Most existing educational design approaches focus on discipline-specific modules, while those based on a generic product concept rarely target sustainability goals. With the increasing interest in sustainability and education for sustainable development, it is necessary to rethink the product design approaches to target both customer needs and community requirements for sustainability. The main goal of the integral design approach proposed in the present work is to create a broader picture that integrates the design process, life cycle analysis, and the role of each design and life cycle player. A wider management scheme that sets a clear road map of the contribution of all players is introduced. This scheme is based on a win-win strategy between different players to promote mechanisms to enhance sustainability and min-imize risks and socioeconomic footprints.

This paper describes efforts taken to further transition life cycle analysis techniques from the latter, more detailed phases of design, to the early-on conceptual phase of product development. By using modern design methodologies such as automated concept generation and an archive of product design knowledge, known as the Design Repository, virtual concepts are created and specified. Streamlined life cycle analysis techniques are then used to determine the environmental impacts of the virtual concepts. As a means to benchmark the virtual results, analogous real-life products that have functional and component similarities are identified. The identified products are then scrutinized to determine their material composition and manufacturing attributes in order to perform an additional round of life cycle analysis for the actual products. The results of this research show that enough information exists within the conceptual phase of design (utilizing the Design Repository) to reasonably predict the relative environmental impacts of actual products based on virtual concepts.

Purpose This paper aims to examine the dynamics of a community of practice (CoP) through a case study of eCars – Now! They offer open-source blueprints of the electric conversion kits globally. The authors analysed the CoP by considering its entire life cycle, starting from the motives for its establishment, through its active performance, up to the current stage, where the members need to decide whether the community will remain viable. Particular attention was paid to the group dynamics and issues that seemed relevant to the change in dynamics which determine whether a CoP maintains its vitality or dissipates. Design/methodology/approach The qualitative case study was chosen as the research strategy (Yin, 1984) to answer the research question and understand the target phenomenon of the CoP by analysing textual data. This particular case was chosen because of its unusual revelatory value for the case CoP which aims at creating a tangible innovation by using a platform that normally aims at intangible problem-solving (Eisenhardt and Graebner, 2007). In the data collection, the authors used method and researcher triangulation (Patton, 1990). Findings Life cycle analysis revealed four themes that explained the change in the group dynamics and the dispersal of the community: differentiation and dispersal of interests, growth that resulted in role differentiation, virtuality in community development and inclusion of investors. The themes were all related to the fact that the case community operated with not only knowledge, but also with a tangible product. Therefore, the tangibility of a problem to be solved seems to play a pivotal role in a CoP’s operations and dynamics and, in part, also explains the changing role of information and communications technology (ICT) in the process. Research limitations/implications However, this paper identified also different ways to characterize community participation, which was also relevant from group dynamics point of view. Thus, the topic should be studied further. Group dynamics in general, as it relates to the success of CoPs, should be also investigated further. Additional studies should implement the inclusion of external resources in the community. Further research is also needed to investigate tangible and intangible outcomes achieved through CoPs. Much of the available research was conducted over short periods; prolonged interactions in a CoP context could show different results. Practical implications In conclusion, at the beginning of the life cycle of the eCars community, ICT played a significant role. It helped increase awareness of the community in the first place and enabled people to join in, which thus enabled the community to evolve. When the operations evolved and the life cycle progressed, both the physical meeting place as well as personal interaction and communication became emphasized and much more important. In the maturing stage, the role of ICT, and especially social media, is the essential part of the community. Social implications This analysis suggests that at the early stage of a community, the plans can be somewhat random, even utopian, but when the community evolves, this uncertainty can become a problem. First, it affects achieving the actual, and in this case, concrete results. Second, uncertainty and unclarity dampen enthusiasm and motivation, which are of utmost importance due to the voluntary participation. This paper also concludes that when the operations evolved and the life cycle progressed, both the physical meeting place as well as personal interaction and communication became increasingly important. Originality/value This paper argues that the ideological basis for this kind of community should be openness. All information should be available for everyone who registers to the community platform on the internet. This community was working in the mindset of open innovation. Technical documentation and all other material were available for everyone in the community’s wiki pages, which attracted a lot of people who were delighted by eCars. Many advisors delivered technical information and good advice to the practitioners of the community through the platform. The hang arounds were also very well-informed in this stage regarding how the core group was working.

Abstract Prior work has demonstrated the integration of detailed life-cycle assessment into a traditional design modeling process. While a full life-cycle assessment provides insight into a product’s potential impact on the environment, it is often too time consuming for analysis during conceptual product design, where ideas are numerous and information is scarce. The work presented in this paper explores an approximate method for preliminary life-cycle assessments without detailed modeling requirements. Learning algorithms trained on the known characteristics of existing products allow the environmental impacts of new products to be approximated quickly during conceptual design. Artificial neural networks train on product attributes and environmental impact data from pre-existing life-cycle assessment studies. The product design team queries the trained artificial model with new high-level product attribute data to quickly obtain an approximate impact assessment for a new product concept. Tests based on simplified inventory data have shown it is possible to predict impacts on life-cycle energy consumption, and that there is a basis for the method to be used in also predicting solid material, greenhouse effect, ozone layer depletion, acidification, eutrophication, winter smog, and summer smog.

Design for environment principles and guidelines help designers create greener products during the early stages of design when life cycle analysis is not feasible. However, the available guidelines are not exhaustive and a general methodology for discovering guidelines has yet to be proposed. In this paper, a method for identifying green design guidelines is presented, which aims to fulfill the need for more comprehensive guidelines. The method combines typical aspects of product design, such as customer needs analysis, with reverse engineering and life cycle analysis. Although reverse engineering is commonly applied to studies of disassembly and recyclability, the methodology and case study herein show how reverse engineering can be applied to areas of product utilization and energy consumption in particular. A general description of the methodology helps readers apply it to their own studies, and a case study of electric kettles shows how each step of the method was applied to reveal four new design guidelines.

Consumers might be willing to repair their broken devices as long as the associated repair costs do not exceed an undesirable threshold. However, in many cases, the technological obsolescence actuates consumers to retire old devices and replace them with new ones rather than extending the product lifecycle through repair. In this paper, we aim to investigate the impact of components' deterioration profiles and consumers' repair decisions on the lifespan of devices, and then assesse the anticipated life cycle environmental impacts. A Monte Carlo simulation is developed to estimate the life cycle characteristics such as the average lifespan, the number of failed components' replacement, and the total repair cost per cycle for a laptop computer. The lifecycle characteristics estimated from simulation model further have been used in a life cycle assessment (LCA) study to quantify the environmental impact associated with different design scenarios. The results reveal the impact of product design as well as consumers' repair decisions on the product lifespan and the corresponding environmental impacts.
