooperate with other toolsof TRIZ
• Therefore, in order to use this effectively, it is desired to simplify theproblem (e.g. clearly define the contradiction) at the former stage*Reference: Theory Edition "Tools of Classical TRIZ" Nikkei Business Publication, Inc.

The Idea of "Solution"- In the beginning was the Problem• There are many kinds of problems which engineers grapple, including
those about quality issues• Will TRIZ offer hints to solve the various kinds of problems? -> YES!
• Is this possible by applying TRIZ only? -> YES & NO!

- The most suitable solution method for the problem
should be applied• Select various tools which TRIZ possess• The optimum solution is efficiently reachedcombining related methods according to yourpurpose

Application to "Problem solving"- What is “Problem solving“• In the product system, when harmful actions such as heatgeneration, noise, vibration, unnecessary radiation, orproblems such as lack of product quality, damage, and theworsening feature to the improvement is clear• Often needs urgent countermeasures, and appears mostfrequently as a TRIZ application theme- Application themes (example)• Vibration control at device drive, radiation sound decrease,prevention of heat generation• Decrease of unnecessary radiation of electric circuit• Trouble measures and yield improvement in the manufacturing
process• Improvement of irregular screen brightness and image flickering• Trouble countermeasures for devices, parts, etc.

Application to "Performance improvement"- What is "Performance improvement"• Ability of basic function (performance) which the productsystem should provide• Processing speed or memory capacity of the personal
computer, display resolution, etc., many of which havecompetitive relation in the market with competitors’ products- Application themes (example)• Image quality improvement of a diagnostic device• Clearness improvement of the photographic image• Speed-up of preprocessing in manufacturing process• Speed-up of chemical reaction• Improvement of radiator cooling capacity• Extending the life span of operation• Improvement of seat product delicacy• Improvement of impurity removal performance in liquid products

Application to “New method identification"- What is “New method identification"• Examination of a form or structure when traditional methods areassumed having reached critical limit or when another function
wants to be added• As observed remarkably in the evolution process of the cellular
phone or car navigation system, it often occurs when newfeatures are taken in• Concept of “[6] Transition to the Super-system” in the Law ofTechnical System Evolution- Application themes (example)• Examination of a new form for accuracy improvement• Examination of a new form for light condensation• A new manufacturing method of multilayer disk
• Improvement of operability of a manual mechanism• Development of a grip method that doesn’t cause internal stress• Identification of a new structure for shortening the lead time

Application to “Cost reduction"- What is “Cost reduction"• In order to secure profit even when facing decrease of themarket price, cost reduction is a pressing issue• Cost reduction through VE is proceeding in a lot ofenterprises, and when using TRIZ, high targets which are
difficult to achieve through a usual approach is often set- Application theme (example)• Examination of methods for cost reduction• Improvement of productivity for cost reduction• Shortening of lead time for cost reduction• Consideration of parts self-manufacture• Cost reduction of manufacturing device• Products cost reduction• Cost reduction of parts peculiar

Application to “Downsizing, Weight reduction"- What is “Downsizing, Weight reduction"• Downsizing and weight reduction is stressed also as aresponse to environmental issues besides the drive to“lighter, more compact,“ some time ago• Besides, it also relates to the law “[7] Transition fromMacro to Micro” of the Technical System Evolution, andleads to the improvement of the function• The approach to the solution is similar to cost reduction- Application theme (example)• Reduction in size and weight of product• Reduction in size of parts• Reduction in size and weight of operating portion• Reduction in size and weight of production equipment• Decrease in product earth floorage• Making the drive assisting part smaller and thinner

Application to "Product planning"- What is "Product planning"• Discovering the user needs, designing and determining
suitable product concepts, and bridging them tocommercialization of products• The usage of the target user should be concretely imagined,and potential customer needs should be probed for in order
to embed features that would exceed the competitors• The key success factor will be the extraction of the"Attractive quality" in Kano's Dual Quality Model- Application theme (example)• Search for product images in the future (** years after)• New value creation of product systems• Usage search for elemental technology
