Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for reducing the coefficient of friction in wires and cables during installation either compromise the chemical, physical, or electrical properties of the materials or are time-consuming and labor-intensive.
Innovation Solution
A composition of aqueous emulsion, compatible with various insulating materials, is applied to the wire or cable after cooling, using a spraying device or submerging in a bath, to reduce friction and pulling force without affecting the material properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If lubricating agents are incorporated into the insulating material during manufacturing at high temperature, then the coefficient of friction is reduced, but the chemical, physical, and electrical properties of the wire or cable are adversely affected
Solution Approach 1:
The lubricating composition is applied to the wire or cable surface before installation, rather than being incorporated during manufacturing. This preliminary application allows the lubricant to be in place when needed without exposing the insulating material to high temperatures that would degrade its properties
Solution Approach 2:
A water-based lubricating composition containing lubricating agents serves as an intermediary substance applied to the surface of the wire or cable. This intermediary provides the necessary lubrication without requiring direct incorporation into the insulating material, thus avoiding thermal degradation
2Object-affected harmful factors
If hand application of lubricating agents is used at the job site, then the coefficient of friction is reduced, but the installation process becomes time consuming and labor intensive
Solution Approach 1:
The lubricating composition is applied to the wire or cable surface before installation, rather than being incorporated during manufacturing. This preliminary application allows the lubricant to be in place when needed without exposing the insulating material to high temperatures that would degrade its properties
Solution Approach 2:
The lubricating composition is applied using a spray device or by submerging the wire or cable in a bath, providing efficient and uniform application. This method is faster and less labor-intensive than hand application while ensuring complete coverage
3Object-affected harmful factors
If traditional lubrication methods are used, then friction is reduced, but additional materials and equipment must be present at the job site
Solution Approach 1:
The lubricating composition is integrated into the wire or cable manufacturing process itself, making the wire or cable self-lubricating. This eliminates the need for separate lubrication equipment and materials at the job site, as the lubrication function is built into the product
Solution Approach 2:
The wire or cable is provided with lubricating properties through the applied composition, allowing it to lubricate itself during installation without requiring external lubrication systems or additional materials at the installation site
