Sliding Support Leg Assembly for Child Seat Base Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child safety seat support legs are complex in structure, heavy, cumbersome to assemble, and costly due to their design, which includes multiple parts and square tube connections.
Innovation Solution
A simplified support leg design featuring a slidably connected connector and stopper system that eliminates the need for square tube connections, incorporating a sliding groove, reinforcement plates, and a folding mechanism to reduce weight and production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the existing support leg uses two square tubes for mounting, then the connection stability is improved, but the structure becomes complex and the weight increases
Solution Approach 1:
The patent extracts and eliminates the square tube components from the support leg structure, replacing them with a simplified connector that directly mounts to the base through a sliding groove, thereby reducing structural complexity while maintaining connection stability through the stopper mechanism
Solution Approach 2:
The patent merges the mounting function and the support function into a single integrated connector assembly that slides into the base and is secured by a stopper, eliminating the need for separate square tube components and simplifying the overall structure
2Reliability
If the existing support leg uses two square tubes for mounting, then the connection stability is improved, but the production cost increases
Solution Approach 1:
The patent removes the expensive square tube components and replaces them with simpler, cheaper alternatives such as a sliding plate connector and a stopper mechanism, thereby reducing production cost while maintaining adequate connection stability
Solution Approach 2:
The patent employs simpler, more cost-effective materials and components such as the sliding plate and stopper instead of expensive square tubes, achieving the same functional outcome at lower production cost
3Reliability
If the existing support leg uses two square tubes for mounting, then the connection stability is improved, but the assembly becomes cumbersome
Solution Approach 1:
The patent introduces a dynamic sliding mechanism where the connector can slide into the base along a sliding groove and is then secured by a stopper, allowing for easy assembly and disassembly while maintaining connection stability during use
Solution Approach 2:
The patent segments the support leg into modular components (connector, sliding groove, stopper) that can be easily assembled and disassembled independently, greatly improving assembly convenience compared to the integrated square tube structure
4Adaptability or versatility
If the connector can extend out of the sliding groove, then the adjustment range is improved, but the risk of separation increases
Solution Approach 1:
The patent creates a dynamic system where the connector can slide in and out of the base along the sliding groove for adjustment, while the stopper mechanism dynamically engages to prevent excessive separation, thus providing both adjustability and connection stability
Solution Approach 2:
The patent allows the position parameter of the connector to be changed by sliding it in and out of the base, while the stopper mechanism maintains a maximum limit parameter to prevent separation, achieving both adjustment range and connection stability
