My Future Invention!

I’m not good at creating nor making something, but if I would be an inventor, I would like to create two useful and low-cost things for everyone. The most useful item in my mind is a changeable carpet. For example, we bought a tiny condominium in 2017, and we have not changed our carpet yet. It came from the previous owner, and we are not sure how many years they had used it. In addition, we have a lot of terracotta pots for indoor plants, so the carpet is getting dirty especially in front of our windows because they need much sun. If I would create many sheet of carpets in one like post it papers, we could make clean our floor without many processes, and we also could enjoy nice carpet colors often. This idea sounds more sanitary, and it would be good for changing interior, too. My second idea is an incredible shelf. For instance, we have a dishwasher which is broken. If we turn on it, it never stops. When we moved here, we tried using it, and it kept working more than 5 hours, so we gave up. Instead of washing dishes, we are using it as a wine cooler. My imagination is that outside would be a normal dishwasher or a shelf, but inside would be a huge space like a big storage. Recently, we have to stay home as much as possible, so we have so many food stocks just in case. If I would open the magic shelf, inside would be deep and wide, and we could put anything we want such as many food cans, a huge pack of rice, a beer case, kitchen papers and so on. This idea is perfect for many people who live in the tiny houses like us. My two imaginations would sell anywhere like Home Depot, Sears, or other furniture stores, and they would be low cost with good qualities. If I would be an inventor, I would like to help someone who have the same problems like me, and these items would be efficient and reasonable.
