Resilient Cable Strain Relief for Welding Connection Kink Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional welding equipment cables are prone to kinking or bending at connections, which can damage the welding wire or impede process gas flow.
Innovation Solution
A strain relief mechanism comprising a mounting plate, a support, and a resilient member, which are coupled to the housing of the welding device, allowing the cable to be inserted through a resilient member to prevent kinking or bending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a cable is connected directly to the inlet or outlet of welding equipment, then the connection is simple, but the cable is at risk for kinking or bending which can damage the welding wire or impede process gas flow
Solution Approach 1:
The patent introduces a strain relief mechanism as an intermediary component between the cable and the welding equipment housing. This mechanism includes a resilient member (such as a spring) that mediates the connection, allowing the cable to pass through while preventing excessive bending or kinking. The resilient member absorbs mechanical stress and maintains cable integrity without requiring complex routing, thus resolving the contradiction between simple connection and cable protection.
2Reliability
If a strain relief mechanism is added to protect the cable, then cable integrity is improved, but the device complexity increases
Solution Approach 1:
The patent employs a resilient member, typically a spring or flexible elastic element, as the core component of the strain relief mechanism. This flexible component provides effective cable protection through its inherent elasticity, absorbing stress and preventing kinking without requiring rigid structures or complex assemblies. The simple, flexible design minimizes added complexity while maximizing protective function.
3Stability of the object's composition
If the resilient member is permanently fixed, then the strain relief function is stable, but the adaptability of the mechanism is reduced
Solution Approach 1:
The patent designs the resilient member to be removably mounted rather than permanently fixed, allowing the mechanism to adapt to different cable types, sizes, and installation requirements. The resilient member can be installed or removed as needed, providing dynamic flexibility while maintaining stable strain relief function during operation. This removable mounting approach enables the same basic mechanism to serve multiple purposes and accommodate various configurations.
