Modular Product

As technology pushes customers to buy new released products, especially mobile phone, high product replacement from the customers plays a role in increasing production rate for new products and rate of abandoned products. It accelerates environmental degradation like natural resource usage for the new products and pollutions generated by disposing the abandoned products. In this respect, product recovery is needed to reduce landfill rates, and resource usages, and prolong product lifecycle. Modular drivers such as interface design, material type, and components’ lifespan are applied to design modules for product recovery. The objective of this research is to support designers to assess initial modules and then reorganize modules for product recovery. First, according to conventional modular product design, the initial modules are generated. Then, since it is difficult to estimate how much the modules have negative effects on environment, the environmental impacts of a product are assessed by Eco-Indicator 99 based on used materials. Also, the complexity of the interface design is measured to understand how the modules are easily disassembled for upgrading and maintaining end-of-life products by using weighted-modular complexity score (wMCS). After assessing the product based on the Eco-Indicator 99 and wMCS, we apply new design guidelines to improve sustainability of a product in the end of life stage. Consequently, we compare the extent to design for sustainability before and after redesigning a product based on the design guideline. To demonstrate the effectiveness of the modular product design, we carry out a case study with a coffee maker.

Product recovery has become a field of rapidly growing interest for product manufacturers as a promising solution for product stewardship as well as economic viability. As product recovery is a process highly dependent upon the way a product is designed, it should be considered early at the design stage so that the product may be designed to facilitate efficient and effective recovery at its end-of-life stage. To make a product easy to recover, manufacturing companies first need to understand the links between product design and recovery profit. They should be able to evaluate which design is better than others and why that is so. To accommodate such companies that seek for a design-for-recovery method, in this paper, a comparative study is conducted to analyze how design differences affect product recovery and what architecture characteristics are desirable from the end-of-life perspective. Three cell phone handset designs sharing the same design concept but entailing different architecture are created, for which the individual designs and the recovery potential of each design are evaluated under three different scenarios. The results highlight preferred design alternatives with their design implications for sustainable product design.

Circular Design

In the context of a circular economy, one can observe that (i) recycling chains are not adapted enough to the end-of-life products they have to process and that (ii) products are not sufficiently well designed either to integrate at best their target recycling chain. Therefore, a synergy between product designers and recycling-chains stakeholders is lacking, mainly due to their weak communication and the time-lag between the product design phase and its end-of-life treatment. Many Design for Recycling approaches coexist in the literature. However, to fully develop a circular economy, Design from Recycling also has to be taken into account. Thus Re-Cycling, a complete circular design approach, is proposed. First, a design for recycling methodology linking recyclability assessment to product design guidelines is proposed. Then, a design from recycling methodology is developed to assess the convenience of using secondary raw materials in the design phase. The recyclability of a smartphone and the convenience of using recycled materials in a new cycle are both analyzed to demonstrate our proposal. The Fairphone 2® and its treatment by the WEEE French takeback scheme are used as a case study.

Manufacturing Stage

Parts with complex geometry have been divided into multiple parts due to manufacturing constraints of conventional manufacturing. However, since additive manufacturing (AM) is able to fabricate 3D objects in a layer-by-layer manner, design for AM has been researched to explore AM design benefits and alleviate manufacturing constraints of AM. To explore more AM design benefits, part consolidation has been researched for consolidating multiple parts into fewer number of parts at the manufacturing stage of product lifecycle. However, these studies have been less considered product recovery and maintenance at end-of-life stage. Consolidated parts for the manufacturing stage would not be beneficial at end-of-life stage and lead to unnecessary waste of materials during maintenance. Therefore, in this research, a design method is proposed to consolidate parts for considering maintenance and product recovery at the end-of-life stage by extending a modular identification method. Single part complexity index (SCCI) is introduced to measure part and interface complexities simultaneously. Parts with high SCCI values are grouped into modules that are candidates for part consolidation. Then the product disassembly complexity (PDC) can be used to measure disassembly complexity of a product before and after part consolidation. A case study is performed to demonstrate the usefulness of the proposed design method. The proposed method contributes to guiding how to consolidate parts for enhancing product recovery.

Guidelines are recommended as a tool for informing user interface design. Despite a proliferation of guidelines in the research literature, there is little evidence of their use in industry, nor their influence in academic literature. In this paper, we explore the research literature related to mobile phone design guidelines to find out why this should be so. We commenced by carrying out a scoping literature review of the mobile phone design guideline literature to gain insight into the maturity of the field. The question we wanted to explore was: “Are researchers building on each others’ guidelines, or is the research field still in the foundational stage?” We discovered a poorly structured field, with many researchers proposing new guidelines, but little incremental refinement of extant guidelines. It also became clear that the current reporting of guidelines did not explicitly communicate their multi-dimensionality or deployment context. This leaves designers without a clear way of discriminating between guidelines, and could contribute to the lack of deployment we observed. We conducted a thematic analysis of papers identified by means of a systematic literature review to identify a set of dimensions of mobile phone interface design guidelines. The final dimensions provide a mechanism for differentiating guidelines and expediting choice.

Disability Simulation

Current product design methodologies are not conducive to creating inclusive products (products that meet the needs of persons with and without disabilities). In this paper, empathic design principles and modular product design strategies are explored as part of a novel approach to inclusive design. A disability simulation suit is used to test if empathically derived customer needs from persons without disabilities can serve as a proxy for the customer needs of persons with disabilities. This data collection methodology both increases the safety and ease by which customer needs can be gathered and gives designers an empathic design experience with the products they develop. This paper presents the techniques involved in and the preliminary data regarding the collection of customer needs on known product pairs. These product pairs perform the same function, but one is designed inclusively and one is not. Prior work on module identification from customer need statements is extended to specifically address the design of inclusive products. As part of larger research, this data will be used to make generalizations about the customer needs for inclusive products within the context of modular product design to create inclusive design guidelines, which will reduce the effort and expense involved in creating inclusively designed products.

Product recovery has become a field of rapidly growing interest for product manufacturers as a promising solution for product stewardship as well as for economic viability. Because product recovery is highly dependent on the way a product is designed, it should be considered in the design stage so that the product is designed to have high recovery potential. To make a product easy to recover, manufacturers first need to understand the links between product design and recovery profit and be able to evaluate which design is better than others and why. This study proposes a framework for analyzing how design differences affect product recovery and what architectural characteristics are desirable from the end-of-life perspective. For better design evaluation, an optimization-based model is developed, which considers product design and recovery network design simultaneously. For illustration, a comparative study with cell phone examples is presented. Three cell phone handset designs that share the same design concept but have different architectural characteristics are created, and the recovery potential of each design variant is evaluated under three different recovery scenarios. The results show that the framework can highlight preferred design alternatives and their design implications for the economic viability of end-of-life recovery.

Usability Analysis

Human-computer interface design guidelines are useful for developing well designed interfaces but the designer must be able to access the guideline appropriate to the application. Research is conducted to understand how designers access design guideline databases and then methods are tested to improve the usability of the databases. A design guideline database of approximately 300 guidelines is developed using a hypermedia approach. The system employs a book metaphor interface to characters and graphics in a Japanese environment. The subjects of the usability analysis are software designers who did not have any background in human factors. They were provided with the representation of a bad interface design on a piece of paper, and were instructed to improve the design through the use of the guideline database. Two common strategies were identified by observing the designers' actions: a hypothesis strategy and a checklist strategy. These strategies were analyzed using the quantities and quality of improvements recommended. The optimum database usage checks interface violations by employing the browsing function of the database; sometimes key word searches are used.

This article focuses on applying the ethics of the product features during the students’ design education. Good/Bad design term is a conventional approach to discuss the ethical/unethical design values of the products. It is noted that different aspects of the product design such as visual information design, interface design, and appearance design have a vital role in judging the levels of ethics in the product. So the students of product design everywhere need to practice the term ethical/unethical design during their study because designers influence society more than they could imagine. This influence can be done by creating an attractive organized appearance and perfect functions that support the ethical brand’s image to the customers. The interviews and discussions were held as a research method with the students of product design in some institutions in addition to some design experts and customers to find out their opinions about the design values that achieve the ethical dimensions in the product design. They can end up with products that carry ethical values in their design. The final article’s results are in the descending order of the different design values according to their importance in emphasizing the ethical aspects of the products, in addition to a checklist including some important questions that can help the designers to be more aware of ethics’ considerations in the product design because ethics is a process of learning, not a process of obedience, and to highlighting the term of ethical designer which in turn reflects on the ethics of customers and societies.
