Multi-Position Cable Tray Hinge for Horizontal and Vertical Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection devices for cable trays allow articulation only in a single plane, either horizontal or vertical, leading to stock and supply issues based on demand for specific hinge types.
Innovation Solution
A multi-position hinge system enabling angular connection in both horizontal and vertical planes, with interchangeable coupling means for real-time adjustment, comprising a pin, first and second members, and intermediate attachment members with harpoon-shaped extensions and screw holes for secure attachment to cable trays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If connection devices are designed for single-plane articulation (horizontal or vertical), then the hinge structure is simple and easy to manufacture, but the adaptability is limited and stock management becomes complex due to multiple hinge types needed
Solution Approach 1:
The hinge device is designed to perform multiple functions by enabling articulation in both horizontal and vertical planes using the same hinge structure. The first and second members can be articulated in either plane, allowing a single hinge type to replace multiple specialized hinge types, thereby improving adaptability while maintaining structural simplicity
Solution Approach 2:
The hinge incorporates dynamic positioning capability through the intermediate attachment members that can be selectively coupled to different members. This allows the articulation plane to be changed dynamically based on installation requirements, transforming a static single-plane hinge into a dynamic multi-plane solution without increasing fundamental structural complexity
2Adaptability or versatility
If multiple types of hinges are maintained in stock for different planes, then the adaptability to meet various demands is improved, but the stock management complexity and supply chain burden increase
Solution Approach 1:
By designing a universal hinge that can function in both horizontal and vertical planes, the system reduces inventory variety from multiple specialized hinge types to a single multi-functional hinge type. This eliminates the need to maintain separate stock for different plane requirements while maintaining the ability to meet diverse installation demands
Solution Approach 2:
The hinge system allows change in operational parameters (articulation plane) without changing the physical hinge itself. By modifying which members are coupled to which trays, the same hinge can adapt to different plane requirements, reducing inventory needs while maintaining demand response flexibility
3Ease of operation
If fixed-plane hinges are used, then the manufacturing process is simple and cost-effective, but the ease of operation is reduced as operators cannot adjust connection type in real-time
Solution Approach 1:
The hinge system incorporates dynamic reconfigurability through intermediate attachment members that can be selectively coupled to different members (first member, second member, or neither). This allows operators to adjust the connection type in real-time based on installation requirements, improving ease of operation while maintaining relatively simple manufacturing processes
Solution Approach 2:
The hinge is segmented into distinct components (first member, second member, intermediate attachment members) that can be independently coupled and decoupled. This modular segmentation enables flexible reconfiguration during installation without requiring complex manufacturing processes, balancing ease of operation with manufacturing simplicity
