Model of people who can survive in traffic accidents

Graham has no neck, flattened face, thicker skin, larger skull, more flexible leg joints, helping to protect the body from injury when a traffic accident occurs.

Graham is a contemporary sculpture by David Logan , an accident investigation specialist at Monash University and Christian Kenfield, Royal Melbourne hospital orthopedic surgeon and Patricia Piccinini, sculptor, and perfect each other.

This is a work that is located in the Towards Zero traffic safety campaign of Victoria, Australia. The work depicts the body structure that can survive in car accidents.

" Cars grow much faster than human growth. Graham helps us understand, why improve all aspects of the transportation system to protect ourselves," said the head of the organizing committee. translated, Joe Calafiore said.

" Graham's brain is similar to our brains, but the skull is larger, contains more fluid and more ligaments to protect the brain when a collision occurs ," said Patricia, female Graham artist.

Graham's skull is much larger than the human skull. It is like a helmet, increasing the ability to absorb impact. The force regions slow the momentum forward, and the force continues to damage the brain.

Human face is a subtle combination of bone, muscle and cartilage. When an accident occurs, the face is often injured by hitting the steering wheel, dashboard, windshield, even broken glass. These items can cause minor wounds such as severe skin rupture such as fractures.

Graham's face was flattened, his nose was flat, and fatty tissue around his cheekbones absorbed the impact. The ears also recede, protected by a large skull structure and neck guard.

When the car suddenly stopped, many inertial parts still rushed forward, including the head. In a normal person, the slender neck without enough strength keeps the head from rushing forward. More dangerous, the spinal cord in the neck may be bent or stretched excessively, causing it to break, causing serious injuries such as paralysis of the legs or limbs.

To solve this problem, designers removed Graham's neck.The rib , a kind of protective frame, is extended towards the skull, like a second protective layer for Graham's head when a collision occurs.

Normally, skin damage is not life-threatening, but it also damages the flesh, nerves and causes pain to the person who has an accident.

Graham has a thicker, harder skin than normal people, not easily scratched. The skin around the area of ​​the arms, elbows, hands - the areas that often stretch instinctively when falling, are also thicker.

Some areas of the body control force better, like ribs. Ribs are the best protective frame for human organs. They are the first line of defense when a collision occurs.

Safety belts are designed to take advantage of the strength of the ribs, helping us to bear the impact. That's why most seat belts squeeze through three points of ribs, sternum and pelvis. When a collision occurs, it will spread the impact force throughout the ribs to absorb the impact but if the force is too large and sudden, the rib will break.

The most ideal way to limit this is to slow down the force, but not as suddenly as when a car accident occurs. Graham is designed with stronger ribs that better protect him from accidents. The large chest, the inside of which has a follicle between the ribs acts as an airbag, absorbs the force acting on the ribs, protects the heart and other vital organs in the upper body.

Normally, when a pedestrian is hit by a car, the knee will be the first part to be hurt. Depending on the force, the ligaments can also be stretched excessively, even severely. In addition, the knee only bends in one direction, which is why it is the easiest to break.
Therefore, Graham's knee is designed to be able to rotate in all directions, the knee is also supported with ligaments, allowing the knee to bend and be more flexible.

For pedestrians, there are many factors that affect the severity of injuries such as vehicle size, height, speed and crash angle. There are many serious injuries in the legs.

In fact, damage to the legs, feet and ankles can cause long-term physical weakness because we depend on them to move everyday.

The leg bone is the least protected part of the body, only a thin layer of skin covers it.

Graham's feet are designed like animal paws, with swivel joints that allow him to jump off the road as fast as attaching a spring to his leg.

The work is on display at the Victoria Library until September 8 and will be exhibited throughout Australia.Video: Guardian
