Child Safety Seat Impact-Absorbing Base for Collision Force Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional child safety seats have a complex structure, leading to high costs and low safety performance in reducing impact forces during collisions.
Innovation Solution
A child safety seat with a simple structure featuring an impact absorbing mechanism, including protruding parts on the bottom surface that reduce impact force by creating a buffer space and minimizing contact area with the car seat, thereby enhancing energy absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional child safety seat uses a complicated structure, then it may provide basic protection, but it results in high cost and low safety performance in reducing impact force
Solution Approach 1:
The seat bottom surface is segmented into multiple protruding parts distributed across the surface. Each protruding part independently contacts the car seat to create buffer spaces, distributing the impact force across multiple contact points rather than a single large contact area, thereby improving impact force reduction without requiring complex overall structure
Solution Approach 2:
The protruding parts are strategically positioned at specific locations on the seat bottom surface where they protrude a specific distance to create optimal buffer spaces. This local modification of the seat structure at key impact zones provides effective impact force reduction while maintaining simplicity of the overall seat design
2Reliability
If a traditional child safety seat uses a complicated structure, then it may provide basic protection, but it results in high manufacturing cost
Solution Approach 1:
The seat is manufactured as an integrated structure with protruding parts formed directly as part of the seat molding process. This segmentation of function rather than physical separation into multiple components simplifies manufacturing and reduces assembly steps, thereby lowering production costs while maintaining safety performance
Solution Approach 2:
The protruding parts serve multiple functions simultaneously: they create buffer spaces for impact absorption, reduce contact area with the car seat, and are integrated into the seat structure during manufacturing. This multi-functionality eliminates the need for separate impact-absorbing components, reducing part count and manufacturing complexity

AI summary
The present invention provides a child safety seat. The child safety seat comprises a seat body and an impact absorbing mechanism. The seat body comprises a backrest part and a seat part, and the impact absorbing mechanism is connected to a bottom surface of the seat part. The impact absorbing mechanism comprises at least two protruding parts positioned on a rear part of the impact absorbing mechanism and protruding from the bottom surface of the seat part. The rear part is near the backrest part of the seat body. When the child safety seat is positioned on a car seat and contacts the car seat, the protruding parts are utilized for reducing impact force received from the car seat when the child safety seat encounters an impact.
