Editor's Note (Toru Nakagawa, Jul. 9, 2009)
This paper was presented at the Fourth TRIZ Symposium in Japan, 2008 , which was held last September by 'Japan TRIZ Society, NPO'.
Japan TRIZ Society has posted the presentation files (in Japanese) of all the Contributed Presentations in the 'Members-Only' area of its Official Web site (http://www.triz-japan.org/ ) in PDF on July 1, 2009. Files in English are going to be posted in a similar way.
The present site, "TRIZ Home Page in Japan", on the other hand, is going to post several selected Contributed Presentations publicly, under the desire & permisson by the Authors. Presentation slides of them will be posted in PDF, with the policy of updating prohibited, copying and printing permitted.
This page has the following contents in English and in Japanese:

Among these files, the 'Presentations slides with narrative notes' may be most useful to understand the author's work. The author attached his narration in full detail; the notes exceed the max length for print in a page, and hence the file is posted here in the PowerPoint (in stead of PDF).
Please take a look of the Collection of Papers written by the present Author . 14 Articles written by Toshio Takahara during five years (2003-2007) after his retirement from an IT company are posted, with an introduction by Nakagawa and a bibliograhy by the author.
The General Picture of TRIZ From the Viewpoint of Changing Objects
― A Method of Resolving Differences Based on the Concepts
of Functions and Process Objects Part 3 ―
Toshio Takahara ( )
An important thing is only to make a necessary change on a necessary Object in some necessary way. If we could find minimum types of elements, by the combination of which we could reconstruct the original one in the area of Object and making changes, it could be said to obtain unified method of changing Objects. As a part of this study I investigate the types of changing Objects within two attributes and two Objects.
These studies make clear that TRIZ is an assemblage of changes of Objects consisting of segmentation and merging of attributes, segmentation and merging of Objects and change of attributes including handling “physical contradiction” and “technical contradiction”.
Object has inner structure and attributes which produce function to the outside. From this point of view I classify the existing 40 principles in TRIZ into eight types of principles consisting of basic principles, structure principles, dynamic principles, replace principles, plus principles, minus principles, equal principles and “anti” principles.

 Introduction to the Presentation (by Nakagawa)
Personal Report of The Fourth TRIZ Symposium in Japan, 2008

Toshio Takahara ( ) [O-16 #18] gave an oral presentation with the title of "The General Picture of TRIZ From the Viewpoint of Changing Objects ― A Method of Resolving Differences Based on the Concepts of Functions and Process Objects Part 3―".
The Author, Toshio Takahara, is a retired engineer and a unique self-taught thinker. He has written and presented a series of about 15 papers for these 6 years with a vision to build a general theory which can represent various systems and human activities in a consistent way. It took about 5 years till autumn last year for me to recognize the importance of his works. Last March I dedicated him a section of my Web site "TRIZ Home Page in Japan" to post all his papers. The main page is: "Theory of Resolving Differences" -- A Collection of Papers Written by Toshio Takahara (2003-2007) . I explained his term of 'Resolving Differences' as follows in my Editor's Note:
By the way, the keyword "Resolving Differences" is probably coined by Mr. Takahara. The gap between the reality and what we want or what should be is called the 'Difference'. Recognition of such Differences and trials of resolving or eliminating them are the fundamentals in human activities. Such human activities take various forms and phases, including goal setting, problem recognition, designing, problem solving, etc. In this sense, "Resolving Differences" covers a wider scope than 'Solving problems' and 'Resolving Contradictions' in TRIZ.
The Author feels difficulty in explaining his large-scale theory in a 30 min. talk. I also feels the same difficulty in writing this brief introduction. I am going to show only two figures here:
Takahara's graphical representation is very compact and useful to show the functional relationships between objects. The figure in the right shows that a Person hangs a Picture frame on a Nail with a String. The thick boxes stand for Objects, while the thin boxes represent relevant Attributes related to the Objects. The oval represents a Function; the orange arrows connects the Objects involved in this Function, while black arrows connects the Attributes for showing the change as the result of the Function. This is an example of showing a simple technical system.
The Author wants to apply the same graphical method to the cases of human activities and institution. The figure shown right represents the 'Birth of Commodity and Money' in reference to Karl Marx' "Capital" Chapter 1.
First a Person use a Useful thing for its sake. Then the person finds the thing exchangeable with some other useful things; thus Useful things start to have Exchange-value in addition to their original Use-value. Then the segmentation of Object into Commodity and Money is introduced as a social institution. Commodity has the Use-value, while Money has the Exchange-value.
*** The graphical representation methods by Toshio Takahara are nice entrance to his theory. If you are interested in them, please refer to his original papers in the Collection or in this Symposium. The slides and the full paper will appear in my Web site in near future.
