Product Design Process

Tolerancing is an essential part of a product design process. It is traditionally performed after the product structure has been determined. The product precision requirements may not be fully utilized for the decision making for selecting the best structure in the early stage of product design — the conceptual design phase. A growth design method has been proposed for product structure design and concurrent tolerancing, in which the product form and tolerance can be generated in the same way as an organism grows. The basic feature of biology, cell division, has been borrowed as the design guiding principle. Product conceptual model has been built as the basis of form and tolerance growth design. The relationship of product function, structure and tolerance was analysed to explain on what and how they act in product design process. Tolerance mathematic model expressed by screw parameters and expression model based on Technologically and Topologically Related Surface (TTRS) are described to execute the tolerance allocation. The automation selection of Datum reference frame (DRF) can facilitate the generation of tolerance. Finally, a prototype form design and tolerancing system has been implemented and applied to a dedicated fixture design to verify the validity of the growth design.

In order to reduce the information chaos of product design, we present the main motions of Design-Element based product design that we call itDE-PD. Different from traditional product design process composed of function, style, or customer requirements etc.al,DE-PDis driven by the knowledge and information flows in product design iteration. InDE-PD, the product is composed of Design-Elements (DE) which is the integration of related knowledge and information. After discussing the definition and information construct ofDE, we present the iteration ofDEbased product design. To evaluate the method, a design case of beach motorcycle with limit mount ofDEsis conceived. Evaluation results show thatDE-PDis a promising approach for product design informatization.

Nowadays a general platform has played an important role in the product design process. As the traditional similarity measure used in module division is to the design stage in which the features and set are static, it is impossible to find the similar components in alterative design stages. For this reason, a new common platform design method on extension-distance is presented. According to build the relative function, the threshold used in the key module identification is easy to generate. Then the tolerance-constraint functions in the customized components division for the common platform generation. Then the adaptability measure is used to find the optimal case in the database. The measure has been used in the gasoline saw common platform design process.

Product Design Process

Today, the interdisciplinary design approach has been quickly adopted as a new trend in the modern product design process. Whereas, it is believed that manufacturers try to make shortcuts in order to reduce the time-to-market. Therefore, many inherent or uncertain safety parameters and factors are normally ignored in the early stage of the process until problems occur during the life cycles of products. This is very harmful to users. Enterprises may face liability claims and recalls of those products. In addition to the claims, additional time and cost are required to investigate the root cause of problems and to redesign the products and. Those problems mostly happen in some developing countries in which their product design and manufacturing process is still in a labor-intensive mode. Systematic and knowledge-based design approaches have not yet been popularly adopted. In order to have a better consideration, in terms of safety at the early stage of design process, the integration of practical experience of safety assessment concept and analysis methods into the traditional electronic product design process is the key proposed idea in this paper. A new design workflow with safety assessment concept at the early stage is generated, with a result of saving redesign cost and time.

Aiming at the existing problems in the process of product modeling and structure design such as of no visualized appearance, low efficiency and the easy interference of parts, a Pro/E-based product design method is proposed which, in the component pattern, conducts three-dimensional design by considering core component as reference and creates the rest parts according to modeling surface. This method effectively prevents the easy interference of parts during the process of product design, ensures the precise alignment among parts and avoids design repetition, thus greatly improves the design efficiency. Its application in the process of intelligent data acquisition terminal product design has proved the high efficiency and practicality of this design method.

The usability design is also an important part in product design process. Product is a service, but we often confused about the operation of the product in our daily life. So far, the theoretical researches about the usability have been widely investigated. However, the methods of usability are seldom researched in the process of design. In this paper, easy to learn and easy to use of the product which are fully consider and won't have wrong operation in the design are advocated. Principles and affecting factors of usability are analyzed in the design. The methods of usability are proposed at the beginning of the design and in the process of late. According to the principles and influencing factors, it shows that the design method of usability is easier to design a rational product with high performance and practical value.

AbstractA design problem with deficient information is generally described as wicked or ill-defined. The information insufficiency leaves designers with loose settings, free environments, and a lack of strict boundaries, which provides them with more opportunities to facilitate innovation. Therefore, to capture the opportunity behind the uncertainty of a design problem, this study models an innovative design as a composite solving process, where the problem is clarified and resolved from fuzziness to satisfying solutions by interplay among design problems, knowledge, and solutions. Additionally, a triple-helix structured model for the innovative product design process is proposed based on the co-evolution of the problem, solution, and knowledge spaces, to provide designers with a distinct design strategy and method for innovative design. The three spaces interact and co-evolve through iterative mappings, including problem structuring, knowledge expansion, and solution generation. The mappings carry the information processing and decision-making activities of the design, and create the path to satisfying solutions. Finally, a case study of a reactor coolant flow distribution device is presented to demonstrate the practicability of this model and the method for innovative product design.
