Child Seat Wing Barrier Lock for Safe Child Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional safety mechanisms for child seat assemblies are complex to mount and lack a barrier to prevent children from falling out when the mechanism is released, posing a safety risk.
Innovation Solution
A safety device comprising a bracket, pivotally connected first and second wings, and a locking piece that engages with the wings to prevent rotation and maintain a horizontal position, with a flexible piece and studs for secure attachment, and a locking mechanism that allows synchronized rotation of the wings for easy child removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional safety mechanism is used to allow easy child removal, then the child can be easily taken out of the seat assembly, but the mounting structure becomes very complicated
Solution Approach 1:
The safety mechanism is divided into separate functional components: a pivotally connected wing assembly that provides the release function, and a simple bracket for mounting. This segmentation allows the complex release mechanism to be isolated from the mounting structure, simplifying the overall assembly while maintaining ease of child removal.
Solution Approach 2:
The safety mechanism is extracted as a separate, pivotally connected component that can rotate independently from the mounting bracket. This extraction allows the mounting structure to remain simple while the safety mechanism provides the necessary child removal function through its pivotal motion.
2Ease of operation
If the safety mechanism is pivotally rotated to a position under the seat assembly for easy removal, then the child can be easily taken out, but there is no barrier to prevent the child from falling out
Solution Approach 1:
The wing assembly is designed to be dynamically pivotally connected to the bracket, allowing it to rotate between a locked position (providing barrier) and an unlocked position (allowing removal). This dynamic connection enables the structure to adapt its configuration based on operational needs, maintaining safety during normal use while enabling easy removal when required.
Solution Approach 2:
The pivotal connection is designed to maintain the wing assembly in a barrier-providing position during normal operation, preliminarily preventing child fall-out. The mechanism only allows rotation to the removed position when intentionally activated, ensuring safety is maintained until the release action is deliberately performed.
3Reliability
If a locking piece is used to engage with wings to prevent rotation, then the barrier function is maintained, but the structure becomes more complex
Solution Approach 1:
The locking function is merged with the pivotal connection structure itself. The pivot connection inherently provides both the rotational capability and the locking function through its geometric configuration, eliminating the need for separate complex locking mechanisms while maintaining reliable wing rotation prevention.

AI summary
A safety device used in combination with a child seat assembly is provided to solve the problems about complicated structure and risk for the children. The safety device includes a bracket, a first wing and a second wing pivotally connected to the head portion of the bracket, a flexible piece cooperating the first and second wings, a locking piece releasably engaged with the first and second wings. When one of the wings is pivotally rotated, both of the wings will be synchronously rotated to a vertical or horizontal state.
