College students invented the worry-free chair for the elderly. The reason was that a college student saw that his grandfather had difficulty getting up after sitting down, so he came up with the idea of ??inventing the worry-free chair for the elderly. This invention has been successfully patented. As age increases, the legs and feet of many elderly people become inconvenient and it is difficult to get up and walk. Several students from Guangling College of Yangzhou University invented the "Worry-Free Chair". They also specially brought the invention to nursing homes and invited the elderly to try it out. After trying it, other elderly people also liked it
The invention was recognized by the elderly and the designer was very happy. He said that when he went home this summer, he saw that his grandfather had difficulty getting up after sitting down, so he I came up with a wonderful idea and designed this "worry-free chair". Due to its novel design, convenience and practicality, the chair won the first prize in the 8th Jiangsu College Student Mechanical Innovation Design Competition last month. College students and others have applied for a national patent. After improvements, they will strive for early mass production to help More seniors. After repeated research, they designed the product model
According to the mechanical principle, the elderly will use springs to cushion when they fall slowly, and when standing, the elderly can use a button to release the spring to help them stand. At the same time, they use environmentally friendly materials to make up for the shortcomings of auxiliary seats for the elderly on the market. Of course, the design and production process encounter many difficulties, especially when someone asks: What if the spring under the cushion breaks or gets stuck, and the elderly do not pay attention? If you sit down, the cushion will be tilted on a sloping surface, and the elderly can easily slip off, posing a greater danger. How to solve this safety hazard
This problem has been bothering the team all night. Does the labor-saving chair pop up a warning with a small flag-like sign? That is inconsistent with reality. If you find that the chair is broken, who should you contact? To make repairs, it was a bit of a waste of human resources. After all the proposals were rejected, they came up with the idea of ??fixing a friction pad made of rubber above the mat to prevent the elderly from slipping. Considering the comfort of the elderly when sitting, they only placed The first third of the mat is designed with a non-slip pad.
