The Model Building Research of Product Innovation Design Quality Based on QFD and KANO

The original of product design innovation move from driving by technology innovation to customer needs, technical innovation and service pattern’s CTS driving(Customer Needs、Technological Innovation and Service).The previous theory of product design did not suit to new environmental factor and also did not reflect and synthesize other factor for product design.QFD is a system method which transform customer needs to definite measure for design product or design service. The theory of KANO provide five types of customer needs, with analyzing the needs of customer in order to provide design direction for product design. Paper research with the main line of QFD, through HOQ technique of QFD, delivering customer needs to designer, utilizing KANO model to identify various kinds of needs, through the transform of importance degree, sequencing importance degree of AHP for customer needs, combining above all so that clarify direct of design in order to ensure the quality of design.

Tactile Value Expressed in the Design of Madeleine Vionnet

As designs that simulate man's five wits are important, all five senses used are complex. Tactil value by Bernard Berenson means that the object in fine art makes the spectator feel like his or her finger is touching something, although the spectator is distant from the art piece. Especially as costumes have a relationship with the flexible skin and moving body, tactile modality and tactile value is more important. In order to analyze how Madeleine Vionnet realized a new femininity through the application of the principal of tactile value to dress design and in order to define tactile value in the field of fashion, this study examines the theory of tactile value, sculpture, painting, contemporary art, and product design as well as the design of Madeleine Vionnet from 1925 to 1937 because she was in the fashion business enlarging dress shops in New york during this period. The shape of Madeleine Vionnet's dresses made the concealed body alive through organic curves pressed against the body from cuts and dissections based on the anatomy of a supple body with curves and movement. In the garments, soft physical characteristics or the glossy touch of silk or pile textile imitated smooth skin while colors similar to a woman's eye, hair, and skin color continue the impression of the dress extending to the body through these design elements, Madeleine Vionnet's dresses reinforce the will to touch female body hidden under the dress by tactile values, not by the body's modification or visual exposure.

New Progress Concerning Research of Product Design Theory and Methods

The product design theory and methods based on “the Scientific Outlook on Development” have been set up by our group in recent 10 years, The new progress concerning Research of product design theory and methods include: 1) QCTES was instead of IQCTES including six requirements of product design; 2) traditional design stages were replaced with four new stages including investigation, planning, implement and inspection; 3) green design was replaced with harmonious design; 4) traditional design method was replaced with deep-layer design method; 5) concept and connotation of product top-layer design were proposed; 6) more detailed contents of product synthesis design method were advanced. We got good effects to apply above product design methodology on many product designs recent years.

Consistency Maintenance of Collaborative Product Design Based on the Semantics Reasoning

Consistency maintenance is a key problem in collaborative product design. Firstly, based on product design theory, the semantics relationships described by XML among components in collaborative product design system are made. Secondly, the associated components are determined through backward and forward semantics reasoning. Finally, the data is updated by constraints solving, and the consistency maintenance is achieved.

Toward a Biopolitics of Injury: Wounding in American Legal Culture

Interdisciplinary research is more often realized in rhetoric than in scholarship. With Injury ', Sarah Lochlann Jain offers an original and at times brilliant example of the intellectual insight that can result from work that crosses the bounds of science and technology studies, the study of law and society, and social theory. Jain examines in detail the short-handled hoe, the computer keyboard, and the cigarette. Each of these chapters is written around a series of cases in which a group of people have claimed to have been injured by the product. Jain takes an interdisciplinary approach to her study, deftly linking readings of legal cases, archives, popular culture, and critical theory to understand the sociality of objects in thick relation to the people who claim injury. Thus, she situates each legal case in a rich historical account of the objects, combined with what she calls a semiotic reading. By doing this, she offers analysis of how bodies and objects come to be coded in relation to one another. Neither judges nor juries can claim immunity from the co-constitution of bodies and objects. In using anthropology's central strength of reading broad social structures through the details of everyday life and interactions, Jain is able to show what each discipline has to gain from such cross-pollinations. As a result, science and technology studies scholars will be required to think more carefully about power as it is implicated in race, gender, and all manner of social and physical difference. Law and society scholars will be introduced to the complexities of analyzing the relationships among humans and the world of objects. And social theorists will have a new opportunity to examine how multiple frameworks of analysis history, gender and race theory, advertising, product design, law, and legal theory can be brought together to better understand and theorize contemporary life.

Two-Sided Network Effects: A Theory of Information Product Design

How can firms profitably give away free products? This paper provides a novel answer and articulates trade-offs in a space of information product design. We introduce a formal model of two-sided network externalities based in textbook economics—a mix of Katz and Shapiro network effects, price discrimination, and product differentiation. Externality-based complements, however, exploit a different mechanism than either tying or lock-in even as they help to explain many recent strategies such as those of firms selling operating systems, Internet browsers, games, music, and video. The model presented here argues for three simple but useful results. First, even in the absence of competition, a firm can rationally invest in a product it intends to give away into perpetuity. Second, we identify distinct markets for content providers and end consumers and show that either can be a candidate for a free good. Third, product coupling across markets can increase consumer welfare even as it increases firm profits. The model also generates testable hypotheses on the size and direction of network effects while offering insights to regulators seeking to apply antitrust law to network markets.

Structured modeling group support systems: a product design theory

Structured modeling is critical to the design, development, and implementation of many systems including computer software, business processes, and data networks. Since the creation of structured models relies on the knowledge of many organizational stakeholders, groups often accomplish this task. Group support systems (GSS) focus on the support of group processes and would appear to be useful for structured modeling; however, GSS usually only provide textual or decision related output rather than the structured models needed for many design processes. This paper proposes a class of systems, structured modeling GSS (smGSS), which adds support for the development of structured models to standard GSS. Since past research has shown that research results may be difficult to compare across studies when the system under investigation is not well defined, this paper develops a product design theory that defines the required characteristics of and testable design propositions for an smGSS as derived from existing theory and empirical investigations.

A science-based approach to product design theory Part I: formulation and formalization of design process

This paper, first of the two parts series, addresses a science-based approach to the study of design processes. Design process is an evolving process that begins with design requirements and ends with product descriptions. A general design governing equation is proposed to characterize the design process. We also proposed a design process model that embodies synthesis and evaluation processes, design problem redefinition process, and design decomposition process. The basis of the design process model is primitive design which is formalized as a six-step process. Any design problem can be decomposed into primitive designs. Utilizing the design representation scheme we established using set theory, the design process is mathematically formulated and formalized. The detailed explanations are provided to illustrate the design governing equation, the design process model and the mathematical formulation.

A science-based approach to product design theory Part II: formulation of design requirements and products

The Design Process begins with design requirements and ends with product descriptions. The design requirements include both structural and performance aspects. The product descriptions deal with the structural aspect of the design requirements while the product performances describe the performance aspect of design requirements. In this part of the paper, a set theory-based representation scheme is proposed to represent design objects in the design process, including design requirements, product descriptions, and product performances. This representation scheme can represent the design objects that evolve in dynamic design processes. The entire mathematical scheme is defined based on structural and behavioral properties. Within one uniform scheme, the design objects are represented at different levels of complexity and abstraction. Several examples are included to explain the scheme and its mathematical formulations. The proposed scheme can be used for science-based studies of product design.
