The １１th Japan TRIZ Symposium 2015.9.4 I will introduce the approach of the product development to make good use of TRIZ, Taguchi method, and CAE in the technical field 'All-Japan manufacturing Koma great war' that was newly born.

In Intr troductio tion

How do you approach in the technical field without the current experience when it will be necessary to develop the product with high competitive edge in a short term?

What at is is th the all all-Jap apan an man manufac factu turin ring Koma ma gre reat at war? war? ■What is the Koma great war?

It is a rally (bringing together Koma that small and medium manufacturers in the whole country are bet the boast of its company and made, and the fight by the one to one). Manufacturing seriously designs small Koma, and everything is poured and the technology that its company can have with a professional machine is made. A professional technique is fatty soaked of the ring on each other.

■What rule?

Having kept turning longer than other party's Koma wins. It is defeated besides the ring when going out. Game end at two successive victories The victor can get loser's Koma. (It is a content total removing of booty till then. )

Problem definition from function model

11

【Definition of problem】

An adverse effect, a lack action, and an excessive action are extracted, and the minimum problem is defined.

①How is the function that the axis slips in the finger removed? ②How does the finger strengthen the rotation of the axis? ③How is the function that the axis raises center of gravity removed? ④How is the function that the angle of bank raises center of gravity removed? ⑤How is the function that the solid of revolution raises center of gravity removed? ⑥How is the function that mass improves the frictional drag removed? ⑦How is the function that the wick blur improves the frictional drag removed? ⑧How is the function that the wind drag weakens the rotation energy removed? ⑨How is the function that the other party Koma weakens the rotation energy removed? ⑩How is the function that the frictional drag weakens the rotation energy removed? ⑪How is the function that the angle rate invents the wind drag removed? ⑫How is the function that the other party Koma invents the inclination of the axis removed? ⑬How does the inclination of the axis remove the function that the ring comes in contact? ⑭How is the function for center of gravity to enlarge the inclination of the axis removed? ⑮How does the finger strengthen the maintenance of the axis?

【Definition of technical contradiction】

It pays attention to the adverse effect, and it looks for technical contradiction from the relation between a component and a useful action that generates it.

①The improvement: To make the axis easy to have, it lengthens it. Deterioration: Center of gravity rises. ②The improvement: To enlarge the moment, the solid of revolution is made heavy. Deterioration: Center of gravity rises. ③The improvement: To enlarge the moment, the solid of revolution is made heavy. Deterioration: The frictional drag grows. ④The improvement: To enlarge the inclination of the axis, the angle of bank is enlarged. Deterioration: Center of gravity rises.

【Definition of physical contradiction】

The physical contradiction of the component with an opposite characteristic is defined by technical contradiction. ①It is necessary to shorten it to lower center of gravity though it is necessary to lengthen the axis to make easily to have. ②It is necessary to reduce it to lower center of gravity though it is necessary to enlarge the angle of bank to enlarge the inclination of the axis. ③It is necessary to lighten it to lower center of gravity though the solid of revolution should be made heavy to enlarge the moment. ④It is necessary to lighten it to reduce the frictional drag though the solid of revolution should be made heavy to enlarge the moment.

Problem definition from primary cause

12

【Specific of primary cause】

The factor that we can control is assumed to be a primary cause among factors that the arrow doesn't enter. (yellow, in figure blue factor)

【Definition of pivotal question】

The problem (contact and make a careless pitch with the other party) not brought up from function-attribute analysis is extracted as a pivotal question to be treated this time among the primary causes. (factor blue in figure)

【Contact factor with other party】

①It comes in contact with the other party in outer. ･The method of no contact with other party? ･Do to come in contact in places other than outer? ②The frictional drag is caused by contact with the other party. ･The method of absorbing other party's energy? ･The method not to cause friction even if coming in contact? ③It is lighter than the other party. ･The method of no flight even if it is light? ④When coming in contact, a transverse impact is received. ･The structure to let impact go? *Paradoxical, the problem to win is defined.

【Make a careless pitch factor】

①The nose geometry is flat. ②It strains oneself. ③It doesn't have the switch easily (The axis inclines when turning it on).

【Others】

①The method of attacking axis and stability of other party? ②The method of increasing other party's frictional drag? ③The method of inviting the other party pitcher's make a careless pitch?

19 Bearing (flange type) Solid of revolution The bearing tire (flange part) comes in contact earlier than the lower side of the solid of revolution when the rotation decreases, and the axis inclines with rings. As a result, a rapid decrease in the turning force because of friction with the ring is prevented, and it stands dominant when having a close game. Steel ball Ring It absorbs by rotating the flange part even in case of the make a careless pitch with the axis inclined and it recovers.
