Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable glands require laborious and tool-dependent checks for correct fitting and can loosen over time, leading to unintended separation of cables from connectors or bushings.
Innovation Solution
A clamping ring system comprising two coaxially oriented rings connected by deformable ribs, which deforms to fix and seal cables during nut screwing, ensuring automatic fixing and sealing without additional steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cable glands are screwed onto the plug connector or cable bushing to achieve a defined torque, then the cable is fixed securely, but the fitting check becomes laborious and requires special tools, and the cable gland may loosen after storage period
Solution Approach 1:
The clamping ring performs self-checking through its own deformation state. The ribs deform automatically during assembly to engage with the cable, and the degree of deformation visually indicates correct installation without requiring external tools or complex inspection procedures. The system serves itself by using the deformation as both the fixing mechanism and the verification indicator.
Solution Approach 2:
The invention replaces the torque-based mechanical fastening system with a deformation-based system. Instead of relying on torque control and special tools for verification, the system uses the elastic deformation of the ribs to both secure the cable and provide visual confirmation of proper installation, substituting complex mechanical inspection with simple visual assessment.
2Reliability
If conventional cable glands are screwed tightly to prevent loosening, then cable separation is prevented, but the fitting process becomes complex and requires precise torque control
Solution Approach 1:
The invention changes the fixation parameter from torque control to deformation control. The ribs are designed to deform within a specific range during assembly, and this deformation parameter automatically indicates correct installation. By changing from torque (which requires precise control and verification) to deformation (which is self-evident and self-limiting), the fitting process complexity is reduced while maintaining reliable cable fixation.
3Ease of operation
If the clamping ring uses deformable ribs to fix the cable automatically during nut screwing, then the fitting process is simplified and automated, but the structural complexity of the clamping ring increases
Solution Approach 1:
The clamping ring is segmented into multiple deformable ribs that are distributed around the circumference. Each rib independently deforms to engage with the cable, providing distributed fixation. This segmentation allows the complex fixation function to be achieved through multiple simple, identical elements rather than a single complex mechanism, making the overall structure more manageable and manufacturable.
Solution Approach 2:
The clamping ring incorporates dynamic deformable ribs that change shape during the assembly process. The ribs transition from a less deformed state during insertion to a more deformed state during tightening, automatically adapting to the cable and providing progressive fixation. This dynamic behavior enables automated fitting without complex control systems, as the structure itself performs the adjustment.
