A clever inventor is someone who creates new devices or processes to solve problems or improve existing solutions. They often use their knowledge of science and technology to design innovative products. Famous examples of clever inventors include Thomas Edison, who developed the electric light bulb, and Nikola Tesla, known for his work on alternating current. Inventors typically go through a process of brainstorming, prototyping, and testing their ideas. They may work alone or collaborate with others, including engineers and designers. Successful inventions can lead to patents, which protect the inventor's rights and allow them to profit from their creations.
