The invention of the old man originated from taking care of his old father who was paralyzed in bed more than 20 years ago. In the process of serving his father every day, the old man came up with the idea of inventing an automatic turn-over bed. Since then, the old man has been out of control on the road of invention, and has invented 3 1 artifact for many years.
First, the old-age artifact is very useful for helping the elderly solve problems. When the elderly get old, their physical fitness and flexibility are not as good as before. Under such circumstances, many diseases have gradually become prominent. From going up and down stairs, going to the toilet to sleeping and turning over, these simple actions are very difficult for the elderly.
The old man studied and invented the inconvenience of old age. Using stair climbing machine can solve the problem of the elderly going upstairs and downstairs; The use of automatic turn-over bed can help the elderly turn over smoothly; There is also a lifting seat when going to the toilet, which can solve the problem of weak knees of the elderly.
Second, being able to put into production, use and promotion is the gospel of the elderly. After these inventions are invented, if they cannot be tested and finally mass-produced, they will not bring good news to the lives of the elderly. If you want to put the invention into practice, you need to stand the test of practice and become a product for sale, which will really bring changes to the lives of the elderly.
I think this result is the original intention of uncle's invention and what he hopes in his heart. There is still a long way to go from invention to market. This is also a reason why it is easy to invent and difficult to make a profit.
Whether it can be popularized in the end or not, the spirit and quality possessed by uncle are worth learning and enterprising.
