What are the applications of modern ergonomics in ancient stools and chairs?

The main applications are as follows:

1.It is applied to deal with the relationship between human, machine and environment.

Ergonomics is the study of the interaction between people and other components. Although as a discipline, ergonomics was born between 1945 and 1960. After 1980, it has developed into a complete discipline system, and it has only a history of fifty or sixty years, but in fact, the principle of ergonomics has been used by human beings in the practice of manufacturing goods thousands of years ago, and the seat of the Ming Dynasty in China is one of the models.

2.Apply to rigorous proportional relationships.

For example, the proportion of parts and parts of Ming Dynasty furniture, the proportion of decoration and the overall shape, are very uniform and coordinated. Furniture, such as chairs and tables, upper and lower parts, legs, strokes, backs, heads, heights, lengths, thicknesses, widths, all of which are perfectly balanced and coordinated. And it is extremely consistent with the performance requirements, without the slightest cumbersomeness, giving people a sense of the overall combination of points, lines and surfaces.

The lines of the various sections are in a straight and beautiful position. Soft and soft, the lines are stiff but not weak, showing a delicate, concise, elegant, and atmospheric beauty.

3.Apply to the human body.

After all, there is a big difference between sitting cross-legged and sitting on high feet. In the Tang Dynasty, it used to be a low seat, and then it was sat on with tall furniture, and the tall seat reached its peak by the Ming Dynasty. It can be seen from the chair of the Ming Dynasty that people's life mode has officially changed from sitting on the ground to the way of sitting with the feet down, so whether the seat is comfortable has become particularly important, the height of the seat and the size of the seat surface, and even the design of the backrest need to be repeatedly scrutinized, such as the chair of the Ming Dynasty, looking at the front, the armrest, the backrest and other components are thinner, and the bending arc is large, which expands the sitting space, so that people can sit up at will, in line with the needs of the human sitting posture; Viewed from the side, the curved curve of the backrest resembles the curves of the human body from the back to the corners, all of which are derived from the mannequin.

The parts, parts, and copper parts that come into contact with the human body are all round and soft, giving people a very comfortable feeling. When furnishing, it is full of artistic harmony and beauty, and can actively integrate into the environment, so that the design can make the best use of things on the one hand; On the other hand, it is more comfortable and convenient to use.

It has a particularly high application, because such technology makes the stability of the stool higher and higher, can make the appearance of the stool higher and higher, can bring people more and more high-quality service, can reduce muscle wear, and can allow people to ensure a natural sitting posture.

The application is to make tables, chairs and benches, to make beds, to make pillows, to make dining tables, to make reclining chairs, and to make soft couches.

In the past two days, this aspect has also been studied.
