Interior panels are usually used in finishing of interior walls for not only decorative effects but also information transfer. According to designer's design placing interior panels may need repetitive tasks and the emphasis of this paper is to support an automation of these tasks. Considering the utilization characteristics of interior panels, we propose three method to present patterns by using bitmap image pixels and interior panels' shape changes, based on the theoretical consideration. In addition, in order to approve the possibility of the proposed methods, we have implemented the BIM based interior panels auto layout tool which applied one of the three methods to present patterns by using bitmap image pixel values and panel identification attributes. This tool also supports auto generation of quantity and panel arrangement sequence information that will be used in future construction phase. We expect that this approach will also be used in other decorative objects which require repetition of the basic units, such as floor tiles.

The most critical issue in free-form buildings is how to construct the free-formed exterior facade panels. Their geometric complexity delivers many cons and problems in fabricating and constructing their shapes. To construct a free-form building, first of all, its skin has to be chopped into small pieces, which is called panelization. After panelization, the panels go through an optimization process to construct them economically. The panel's geometries are modified or regenerated through this optimization process. In this study, the panel optimization process of free-form buildings are performed through a case study. The panel shapes of the case study are modeled with Digital Project. To test the constructability of the various panels, 8 mock-up panels are made and laser scanning technology is applied to measure the preciseness of the panels manufactured in comparison with their original design.

지난 회에서는 형태와 형태이면에 있는 구현의 논리를 모두 다룰 수밖에 없는 파라메트릭 툴의 성격에 대하여 간략하게 이야기 해보았고 이를 반증할수 있는 곡면상의 패널링의 예를 살펴 보았습니다. 삼차원 곡면으로 인해 발생하는 패널들의 시각적 왜곡 및 구축상의 어려움을 해결하고자 왜곡이 발생하는 물리적인 이유를 이해하고 이를 미적분의 개념을 빌어 해결해 보았습니다. 오늘 살펴볼 예도 이와 비슷한 미적분의 개념을 빌리게 되지만 문제의 해결을 위함이 아닌 자연 현상을 시뮬레이션 하고 시뮬레이션의 결과로 얻어진 데이터를 설계에 반영하기 위함이라는데에 차이가 있다고 할 수 있겠습니다. 오늘 살펴볼 내용은 Harvard GSD에서 대학원 설계 수업의 일환으로 제가 진행하였던 파라메트릭 디자인 워크샵의 결과물이며 추후에 이를 실무에 이용하게 됩니다.

The design trend of information technology is quickly changed with the times. The design trend of information display is a bezel-less display, recently. The bezel-less display or edge-less display is a new trend of mobile phone display. In this study, the shading tape was manufactured for assembling process of touch panel display with the high screen-to-body ratio so-called bezel-less display. The shading tape was fabricated on PET film with the UV curable acrylic pressure sensitive adhesive(PSA) by roll-to-roll process. The UV curable PSA was synthesized with the eco-friendly toluene-less manufacturing method. The adhesive power of manufactured shading tape was investigated by motorized tensile testing machine. The thixotropic, maintaining property of cutting shape, was characterized by field emission scanning electron microscope. As results, the shading tape exhibits high adhesive power and good thixotropic performance suitable for assembly process of touch panel display. The functional shading tape will be expected to improve productivity of assembly process of touch panel display.

The fact that office environment is a principal factor affecting work efficiency is widely accepted. Under such a circumstance, developing relocatable office wall systems is highly required. Psychological, physiological, and economical factors, along with physical factors, should be considered to develope a office wall system. More specifically, competitive price, relocatable efficiency, structural stability, fast installation, health and safety, and aesthetic satisfaction are typical determinants. The evaluation results of newly developed wall system are as below: 1) Panel structural system added with the merits of frame structural system can be studied to accomplish minimal disruption to workplace and better finish details. 2) To cover up the existing interior defects such as uneven floor and ceiling, flexible solutions must be studied especially when panel structural system is accepted. 3) More consideration must be given to finish materials, section details, sound blocking and absorbtion to enhance the satisfaction level.

Design was developed through user-oriented service design methodology and survey was conducted on material selection criteria for prototype production to select CFRP (Carbon Fiber Reinforced Plastics) CNT (Carbon Nano Tube), which was applied to animal X-ray detector panel to design product and develop prototype. Completed prototype with the application of CFRP CNT panel was tested in drop test, frontal external pressure test, and dustproof/waterproof performance to confirm that it can be utilized as a portable animal X-ray detector used in outdoor environment.

본 글을 통해 학생들과 함께 수행한 다양한 디지털 디자인 모델을 기반으로 5가지의 디지털 패브리케이션 방식을 적용하여 여러 실제 인테리어패널의 제작 과정 및 그 결과물들을 요약적으로 소개하였다. 해당 과정은 기존의 분리된 설계와 제작 및 시공이 아닌, 설계-제작 통합적인 접근방법을 활용함으로써 학생들로 하여금 디지털 디자인과 패브리케이션의 효과를 극대화 할 수 있음을 체득하도록 하였다. 패브리케이션 기기 및 재료 등의 차이점에 따라 실제 구현된 모델과 원래의 디지털 모델과의 형상적인 차이점은 아직까지 한계점으로 남을 수 있지만, 비정형적으로 생성된 디지털 디자인의 형상이 직접적으로 실현이 가능하다는 점에서 의의가 있다고 할 수 있다. 또한 패러매트릭 모델링 기법이나 실제 제작 경험이 거의 없는 학생들을 대상으로 개별적인 교육이 아닌 설계-제작 통합적인 교육을 실시함으로써 각 요소들이 어떻게 유기적으로 관련되어 디지털 디자인 과정이나 패브리케이션과정에서 상호 보완적으로 중요한지 직접 체득할 수 있도록 하였다는데 의의가 있다. 본 글에서 소개한 재료를 깎는 등의 방식인 "마이너스"의 방식이 아닌 3D프린팅과 같이 재료를 이용해 만들어가는 "플러스"적인 방식 또한 해당 사례에서 수행되었으며 마찬가지로 다양한 특성을 지니고 있으나, 본 글에서는 전자의 방식에 대해 주로 논하였다. 본 글에서 다룬 제작기법뿐만 아니라 3D프린팅 기술의 발전과 보급에 따라 디지털 패브리케이션 역시 다양하게 진보하고 있으며, 팹랩 등을 통한 학교에서의 건축설계 교육도 다양하게 진화하고 있다. 본 사례 및 기타 실험적인 교육과 선도적인 여러 시도를 통해서, 디지털 디자인과 패브리케이션 영역을 확장시켜나가고 해당 기술의 발전에 적극적으로 보조할 수 있는 교육과정을 수립하고 이행하는데 일조 할 수 있기를 희망한다.

The interior space in a passenger car is consisted with many partial elements, and the instrument panel is the most important part from all of them, which is designate the total image of the interior design and the space variation, drivability and safety of the interior space. ] The instrument panel of a passenger car in the early age had the concept of a wall between the engine room and the passenger cabin on which the instrument for the driver were fitted. Therefore the central mounting of the instruments was the typical feature regardless of the position of a driver seat. As the automobiles became more functional with many equipments, driver oriented instrument panel with energy absorbing materials had been developed, and that was the beginning of the various instrument panel design of these days. The recent instrument panels of passenger car have the tendency of going back to the central instrument mounting as it was at the past on a few cars for the strict safety regulation, a new production technology and for the enhanced drivability. It can be summarized into a few results as these with the analysis of a few recent instrument panels. -minimizing the total volume for the better frontal visibility. -energy absorbing and passive structures for the strict impact regulations. -revival of central instrument mounting for the convenience and safety through minimizing the difference of the focal length of a driver.

Although the use of CAD and CAM technologies has been broadly adopted by architecture-engineering- construction-facility management (AEC/FM) industry as the means of producing complex forms, there are still remained issues such as reducing cost, and enhancing quality and manufacturability. In this paper, to resolve given issues, we suggest a process of rationalization in digital architecture design and fabrication as an integrated approach. The rationalization, which is usually used as the term related with the skin panel of free-form architecture, is a process of re-designing a digital model to meet the requirements of manufacturing considering the gap with an original designs. Thus we classified this process and conducted a case study of fabricated models as an exploratory study. As the result, we found that each phase is connected with other phases with the circulation of information and rationalization process can be determined as the circulative process which re-designs digital model by minimally deviating from the original design based on the information deducted from analysis of inter-compatability of software and requirement of hardware.

본 연구에서 개발할 설계기술은 부가가치가 매우 높은 소량 다품종 건축용 내 외장재의 금속 패널코너가공법에 관한 것이다. 금속 금구류 및 건축용 내 외장재로 사용되는 2.5mm이상 되는 금속강판을 사용함에 있어서 가장 문제가 되는 직각코너링 접합부위에서 발생되는 내식성(수명성), 내후성, 및 미려성(디자인)을 향상시키므로 품질의 향상뿐만 아니라 소량 다품종의 생산성을 증대시킬 수 있는 국내 최초 금속패널 코너가공을 할 수 있는 벤딩다이시스템(Bending Die System)을 설계하고자 한다.
