Carrying Rack Hitch Connector With Gap-Eliminating Urging Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional carrying rack connecting devices experience instability and wear due to gaps between connecting rods and mounting rods, leading to deformation and detachment issues during vehicle movement.
Innovation Solution
A carrying rack connecting device featuring an insertion assembly with an urging mechanism, including a pin, driving member, and urging members that securely engage the hitch by moving the urging members outward to abut against the hitch's inner face, eliminating assembly gaps and enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a connecting rod and mounting rod are connected by insertion with a connecting member, then the structure is simple and easy to assemble, but the connection is unstable due to gaps between components
Solution Approach 1:
The patent employs a dynamic urging mechanism where urging members (such as springs) continuously push the connecting rod against the mounting rod, eliminating gaps while maintaining ease of assembly. The urging members are swingably connected and can dynamically adjust to maintain contact pressure during vehicle movement, resolving the contradiction between simple assembly and stable connection.
Solution Approach 2:
The urging mechanism applies preliminary counteracting force through urging members that push the connecting rod against the mounting rod before any gap or instability occurs. This preliminary action prevents the harmful effect of gaps and instability while maintaining the simple insertion-based assembly structure.
2Strength
If adjusting members (bolts) are used to connect the carrying rack, then the connection can be secured, but the adjusting members deform and wear due to wobbling and collision during vehicle movement
Solution Approach 1:
The patent extracts and eliminates the adjusting members (bolts) from the connection structure by using an urging mechanism with urging members that maintain continuous contact between the connecting rod and mounting rod. This removes the source of wobbling and collision damage while maintaining connection strength through the urging force.
Solution Approach 2:
The urging members act as intermediaries between the connecting rod and mounting rod, maintaining stable contact and distributing forces evenly. This intermediary mechanism eliminates the direct wobbling and collision that would otherwise damage the adjusting members, while still providing secure connection.
3Ease of repair
If the through hole is enlarged to accommodate worn adjusting members, then the adjusting member can remain in use, but the connection becomes even less stable
Solution Approach 1:
The patent removes the adjusting members entirely from the connection structure, replacing them with an urging mechanism that maintains stable contact without through holes. This eliminates the need to enlarge holes for worn members while maintaining connection stability through continuous urging force.
