Multi-Axis Ball-and-Socket Chain Link for Drag Chains
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy guiding chains face challenges in maintaining the pivotability of transverse webs, which can lead to increased load on joint connections during line insertion or removal, potentially causing damage, especially in limited installation spaces.
Innovation Solution
A chain link design featuring a multi-axis articulated connection, specifically a ball-and-socket joint, that allows the transverse web to pivot freely while maintaining a secure hold, with a releasable connection that requires minimal force to open, preventing damage during line access or maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional single-axis connection is used for the transverse web, then the structure is simple, but the pivotability is limited and load concentration occurs during line insertion or removal
Solution Approach 1:
The patent applies a ball-and-socket joint connection where the transverse web has a spherical head that fits into a socket on the chain link. This spherical geometry enables multi-axis rotation and pivoting in multiple directions, significantly improving the pivotability of the transverse web compared to conventional single-axis connections, while maintaining a relatively simple structural design.
2Reliability
If the transverse web is tightly secured to prevent opening, then retention is strong, but it becomes difficult to release for line access
Solution Approach 1:
The ball-and-socket joint connection provides dynamic retention - the spherical head fits tightly into the socket under normal operating conditions to prevent unintended opening, ensuring reliable retention. However, when force is applied in the correct direction (pulling the transverse web away from the chain link), the connection can be easily released by overcoming the retaining force, allowing convenient access for line insertion or removal.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The multi-axis articulated connection enhances the pivotability of the transverse web, reducing the risk of damage during line insertion or removal and ensuring secure retention of hoses or cables, even under hydraulic pressure.
Implementation Method 1
the multi-axis articulated connection is achieved in that it is designed as a ball-and-socket joint connection
