Patents pay more attention to creativity. The novelty of the idea is a necessary condition for applying for a patent, and the simplicity of the technical scheme does not affect it. 1. Your idea is really novel. No one else has applied for a similar patent. You can definitely apply for a patent, and the chances of passing it are very high. 2. Your search database is not wide enough. For example, if you only search a database (Wanfang, HowNet), you can't judge whether your creativity is novel or not. Patents are divided into appearance type, invention type and utility model. If your idea is novel enough, I suggest you declare both invention and utility model. If your idea is not novel enough, but it is practical, I suggest applying for a utility model. The pass rate of utility model patents is very high.
