Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable holding devices for bundles in cable tracks are complex to produce, require multiple support types for varying diameters, and offer inadequate electromagnetic and electrical protection, leading to assembly complications and potential defects.
Innovation Solution
A device with a support having parallel faces and retractable fasteners, featuring a central guide bore and a movable thruster with a non-return blocking system, allows for individual and rapid assembly and secure clamping of cables without tools, using a single type of device for various diameters, and provides continuous ducts for enhanced protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vertical slots and lugs are formed in duct flanks to enable clasp-based holding, then cable bundles can be secured in the duct, but the duct production becomes complicated and adjacent ducts sharing common walls are affected by space constraints
Solution Approach 1:
The invention extracts the holding mechanism from the duct structure itself by introducing a separate, movable holding device that can be independently positioned and secured within the duct. This separates the functions of duct protection and cable securing, allowing the duct to maintain its simple continuous structure while the holding device provides the necessary retention capability.
Solution Approach 2:
The holding device incorporates a movable thruster mechanism that can dynamically adjust its position along the duct length and apply variable clamping force to the cable bundle. This dynamic capability replaces the static, fixed-position clasps of prior art, enabling flexible adaptation to different cable positions and diameters without modifying the duct structure.
2Reliability
If bores are formed in duct bottoms for fasteners, then cable bundles can be secured, but duct production becomes complicated and electromagnetic protection is compromised
Solution Approach 1:
The invention removes the need for bores or openings in the duct structure by extracting the securing function to a separate holding device that operates from within the duct. This maintains the duct's continuous, sealed structure, preserving electromagnetic shielding while achieving reliable cable retention through internal clamping mechanisms.
3Adaptability or versatility
If multiple support types with different dimensions are provided for various cable diameters, then different cable sizes can be accommodated, but assembly complexity increases and costs rise
Solution Approach 1:
The holding device is designed as a universal, multi-functional unit that can accommodate cable bundles of various diameters through a single standardized design. The movable thruster mechanism provides adjustable clamping force and position, eliminating the need for multiple specialized support types while maintaining adaptability to different cable sizes.
Solution Approach 2:
The thruster mechanism provides dynamic adjustment capability, allowing the holding device to adapt to different cable diameters through movement and force variation rather than requiring multiple fixed-dimensional components. This single dynamic device replaces multiple static support types.
4Ease of operation
If resilient supports are used to hold cable bundles, then assembly is simplified, but irregular clamping occurs for various cable diameters leading to potential defects
Solution Approach 1:
The movable thruster mechanism incorporates a feedback-based control system that monitors the clamping force applied to the cable bundle and automatically adjusts to maintain optimal, uniform pressure regardless of cable diameter. This feedback control eliminates the irregular clamping that occurs with simple resilient supports.
