In working with a group, it is important for the facilitator to make the point that the best solution can only be obtained by making sure that all solutions have been considered. Management can reinforce the point that committing millions of dollars to new projects can only be done in confidence when all options have been considered.
Even if the organization cannot afford or chooses not to pursue all directions, patent claims can be filed which may result in licensing revenue. The handling of large idea lists can also he enhanced by sharing the evaluation task among several individuals and groups. This not only spreads the workload, but also provides the opportunity to obtain divergent idea inputs.
Directions relating to this area are in statements in figure 2. In summary, we must consider a large number of external factors and issues when deciding how to approach different kinds of customers with out TRIZ tools.
Tailoring our approach and how we use our various tools can be the key to successful implementation and sale of TRIZ software and consulting.

Based on these acknowledgements a flow chart of Intuitive Design Method building will be presented. Then, a case study will support our approach. This case study has been conducted in M. Coutier one of the French automotive supplier leader and the presented product will be an intake manifold. Both these theoretical and practical approaches will lead us to a conclusion that demonstrate the usefulness of the IDM model, and that there is no metamethod that can be apply to any company, but a dynamic set of existing basic rules.
These rules have to be formalized in order to significantly increase engineers abilities to conduct and to optimize a total design process. In the face of competition, the ever more rapid emergence of new products, changing consumer fashions and globalisation, they are forced to call into question the efficiency of their design methods to keep their competitive edge and ensure their survival.
Within this very general frame, work on design methods has always tended to foster one or other dimension of the process, which isolates the notion of need from the industrialized product. Moreover, in almost all books and international publications presenting the most advanced work on design, key references are credited to the 3 major economic and industrial centers, i.
And yet, geographically speaking, the scope of knowledge on Earth is not limited to these 3 major centers. Fundamental importance must logically be awarded to the former Soviet Union in fields belonging to the so-called pure sciences mathematics, physics, chemistry etc. During our research, we have had contacts with some of these countries on several occasions Russia, Belarus, Ukraine, Azerbaijan and Moldavia etc.
We also realized that they were going to help provide us with answers. An acceptable model of the design process, based on an analysis of several contacts with the academic and industrial world, must meet a large number of requirements [Nordlund ]. To establish this type of model, a survey of existing design methods was conducted. Choices concerning the selection made for the rest of this thesis result from an analysis of what exists in the industrial and academic fields on the subject of design.
Research and Practice on the Theory of Inventive Problem Solving (TRIZ)
After analyzing the various design methods, our initial reaction was that confusion reigns as to what they can offer the designer. Indeed, while they all advocate that they can act as a reference in terms of how a design project should be conducted, they rarely make allusions to what could be perceived as complementarity between them.
This state of affairs often leads to redundancy in terms of the answers they provide for the designer. If we adopt an abstract dimension for the methods studied, the various representations of the development process provide us with a common vision centered on 4 essential phases1: data collection and analysis Collect ; creation Create ; construction Construct ; and growth ProduCe.
Since they are highly generic, they provide a structural approach to the project and in no way consist of a rigid, fixed structure. We should remember that no method takes the methodological history of the company into account.
Their structure is fixed in relation to this and any company that operates one method or another or sometimes merely rules is therefore obliged either to train themselves regarding the new method they wish to adopt, or to adapt it to what already exists in their company by acting intuitively in terms of its integration. Backed by this statement of fact, our analysis is therefore based on a prior survey of what exists on a methodological level. This survey is then used in a logical fashion to build up the integration strategy best suited to the company.
Our conclusion is that ideally, the designer should be able to increase the relevance of his project with a minimum number of changes to his design habits. In order to do this, we offer to draw up a survey of the strong points of each method with the aim of detecting any deficiencies in terms of relevance in the project and to bridge these deficiencies, not by integrating a method wholesale, but by integrating its strong points alone.
Once the state of the art of the strong points in design methods has been formalized and since the methodological and technical knowledge of the company is a known factor, it becomes possible to deduce which intuitive design method may be most appropriate for a given company.
Furthermore, this document must be designed so that it can be drawn up rapidly and it must be easy to use. The findings of this type of analysis should provide the final choice of strong points in each method for each stage of the project.
Indeed, its relevance and operational profile are fundamentally different from those of other methods studied.
This is particularly true for the creativity phase which, although its is barely relevant in other methods, is the strong point of TRIZ, since the methodological effort of a company wishing to improve its design process will no doubt occur with TRIZ. The fact that training programs for some of them are virtually nonexistent in engineering courses adds to the fact that the learning process presents a difficulty for the industrialist.
The financial aspect obviously presents a difficulty and a major obstacle to the integration of the new method. The economic context merely accentuates this difficulty since it is not easy, on first contact with a new method, to grasp the return on investment in man-hours that it will generate.
It would seem logical that the ideal combination would consist in collecting and analyzing data with QFD, generating concepts with TRIZ and ensuring the optimization of parameters with Robust Design [Verduyn ]. Yet this combination is only ideal from a theoretical point of view. A whole panoply of difficulties awaits designers who wish to combine these methods. The object of this formalization is to offer the company a strategic choice in its decisions regarding the orientation of its design method.
The stages and generation of the intuitive design method Since the state of the art of the strong points in design methods has been formalized and the methodological and technical knowledge of the company is a known factor, it is now possible, according to the following graph figure 2 to deduce which intuitive design method may be the most appropriate for a given company.
It was conducted at the company MGI Coutier an automobile parts manufacturer. The project selected as the presentation medium was the intake manifold. The intake manifold is an important element in the gas inlet zone of the cylinders. Its shape and the lack of space available under the bonnet mean that today, it is an element which has undergone little optimization in terms of its structure and shape.
With the aim of improving its performance in use, the intuitive design method developed in our research project has been applied to generate innovative concepts which may solve the major problem related to its shape. This research center employs some 40 engineers and 20 technicians and is in charge of research on new products and systems.
The notion of novelty lies in the aptitude of development centers to conduct a study independent of the research center re-looking, minor developments etc. Upstream studies requiring the backing of research materials, process, technology, innovation etc.
It should be noted that development centers may deal with a study independently while, in terms of resources, calling solely on the computational center simulations, flow, analyses etc. A training course lasting 5 days has therefore been set up to reach this target. In this framework, some notions of robust design are put forward in a second training course lasting 5 days. This second point is nonetheless more complex to grasp since the development units which need to be associated with the process are numerous and therefore investment is high.
We will nonetheless put it to MGI that a specialist in Robust Design should be trained in an attempt to transfer part of the knowledge acquired to future actors in the design phase.
Initially, the different phases were formalized. The aim was to apply all the tools best adapted to the project. The problem posed presented a need for largescale development.
Particular effort will therefore be focused on the phases upstream to the design stage so that the utmost may be done to ensure that the ensuing concepts are innovative. The drawback here is that the ensuing concepts will probably require research in the medium term. Figure 5 gives a summary of these steps and the expected objectives. If the volume of the plenum chamber is altered, the results are low and may even be slightly negative.
This analysis demonstrates the full relevance of correlation between the creation phase and the construction phase. The iterations required between these two phases lead us to state that the proximity of the design and computational centers and the multidiscipline approach of the different actors in the design phases largely contribute to the notion of total design.
We were therefore able to see that this new concept could help develop a divider where the length of the pipes is easily adjustable. Furthermore, another advantage in this divider is that the swirl effect is fully utilized inside the plenum chamber, if the distribution of the pipes is correctly arranged. Wave was unable to modelize this phenomenon code 1D. Simulation using Fluent fluid mechanics code in non-stationary 3D should enable this idea to be validated.
TRIZ: THE RIGHT SOLUTION AT THE RIGHT TIME: A Guide to Innovative Problem Solving
This is probably due to the fact that courses in engineering schools for industrial sectors have little room for physics and chemistry etc. The result is that company engineers turn away from these resources and adopt design routines which revolve around the knowledge acquired in their specific discipline alone.
Reducing mechanical systems to simple principles of physics can, however contribute significantly to the development of the design activity [Souchkov ].
Creativity too is often left by the wayside when companies make choices in terms of investments to increase their competence in design.
The metamethod, so sought after in research, probably does not exist. The effort to build up competence thus defined must not only have a bearing on the deficiencies detected in the company.
This detection work must be independent from any sectorial polarity since reality is often interpreted differently by each of the actors involved. The purpose behind this dynamic method is to increase the efficiency of design in a given company, and a fresh application will be required for each new company. Zlotin, A.
Lutz, P. From this he developed a set of 40 inventive principles and later a matrix of contradictions. Columns refer to typical undesired results.
Each matrix cell points to principles that have been most frequently used in patents in order to resolve the contradiction. For instance, Dolgashev mentions the following contradiction: increasing accuracy of measurement of machined balls while avoiding the use of expensive microscopes and elaborate control equipment. The matrix cell in row "accuracy of measurement" and column "complexity of control" points to several principles, among them the Copying Principle, which states, "Use a simple and inexpensive optical copy with a suitable scale instead of an object that is complex, expensive, fragile or inconvenient to operate.
A screen with a grid might provide the required measurement. As mentioned above, Altshuller abandoned this method of defining and solving "technical" contradictions in the mid s and instead used SuField modeling and the 76 inventive standards and a number of other tools included in the algorithm for solving inventive problems, ARIZ.
Laws of technical system evolution[ edit ] Main article: Laws of technical systems evolution Altshuller also studied the way technical systems have been developed and improved over time. From this, he discovered several trends so called Laws of Technical Systems Evolution that help engineers predict the most likely improvements that can be made to a given product.
The most important of these laws involves the ideality of a system. Substance-field analysis[ edit ] One more technique that is frequently used by inventors involves the analysis of substances, fields and other resources that are currently not being used and that can be found within the system or nearby. TRIZ uses non-standard definitions for substances and fields. Altshuller developed methods to analyze resources; several of his invention principles involve the use of different substances and fields that help resolve contradictions and increase ideality of a technical system.
For instance, videotext systems used television signals to transfer data, by taking advantage of the small time segments between TV frames in the signals. SuField analysis produces a structural model of the initial technological system, exposes its characteristics, and with the help of special laws, transforms the model of the problem.Chapter 7: Karen is long married, has four children and three grandchildren lives happily in Oxford and the Lake District.
Imagine that all inventors become good salespeople, have the support of management, and have excellent presentation skills and materials. Without a theory, people generate ideas by guesswork and then select the ones they like or those they think other people will like.
Find a way to eliminate, reduce or prevent [the] TRIZ is rejected. Reducing mechanical systems to simple principles of physics can, however contribute significantly to the development of the design activity [Souchkov ]. Providing a group the opportunity to share organizational experiences with solving poorly defined problems can also help this process. Altshuller developed methods to analyze resources; several of his invention principles involve the use of different substances and fields that help resolve contradictions and increase ideality of a technical system.
