Abstract: In view of high energy consumption situation in the apparel industry in the background of green economy, the author explores the multi-functional structural design method for single garment and the diversified wearing forms of single product according to the study on clothing style change, so as to satisfy the individualized and special needs of consumers. This not only improves the energy efficiency of clothing materials, but also optimizes life cycle of products, and accordingly promotes the environment-friendly clothing philosophy and provides new solution to the contradiction between mass production and individualized consumption of garments.

Abstract: Human performance seems to be neglected in the design of assembly and disassembly of a product despite the increasing awareness among people on green environmental issues. Incorporating an ergonomics evaluation can be considered as an alternative empirical solution to tackle the issue efficiently. Therefore, the objective of this study is to investigate human performance with reference to muscle activity while performing assembly and disassembly of manual tasks focusing on load variability. Upper limb muscle activities were investigated in this study. Twenty participants were asked to perform assembly and disassembly of selected tasks at two load-levels. The results of this study indicated that load tasks affect human performance. The findings from this study highlighted that the muscle activity for the medium load task was prone to fatigue faster than the low load task (28.19% in average). Thus the study has revealed the importance of incorporating the ergonomics principle solution in the design of assembly and disassembly tasks to increase human performance.

Abstract: Modern industrial design has been extended to the whole product life cycle of production, manufacture, sale and recycling from traditional appearance design and product performance. Facing today’s intense and diversification market competition, product design must be taken the whole product life cycle routes based on design, quality, economic and environmental protection. Starting from the design, designer should concern about the product life cycle of the product in each stage of the design process, and use design principles and methods for product design reasonable. With quality competitive as the basis for product, with economic environmental competition as improve quality of power, industrial design can provide high quality product and create a perfect user experience, in order to reduce pollution and satisfied our clients’ needs. In this paper, industrial design processes and methods for product life cycle are discussed and analyzed systematic, so as to product designers of the designer to provide methodology.

Abstract: In order to realize information sharing and interchange of complex product multidisciplinary collaborative design (MCD) design process and resources. The Process integrated system control of product multidisciplinary collaborative design was analyzed firstly in this paper, then design process of complex product for supporting multidisciplinary collaborative was introduced, a detailed description is given of the organization structure and modeling process of MCD-oriented Integration of Product Design Meta-model ; and concrete implement process of process integrated system control method was introduced to effectively realize information sharing and interchange between product design process and resources.

Abstract: A method for evaluating the ease of disassembly of products was presented in this paper. In order to conduct more objective evaluation and reduce the fuzziness and subjectivity in evaluation process, the disassembly evaluation model based on the principal component analysis (PCA) was proposed in this paper. The evaluation metrics mainly incorporated factors closely related with disassembly process, and the principal component analysis enabled more objectively quantitative evaluation, through dimensionality reduction and information integration of metrics. Finally, an example of disassembly evaluation was given to verify the effectiveness of the method.

Abstract: In order to precisely describe material texture image and establish a quantitative relationship of the materials objective parameters and the subjective feeling, here, this article takes the typical plastic material as example and uses the method related with Kansei Engineering as study method. The study of material texture image experiment was conducted by discriminate analysis, cluster analysis, multidimensional scaling, semantic differential method and so on to quantified consumers perceptual cognitive on materials, and to build a mathematical model by neural network. This study could provide a theoretical basis for materials selection in industrial design.

Abstract: A hydraulic steel radial gate (SRG) with two oblique arms is designed by using topology optimization and size optimization. Topology and size optimization are carried out by using CAD software, e.g., Hyperworks. In the current design, the SRG is initially considered to have three main components, i.e., the arms, the supporting frame of arms and a panel for water retaining. To give a better design of these components, e.g., arms and its supporting frame, topology optimization is adopted. By topology optimization method, the shape of arm and the supporting frame are obtained. As construction of the new SRG is reconstructed by the components obtained, the stiffness, strength and stability of the new SRG is checked and some sizes of components in SRG are readjusted by using size optimization. The final design of the SRG is around 24% lighter than the traditional design whilst the safety of the new design is much better.

Abstract: Fixture systems have a great importance in modern manufacturing and assembly because of the high number of scenarios in which they are used. Fixture design is a complex task since the system effectiveness depends both on position and type of locators. Several authors deal with the problem of determine the most suitable design for fixture systems but their investigation is commonly limited to the evaluation of the effects due to the locators position. In the present work a design method is proposed to evaluate the fixture systems considering also the locators type. Since it is possible to model the fixtures as multi-performance systems, the comparison is performed by introducing appropriate sensitivity indexes. The effectiveness of the design method is proved through the application to an automotive case study.

Abstract: Product conceptual feature modeling based on energy saving is established. Through having decomposed the general functions, product design information of every function unit is extracted and converted into energy eigenvector. The combination of every function unit becomes functional chain and the function model is got. Using the bond graph and state space theory, principal analysis and behavior modeling is developed. Structure modeling is established based on function modeling and behavior modeling, comprehensively considered energy consumption influencing factors in structure modeling. Function-behavior-Structure modeling is put forward and product conceptual feature modeling based on energy saving is realized.
