I realized one day when I was designing a new endoscope in 2007, that “to invent something new, it doesn’t require talent, but skills”. I came up with four skill structures that make up an invention, 1. Addition, 2. Subtraction, 3. Multiplication, and 4. Division. If these concepts are utilized effectively, the possibilities of innovation are endless. The future of this nation and the whole world is shaped by the minds of the next generations. Let me show you the wonders of invention.
