A technological innovation system is like a big machine that helps make new inventions and ideas. It's made up of lots of different parts and people, all working together to create new and better things.
Imagine that the machine is a big puzzle with lots of small pieces. One piece might be scientists who work in labs and come up with new ideas for things like medicine or electronics. Another piece might be engineers who figure out how to build these new things and make them work properly. There are also businessmen who invest money in these new ideas, and government officials who make rules and regulations to make sure everything is safe and fair.
All these different pieces work together to create new inventions and improve existing ones. For example, if someone has an idea for a new type of car, they would need scientists to figure out what kind of fuel it should use and how it can be made more environmentally friendly. They would also need engineers to design the car and figure out how to make it run smoothly, and businessmen to invest money in the project and market the car to the public.
The technological innovation system is constantly changing and improving, just like the puzzle pieces in the machine are constantly shifting around. As new ideas are discovered and new inventions are made, more pieces are added to the puzzle and the machine becomes even more complex and efficient.
In summary, the technological innovation system is a big machine made up of different parts and people who work together to create new and better ideas and inventions. It's like a puzzle that's always changing and improving as new pieces are added.
