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。

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.

PERIODIC DEFORMATION OF PARAMETRIC SURFACE

Deformation is a powerful tool for geometric modeling and design. Such a tool can be used to create a new shape from existing shape without restarting whole design process. A new mathematical model for producing controllable periodic deformations is proposed. By introducing cosine extension functions construct a shape operator matrix and then use the matrix to transform the position vector of some points on the object surface so as to create the deformation effects. Because the cosine extension (Unctions have a number of variable parameters with different properties, the method has corresponding interactive control means. The user can manipulate those parameters to get desirable periodic deformation effects. Experimental results show that the method is feasible and applicable to engineering and research fields such as sheet metal forming by stamping and CAD.

A novel method of reverse engineering using axiomatic design

Reverse engineering has been widely used to analyze existing objects such as software systems, products, etc. The main purpose is obtaining information by disassembling a product and finding an improved design. Based on the disassembling work, research for a systematic analysis has been well developed, but reverse engineering has been rarely employed in finding a new (an improved) design of a complex and large scale product. Therefore, even though the ultimate goal of reverse engineering is an improved design (or redesign), the opportunity to make a new feature is rarely given. A novel method of reverse engineering is proposed by using the axiomatic design viewpoint. The method not only keeps the fundamental concept of reverse engineering, but also realizes a new (or improved) design according to proposed procedures such as inference, design improvement module and a qualitative evaluation. A complex and large scale product (a ceiling type air conditioning system) is chosen as a case study to validate the proposed method. As a result, useful information for a new (or improved) design is obtained and also a new part (filter cleaning system) is proposed. The methodology provides a good way to design a new (or improved) product.

A quality function deployment methodology with signal and noise ratio for improvement of Wasserman’s weights

Quality function deployment (QFD) has attracted much attention in not only the quality management field but also other engineering fields. The original concept of QFD is focused only on the voice of customers, which means that the needs of customers should be satisfied from the design stage of products. However, some problems were found in using subjective and qualitative data when constructing a house of quality (HOQ). To solve the problems, Wasserman presented a methodology to consider correlation weights on the top matrix of HOQ, but the weights are subjective data and can not guarantee consistency and objectivity. The Wasserman’s weights are randomly determined under subjective conditions. This research applies Taguchi’s robust design method as another method for obtaining the HOQ top matrix weights. With the new weights, S/N-QFD is deployed, and the result of S/N-QFD is compared with W-QFD. As an application example, with a real process and quality data of a representative company product, the relationship and the correlation between the process characteristics and the quality characteristics are analyzed. Finally, this paper presents a new QFD processing methodology to determine the weights with more consistent and objective data.

Analysis of Physical Friction Characteristics about Handwrite Feeling—Rough and Smooth

Writing was an important factor in human society since long time ago. And previous studies indicate many consumers evaluate pens in handwriting feeling above all other factors when they select recently pens. The fact they work always grabbed in hands considered, the emotional design of writing tools is essential. However, the feeling such as handwriting feelings is gradually disappearing due to the development of mobile devices. So we thought that the need for an engineering approach. The technology of the sense of touch belongs to the technology of the sensibility field, but it is positively necessary to objectify the sense of touch in order to develop new technologies or products by expressing this numerically and applying it to engineering. In order to objectify the sense of touch, the variables (the pressure, temperature, texture of material, etc.) of the friction when the stylus pen first touches the surface of the object should be digitized. And static and dynamic friction models should be established and the variables that affect the friction behavior should be organized. This study investigated the handwriting feeling of various writing tools and attempted to use it for the development of new mobile devices in the future through physical friction test. This study investigated the handwriting feeling of various writing tools and attempted to use it for the development of future mobile devices through physical friction test. Using developed model which can explain how the experimental parameters and emotional user experience, developer can design their product which can give user expected emotional sensibility.     

Development of a percentile based three-dimensional model of the buttocks in computer system

There are diverse products related to human buttocks, which need to be designed, manufactured and evaluated with 3D buttock model. The 3D buttock model used in present research field is just simple approximate model similar to human buttocks. The 3D buttock percentile model is highly desired in the ergonomics design and evaluation for these products. So far, there is no research on the percentile sizing system of human 3D buttock model. So the purpose of this paper is to develop a new method for building three-dimensional buttock percentile model in computer system. After scanning the 3D shape of buttocks, the cloud data of 3D points is imported into the reverse engineering software(Geomagic) for the reconstructing of the buttock surface model. Five characteristic dimensions of the buttock are measured through mark-points after models being imported into engineering software CATIA. A series of space points are obtained by the intersecting of the cutting slices and 3D buttock surface model, and then are ordered based on the sequence number of the horizontal and vertical slices. The 1st, 5th, 50 th, 95 th, 99 th percentile values of the five dimensions and the spatial coordinate values of the space points are obtained, and used to reconstruct percentile buttock models. This research proposes a establishing method of percentile sizing system of buttock 3D model based on the percentile values of the ischial tuberosities diameter, the distances from margin to ischial tuberosity and the space coordinates value of coordinate points, for establishing the Nth percentile 3D buttock model and every special buttock types model. The proposed method also serves as a useful guidance for the other 3D percentile models establishment for other part in human body with characteristic points.
