Child Safety Seat Tether Buffering Against Impact Breakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child safety seats face safety hazards due to deformation or breakage of safety tethers and connections under large impact forces, compromising their ability to maintain the child's position during vehicle collisions.
Innovation Solution
Incorporation of a buffering structure, such as elastic pressing blocks or connecting structures, on the safety tether or seat body to absorb and dissipate tensile forces, preventing deformation or breakage of the safety tether and its connection to the vehicle seat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a safety tether is used to fix the child safety seat to the vehicle seat, then the seat position is stabilized, but under large impact forces the tether may deform or break, compromising safety
Solution Approach 1:
The patent incorporates buffering structures (elastic pressing blocks, foam layers, or telescopic mechanisms) into the safety tether system before impact occurs. These structures are pre-positioned to absorb and dissipate impact forces, preventing the tether from experiencing full tensile stress during collisions. The buffering elements are integrated at strategic points along the tether path to provide progressive force absorption.
Solution Approach 2:
The patent employs materials and mechanisms that change their mechanical parameters under load. The buffering structures transition from a compliant state during normal use to an energy-absorbing state during impact. Elastic materials undergo deformation to absorb energy, while telescopic mechanisms change length to dissipate force, effectively modifying the tether's response characteristics based on impact conditions.
2Strength
If the safety tether is made stronger to resist breakage, then safety under impact improves, but the tether may become too rigid for normal comfort and flexibility
Solution Approach 1:
The safety tether system is divided into multiple functional segments: a strong load-bearing tether component for strength, and separate buffering structures (elastic pressing blocks, foam layers, or telescopic sections) that provide flexibility and comfort. This segmentation allows each component to be optimized independently - the tether maintains high strength while the buffering segments provide the necessary compliance for normal use.
Solution Approach 2:
The buffering structures serve as intermediary elements between the rigid safety tether and the seat body. These intermediaries absorb and distribute forces, preventing direct transmission of rigid forces between the tether and seat structure. The buffering elements mediate the interaction between strong but rigid tether materials and the flexible requirements of the seat system.
