It is well known that mobile phones have been a indispensable communication tool for human life. The spiral springs are used as the main component of the semi-auto sliding mechanism of mobile phones. The characteristic of axiomatic approach is scientific and analytical method, and axiomatic approach is different from other design methods in offering the systematic method at an early stage of design. The axiomatic approach could determine design parameter and arrange the order of design and estimate the optimum design in good order. In axiomatic approach, the composition is divided by customer requirement, functional requirement, design parameter, and design matrix in large portion. This paper presents design in sliding mechanism for mobile phones by finite element method and axiomatic design.

본 논문은 제르멜로가 집합론을 공리화함에 있어서 힐버트의 공리적 방법을 차용하였다는 널리 무비판적으로 받아들여져 온 가정 자체를 검토하고자 한다. 그들이 공유했다고 가정되는 공리적 방법의 실체가 무엇이고 그것은 과연 어느 시기에 정립된 것인지를 묻는 데서 출발해서 공리적 방법에 관한 제르멜로와 힐버트의 사상이 어떻게 상호작용하며 발전해 나갔는지를 철학적 반성을 통해 규명하려는 것이다. 그 결과 후기 사상에서뿐만 아니라 심지어 전기 사상에 있어서도 제르멜로가 집합론 자체와 공리적 방법에 관하여 힐버트와 상당히 다른 견해를 지녔을 가능성을 확인할 것이다. 이러한 결과는 집합론의 역사와 공리적 방법의 역사, 그리고 나아가서 수학철학 전반에 걸쳐 상당한 함축을 지닐 수밖에 없다고 본다.

베르나이스는 국내외를 막론하고 그의 업적에 상응하는 집중적 관심의 대상이 되지 못했다. 극히 최근에 이르러 베르나이스의 저작의 재출간을 비롯하여 그의 철학에 대한 재조명이 시작되고 있다. 본 논문은 이러한 흐름에 발맞춰 공리적 방법을 초점으로 베르나이스의 사상을 힐버트의 사상으로부터 섬세하게 가려내는 시도를 시작해보고자 한다. 우선 힐버트가 자신의 공리적 방법에 대해 대단한 자부심을 지녔었다는 점을 전거를 제시해가며 부각시킨다. 그리고 힐버트의 공리적 방법이 공리적 방법의 역사 전체 안에서 어떤 위치를 지니는지에 관한 베르나이스의 견해를 정리해볼 것이다. 또한 중전기 베르나이스와 후기 베르나이스가 이 문제에 관하여 상당히 다른 입장을 취하는 것으로 보인다는 점에 착안하여, 중전기 베르나이스의 견해와 후기 베르나이스의 견해를 대조해 보일 것이다. 그리하여 공리적 방법에 관하여 가장 뚜렷하게 부각되는 힐버트와 베르나이스의 견해의 차이가 공리적 방법의 제일성의 문제에서 찾아진다는 점을 보여줄 것이다. 같은 맥락에서 1950년대 중반 이후 과학철학에서의 카르납의 프로젝트가 공리적 방법의 제일성에 대한 힐버트의 신념을 계승하려는 것으로 보고, 후기 베르나이스의 카르납 비판을 논의할 것이다.

When we use various multimedia programs such as 3D-game, visual conference, dial-pad phone by internet service, we make use of headset generally. As internet system is magnified more and more, a demand of headset will be increasing continuously. Because microphone was fixed by headset, it has many inconveniences for using headset. For these reasons, new concept headset is needed nowadays. Main idea of development of headset is very the automatic operation system of microphone. There are many process variables in appling new technology to the conventional headset. They can be solved by using axiomatic approach method which is very useful design method for designing new products. Its main character is scientific and analytical. The goal of this research is to design and manufacture a new headset model with axiomatic design method. In this paper, a new concept headset was presented by mapping the relation between functional requirements and design parameters.

Cold start of a fuel cell system is a major obstacle should be overcome as to commercialize it, especially for passenger vehicle applications. However, the cold start characteristics is so complicated since it involves various phenomenon such as ice-blocking in GDL, ionic conductivity in membrane affected by water activity with phase change, heat transfer through components such as bipolarplates or endplates, electro-chemical reactions affected by circumferential temperature and humidity as well. Axiomatic design provides a systematic method to investigate the complex phenomenon although it was developed as a methodology to establish logical design procedure by Nam P. Suh in 1990s. This paper presents a framework to approach the complex cold start problem using Axiomatic Design which features simplifying a problem through hierarchical decomposition and decoupling from the view of functional requirements and design parameters.

Axiomatic Design has been developed as a general design framework during past two decades and TRIZ has been developed for a design tool over 50 years. Axiomatic design is quite excellent in that the design should be decoupled. When a design matrix is established, the characteristics of the design are identified concerning the coupling properties. If the design is coupled, a decoupling process should be found. However, axiomatic design does not specifically indicate how to decouple. In this paper, a design method is developed to use TRIZ in the decoupling process. The decoupling ideas are extracted from the substance field analysis and various methods in TRIZ. The mettled is applied applied to the conceptual design of a beam splitter for the laser marker and the results are analyzed.

In order to execute the major role as the high density large capacity data storage device, which is one of the major characteristics of DVD(Digital Versatile Disk), there must be a method to effectively absorb the external impact or internal vibration. The DVD which has been developed until now tries to control two different types of vibrations, using only one absorber. But this goes against the independence Axiom of Axiomatic Approach which makes the design to be coupled. And in fat most of the malfunctions occurring during DVD data input/output is due to impact or vibration. Therefore in this paper, the vibration absorption system and operation reliability of DVD will be evaluated with the Axiomatic Approach and plans and feasibility to design an improved vibration absorption system will be provided also based on the Axiomatic Approach.

This paper proposes a design method for improving the disassembly by using the axiomatic approach. A product developer must design disassembly as well as assembly when designing the structure of a product. Axiomatic approach is a design tool that optimizes design. In this paper design evaluation method using information axiom sets impact variables and value function. As a result, examining the relationship between the functional requirements and evaluating the information can optimize designs.

The Design Axioms provide a general framework for design methodologies. The axiomatic design framework has been successfully applied to various design tasks. However, the axiomatic design has been rarely utilized in the detailed design process of structures where the optimization technology is generally carried out. The relationship between the axiomatic design and the optimization is investigated and Logical Decomposition method is developed for a systematic structural optimization. The entire optimization process is decomposed to satisfy the Independence Axiom. In the decomposition process, design variables are grouped according to sensitivities. The sensitivities are evaluated by the Analysis of Variance(ANOVA) to avoid considering only local values. The developed method is verified through examples such as the twenty -five members transmission tower and the two -bay-six-story frame.

As the rotational speed of optical disk drive is increasing nowadays, the reliability to vibration and shock becomes more important. For this, various of rubber vibration isolators are being developed by varying the shape and hardness. But it is difficult for the hardness of common used rubber to be lowered below Duro 30 degrees, and because of the shape complexity of rubber vibration isolator there are difficulties of analysis. Microcellular foamed vibration isolator has various cell densities and cell sizes, so it can vary the stiffness and damping coefficient. In addition, its hardness can be lowered below Duro 30 degrees. Axiomatic Approach is very useful design method for designing new product or new process. Axiomatic Approach's character is scientific and analytical method. In this paper, developing process of microcellular foamed vibration isolator for DVD is presented with Axiomatic Approach.
