From Idea creation to a Patent acquisition by TRIZ－For the escaping from danger livingry of the victim of the disaster－TOSHIM ITSU KATAOKA * (PATBRAIN Co.,LTD )YUJI MIHARA(CREATIVE TECNOLOGY INSTITUTE Co.,LTD )We challenged the making of example with the universality to be usable as a TRIZ
example for activity of the Knowledge Creation Study Group, Mitsubishi ResearchInstitute. Afterwards, we challenged not only making of example as the study, but also
the patent acquisition.

The setting of the problem
Whenever natural disaster such as a big earthquake
or a typhoon happens, we are in condition a large
number of people to have been packed into the large
places such as gymnasia, and it is put and we are in
condition to have only blue seats to us to the utmost
and are forced to live a life.
We improve this living environment in the gymnasium of
the victim a little.

Divide a hard board into aplural number and tie up athin board with a hinge

Affix it with a thin film (re-enforcedfilm).

The mini-sample

Because we flatten it and can use it as building department materials such as
inner wall materials or floorings such as gymnasia in normal, we can use it even if
we do not prepare for a large safekeeping place and storage space separately. If
we tear it off from a wall surface and the floor and move it at the time of thedisaster outbreak such as an earthquake, eruption and the flood on the floors
Conscioussuch as gymnasia
and ofweTRIZ.
start it and spread cushioning side on the surface on aSuccessfloor, we canuse it wonderful
as a comfortable cushion though we lie and sleep. If we add
by a contradiction
legs and assemble
it as a chair, we can use it as a chair with the cushion and canappeal！
avoid painsolution
for a person
hurting a knee and a waist.
And, we can use it as a dining table at the time of the meal and a table by athing of work as a table top if we make the hardness side the top surface
because the top surface becomes flat.
We can used as a parting strip or wall by using hardness parts . Furthermore,
there is soundproof effect by the cushion materials and we can protect privacy
from neighboring people more or less . We can use it as a structure body serving
as the many functions that had hardness and the softness while being one
structure materials. We relax pain of refuge life frightened by uneasiness more or lessand can send comfortable refuge life conventionally.

This invention became the Patent.
Our claim that used TRIZ was accepted．
