Sliding Car Seat Base with Energy Absorbing Material
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child car seats lack effective protection for the seat itself during collisions, as the seat tends to wobble relative to the base due to inertia, leading to potential deformation or breakage at the connected location.
Innovation Solution
An energy and shock absorbing device is introduced, featuring a slidably connected seat and base with energy absorbing material between them, which compresses and deforms to provide buffering and shock absorption when a collision occurs, protecting both the seat and the child.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the seat is fixedly connected to the base, then the structural strength is improved, but the shock absorption capability deteriorates
Solution Approach 1:
The patent transforms the fixed connection between seat and base into a dynamic slidable connection. The seat can slide along a predetermined path on the base, allowing the structure to adapt dynamically during collision by converting kinetic energy into sliding motion, thereby resolving the contradiction between structural strength and shock absorption capability
Solution Approach 2:
The patent divides the connection system into separate functional components: a sliding block on the seat, a guide structure on the base, and energy absorbing material positioned along the sliding path. This segmentation allows each component to perform its specific function - the sliding mechanism provides motion freedom while the energy absorbing material provides shock protection
2Stability of the object's composition
If the seat is fixedly connected to the base, then the structural stability is improved, but the energy absorption capability deteriorates
Solution Approach 1:
The patent introduces energy absorbing material as an intermediary substance between the sliding seat and the base. This material acts as a mediator that dissipates collision energy through deformation, protecting both the seat structure and the child from shock impacts while maintaining structural stability through the guided sliding mechanism
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 solution effectively absorbs shock and buffers the seat during collisions, preventing deformation and breakage, thereby enhancing the safety and durability of the child car seat.
Implementation Method 1
Energy absorbing material is arranged between the limit block and the seat, and is compressed to deform when the seat slides towards the limit block
Implementation Method 2
When a car encounters a collision or emergency brake, the seat moves relative to the base due to inertia

AI summary
An energy and shock absorbing device for a child car seat comprises a seat (1), and a base (2) positioned below the seat (1) and used for supporting the seat (1), the seat (1) being slidably arranged on the base (2). A limit block (22) is formed on the base (2) and located in front of the seat (1) in a path along which the seat (1) slides relative to the base (2). Energy absorbing material (4) is arranged between the limit block (22) and the seat (1), and is compressed to deform when the seat (1) slides towards the limit block (22). When a car encounters a collision or emergency brake, the seat (1) moves relative to the base (2) due to inertia, and the energy absorbing material (4) is squeezed to deform so as to provide a buffering and shock absorbing action. The word “front” described here and elsewhere is defined according to the moving direction of the seat (1), that is, the direction along which the seat (1) slides relative to the base (2) when a car collision occurs is front, and conversely, the direction opposite to front is rear.
