Air-Filled Shock Absorption Structure for Multi-Directional Collisions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shock absorption systems installed on vehicles, ships, and road facilities are ineffective in absorbing impact forces consistently across different collision directions and often result in significant damage due to their weight, which increases fuel inefficiency and fails to mitigate secondary accidents.
Innovation Solution
A shock absorption structure filled with air and reinforced with fiber threads and aramid fibers, equipped with adjustable air inlets and outlets, and a burst inducing part, which uses a tension line to wrap around the damaging object upon impact, allowing for directional independence in impact absorption and minimizing damage through controlled air discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional shock absorbers are installed to absorb impact force, then damage to vehicle and passengers is reduced, but the shock absorber cannot reduce damage caused by secondary or tertiary accidents after internal air is completely discharged
Solution Approach 1:
The patent changes the physical state parameters of the shock absorption medium from gas (air) to liquid (water). Liquid is incompressible and does not discharge like gas, allowing the shock absorber to maintain protective function continuously. The liquid-filled configuration enables the shock absorber to absorb repeated impacts without losing its cushioning capability, resolving the reliability issue of conventional air-filled shock absorbers that become ineffective after air discharge.
2Reliability
If conventional shock absorbers are used to absorb impact force, then shock protection is provided, but there is significant difference in impact force absorption depending on collision direction
Solution Approach 1:
The patent designs the shock absorber with a spherical geometry and internal liquid circulation system that provides universal shock absorption capability across all collision directions. The liquid medium can flow and redistribute pressure uniformly in any direction of impact, making the shock absorber equally effective whether struck from front, rear, side, or any angle, thus achieving multi-directional protection coverage.
Solution Approach 2:
The spherical shape of the shock absorber body allows uniform distribution of impact forces from any direction. The curved surface and internal liquid circulation path ensure that regardless of collision angle, the liquid can effectively absorb and dissipate energy, providing consistent protection performance across all orientations and eliminating the directional limitations of conventional shock absorbers.
3Reliability
If conventional shock absorbers are installed to protect against collisions, then impact force is absorbed, but the shock absorber has significant weight requiring many installation parts
Solution Approach 1:
The patent employs a flexible membrane structure to contain the liquid shock absorption medium. This thin-film approach replaces heavy rigid metal housings with lightweight flexible material that can still contain the liquid under pressure and transmit the shock absorption effect. The flexible shell significantly reduces the weight of the shock absorber while maintaining its protective function, eliminating the need for heavy installation components.
4Reliability
If conventional shock absorbers are installed on vehicles, then collision protection is provided, but fuel efficiency is significantly reduced due to increased weight
Solution Approach 1:
By replacing heavy rigid structures with flexible thin-film membranes, the shock absorber weight is dramatically reduced. This weight reduction directly improves vehicle fuel efficiency while maintaining the collision protection function, as the flexible membrane is sufficient to contain the liquid medium and transmit the shock absorption effect without requiring heavy metal housings and mounting components.
