Design as integration of axiomatic design and design structure matrix

Axiomatic design and design structure matrix (DSM) are two popular design methods at the moment, while most related researches only apply the basic ideas of axiomatic design or DSM to some use cases. This paper analyses the disadvantages of both axiomatic design and DSM. The axiomatic design method guides the designer finding suitable design parameters to meet the needs of function requirements. But axiomatic design cannot support the designer to know the interactions amongst the design parameters, including geometry, spatial layout, interfaces (e.g. logical and physical connectivity), which will decide the quality of the design. DSM has the advantages at recording and analysing the interaction relationship between existing product elements. However, at the conceptual design stage or for a new product that has never been designed before, it is difficult to make the DSM. After deep investigations, it has been found that there are strong complementarities between axiomatic design and DSM, and integration of both sides is advocated for better-quality design. The main outcome of this work is the formal interpretation of the integration logic between axiomatic design and DSM. Under such integration context, the conceptual design process can be seen as a recursive interaction of axiomatic design's design matrix (DM) and corresponding DSM. In this way, axiomatic design and DSM can benefit from each other. A computer-aided conceptual design system has been developed to realize the proposed integration model of axiomatic design and DSM.     

设计中的文化基因

设计作为一种生活方式的创造,直接或间接的改变着客观存在的观念、行为和物的形式,是文化延展的不可或缺的质变因子。在设计的过程中或多或少融入了许多人文思想与潜在的文化意识,文化在当今社会的设计领域更具渗透力,对设计的影响体现在设计定位与设计创意以及消费行为等方面,并具有时代性与地域性。

A survey of what customers want in a cell phone design

The cell phone is an information appliance that has been widely used. It provides instant access to information and makes people more 'connected'. The objective of our study is to investigate the relationship among the design features of the cell phone and identify the most important design features and design factors. In our survey study, we asked 1,006 college students using a 7-point Likert scale structured questionnaire to evaluate their preference of the design features and overall satisfaction of their current cell phone. Nine design factors were derived. Ten cell phone design features and five design factors that significantly impact a user's satisfaction were identified. The most important design features are: the physical appearance, size and menu organisation, which together account for 42% of the total variance of a user's overall satisfaction.

Filling 'gaps' in strength data for design

Data on the physical strength capabilities of users are fundamental to the safe and usable design of products. It is recognised, however, that there are many 'gaps' in the ergonomics data available to designers. Whilst considerable research on human capabilities and limitations has already been carried out, few data exist which are directly applicable in the design process. This paper describes a two-stage research project which was undertaken to try to address some of these data 'gaps'. Potential needs for design-relevant data were identified in Stage 1 of the research and in Stage 2 new data were collected to meet some of those needs. Data were collected on children through to the older adult on a series of six strength measurements, all of which were intended to be directly applicable to design: (1) finger push strength, (2) pinch-pull strength, (3) hand grip strength, (4) wrist-twisting strength, (5) opening strength, and (6) push and pull strength. The methodology, findings and data from this research are presented and discussed.     

如何制定网络安全策略

随着网络技术的发展，网络安全问题日益严重。安全性是网络逻辑设计中最重要的方面之一：但在网络设计过程中它经常被忽略，因为安全性通常被认为是运行的问题而非设计问题。然而，如果在设计网络之前考虑了安全性，就可以避免在已经完成的设计中加入安全措施时所带来的扩展性和性能方面的问题。我们应该在物理阶段开始以前就完成安全性设计，制定出有效的网络安全策略，并选择恰当的工具和产品以实施这些策略
