Abstract

The rain sensing for automatic window closure product is an innovation to close the window once the rain is detected using a rain sensor. This is because many country is under the area of a tropical rain forest climate that got an optimum average of rainfall. The aim of this project is to safe the property in the house such as the furniture that are easily damages when exposed to the wet of rain drops, thus can avoid waste of money to replace the item for a new one. The specific thing about ergonomics, customer, environment, cost, safety and standards, aesthetics, operation, life in service, product life span, market, material, patents, performance, quality and reliability, testing and weight are calculated. After brainstoming, the project is continued by project management, survey the market analysis, product specifications, a concept generation, a concept selection and a concept testing. Then, a new material is selected by using CES software. An analysis on the design is done through conducting FEA and fatigue analysis by using Solidwork software. After a research is fully done, the prototype of the product is made for five week duration. Finally, a written report for the Bachelor Project 1 (PSM 1) and Bachelor Project 2 (PSM 2) are completed. Secara keputusannya, nilai faktor keselamatan yang diperoleh dari analisa statik bagi gabungan bahagian pengehad penggerak dan bahagian penggerak tidak akan gagal pada faktor keselamatan 2.50 Mpa apabila tenaga putaran 1 N.m digunakan. Selain itu, bahagian silinder akan gagal apabila faktor bebanan dibawah nilai 1.0 apabila daya 50N dan 100N dikenakan bagi 1000 kitaran. Manakala, bahagian-bahagian yang lain tidak akan gagal terhadap daya 100N.
