Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing equipment fails to efficiently pull high voltage cables through long boreholes due to high friction forces, which can cause cable damage and overload, and lacks the ability to manage cables in organized bundles or accommodate multiple cable types.
Innovation Solution
A clamping device with a clamping element that constrains cables and an insertion element with friction-reducing wheels, allowing for even force distribution and reduced friction, capable of bundling multiple cables including high voltage and fiber optic cables, and equipped with adjustable coupling elements for distributed force application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cables are pulled directly through long boreholes without friction reducing means, then the cable bundle can be pulled through the borehole, but high friction forces cause cable damage and overload
Solution Approach 1:
The patent introduces a clamping device with friction reducing means (wheels or rollers) as an intermediary between the cable bundle and the borehole wall. This mediator transfers the pulling forces through multiple contact points while reducing friction, preventing cable damage and overload during pulling through long boreholes
Solution Approach 2:
The patent replaces direct cable-to-borehole contact with a mechanical system consisting of clamping devices equipped with wheels or rollers. This substitution transforms the friction-based direct pulling into a rolling contact system, significantly reducing friction forces and enabling safe pulling through long boreholes
2Ease of operation
If cables are pulled through long boreholes with steep incline, then the cables can be installed, but forces become so great that cables can be overloaded
Solution Approach 1:
The patent divides the cable bundle into multiple sections, each secured by separate clamping devices distributed along the longitudinal direction. This segmentation allows pulling forces to be distributed across multiple clamping points rather than concentrated on a single point, preventing cable overload during installation through long boreholes with steep inclines
Solution Approach 2:
The patent transitions from single-point pulling to multi-point distributed pulling along the longitudinal dimension of the cable bundle. By attaching multiple clamping devices at different positions, the system distributes forces across multiple dimensions, reducing the stress on any single cable section
3Loss of energy
If cables are laid in organized bundles, then power loss is reduced and cable management is improved, but existing equipment lacks the ability to bundle multiple cable types together
Solution Approach 1:
The patent designs a universal clamping device that can accommodate and bundle multiple types of cables (high voltage cables, fiber optic cables, and other cables) together in a single organized bundle. This multi-functional device enables mixed cable bundling while maintaining organized cable management and reducing power loss through proper cable arrangement
