1. Investigative Purpose
What is an invention development work?

31. Investigative Purpose
Invention derived by invention development work?

41. Investigative Purpose
Technique and the problem in the past.

Purpose of invention development work
･A high-ranking invention, the horizontal invention, and the subordinate
position invention are derived from the inventor's invention.
⇒A technical range of the invention is enhanced, and the patent of theinvention is improved.
⇒The prior patenting of the cooperation other companies is evaded.

Technique in the past･It executes it by the brainstorm (Brest) by parties concerned.

Problem of technique in the past
･General problem of Brest:
5-Efficiency is low.
-It is not possible to slip out the stereotype.

1. Investigative Purpose
Solution rough draft of problem of technique in the past

Rough draft that solves problem of techniquein the past･Invention development work using TRIZ

Advantage of TRIZ
･Stereotype breaking down when technical idea is created･Efficiency improvement of technical idea creation

Advantage forecast by using TRIZ
･Invention development work ⇒ stereotype breaking down +efficiency improvement61. Investigative Purpose
Problem of TRIZ use

Difference of assumption･The invention development work starts from the state of the invention
creation ending.
･TRIZ starts from the state of the invention uncreation.

Relation to condition for patentability･The patent of purpose = invention of the invention development work isimproved.
･On patent inclination of invention and early patent evasion of the cooperation
other companies⇒Condition for patentability consideration main point･As for TRIZ, the relation to the condition for patentability is not considered.
⇒It is difficult to apply TRIZ to the invention development work directly.

Condition for patentability

NameOutline

Novelty

It should not be an invention (hereafter, invalidating art) etc.
known to an unspecified person in Japan or the foreign country
before the invention that demands making to the right applies
for the patent.

Progres It should not be the one that was able to be invented easily
before the person where the invention that demands making tosivity
the right has usual knowledge in the field to which the invention
belongs applies for the patent based on the invalidating art.

Single9It must be a technical feature in the invalidating art without,and there be a common technical feature for the invention ofthese two or more when the invention of two or more has been
described to one patent application.

Invention A

Technical field･Hull construction of hydraulic power
unit that generates electricity in river

Background art･The screw is arranged between a pairof floatage bodies.

Technical problem･The screw rotation speed changes
along with the volume of water change
and the power generation efficiency is
not steady.

Invention A

The first invention･Hydraulic power unit assumed to be able toassume that floatage body can betransformed in proportion to hydraulicpressure, and to adjust interval between
floatage body and screw･Concrete structure to assume that it ispossible to transform it= A part of the floatage body was assumed
to be a slide structure, the slide part wassupported with the spring, and it wasassumed the structure to do the slide to theposition in which hydraulic pressure and the20elastomeric force balanced.

The horizontal invention derived in Brest･Hydraulic power unit assumed to be able toassume that floatage body can betransformed in proportion to hydraulicpressure, and to adjust interval between
floatage body and screw･Concrete structure to assume that it ispossible to transform it= A part of the floatage body was assumed
to be a link structure, and it was assumed thestructure that the manual operation was able
to move at the link position.

45. Summary and problem in the future
Summary･It was able to propose the deriving technique of the horizontal invention that applied TRIZ.
･Efficiency improvement and breaking down the stereotype became possible compared withBrest because it applied TRIZ.
･The number of horizontal inventions can be increased, and on the patent inclination and thetechnical range enhancing can be expected.
･Because the invention derived by the horizontal subprinciple is characterized in the firstinvention and a common invention principle, it is easy to fulfill the single in the condition forpatentability.
･In the evasion of the early invention principle and the early invention subprinciple, the early
patent evasion is easy.

Problem

28･Because two or more invention principles are combined and the first invention is derived, thetechnique that can be applied for this case is examined.
･There are a lot of examination problems of the method of evading the early patent because it
is not invention principle = composition requirement.
･The development technique of a subordinate position invention and a high-ranking invention
is examined.
･Relativity with conditions for patentability other than the single is examined.
