Editor's Note (Toru Nakagawa, Jul. 10, 2009)

This paper was presented at the Fourth TRIZ Symposium in Japan, 2008 , which was held last September by 'Japan TRIZ Society, NPO'.  This is a fine work of building a new software tool which assists the users to input the initial Su-Field Model of the problem and suggests the users possible desirable Su-Field Models along with some examples.  The logic of Inventive Standards is installed in the software..

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.

Computer-aided Problem-solving Assistant for Su-Field Analysis

Abstract

The substance-field analysis with inventive principles is one of the most difficult and less used TRIZ tools although it is reported as among the more likely tools which can generate breakthrough results. The paper established a new coding and su-field based problem solving scheme allowing automatic generation of ISM (Initial Su-field Model) in coded form, intelligent identification of possible corresponding standards, and allowing users to select identified standards and generate solution trigger DSM (Desired Su-field Model) automatically. The system is an Excel-based intelligent problem-solving assistant for su-field analysis. Upon identification of solution triggers, the system will also provide examples to aid human generation of specific solutions given the solution triggers. It will enable a novel user to quickly generate solution triggers without detail knowledge of the su-field knowledge and laborious manual exercise.

D. Daniel Sheu and David Lee (National Tsing Hua University, Taiwan) [O-12 #20] gave an Oral presentation with the title of "Computer-aided Problem-solving Assistant for Su-Field Analysis".  I would like to quote the Authors' Abstract first:

The substance-field analysis with inventive principles is one of the most difficult and less used TRIZ tools although it is reported as among the more likely tools which can generate breakthrough results. The paper established a new coding and su-field based problem solving scheme allowing automatic generation of ISM (Initial Su-field Model) in coded form, intelligent identification of possible corresponding standards, and allowing users to select identified standards and generate solution trigger DSM (Desired Su-field Model) automatically. The system is an Excel-based intelligent problem-solving assistant for su-field analysis. Upon identification of solution triggers, the system will also provide examples to aid human generation of specific solutions given the solution triggers. It will enable a novel user to quickly generate solution triggers without detail knowledge of the su-field knowledge and laborious manual exercise.

The slide shown here summarizes the key issues, current computerizing approaches, and the Authors' contributions (written in red).  The first issue is to set up the Su-Field Model of the problem.  The Authors' approach is to input the meaning of each component in the SF model.  The second issue is to suggest improved Su-Field Models for possible solutions.  This process is carried out automatically in the Authors' new computer software.  The third issue is to help the users think of specific solutions by use of the suggested Su-Field Model.  Authors' new software provides relevant examples for easier reference.

This slide shows how to specify the problem in the Su-Field Model.  The Authors define an array of coding digits, which represents each of S1, S2, Field, Interaction type (of the model), and also restrictions for directing the solutions.  The restrictions are shown in the right table. 

*** This idea of representing a problem in the form of 'Problem Array' seems effective.  However, the users need to understand the questions generated by the software. 

This slide illustrates how the software tool works.  User inputs the problem in the form of the Problem Array (with the help of the Su-Field Diagram), then the software tool uses the logics (such as the ones documented in Victor Fey, Semyon Savransky, or Darrell Mann' books) of deriving Inventive Standards.  The solution part is also coded in the 'Solution Array'. 

The Authors built a software tool by using the ASP.net programming and Access 2003 DB.  An example of program display shown in the slide looks nice. 

*** This presentation is a fine work of making a portion of TRIZ logic available as a software tool.
