Examination of Topics of Research

It is more abundant that innovation understands as “Technical improvement”. However, when the valueof GDP (gross domestic product) that matches mining and manufacturing to the construction industry
thinks about the fact of 26.5% of the overall industry (The system of national accounts in 2008: Ministryof Public Management, Home Affairs, Posts and Telecommunications Statistics Bureau), this has the
feeling of the anachronism.
To begin with, the past is an economic terminology in an economic activity in the word innovation
defined to unite by a different method as for the production method, the resource, and manpower, etc.
by Joseph Schumpeter, an economist, in 1911.
According to Drucker, the lead time of Technicalinnovation by invention discovery is long. Reliability
and certainty are low regret most, he said.
Drucker said “To make the innovation succeed,
discovery at chance that exists in industry, external
factor of market, and internal factor, strategy that
effectively uses chance and system of management oforganization that promotes it are required.”
The technology that develops with TRIZ is used as a
new item and service, and the role as the innovation
can be played.

１．What is the final purpose of the system?
→It proposes the lifestyle that achieves the living of senior citizen's ideal.
→A society that can live as the senior citizen laughs energetically is achieved.
２．What is the one that comes out from an ultimate ideal solution?
→Happy life independent of the senior citizen is spent. The senior citizen feels the sense of well-being
and satisfaction.
３．What is it that disturbs the achievement of this ultimate ideal solution?
→It concentrates only on “- is offered to the senior citizen”. Service to the senior citizen is supposed to
shut the road to the contribution to society of the senior citizen.
→It is social system that uses an energetic senior citizen/that not is few.
４．Why does it disturb achievement?
→It is supposed to plunder of senior citizen's independence desire and independent activity time.
→It doesn't become energetic if there is no place that can be active of the senior citizen.
５．How is the one to disturb achievement eliminated?
→An energetic senior citizen positively contributes to the society.
→It thinks about the measure that makes the senior citizen energetic.
（Example：An energetic senior citizen nurses and supports the senior citizens.）
６．What resource can you use to create such a surrounding situation?
→Event（Events, stamp rally, festival, and flea market etc. of every season）
Talent（Retiree and trainee at social welfare school and vicinity resident's volunteers, etc.）→Energies at labor production age to attempt new business creation
７．Can someone else already solve this problem?
→A part of advanced nations（For instance, the Netherlands）, Leaf business of Kamikatsu-cho, 70-years
old active service assistance center in Fukuoka Prefecture, etc.

Here, (1) “Purpose achieved by the solution” is determined by the expectation degree of the new system（ considerably high： 10, high： 8, normal： 6, low： 4, considerably low： 2 ）(2) “Complexity of solution” is determined by the number of components and the number of their relations（ considerably high： 1, high： 2, normal： 3, low： 4, considerably low： 5 ）(3) For “Resource used”, different values are adopted according to the exiting places of resources
and the necessity for changing the resources( system：3, sub-system： 2.5, super-system: 2, surrounding of system： 1.5, derived resource： 1 ）©2014 Intellectual Property Creation Research Subcommittee

Example of Evaluating a Creative Solution
from IBS Software（Ideation International, Inc.）

酸が試料に接触し続ける
容器が酸を保持する【Situation of problem】
To examine the acid resistivity of various alloys, a sample is put into theacid filled in the container.
If you make the testing condition severer by raising the acid density or
lengthening the soaking time, the problem that the acid invades the innerwall of the container while examining is caused.
【Solution example】
1. Coating the inner wall of the container with an acidity-proof material
2. Making the container itself from an acidity-proof material such as glass
3. Making the container from the sample itself( A hole is made in the sample and the acid is put in )【Evaluation of solution】
1. Elegance = (6/3) x 1.5 = 3→ Covering with a protective surface film (external resource)
to prevent invasion is common
2. Elegance = (6/4) x 1.5 = 2.25
→ A secondary problem that the glass container (external
resource) is easily broken will be caused
3. Elegance = (10/1) x 30 = 30 ( full points )→ By solving only with an internal resource, gives birth to a
new value that the container becomes unnecessary酸が容器の壁を侵食する

Judgment comment

Because oil is not used, a healthy deep‐
frying thing that cuts the fatty
ingredient by as much as 80% can be
done. It is possible to cook safely evenby a senior citizen without failure.

Only it is to make the hot windcirculate in the airtight container,
the structure is easy.

Because the enclosed unit and theheat source exist, it only has to
add the cycling mechanism of the
hot wind.

【One‐point for a better one】 Able to cook fry‐ups like tempura, etc., where the ingredients themselves don’t contain oil©2014 Intellectual Property Creation Research Subcommittee
