Segmented Seat Cushion Support for Child Impact Energy Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child safety seat support structures fail to provide adequate protection during impacts as they cannot deform sufficiently to absorb collision energy, while also requiring a simple mechanism for manufacturing and cost-effectiveness.
Innovation Solution
A support structure with a buffer portion divided into multiple connected blocks by slits, allowing for deformation under impact, integrated into a frame structure with varying block connections and materials for enhanced support and buffering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the support structure uses a solid buffer portion, then it provides good support under normal conditions, but it cannot deform sufficiently to absorb collision energy during impact
Solution Approach 1:
The buffer portion is divided into multiple buffer blocks through first slits, allowing each block to deform independently during impact while maintaining overall structural integrity through connections at the back surface. This segmentation enables sufficient deformation for energy absorption while preserving support functionality.
Solution Approach 2:
The buffer blocks are designed to be movable relative to each other through the slits, transforming the rigid solid structure into a dynamic system that can adapt its shape during collision to maximize energy absorption while maintaining support under normal conditions.
2Object-affected harmful factors
If the support structure divides the buffer portion into multiple separate blocks, then it can deform more during impact, but it increases manufacturing complexity
Solution Approach 1:
Multiple buffer blocks are connected at their back surfaces to form an integrated buffer portion, reducing manufacturing complexity compared to completely separate blocks while maintaining the ability to deform independently during impact through the slit connections.
Solution Approach 2:
The buffer portion is segmented into connected blocks rather than being completely separate, achieving a balance between deformation capability and manufacturing simplicity by maintaining connections at the back surface while allowing movement through the slits.
3Object-affected harmful factors
If the support structure uses a complex mechanism to enhance protection, then it can provide better collision energy absorption, but it increases manufacturing complexity and cost
Solution Approach 1:
The buffer portion is divided into connected buffer blocks through simple slits, creating a deformation-capable structure that absorbs collision energy without requiring complex mechanisms, thereby maintaining ease of manufacture while enhancing protection.
Solution Approach 2:
The structure changes its physical parameters (shape, volume) during impact through the movement of buffer blocks relative to each other, enabling energy absorption through geometric deformation rather than complex mechanical mechanisms.
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 support structure effectively disperses impact force, providing better protection for a child's back and buttocks by allowing deformation in multiple directions while maintaining support during normal conditions, thus enhancing safety and reducing manufacturing complexity.
Implementation Method 1
the buffer portion includes a plurality of buffer blocks provided adjacent to each other; where at least one first slit is provided on a support surface of the buffer portion, the first slit divides the buffer portion into the plurality of the buffer blocks
Implementation Method 2
the protective effect of the seat cushion structures is not good when the vehicle is subjected to impact. Especially when the seat cushion structure is impacted, it cannot deform enough at the child's back and buttocks, thereby failing to provide better protection for the child's back and buttocks
