Solution Overview
Problem
Conventional side impact protection mechanisms for child car seats have complex structures and difficult operations, which hinder their effectiveness in providing quick and easy protection during lateral collisions.
Innovation Solution
A side impact protection mechanism with a pivotally connected side impact protection block that can switch between unfolded and folded positions, featuring a locking component movable between locking and releasing positions, driven by an operating component for easy transition, and a simple structure that includes a fixing base and elastic components for secure engagement and disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional side impact protection mechanism is used, then lateral collision protection is provided, but the structure becomes complicated and operation becomes difficult
Solution Approach 1:
The side impact protection mechanism is divided into independent functional modules: the protection block that can pivot between folded and unfolded positions, the locking component with locking and releasing positions, and the operating component. This segmentation allows each module to perform its specific function independently, simplifying the overall structure while maintaining reliable lateral collision protection.
Solution Approach 2:
The locking component is extracted as a separate movable element within the protection block, distinct from the main body structure. This extraction allows the locking mechanism to be simplified and integrated smoothly, reducing structural complexity while ensuring reliable engagement and disengagement for effective protection.
2Reliability
If a conventional side impact protection mechanism is used, then lateral collision protection is provided, but operation becomes difficult
Solution Approach 1:
The locking component is designed to automatically engage with the operating component when the protection block pivots to the unfolded position, providing self-locking functionality. This self-service mechanism eliminates the need for complex manual locking operations, making the system easy to operate while maintaining reliable protection during lateral collisions.
Solution Approach 2:
The mechanism transitions from a static locked state to a dynamic unlocked state through simple pivoting motion. The protection block can easily transition between folded and unfolded positions, and the locking component dynamically adjusts its position based on the block's movement, enabling intuitive and easy operation while ensuring reliable protection when deployed.
3Reliability
If the side impact protection block is always in unfolded position, then protection is maximized, but space efficiency and storage become poor
Solution Approach 1:
The protection block is designed to pivot between two dynamic states: folded position for compact storage and unfolded position for maximum protection. This dynamic configuration allows the mechanism to adapt its volume based on operational requirements, providing full lateral collision protection when needed while minimizing space occupation during normal vehicle use or storage.
Solution Approach 2:
The protection mechanism is segmented into a movable protection block that can be independently positioned. This segmentation enables the block to be folded against the vehicle body when protection is not needed, reducing occupied space, while allowing quick deployment to the unfolded position when lateral collision protection is required, thus resolving the contradiction between protection level and space efficiency.

AI summary
A side impact protection mechanism is provided and is disposed on a lateral wing of any component of a child carrier and includes a side impact protection block, a locking component and an operating component. The side impact protection block is switchable between a folded position and an unfolded position, so that the side impact protection block is closely fitted with or at least partially protrudes from the lateral wing. The locking component is switchable between a locking position and a releasing position, so that the side impact protection block is restrained from leaving from the unfolded position or allowed to pivot from the unfolded position to the folded position. The operating component can drive the locking component to move toward the releasing position.
