Rotary Top Rod Locking Structure for Foldable Safety Seats
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional child car seats are unstable due to separate cradle and base structures, leading to difficulties in transportation and space efficiency.
Innovation Solution
A rotary top rod system for a safety seat, featuring a rotatable top rod body with a locking assembly that can be fixed in use for stability and folded for space-saving transport, comprising rotating arms, a mounting rod, and a locking mechanism with a clamping and elastic component for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the base is extended with support rods or support bars to improve stability, then the stability of the safety seat is improved, but the device size increases and becomes difficult to transport
Solution Approach 1:
The top rod is designed as a rotatable component that can dynamically change its position between an extended support state during use and a folded state for transport. The rotation assembly allows the top rod to be positioned at different angles, providing stability when needed and reducing volume when not in use.
Solution Approach 2:
The top rod can be folded and stored within or alongside the safety seat structure when not in use, effectively nesting the support component within the overall device volume, thereby reducing the space required for transportation without compromising stability during use.
2Stability of the object's composition
If the top rod is made fixed to ensure stability, then the stability is improved, but the ease of operation for transportation is worsened
Solution Approach 1:
The top rod transitions from a fixed structure to a dynamic, rotatable structure that can be easily repositioned. The rotation assembly with locking mechanism allows the top rod to be quickly adjusted between extended and folded positions, making transportation convenient while maintaining stability during use.
Solution Approach 2:
The locking assembly is designed to automatically engage and lock the top rod in its extended position during use, and can be easily released for folding. This self-locking mechanism ensures stability without requiring constant manual intervention, while still allowing easy operation when transportation is needed.
