Many scientists have found that during millions of years of biological evolution, trees always have some ingenious ways to solve the problems they encounter in their survival. People can get some inspiration from trees.

The key to the survival of a population is often reflected in the daily subtle phenomena. In the case of narrow space, organisms will produce folding structures in order to survive.

Japanese origami technology, small pieces of paper not only look pleasing to the eye, but also give people a lot of inspiration. After the paper was wrinkled, diamonds appeared. This crumpled paper is full of this crumpled shape. This folding structure can also exist on any thin object. If you see them on our shirts. All objects with thin structures follow this principle.

In this beautiful folding structure, there is also mathematical correctness. Therefore, the theory of zigzag fold structure based on rhombic structure is correct. The zigzag folding solar absorber designed by this theory saves space and is durable.

A 3-meter-long airplane antenna is stretched and contracted in a box only 2 cm high. This idea comes from the designer's observation of plants.

Canned food won't break, and it absorbs energy while producing pressure during extrusion.

Based on this, automobile designers have deduced the "output rescue method". The problem now is how to absorb energy better. The solution is to skillfully fold the car body.

By observing the shock absorber, it can be clearly seen that it is not broken but squeezed and deformed like a can. This absorbs the energy of the collision.

The folding structure of leaves is a genius design. If you look at a leaf carefully, you will find that every cell is a complex unit. A layer of water wrapped by cell membrane, but this simple structure like water has existed for billions of years.

Radiolarians are tiny protozoa, and their outer cell membrane is embedded with a layer of silica skeleton, which makes them strong and beautiful.

The cellular structure of Barcelona Memorial Church is very similar to that of nature, because they all follow the same rule, that is, to be as strong and light as possible.

No other structure can span such a large area with so little material. The ideal shape is a hemispherical shell structure, and the weight is evenly distributed on the whole structure without dangerous bending and fracture.

This is the building designed by Swiss designer Heinz Gisle, which needs no support and is as strong and attractive as the shell structure.

Shell structure is the most common structure in nature. The curved circle gives them the greatest strength. Snail shells, nut shells and various crustaceans are extremely thin, but because of their shape, they are extremely strong and can provide the greatest protection. There are also some soft materials, such as mushroom shavings, which are also shell-shaped and have petals. The leaves are mostly shell-like structures.

Heinz Giesl's garden provided inspiration for his design.

The initial model of its shell-like structure is used to test durability and durability. In his experiment, he broke the traditional structural design. According to the law that the least material can bear the maximum pressure, different computers can also design countless shapes. Architecture is a traditional field of applying biological forms, and shells are the most primitive and natural dwellings. Perhaps in the future, the circle can replace the stable straight line in the building, so that you can live in a comfortable and safe building structure anywhere.
