“…Among the several methods for Ecodesign, those particularly interesting for this paper propose integrations with theories of inventive problem-solving, and in particular with TRIZ. [19] and [20] affirm that TRIZ can help the designers in overcoming some critical issues during Eco-product development by means of potential innovative solutions, or even before, according to [21], by supporting the Anticipatory Failure Determination. [22] instead states that TRIZ integration is valuable since it does not require an encyclopedic knowledge of field-specific technology and it enables the expansion of the scope of problem solutions beyond the skills of the team members.…”

This paper proposes a set of Eco-guidelines for supporting designers in developing new greener products and processes. The first requirement that a guideline should have is to be sufficiently general to cover every kind of problem and at the same time sufficiently specific to bring the user closer to the solution without requiring too much personal inspiration. This balance was searched by adopting one of the most known systematic innovation techniques: TRIZ (Russian acronym of Theory of Inventive Problem Solving). In the literature, there are many examples of integrations between Eco-guidelines and problem-solving methods, but the solutions that are suggested, however effective, are not necessarily eco-friendly. To overcome this problem, the authors propose a rigorous ontology indicating how to apply a specific problem-solving strategy onto a specific part of the problem, trying to make the user aware of the environmental consequences of his design changes. The result of this work is a set of 59 guidelines. The article explains the birth of each guideline, the way in which they were adapted with respect to the known technique, and the motivation for which they should generate greener solutions, in light of the results of an experiment involving engineering students in real industrial cases.

Quality Function Deployment (QFD) is a quality management tool that transmits customer requirements into product design or innovation process to improve products' customer satisfaction. For the first time, this paper points out the distortions of customer requirements existing in the transmission process of QFD that are caused by the methods for calculating the importance degree of output information. The distortions lead to the designed or innovated product meeting less important customer requirements, without meeting more important customer requirements, so products' customer satisfactions are decreased. In order to avoid the distortions, a new method for calculating the importance degree of output information is proposed and an example is illustrated to demonstrate the effectiveness and superiority of the new method.

Abstract. The Musculoskeletal disorder (MSDs) is skeletal muscle disorders that lead to damage in nerves, muscles, joints and cartilages. The damage is caused by muscle tension and degeneration. From the preliminary research in virgin coconut oil (VCO) processing industry, Central Java, Indonesia, there are potential risk of MSDs for workers. The majority of operators complaining on the right thigh (score 37) and left thigh (score 35). In addition, 50% of operators is work with moderate risk (rapid entire body assessment scores 4-7) and 50% others at a high risk level (rapid entire body assessment scores 8-10). Therefore, improvement is needed to prevent MSDs through work facility design using an integrated quality function deployment (QFD) method. In QFD, there is a concept screening phase to select some product design concept. To determine the priority, the QFD method can be integrated with analytic hierarchy process (AHP) method. The research shows that attributes of work facility needed by user are ergonomic, portable, durable and aesthetic. Concept design B have the highest priority score 0,32 and selected as the final work facility design. The technical specification are made from mahogany wood with an attractive design, red colour combination and developed based on user's anthropometry data.
