This paper presents a redesign method supporting sustainable design of products. The method correlates product modularity with various life cycle directions at the conceptual stage of design. In the case of product redesign, the modular design approach allows designers to focus on increasing the sustainability of a product in terms of recyclability, disassembly and reduction of resource usage at the conceptual stage. By stepping back to the conceptual design phase and analyzing the product free from its current embodiment solutions, the scope of redesign and the potential product improvement increases. At this stage of design, the comprehension of the relationship between the various life cycle aspects of the product and the product design is essential. The elimination preference index (EPI) metric, calculated by pair-wise comparison of various factors governing the product design, quantifies the effect of redesign alternatives on product sustainability. The method is applied to the redesign of twelve small-scale consumer products, of which one example is presented here. In all cases, the redesigned products exhibited enhancement in modularity and part count reduction.

Design of adaptable products aims at satisfying different and changing customer requirements through changes of products such as reconfiguration and upgrading during their utilization stages. In this research, a new modular design approach is introduced for modeling and optimization of adaptable products considering the whole product utilization spans. In this work, product descriptions in different operation phases are modeled by different configurations, and each of these configurations is described by parameters. The product components with similar life-cycle properties such as operation phases and life-spans are grouped into modules based on a fuzzy pattern clustering method. A hybrid AND–OR tree is used to model all feasible design solutions considering different configurations and their parameters. The adaptable product is evaluated by different evaluation measures with different units, which are further converted into comparable evaluation indices. The overall evaluation index for an adaptable product is defined by individual evaluation indices and their importance weighting factors considering the whole product utilization span. A multilevel optimization method is employed to identify the best design solution, its configurations in different operation phases and parameter values of the relevant configurations.
