Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing side collision protection mechanisms for child safety seats are complex in structure, making it difficult to efficiently fold them when not in use, thereby compromising convenience and quick deployment during side collision accidents.
Innovation Solution
A side collision protection mechanism with a simple structure, featuring a pivotably connected side collision protection case and a locking element that automatically locks fully when subjected to a side impact force, allowing for quick and convenient folding without the need for unlocking mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism is added to maintain the side collision protection case in extended state, then protection reliability is improved, but device complexity increases
Solution Approach 1:
The locking element automatically locks the side collision protection case in the extended state when subjected to side impact force without requiring external operation. The system self-activates through the force applied during collision, eliminating the need for manual locking mechanisms or additional control systems.
Solution Approach 2:
The locking element transitions between locked and unlocked states dynamically based on the applied force. During side collision, the locking element engages to maintain protection; during normal use, it remains disengaged to allow easy folding. This dynamic behavior resolves the contradiction by providing reliability only when needed.
2Reliability
If the side collision protection case is always locked in extended state, then protection reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The locking mechanism transitions from a static always-locked state to a dynamic state that engages only during side collision. The locking element is designed to activate automatically when side impact force is applied, while remaining easily movable during normal conditions for quick folding and storage.
Solution Approach 2:
The system automatically determines when locking is needed based on the applied force during side collision, eliminating the need for manual intervention. The locking element self-activates during protection events and self-deactivates during normal use, maximizing both reliability and ease of operation.
3Reliability
If the locking element is designed for full locking during impact, then protection reliability is improved, but ease of operation deteriorates due to inability to fold quickly
Solution Approach 1:
The locking element provides full locking engagement during side collision to ensure protection reliability, while during normal use it remains in a partially engaged or disengaged state that allows rapid folding. The dynamic transition between these states enables both full protection when needed and quick deployment when not needed.

AI summary
A side collision protection mechanism includes a side collision protection case pivotally connected to a side region of a child safety seat and a locking element movably set in the side collision protection case and having a locking end detachably locked to the side region. The locking end is fully locked to the side region when the side collision protection case is in an extended state and subjected to a side impact force, or partially locked to the side region when the side collision protection case is in the extended state but not subjected to any side impact force. The side collision protection case can be pushed pivotally relative to the side region to switch from the extended state to a folded state and to release the locking end from its locking to the side region. A child safety seat with the above side collision protection mechanism is also disclosed.
