Solution Overview
Problem
Conventional side impact protection mechanisms in 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 and a locking component that can switch between locking and releasing positions, allowing easy transition between unfolded and folded positions using an operating component for simple and efficient deployment.
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 side impact protection block that can pivot independently, the locking component with distinct locking and releasing positions, and the operating component. This segmentation allows each part to perform its specific function simply, resolving the contradiction between providing reliable protection and maintaining structural simplicity.
Solution Approach 2:
Instead of using a complex multi-stage locking system, the patent inverts the approach by using a simple pivotable block with a straightforward locking component that can be easily engaged or disengaged. The locking component switches between locking and releasing positions through a simple mechanical action, eliminating the need for complicated mechanisms while maintaining 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 essential function of lateral collision protection is extracted and concentrated in the side impact protection block, which pivots to provide protection. The operating component is designed to directly control the locking component without intermediate mechanisms, allowing users to easily deploy or retract the protection block with a simple action, thus improving ease of operation while maintaining reliable protection.
Solution Approach 2:
The side impact protection block is designed to be pivotable rather than fixed, allowing it to dynamically adjust between a folded position (retracted) and an unfolded position (extended for protection). This dynamic design enables easy operation for deployment and retraction while ensuring reliable protection when activated, resolving the contradiction between protection effectiveness and operational ease.
3Ease of operation
If the side impact protection block is made pivotable for easy deployment, then operation becomes simple, but the locking mechanism must be reliable to maintain position
Solution Approach 1:
The locking component is designed to automatically engage with the side impact protection block when the block reaches its unfolded position, providing self-locking functionality. This self-service mechanism ensures reliable positioning without requiring complex manual locking operations, thus maintaining both operational simplicity and locking reliability.

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.
