Excellence in function and performance is one of the key reasons for a product to sustain its market competitiveness. Upgrading of products, including those of the adaptable-function products, is necessary to ensure their market attractiveness. Current research that is specifically on upgrading of adaptable-function products is lacking. To this end, this paper attempts to study both functional aspect and performance aspect of upgrade design of this kind of products. For the former, the study focuses on some fundamental issues of functional upgrading relevant to the upgrading type, where an analogy-based functional upgrading strategy is proposed. The proposed work is illustrated by the functional upgrading of an electric drill design case. For the latter, the study focuses on how to evaluate the upgrading priority, for which a number of performance attributes to be upgraded are specified. For this purpose, the technology potentials for enabling the upgrade design (which should be maximized) and the influence caused by the upgrading (which should be minimized) are first studied. Based on technology potentials and upgrading influence, the priority ranking is evaluated to help the designer making performance upgrading decisions. Finally, a case study of upgrading a multifunction machine tool is presented, which demonstrates the feasibility of the proposed evaluation method. With the help of the established upgrading design prototype and the strategy of upgrading priority ranking guidelines, the designers can get the relevant design support during their upgrade design process.

AbstractDuring the design of complex systems, a design process may be subjected to stochastic disruptions, interruptions, and changes, which can be described broadly as “design impulses.” These impulses can have a significant impact on the transient response and converged equilibrium for the design system. We distinguish this research by focusing on the interactions between local and architectural impulses in the form of designer mistakes and dissolution, division, and combination impulses, respectively, for a distributed design case study. We provide statistical support for the “parallel character hypothesis,” which asserts that parallel arrangements generally best mitigate dissolution and division impulses. We find that local impulses tend to slow convergence, but systems also subjected to dissolution or division impulses still favor parallel arrangements. We statistically uphold the conclusion that the strategy to mitigate combination impulses is unaffected by the presence of local impulses.

Abstract The EBD-SIM (evidence-based design, simulation) framework is a conceptual framework developed to integrate the use of lighting simulation in the EBD process to provide a holistic performance evaluation method. A real-time case study, executed in a fully operational office building, is used to demonstrate the framework’s performance. The case study focused on visual comfort analysis. The objective is to demonstrate the applicability of the developed EBD-SIM framework using correlations between current visual comfort metrics and actual human perception as evaluation criteria. The data were collected via simulation for visual comfort analysis and via questionnaires for instantaneous and annual visual comfort perception. The study showed that for user perception, the most crucial factor for visual comfort is the amount of light on a task area, and simple metrics such as Eh-room and Eh-task had a higher correlation with perceived visual comfort than complex performance metrics such as Daylight Autonomy (DA). To improve the design process, the study suggests that, among other things, post-occupancy evaluations (POEs) should be conducted more frequently to obtain better insight into user perception of daylight and subsequently use new evidence to further improve the design of the EBD-SIM model.

The issue of environmental sustainability, which is unprecedented in both magnitude and complexity, presents one of the biggest challenges faced by modern society. Engineers, including mechanical engineers, can make significant contribution to the development of solutions to this problem by designing products and processes that are more environmentally sustainable. It is critical that engineers take a paradigm shift of product design i.e. from cost and performance centered to balance of economic, environmental, and societal consideration. Although there have been quite a few design for environment (DfE, or ecodesign) tools developed, so far these tools have only achieved limited industrial penetration: they are either too qualitative/subjective to be used by designers with limited experiences, or too quantitative, costly and time consuming and thus cannot be used during the design process specially during the early design stage. This paper develops a novel, semi-quantitative ecodesign tool that targets specially on early design process. The new tool is a combination of environmental life cycle assessment, working knowledge model, and visual tools such as QFD, functional-component matrix, and Pugh chart. Redesign of staplers is selected as a case study to demonstrate the use of the proposed tool. Efforts are on going to confirm that the new design generated using this new tool does have improved environmental performance.

Construction supply chain management (cSCM) requires planning such that construction stages and logistics are coordinated and integrated to reduce costs, improve productivity, and generate a win–win situation for different parties. The supply chain operations reference (SCOR), which has been widely applied in other industries, is a standardized operational modeling methodology for analyzing supply chain processes. This study considers construction industry characteristics in applying the SCOR model to develop a dynamic cSCM model using computer simulation. Furthermore, this study developed a novel cSCM performance evaluation method using the SCOR method to evaluate cSCM performance and identify and solve cSCM problems. This study uses a bridge construction project as a case study, which determines the relationships among supply chain participants to enhance communication efficiency and identify problems related to materials management. The case study results demonstrate that the proposed hybrid modeling methodology helps construction supply chain participants identify their roles and communicate easily, helps project managers identify bottlenecks in a supply chain, and significantly improves cSCM performance.

Design Thinking is a human-centred approach to problem solving and innovation that exploits design theories and methods to solve ill-defined problems. Recently it has been a popular subject of real-life applications in research and industrial endeavours for its original way to combine creative and analytical thinking, what is desirable from a human viewpoint with what is technologically feasible. This paper focuses on the application of Design Thinking in paediatric orthodontics. Through the analysis of a design case study, the paper picks up the threads of the challenges of devising a facemask for maxillary malocclusion. The case study shows how a Design Thinking mindset can make a holistic and creative approach flourishing, bringing together different competences at any stage of the design process. The methods of design allowed to translate the different languages of the stakeholders into a single narrative where the people’s journeys are clearly depicted, monitored, and supported.

New Type

As the number of vehicles continues to grow in China, the problem of urban traffic congestion gets more serious, particularly at intersections. As a new type of unconventional intersection, the displaced left-turn (DLT) intersection has been widely recognized to improve the efficiency of intersections with heavy left-turn traffic flows. Converting an existing intersection into an intersection with additional DLT lanes is a valuable solution. However, the studies on DLT intersections mainly focus on performance, applicability, and safety. The guidelines on the specific engineering design process mostly come from experience, and the study on the considering multifactor design method is still insufficient. Therefore, this paper proposed an evaluation and analysis model of the lengths of added DLT lanes based on the entropy evaluation method, in which VISSIM and Surrogate Safety Assessment Model (SSAM) software were adopted for simulation. A design process for the length of the added DLT lanes was proposed with this model. An urban intersection in Xi’an was taken as a case study, and the application of the model and the design process was studied in detail. After selecting four evaluation indicators, the model was applied to calculate and analyze the optimal length of the added DLT lanes under 45 different traffic volume combinations. The recommended lengths of different situations were within the range recommended in the guidebook published by Federal Highway Administration. The results of the case study proved that the model proposed in this paper was advanced, reasonable, and practical.

The brand is a powerful representational and identification-led asset that can be used to engage staff in creative, sustainable and developmental activities. Being a brand the result of, foremost, a design exercise, it is fair to suppose that it can be a relevant resource for the advancement of design literacy within organisational contexts. The main objective of this paper was to test and validate an interaction structure for an informed co-design process on visual brand artefacts. To carry on the empirical study, a university was chosen as case study as these contexts are generally rich in employee diversity. A non-functional prototype was designed, and walkthroughs were performed in five focus groups held with staff. The latter evidenced a need/wish to engage with basic design principles and high willingness to participate in the creation of brand design artefacts, mostly with the purposeof increasing its consistent use and innovate in its representation possibilities, whilst augmenting the brand’s socially responsible values.
