1. Find an empty paper box (with a certain thickness, preferably a box type), then punch holes around it, sew the eggs with cloth, leave holes around the rope, then use a thin rope to pass through the box, enter the box, and pull the eggs up (so that the eggs will hang in the paper box, but don't pull them too tightly).

In this way, if it falls from the sky, the air resistance of the carton itself and the suspension will ensure that it will not be broken.

2. Packaging type:

The outer packaging type is to wrap the eggs tightly with more shock-absorbing materials. Such as foam, cotton, various filling materials, etc. Through the buffering effect of these substances, the purpose of protecting eggs is achieved.

3. Tumbler type:

The tumbler type means that the whole device is like a tumbler, and the center of gravity is lowered as much as possible to keep the device in a stable state when falling and ensure that one side always touches the ground. Then the protection work only needs to be done on this side, saving materials.

This scheme fully considers the air tumbling phenomenon that may occur in the previous scheme and is formed after improvement.

4, polyhedron type:

The polyhedron type is to make the whole device into a polyhedron, and fix the egg in the center of the polyhedron with a strong rope, so that the whole egg is suspended. After the device lands, no matter which side it lands, the egg will not land, and the egg will be intact.

This scheme does not need additional materials, only needs to make a polyhedral skeleton and several lines, which is extremely economical in materials and greatly reduces the weight. Because the air resistance is small and the stability is good. However, this scheme also has a great disadvantage that the polyhedron is not easy to bind and the firmness is not high. After landing, it may fall apart and the eggs are in jeopardy.

5, double balloon type:

Double balloon, that is, put eggs in a balloon, fill it with a certain amount of air, put another balloon outside, and fill it with a proper amount of air. In this way, an air cushion will be formed between the two balloons to protect the eggs from the impact of the ground.

6, salt water type:

Salt water type, is to use a very strong sodium chloride solution, so that eggs float on it, after landing, salt water as a buffer material to ensure that eggs are not broken. The scheme is novel and unique, with salt water as buffer, high safety, little influence by air resistance and high precision.

However, the device is not easy to control. If the device rolls in the air and the salt water spills out, it will not play a protective role. So make sure that the center of gravity of the equipment is stable and as low as possible. The weight of this device cannot be ignored. After all, salt water is much denser than foam.

7, straw group type:

Straw assembly: several straws are tied together to make a straw group, and several groups of straws are formed into a pyramid shape with eggs in the middle and fixed with adhesive tape. Because the straw is hollow, it can play a buffering role. ?

Suggestion:

1, eggshell reinforcement: first, wrap the eggs tightly with transparent tape several times, and the requirements must be important. This has three advantages: a. Thickening the eggshell; B. increase the tensile strength of the outer surface of the eggshell. C. reduce the brittleness of eggshells.

2. Egg outer cushion: wrapped with sponge, with low sea density and high impact resistance, it is a superior material.

3. Reduce the impact force: put a parachute on the whole device to increase air resistance and reduce the impact force. The parachute decelerated in the air. Use plastic foam and cotton as a buffer when landing.
