Abstract Over the last few years there has been a flurry of activity in the study of the mechanical design process. This has been fostered by a perceived lack of efficiency and resulting quality in U.S. product designs compared with those of the Japanese and the Europeans. Research activity is broad and has varied over areas as diverse as: the development of computer codes using AI techniques to solve specific problems requiring expertise in a narrow domain; the commercialization of general, parametric design tools; and the modeling of the human cognitive design process. As results have been published, it has become obvious that the term “design” means different things to different researchers. The field is mature enough to allow techniques and results to be classified, compared and contrasted. However, this is difficult because there is no agreed upon description of the types of design and design studies. In other words, there is a need for a taxonomy to characterize the mechanical design process and the research on it.

Traditional Construction Techniques

Parametric modeling, usually considered modeling tools, has been analyzed in this chapter in a different way: as design tools for architect. First the use of parametric design has been considered from different approaches. Starting from the approach of Kas Oosterhuis Architect, in the Saltwater pavilion (1997), or Peter Cook Architect in the Kunsthaus (2003), in which the parametric tools have been used as shapes generation tools. Until the approach of the Japanese architect Kengo Kuma, in the Sunny Hills building (2013), where the parametric tools have been used to rethink traditional construction techniques in a parametric way, known as chidori. After the analysis of the different parametric approaches, a new perception on the architectural design will be provided. In particular, the analytic way and the creative way, are usually separated in the architectural design, and it will enhance their interaction, in some cases, they become the same thing. This approach makes explicit and evaluable parts of the design process, reducing the gap between concept and goal in the design.

Design Process Model

Background: In the whole design process of modular fuel tank, there are some unreasonable phenomena. As a result, there are some defects in the design of modular fuel tank, and the function does not meet the requirements in advance. This paper studies this problem. Objective: Through on-the-spot investigation of the factory, a mechanical design process model is designed. The model can provide reference for product design participants on product design time and design quality, and can effectively solve the problem of low product design quality caused by unreasonable product design time arrangement. Methods: After sorting out the data from the factory investigation, computer software is used to program, simulate the information input of mechanical design process, and the final reference value is got. Results: This mechanical design process model is used to guide the design and production of a new project, nearly 3 months ahead of the original project completion time. Conclusion: This mechanical design process model can effectively guide the product design process, which is of great significance to the whole mechanical design field.

AbstractIndustrial buildings play a major role in sustainable development, producing and expending a significant amount of resources, energy and waste. Due to product individualization and accelerating technological advances in manufacturing, industrial buildings strive for highly flexible building structures to accommodate constantly evolving production processes. However, common sustainability assessment tools do not respect flexibility metrics and manufacturing and building design processes run sequentially, neglecting discipline-specific interaction, leading to inflexible solutions. In integrated industrial building design (IIBD), incorporating manufacturing and building disciplines simultaneously, design teams are faced with the choice of multiple conflicting criteria and complex design decisions, opening up a huge design space. To address these issues, this paper presents a parametric design process for efficient design space exploration in IIBD. A state-of-the-art survey and multiple case study are conducted to define four novel flexibility metrics and to develop a unified design space, respecting both building and manufacturing requirements. Based on these results, a parametric design process for automated structural optimization and quantitative flexibility assessment is developed, guiding the decision-making process towards increased sustainability. The proposed framework is tested on a pilot-project of a food and hygiene production, evaluating the design space representation and validating the flexibility metrics. Results confirmed the efficiency of the process that an evolutionary multi-objective optimization algorithm can be implemented in future research to enable multidisciplinary design optimization for flexible industrial building solutions.

Key Features

This paper describes the task/episode accumulation model (TEA model) of non-routine mechanical design, which was developed after detailed analysis of the audio and video protocols of five mechanical designers. The model is able to explain the behavior of designers at a much finer level of detail than previous models. The key features of the model are (a) the design is constructed by incrementally refining and patching an initial conceptual design, (b) design alternatives are not considered outside the boundaries of design episodes (which are short stretches of problem solving aimed at specific goals), (c) the design process is controlled locally, primarily at the level of individual episodes. Among the implications of the model are the following: (a) CAD tools should be extended to represent the state of the design at more abstract levels, (b) CAD tools should help the designer manage constraints, and (c) CAD tools should be designed to give cognitive support to the designer.

In view of sofa product’s features such as demand of great types and inefficient design, the paper presents a method of parametric design on the simple sofa based on RhinoScript. With analysis of simple sofa’s modeling characteristics, the model of simple sofa could be presented by different parameters. Then models of different sizes and appearance styles could be created easily and quickly by inputting different parameters. This method improves the design efficiency and avoids industrial designers’ repeat work. The design process of a kind of simple sofa testified the method and a series of sofa proposals were easily generated.

Abstract This paper investigates a computer environment approach for the exploration of design behavior in the mechanical design process. Generic component types and behavior modelers are developed based on the needs of mechanical designers and are represented in a computer environment. Built-in component types and physical behaviors are also developed. Extension can then occur as needed during design refinement. The resulting system can support exploration and knowledge refinement during design.

Abstract This paper describes the roles of features and abstraction mechanisms in the mechanical design process, mechanical designs, and product models of mechanical designs. It also describes the relationship between functions and features in mechanical design. It is our experience that many research efforts exist in the areas of design and product modeling and, further, that these efforts must be cataloged and compared. To this end, this paper culminates with the presentation of a multi-dimensional abstraction space which provides a unique framework for (a) comparing mechanical engineering design research efforts, (b) relating conceptual objects used in the life cycle of mechanical products, and (c) defining a product modeling space.

Design Proposal

The paper is concerned with topology optimization in the mechanical design process. The disadvantage of current process of mechanical design is discussed and a new design process based on structural topology optimization is presented. The design process with structural topology optimization in mechanical design is discussed by the example of the frame of a bender. Static analysis is made to the original model first according to the whole structure and working characteristic of the machine, the stress and deformation distribution are obtained and then topology optimization is carried out. On the basis of topology optimization, the layout of the initial design proposal is obtained and the weight of the frame is substantially reduced while the performance enhanced. The application of the method demonstrates that through innovative utilization of the topology optimization techniques, the conceptual proposals can be obtained and the overall mechanical design process can be improved substantially in a cost effective manner.
