With the advanced development of society and economy, roads have resolved the problems of transportation, and streetlights have become indispensable tools. At the same time, in the current times with promotion of public environment beautification and public aesthetics, the form design of streetlights have become a key to elevating urban environmental beauty. Secondly, the growing potency of environmental ideals, shortage of energy, endless growth of various costs, and the fact that streetlights use considerable amounts of electricity, a pressing issue is how to make streetlights save energy. Furthermore, in order to make products competitive, a comprehensive and systematic design procedure and development process is significant. However, traditional systematic design procedures have been serial processes, which tended to produce problems of interaction and feedback, resulting in waste of money and time. Thus, this dissertation will use the strategy of concurrent engineering to make up for the insufficiencies of systematization. Concurrent engineering is the operation of parallel strategies to conduct planning and design for a product and its related processes. In the beginning, it can already consider all factors of the product’s entire lifecycle. However, currently some domestic corporate design procedures still use the traditional design procedures, so that much manpower and costs are wasted in the design process. Thus, the key to future product design is how to integrate the concept of simultaneity in the design procedure. In view of this, this study integrates the design strategies of concurrent engineering and systemization, and uses energy-saving streetlights as the design example to design a conceptual product, in order to understand this design procedure and the pros and cons of the steps. The study first uses Image Scale Method to conduct product orientation and conceptualization, and uses Quality Function Deployment (QFD) to analyze user needs and provide a weighted evaluation of product concept function and structure. Then, it uses Finite Structure Method (FSM) and Synectic Trigger Mechanisms (STM) to use the structural creative development and appearance design found from weighted evaluations to capture the feasible design concept. Then, the PUGH method and Design for Assembly (DFA) are used for concept evaluation, and finally Value Engineering (VE) analysis is used to make detail evaluations and modifications before completion of this design. Results of the study show: in product analysis, use of the Image Map Method and Quality Function Deployment Method can efficiently determine the product orientation and design direction. In developing design, using the FSM and STM methods, supplemented with the PUGH conceptual selection method, it can indeed provide rational design creative thinking and choices for designers, in order to shed light on the black box of product form design, allowing later designers to take over in the development of conceptual design processes and results. In the stage of design evaluation, the use of DFA and VE can allow designers to consider functional design, structure design, assembly procedures, and costs in the process of design development, which allows the preemptive resolution of potential problems in production, and elevate product value and quality. This result not only combines energy concepts such as solar energy and wind energy in the design of streetlights, which not only saves energy but also considers the overall form design and landscape needs, to achieve lowering of product assembly costs and elevation of economic value, so that these streetlights are more competitive.
