经典的例子:
目前常用的发明原理有40条,实践证明这些原理对于指导设计人员的发明创造具有重要的作用。当找到确定的发明原理以后,就可以根据这些发明原理来考虑具体的解决方案。应当注意尽可能将找到的原理都用到问题的解决中去,不要拒绝采用任何推荐的原理。假如所有可能的原理都不满足要求,则应该对冲突重新定义并再次求解。
通过下面一个金鱼法的简单应用,让我们来了解一下TRIZ理论中创造性问题分析方法在现实问题解决中的应用。
埃及神话故事中会飞的魔毯曾经引起我们无数遐想,那么现在我们不妨一步步分析一下这个会飞的魔毯。
现实生活中虽然有毯子,但毯子都不会飞的,原因是由于地球引力,毯子具有重量,而毯子比空气重。那么在什么条件下毯子可以飞翔? 我们可以施加向上的力,或者让毯子的重量小于空气的重量,或者希望来自地球的重力不存在。如果我们分析一下毯子及其周围的环境,会发现这样一些可以利用的资源,如空气中的中微子流、空气流、地球磁场、地球重力场、阳光等,而毯子本身也包括其纤维材料,形状、质量等。那么利用这些资源可以找到一些让毯子飞起来的办法,比如毯子的纤维与中微子相互作用可使毯子飞翔,在毯子上安装提供反向作用力的发动机,毯子在没有来自地球重力的宇宙空间,毯子由于下面的压力增加而悬在空中(气垫毯),利用磁悬浮原理,或者毯子比空气轻。这些办法有的比较现实,但有的仍然看似不可能,比如毯子即使很轻,但也比空气重,对这一点我们还可以继续分析。比如毯子之所以重是因为其材料比空气重,解决的办法就是采用比空气轻的材料制作毯子,或者毯子象空中的尘埃微粒一样大小,等等。
通过上面一个简单分析过程,我们会发现,神话传说中会飞的毯子逐渐走向现实,从中或许我们可以得到很多有趣甚至十分有用的创意。这个简单的应用展示了金鱼法的创造性问题分析原理:即它首先从幻想式构想中分离出现实部分,对于不现实部分,通过引入其它资源,一些想法由不现实变为现实,然后继续对不现实部分进行分析,直到全部变为现实。因此通过这种反复迭代的办法,常常会给看似不可能的问题带来一种现实的解决方案。
金鱼法源自俄罗斯普希金的童话故事:金鱼与渔夫
故事中描述了渔夫的愿望通过金鱼变成了现实
映射金鱼法中,让幻想部分变为现实的寓意。
Classic example:
At present commonly used invention principle has 40, the creation that practice proves to these principles design staff to guidance has main effect. After should finding affirmatory invention principle, can consider specific solution according to these invention principles. The principle that ought to notice to will be found as far as possible is used in the settlement of the problem, do not reject the principle that uses any commendation. If all likely principles do not satisfy a requirement, should seek solution again to conflict redefine.
Pass below the simple application of law of a goldfish, problem of the creativity in letting us understand TRIZ theory analyses a method to solve medium application in real problem.
Demon blanket once caused the volant in Egypt fairy tale we countless daydream, so we might as well now analyse blanket of this volant demon step by step.
In real life although have a rug, but the rug won't fly, as a result of,the reason is earthly gravitation, the rug has weight, and the rug is heavier than air. In the rug below what condition can you fly so? We can bring to bear on up force, the weight that perhaps lets a rug is less than airy weight, perhaps hope the gravity that comes from the earth is nonexistent. If we analyse rug and the environment all round its, can discover such a few resource that can use, if the neutrino in air flows, field of gravity of magnetic field of empty air current, earth, earth, sunshine, and rug itself also includes its fiber material, appearance, quality. So use these resource to be able to find a few way that allow a rug to fly, for instance the fiber of the rug and neutrino interaction can make the rug flies, on the rug installation offers the engine of retrorse active force, the rug is in the astrospace that did not come from earthly gravity, because the pressure below increases and the rug is hanged in sky (air cushion blanket) , use principle of magnetism in suspension, or the rug is lighter than air. These method some are actualer, but some still looks be like impossible, for instance although the rug is very light, but heavier than air also, to this we still can continue to analyse. Because its stuff is heavier than air,for instance the rug is again, settlement way uses lighter than air material to make a rug namely, or the rug is as atomic as aerial dust same size, etc.
Pass above process of a simple analysis, we can discover, rug of the volant in mythological fokelore moves toward reality gradually, from which probably we can get a lot of interesting very useful even originality. This simple application revealed the creativity problem of goldfish law to analyse a principle: Namely it gives actual share from the depart in imagining type conception above all, to not actual share, through introducing other resource, a few idea by not actual turn into reality, continue to undertake an analysis to not actual share next, until turn into entirely reality. Relapse through this kind accordingly the method of iteration, often can give see the solution that seems impossible problem bring a kind of reality.
Goldfish law comes from the fairy tale story of Russia Pu Xijin: Goldfish and fisher
The desire that fisher described in the story became reality through goldfish
In map goldfish law, let imagine a part to turn into real message.
