The use of the life cycle in the design of environmentally friendly products is common. However, this tool requires a lot of data, time and expertise. If it is today recognized that a lot of implementation and evaluation of impact software exists, it is however very often expensive to collect all the many data in cases containing relatively large margins of error and difficult to collect. All these difficulties have forced several businesses, especially those who do not have financial means, not to use the tool at this level of expertise.

Constraint can be lifted by using more simplified tools requiring less data, in general of a recommendation nature, and the outcome which is in this case qualitative remains approximate and will serve as overall direction for the designer.

We have adopted an approach that consists in proposing a qualitative evaluation matrix including no less important parameters related to the comfort factors of the product and organizational preparation for the appropriation of an eco-design approach, in addition to the standard factors of eco-efficiency. The operation will determine the environmental profile of a product. In order to help the designer to make a decision, the TRIZ (theory of inventive problem solving) method is proposed. This way of proceeding can help the designer and encourage the company to choose an approach and attain a degree of eco-design at the level of the resources available to it.

Proposal for a simplified assessment process

The environmental effects of the design of a product all throughout its life cycle can be evaluated by use of a matrix that is based on a written response to questions that have been put together in a sufficiently general manner to apply to a wider range of products.

It is a square matrix (5×5) which encompasses vertically the stages of the life cycle of the product (prefabrication, manufacturing, transportation and packaging, use, end of life) and horizontally the sources of environmental impacts. Each element of the matrix is presented as a score (from 0 to 5, with 5 being the best location, perfect for reducing impact). This assessment can be made after the answer given to each question in the box. The first line of the matrix is in the form of an inquiry in relation to organizational situations of the company with respect to environmental issues.

The results of the prioritization of environmental issues will be expressed as a histogram on a scale of 0 to 5. This hierarchy corresponds with the environmental assessment of the product.

Here, the TRIZ contradiction matrix method is proposed. TRIZ consists of various tools, including the popular contradiction matrix module that consists of the contradiction matrix and invention principles [1].

The method is based on the exploitation of the matrix, on the guidelines selected, the 39 design parameters and the 40 inventive TRIZ principles.

According to the prioritization of environmental issues made as in figure 2, the designer will make the choice of the most relevant eco-efficiency parameters, consistent with the frequency of occurrence of each parameter. The choice of the corresponding inventive principles will be made from the engineering parameters. The following table gives the relationship between the elements of eco-efficiency and the parameters chosen in relation to the elements of the TRIZ matrix (table 1).

Conclusion

The idea of exploiting the results of the qualitative evaluation matrix taking into account the life cycle of the product and, in the case of a multi-criteria analysis, can provide us information on the most relevant eco-efficiency factors which will serve as an important benchmark to complete the study and then direct the user towards a design that respects the environment. In order to solve the problems of allocation of impact factors with respect to the eco-efficiency parameters and the resulting contradictions, we have applied the TRIZ method.

This method is often wrongly considered as a tool to invent new concepts. However, in our case, this tool was used to help the designer to choose among the cases of principles or ideas that best fit the design problem that presents itself to him. The idea of replacing the parameters of contradiction with parameters of eco-efficiency is an approach justified by the analogy that may arise from the numerous contradictions of environmental factors. Thus, the TRIZ-matrix method can be tested. It will, in many cases, allow to trigger a reflection on alternative solutions in situations of conflict, particularly unresolved situations and situations that are beyond the company’s framework.

Moreover, it is worth noting that this tool which was developed to be a solving approach cannot explain some design problems which are only determined by a thorough and detailed analysis.
