3.1. The TRIZ Method to Introduce the Innovative Design of the Drainage Cover for Rapid Cleansing
3.2. Innovative Design and Universal Design to Introduce a Quick-Cleansing Drainage Cover
- Equitable use: This design will not cause any harm to any user, and the weight of the drain cover will be the maximum weight, which makes it easy for operators of all sizes to operate.
- Simple and intuitive: This design is easy to understand regardless of the user’s experience, knowledge, language ability, or concentration. In the drainage cover’s design, the anti-sludging track of the rail is used to make the drainage cover operate in a single direction, and the drainage cover can be easily operated in an intuitive manner.
- Low physical effort: this design can be used effectively, comfortably, and effortlessly. The loose fit of the sliding rail of the drain cover and the push block enables the push block to push the hair and foreign matter without difficulty.
