Conventional window cleaning method has a number of limitations, for example, workers dependent and high crash risk. The purpose of this study is to derive the performance requirements of a window cleaning apparatus through technology survey. For this, we investigated the domestic and international patents related to window cleaning, and interviewed experts in the field of window cleaning and mechanical design. Through this research, we have proposed performance requirements of the window cleaning apparatus.

Recently, needs for the window cleaning for 2~5 stories in a building has been increased but existing window cleaning work by workers is not easy to clean the windows. Therefore a demand for development of alternative techniques have been raised. The purpose of this study is to analyze feasibility of development of the guide rail-type cleaning device for cleaning window for the lower stories. For this, we analyze the status of the job, such as risk, limitations of by workers and examine the potential producer needs through interviewing field experts of the cleaning work. Futhermore, we define the required features of the window cleaning device and proposed the validity of the relised device development of the function.

Recently researches on the window cleaning robot are being conducted actively. Moving mechanismsof these window cleaning robots are divided into two categories, which are towed type and walking type. Towed type is focused on fast cleaning on the flat surface of building and walking type has priority on cleaning task on relatively complex surface with overcoming obstacles. Currently commercialized towed type window cleaning robot has weakness that it is hard to adhere closely with the wall and easy to be affected by wind. In case of walking type it has the problem that the position errors are continuously accumulated during motion. In this paper, we propose new towed and walking type mechanism which can compensate previous weaknesses. After that we estimate the performance of each proposed mechanism by simulation.

In order to overcome the limitation of conventional cleaning method by workers, variety attempts to develop a window cleaning apparatus has been tried. However, the existing cleaning devices were lack of consideration for avoiding projection parts of the window such as frames or profiles. In this study, operating mechanism of cleaning tool for avoiding the projections parts using a two-axis robot is proposed. Proposed mechanism is that a wiper are reposed in a relatively stationary in the vicinity of the projection and avoided the projection in this state. It is expected that the mechanism is the base of driving cleaning tool part in the new window cleaning apparatus.

Recently, a variety of window cleaning devices have been developed. There are, however, few cases of anticipated problems and countermeasures that may arise after these devices are installed. Therefore, in this study, the emergency condition was derived and the emergency scenario was derived for the rail-mounted cleaning device. Emergency scenarios and countermeasures derived from this study will be used for continuous improvement and supplementation of cleaning devices through prototyping and testing.

The purpose of this study is to analyze the work of the existing manpower dependent cleaning method by investigating the window cleaning site. In this study, detailed work contents were confirmed by on-site investigation and interview with experts, and the relationship, procedure, repetition work, and time required for each work were analyzed. The future analysis results will be used as a basic data for comparative analysis of productivity and economical efficiency with the window cleaning device to be developed.

In case of developing a guide-rail type window cleaning robot, only the first prototype has been developed. In this study, it was considered that the size and the load of the window cleaning robot was not optimized, and through the structural analysis of the self-weight of the window cleaning robot, the stress concentration area was derived and the concentrated stress was quantified. Analysis showed that the upper rail shaft had a bending stress of 9.964Mpa and the bolt had a shear stress of 19.544Mpa. The results of this study will be used as basic data for designing future prototypes.

As businesses put a greater emphasis on outward appearances, the demand for external window cleaning has been on the rise. However, with the conventional labor-intensive window cleaning method, it is hard to meet this demand. Therefore, this study proposes a Life Cycle Cost (LCC) analysis model for a guiderail-type cleaning robot, and estimate the LCCs of the conventional method and the cleaning robot. The findings of this research are expected to serve as a guide for future development of a cleaning robot.

In the past, the results of window cleaning work have been judged subjective and complaints about cleaning results are being raised. In this study, we tried to quantify the evaluation of the cleaning result. For the quantification of the evaluation, a colorimeter was selected and the basic experiment was carried out. In addition, this study examined the use of standard dust powder for artificial production of contaminants in glasses. Further evaluation and analysis will be carried out to quantify the evaluation criteria of the cleaning results.

유리창 청소작업은 인력의존적이고, 고소에서 불안정한 자세로 수행하여 추락위험이 상존하는 작업이다. 따라서 작업원의 안전도 향상 방안이 시급한 상황이다. 본 연구에서는 건축물 외부 유리창 청소에 대하여 개념설계를 제시하고, 제시된 개념모델에 대한 경제적 타당성을 분석하였다. 제시된 모델은 창틀 등 돌출부를 회피하며, 상하부의 형상이 상이하더라도 대응이 가능하도록 고안하였다. 고안된 개념모델의 경제성을 분석한 결과, 편익비용 비율이 4.48로 1을 크게 상회하였다. 따라서 제안된 유리창 청소장치의 경제적 타당성은 충분할 것으로 기대된다. 본 논문에서 분석한 결과는 유리창 청소장치의 개발, 마케팅 등에 활용될 예정이다.
