Abstract:
USIT (Unified Structured Inventive Thinking) is a
methodology and an overall procedure for creative problem solving, originally
developed by Ed Sickafus and then further enhanced by the present author as a
new generation of TRIZ.Usage and training of USIT are demonstrated in the
present paper by example of an actual case of problem solving in a 2-Day USIT
Training Seminar carried out with participants in a multi-company situation.
The problem was to concept a practical system for preventing from our leaving
things behind, such as a bag on a train's shelf, glasses on a restaurant table,
an umbrella at an entrance, etc. The initially-vague problem was to be defined
more clearly in terms of 'the timing of leaving a thing behind'.Then the
situation is analyzed in the USIT scheme of Objects-Attributes-Functions and
Space & Time, and ideal solutions are imagined by use of the USIT Particles
method.On the basis of these analyses various solution ideas are generated and
are composed into a conceptual solution.This example shows the USIT's
capability of handling problems which are initially-vague , related to
software, and oriented to process, etc.
