Inventive problems are accompanied by phrases such as : “It can’t be done,” “It is physically impossible,” and the old engineering and scientific standby : “it is against the laws of physics.”. Inventive opportunities are all around us; it is only a matter of learning how to see them. This, coupled with a systematic approach to resolve inventive problems, literally changes the way we think about problems.
If we reduce psychological inertia and therefore have a greater opportunity to find a better solution. model requires completion and offers directions for innovative thinking. Psychological inertia is the tendency that humans have to move in a direction of comfort and security. This is not always the direction of the best solution
Concept of ideality is "Think of the end before the beginning". By defining and attacking the envisioned ‘Ideal Final Result(IFR)’ , we enable to choose the most promising direction Ideality is represented by a vector with the area in proximity to the vector representing the area of high level solutions.
The ideal solution for a company is the one that takes into consideration the availability of resources and local(company) limitations. If the solution is toward the minimization of cost factors, then that will have the higher local(company) ideality. Application of technological system’s resources is one of the primary ways of increasing a system’s ideality.
One example is introduced in the following section. We have to Evaluate the degradation of a specimen exposed to a strong acid over a long time. In testing, the specimen in the container is also degrading that will affect the accuracy of the test. The typical solution is adding protective coating, but it requires a delay in time and adds cost. We need a simpler solution.
An ideal solution is One that does not involve require a container, and the solution should be implemented with the most basic of tools.
The specimen is modified so that it is the container.
This solution meets the local ideality requirement by being easy to implement, as easy as drilling a hole, and by avoiding the time delays and cost associated with replacement of the container or coating.
There are two ways to approach new innovative designs. Find the tools, mechanisms and devices to make it work ( create a more complicated system) Deny introduction of new tools mechanisms and devices ( create a simple, more ideal system). Desirable Objective of defining and pursuing ideality is achieving long-term benefits as a result of visualization of the optimum solution. The more original a discovery, the more obvious it seems afterward.
A situation in which a characteristic of a system must exist in two states. This situation is a subset of a technical contradiction. Physical contradiction is located on the ideal final result vector. Physical contradiction must be in two opposing states. No compromise or trade-off is allowed. To convert from a technical contradiction to a physical contradiction, you must determine what characteristic is controlling the technical contradiction condition.
There are 39 technological contradictions, and 40 Typical Techniques is used for Overcoming those contradictions. It contains attributes that are the most common for all technological system. These attributes are arranged in rows and columns. Suppose there is a need to improve some attribute of the system. If this improvements causes deterioration of another attribute, an intersection of the row and column corresponding to the conflicting attributes will show the useful principles.
A technological system involve at least three components: a tool, an article, and an energy source. These components are described in TRIZ in terms of substances and fields. Substance is a technological system of a various degree of complexity, for instance, nail, keyboard, or ship. Field is Energy needed for interaction, for example, mechanical, thermal, electromagnetic, and chemical force and so on. The following is an example of solving problem using Su-Field analysis.
