In order to utilize a numerical simulation on a product development for electronic equipment, not only the simulation techniques themselves, but the application technologies of the simulation in the product design, were examined. The design process of electronic equipment was categorized into four stages, which were a concept, a function, a layout and a parameter design. Each design stage consists of a specifying that a human decide the specification for the next stage and a verification whether the specification satisfy the previous stage requirements. The specifying and the verification are conducted over and over again. Numerical simulation is corresponded to the verification and is used to accelerate this iteration instead of experiments. The examples of numerical simulation corresponding to these four verifications were shown in the present paper. There are few examples in last two type of simulation. The progress of the numerical technology for function and concept verification is expected. The product development process requires not only numerical simulation based on physics but also statistical approach.

In every product development industry, automation plays a key role in increasing the throughput of the company and providing better planning in product development and improved product quality. It is very necessary to find a solution to interdependencies during the product development process. During simulation-based analysis of a product, it is required that the need for actual hardware of the product is to be eliminated. Because of this, the functionality of the actual hardware can be analyzed by using software using simulations. If simulations of different products are running, the data is to be exchanged between different simulations effectively. It can be considered as simulating data exchange, as it is implemented in the hardware form. A proper and suitable method is to be used to have this goal achieved. This paper will address the integration approach for application code simulations or programs that are built to perform specific tasks.

Abstract Simulation based design methodologies have the potential to streamline the development and continuous improvement of complex products by addressing three fundamental aspects of team-based product development initiatives: coordination, collaboration, and optimization. On-going research funded by the Office of Naval Research is seeking to augment its baseline simulation based design environment with enhanced system integration, visualization, and optimization capabilities that address these three aspects of the product development process. The inherent strengths of the existing software environment are being leveraged to support the development of these enhanced capabilities including Multi-Disciplinary Optimization methodologies that will enable the rapid convergence on high payoff system alternatives.

Lighting products are essential for our modern life nowadays, but they also produce high negative impacts on the environment. Although there are tools and methods available for reducing the environmental impact of lighting products, it is a challenging task to integrate them throughout the product development process. To overcome the challenge, this research developed an approach to integrate tools/methods relevant for the eco-design through product development process to reduce the environmental impact of lighting products. Six types of methods, such module design, and 30 tools, such as lifecycle assessment software packages, are considered in the integrated approach. The product specification with eco-constrains is established for implementation at each design stage to ensure the product eco-features. The approach was applied in the development of an LED table lamp which was then assessed in comparison with a benchmark LED lamp regarding environmental lifecycle impact and lighting performance. The comparative assessment results indicate that the LED lamp developed with this approach is much better than the benchmark lamp.

In electronic equipment, thermal failure and thermal degradation are two increasingly prominent problems of the devices, with the deepening integration and growing power density. Currently, there are relatively few reports on the heat transfer mechanism, heat source analysis, and numerical simulation of electronic equipment containing power electronic devices (PEDs). Therefore, this paper carries out thermal design and evaluates the cooling performance of PED-containing electronic equipment. Firstly, the basic flow was given for the thermal design of PED-containing electronic equipment; the heat transfer mode of PEDs and the equipment were detailed, so was the principle of thermal design; the cooling principles were introduced for ventilation cooling, heat pipe cooling, and closed loop cooling. Then, numerical simulation was carried out on the solid and liquid state heat transfer of PEDs and the equipment under different cooling modes. Based on an engineering example, the cooling scheme was finalized through heat source analysis on the proposed electronic equipment. The experimental results rove the effectiveness of numerical simulation and electronic equipment cooling scheme. The results provide a reference for the cooling scheme design for other fields of thermal design.

Abstract Producing environmentally benign products has now become one of the key challenges of companies across the globe. It can be achieved by utilizing the ecodesign tools in product development process for reducing the environmental impact of products during the design stage itself. Although, the ecodesign tools are available in abundance but there is a lack of studies that can help companies to identify suitable tools. A novel approach has been developed in this study which assists companies to identify and adopt effective ecodesign tools. In this study, three companies related to different product categories are included for testing the proposed approach. Results show that ‘Ecodesign Checklist,’ ‘Material, Energy, Toxicity (MET) Matrix’ and ‘Life Cycle Design Strategy (LiDS) Wheel’ are the three most effective ecodesign tools among the tested tools. Also, it is realized that if these three ecodesign tools are customized and integrated together in a specific sequence then it can be used by the designers, especially novice designers, as an ecodesign methodology. This methodology has the potential to guide designers in the form of a step by step approach during environmentally conscious product development.

Digital tools have become indispensable for the testing and modification of prototypes in mobile and industrial machine manufacturing. Data that are extracted from virtual experimentation and analysis are both affordable and valuable, due to their repeatability and because they are close to real-world observations. Expert knowledge is a prerequisite for full deployment of computer aided engineering tools in the design phase and concomitant stages of product development. Currently, such knowledge, for the most part, is provided by the product development team and the manufacturer. Yet, it is important that manufacturers and designers receive end-user feedback throughout the product development process. However, end-users often lack sufficient know-how about the technical and engineering background of the product development, and this lack of understanding can become a barrier to user-designer communication. The aim of this article is to present an alternative to traditional design approaches that is based on customized real-time multibody simulation. This simulation-based approach can be seen as a platform that has the potential to improve knowledge management systems for product development. End-user feedback to the designer is given in a systematic manner throughout the design process using a multipurpose XML-based multibody environment.
