Multi-Position Cable Tray Hinge With Reconfigurable Articulation Planes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection devices for cable trays only allow articulation in a single plane, either horizontal or vertical, leading to stock and supply issues based on demand for specific types of hinges.
Innovation Solution
A multi-position hinge with a pin defining a geometric articulation axis, coupled with intermediate attachment members featuring housing and screw-based coupling mechanisms, enabling articulation in both horizontal and vertical planes, allowing real-time configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-plane hinge is used for cable tray connection, then the structure is simple and easy to manufacture, but it only enables articulation in one plane (horizontal or vertical), leading to stock and supply issues based on demand
Solution Approach 1:
The hinge is divided into two separate articulated members (first articulated member and second articulated member) that can be independently coupled to cable trays. Each member can articulate independently, allowing the system to achieve multi-plane articulation through the combination of two single-plane articulations, thus resolving the contradiction between versatility and complexity
Solution Approach 2:
The hinge assembly is designed to perform multiple functions: it can articulate cable trays in both horizontal and vertical planes, and can be configured in different arrangements (side-by-side or stacked) depending on installation requirements. This multi-functionality achieves adaptability without proportionally increasing structural complexity
2Adaptability or versatility
If separate horizontal and vertical hinges are manufactured to meet different demands, then each hinge type can be optimized for its specific plane, but it creates stock and supply issues and increases manufacturing variety
Solution Approach 1:
A single hinge assembly design incorporating both horizontal and vertical articulation capabilities eliminates the need to manufacture separate hinge types for different planes. The universal design allows the same product to serve multiple configuration needs, reducing manufacturing variety while maintaining adaptability
Solution Approach 2:
The hinge incorporates dynamic adjustment capabilities through adjustable positioning mechanisms that allow the articulation planes to be configured in different orientations. This dynamic adaptability enables a single static product design to fulfill multiple functional requirements, reducing the need for multiple product variants
3Ease of operation
If a fixed-plane hinge is used, then the manufacturing process is simplified, but it limits the operator's ability to choose between horizontal and vertical configurations in real time
Solution Approach 1:
The hinge assembly incorporates adjustable and reconfigurable features that allow operators to change the articulation plane orientation from horizontal to vertical or vice versa during installation. The adjustable positioning mechanisms enable real-time configuration changes without requiring complex active control systems, balancing operational flexibility with mechanical simplicity
