Honestly, I do not know! BUT inventions are made with the goal in mind to create possibilities that then make them useful. Therefore, it is necessary to study experience gained in creative activities and to focus on the characteristics of good solutions that differ from bad ones by analyzing important inventions or patents. Your observations can then be used to solve problems in inventing. The inventing concept works by discovering and eliminating the contradictions in the product or system. I wish you lots of success and good achievements.
