Form gene clustering method about pan-ethnic-group products based on emotional semantic

The use of pan-ethnic-group products form knowledge primarily depends on a designer’s subjective experience without user participation. The majority of studies primarily focus on the detection of the perceptual demands of consumers from the target product category. A pan-ethnic-group products form gene clustering method based on emotional semantic is constructed. Consumers’ perceptual images of the pan-ethnic-group products are obtained by means of product form gene extraction and coding and computer aided product form clustering technology. A case of form gene clustering about the typical pan-ethnic-group products is investigated which indicates that the method is feasible. This paper opens up a new direction for the future development of product form design which improves the agility of product design process in the era of Industry 4.0.     

聚类模型在感性设计中的应用

随着技术的发展、社会的进步以及消费群体对产品感性需求的提高,以定性研究为主导的产品感性研究不能很好地适应产品设计的要求和消费者对产品的感性需求,因此消费者相应于产品感性的定量研究方法已越来越多地受到重视。依据聚类算法的特点,将调查所得到的数据进行聚类分析,寻找相近似消费群体的感性特性,并以此为基础建立产品设计的感性概念模型。以平板电视机为例,对上述方法进行实际应用探讨,具体方法是将平板电视机的设计元素分为多个层次,利用聚类算法将这些层次与消费者对平板电视机的感性意象相结合,并对其的形态、色彩等设计元素与感性意象进行聚类分析,探讨它们之间的相互适应关系,并推演出满足消费者感性的平板电视设计原型,以指导新产品设计与开发。

Concurrent Engineering based collaborative design Under network environment

Concurrent Engineering (CE) is a popular method employed in product development. It treats the whole product design process by the consideration of product quality, cost, rate of progress, and demands of customers.

Multi-criteria decision making and uncertainty analysis for materials selection in environmentally conscious design

Around the globe, manufacturers are increasingly trying to design products that are as ecological as possible, which is leading to the establishment of new design methods focused on environmentally conscious design (ECD). Materials selection, as a key element in ECD, differs from traditional design by introducing three additional requirements: life cycle viewpoint, consideration on environmental impact and cost, and uncertainties in the product life cycle scenario. This paper presents a new multi-criteria decision making (MCDM) model and uncertainty analysis method for the environmentally conscious materials selection problem. The model is based on engineering analysis and life cycle simulation, and is constructed in such a way so that it contains uncertainties to be explored and may be executed during product design; it considers such issues as manufacturing and post-use processes such as recycling. The TOPSIS method is employed, and uncertainty analyses are performed for model flexibility. The model is applied to material selection for PC housing. The case study shows that the decision-making analysis can provide useful design guidelines and a criterion for materials selection to achieve Environmentally Conscious Design.

Designing Visceral,Behavioural and Reflective Products

Designers and manufacturers often see consumption as the primary objective of a product–with implications such as discarded products,obsolete wastes,and ecological degradation.The paper aims to find the answer to the question,how emotional design can adapt the discarded and undesirable products into something valuable in a long term?This paper presents a framework combining Chapman’s theory and Norman’s theory on three levels of emotional design to highlight what long lasting connection with products entails.A design approach is presented combing the Wabi Sabi philosophy that promotes the celebration of decay and damage.This is used as one of the design principles for the experiments conducted on discarded products.Through constant user interaction before,during and after the experiments the evaluation of design as an agent of transformation is done.The user conducted the evaluation based on the Kansei elements of looks,sound,smell,and feel of the product.The experiments confirmed that a long-term value is only achieved through redesigning and reconstructing the perception of people towards products on a reflective level,rather than the visceral and behavioural elements of the product.The research found attachment to the visceral and behavioural elements of a product instead of an emotional one was causing users to discard products faster than required.The research indicated that many people,including designers and manufacturers,are unconsciously focusing on usability(behavioural level)and physical look(visceral level)of a product that are easily replaced,than on a meaningful way (reflective level)to create and maintain long-lasting emotions.The research concluded with a proposition towards digitization of products which could perhaps be an all round solution to make products more appropriate to human emotions.Digitization could give products the ability to capture,store and then communicate the stories,journey and memories back,in order to empower people to understand the value of longer-term use of products.
