Abstract
Problem statement: In recent years, much attention has been focused on the eco-efficiency of product development. The majority of environmental decisions are only made in the later stages of product development where not much modification can be done. To produce eco-efficient products, environmental decisions ought to be considered in the early stages of product development. With the demand of developing more eco-efficient products, designers are found to be lacking the appropriate design tools and guidelines. Approach: Products were designed to solve problems. Therefore, we suggest the usage of the 40 principles of TRIZ to generate eco-efficient product designs. The 40 principles of TRIZ is one of the fundamental tools of TRIZ. We studied the design features of different water filters, washing machines and power drills to correlate the elements of eco-efficiency and the principles of TRIZ. Results: From the case studies, it was shown that there is a correlation between eco-efficient elements and TRIZ principles in existing products. The information obtained from the product case studies alongside with the study of the individual TRIZ principles resulted in the formation of a new tool. This new tool was called the TRIZEE Design Tool. After that, literature review on the commonly practiced design methodologies were carried out. A new methodology termed TRIZEE Design Methodology was developed. New tools and existing tools were incorporated within this methodology. Conclusion: We proved that there is a correlation between eco-efficient elements and the 40 principles of TRIZ. Through this research, a new design methodology is also formed to that can be a guideline for designers.
Highlights
In the pursuit of economic prosperity, the environment is left in the state of decline
The approach of applying Ecoefficiency elements and TRIZ principles are integrated with the proposed TRIZEE (TRIZ Eco-efficiency) Design Methodology
TRIZEE design methodology: There are numerous product design methodologies being practiced in the industry
Summary
In the pursuit of economic prosperity, the environment is left in the state of decline. More natural resources are used to sustain such lifestyles and even more irreversible damage is done on the environment. Shortages are ensuing in many parts of the world even in the present time. Such developments are not sustainable due to its lack of eco-efficiency. In order to have a sustainable environment, more eco-efficient products should be designed. One of the main challenges for product designers is the lack of tools to incorporate environmental decisions (McAloone et al, 1998). This research aims to develop a design methodology for ecoefficient products using TRIZ principles
