Child Seat Side Impact Locking With Force-Absorbing Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child seat side impact protection devices are cumbersome to mount and do not effectively reduce impact forces transferred to the child seat.
Innovation Solution
A child seat with a receiving portion configured to couple to a side impact protection device in a positive mechanical locking manner, featuring a locking mechanism that allows for easy attachment and detachment without movable parts, and a force absorbing portion that deforms to distribute and absorb impact forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a side impact protection device is added to a child seat, then impact force reduction is improved, but device complexity and ease of operation deteriorate due to cumbersome mounting
Solution Approach 1:
The side impact protection device is divided into separate components: a receiving portion integrated into the child seat and a detachable protection device portion. This segmentation allows the protection device to be easily attached and removed without complex mounting procedures, resolving the contradiction between reliability and ease of operation.
Solution Approach 2:
The locking mechanism is designed to automatically lock the side impact protection device to the receiving portion upon insertion, without requiring manual operation or complex adjustment. The device self-secures through the automatic locking mechanism, improving ease of operation while maintaining reliable impact protection.
2Reliability
If a locking mechanism is added to secure the side impact protection device, then reliability is improved, but device complexity increases
Solution Approach 1:
The locking mechanism is extracted as a separate, integrated component within the receiving portion of the child seat, rather than being part of the side impact protection device itself. This extraction simplifies the overall device complexity while maintaining secure attachment through the dedicated locking mechanism in the receiving portion.
Solution Approach 2:
The locking mechanism replaces complex mechanical fastening systems with a simpler automatic locking system that secures the side impact protection device through a straightforward insertion and lock engagement, reducing device complexity while ensuring reliable attachment.

AI summary
Disclosed is a child seat for a motor vehicle. The child seat comprises a receiving portion configured to couple to a side impact protection device. Furthermore, the child seat comprises a locking mechanism transferable between a first configuration in which the locking mechanism blocks a detachment of a side impact protection device inserted in or on the receiving portion, and a second configuration in which the side impact protection device can be disengaged from the receiving portion. Further disclosed is a side impact protection device.
