Buffer Supporting Leg for Child Safety Seat Impact Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child safety seat supporting legs lack a buffering function, causing direct transmission of impact forces during car crashes or sudden deceleration, which compromises the safety and comfort of children.
Innovation Solution
A buffer supporting leg with a resilient buffering component, such as a thermoplastic polyurethane elastomer or rubber structure, is integrated into the child safety seat assembly to absorb impact forces, featuring a telescopic design and an information device for proper installation, ensuring effective absorption of collision forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a supporting leg is installed on the child safety seat to prevent slipping and falling, then the stability of the child safety seat is improved, but during violent crashes or sudden deceleration, the supporting leg will violently collide with the backrest or panel, causing large impact force to be directly transmitted to the child safety seat, compromising safety
Solution Approach 1:
A buffering component is introduced as an intermediary element between the supporting leg and the child safety seat. This buffering component absorbs and attenuates the impact force generated during violent crashes or sudden deceleration, preventing the large impact force from being directly transmitted to the child safety seat while maintaining the supporting leg's stability function.
Solution Approach 2:
The buffering component is pre-installed on the supporting leg to provide cushioning protection before any collision occurs. This beforehand cushioning ensures that when violent crashes or sudden deceleration happen, the impact force is already attenuated by the buffering component, protecting the child safety seat and occupant from direct impact.
2Strength
If the supporting leg is made rigid to provide strong support, then the supporting function is improved, but the buffering function against impact forces is lost
Solution Approach 1:
The supporting leg is divided into two functional segments: a rigid leg portion that provides strong supporting strength, and a separate buffering component that absorbs impact forces. This segmentation allows each part to perform its specialized function without compromise - the rigid leg provides support while the buffering component handles impact attenuation.
Solution Approach 2:
The buffering component serves as an intermediary between the rigid leg portion and the child safety seat, allowing the leg to maintain its rigid supporting strength while the buffering component absorbs the harmful impact forces, preventing direct transmission to the seat.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The buffering component significantly reduces the impact force transmitted to the child safety seat, enhancing safety and comfort by providing a practical and widely applicable solution for child safety seat assemblies.
Implementation Method 1
the buffering component is a resilient structure
Implementation Method 2
absorbing impact applied to the child safety seat
Implementation Method 3
the friction between the contact surfaces of the first sleeve and the second sleeve is larger than the friction between the contact surfaces of the limiting groove and the limiting protrusion

AI summary
The present invention provides a buffer supporting leg (12) for supporting and buffering a child safety seat (11) and includes a leg potion (122) and a buffering component (121). An upper end of the leg potion (122) is connected to a base (111) of the child safety seat (11). The buffering component (121) is installed on the upper end of the leg portion (122) and for absorbing impact applied to the child safety seat (11). When a large impact force generated by collision acts on the upper end of the leg portion (122), the buffering component (121) can absorb the impact force so as to effectively reduce the impact force transmitted from the upper end of the leg portion (122) to the child safety seat (11), which provides the buffering function and effectively protects a child sitting on the child safety seat (11).
