This design was inspired by the shape of honeycomb, in addition, high toughness and lightweight materials are used.The concept of this design is to set the honeycomb-shaped construction to a car's bumper.When a traffic collision happens ,the hexagonal construction of a honeycomb can deliver the forces to two directions and so on, so that the stress surface expands and the forces will be weaken. During the process, this kind of material with high toughness will be deformed , as a result, certain counter forces will be generated to reduce shock and injuries, achieving buffering effect.
