Laundry drying is a daily chore that every family endures. In Taiwan it is worse as the available area is limited, urban areas are densely populated, the winters are wet, and thunderstorms often occur on summer afternoons. Improving on the traditional laundry drying rack could make it an indispensable part of modern life improving the quality of life for everyone. This study uses TRIZ to improve the traditional bamboo design. First, this study collects and analyses literature related to the traditional bamboo design. Second, it then utilizes a contradiction matrix, 39 engineering parameters, and 40 invention principles in TRIZ to find the places that need to be improved and subsequently improves them. Finally, an intelligent laundry drying rack was created using sensors to detect light and rain. These synchronously trigger the control circuit, and drive the motor, so that the laundry is smoothly moved inside from outside, making laundry drying more convenient and safer.
