Flexible Cable With Alloy Wire Conductor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flexible cables used in industrial settings are too rigid due to emphasis on durability, compromising flexibility.
Innovation Solution
A flexible cable design incorporating a conductor formed by twisting annealed copper wires and alloy wires, with a mixing proportion of copper alloy wires between 10 to 70%, providing a durable and flexible solution with enhanced conductivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional flexible cable with annealed copper wires is used, then flexibility is improved, but durability against breaking deteriorates
Solution Approach 1:
The patent applies composite materials by combining annealed copper wires (providing flexibility) with alloy wires such as stainless steel or copper alloy wires (providing durability and breaking resistance). This composite conductor structure allows the cable to simultaneously achieve both flexibility and durability against breaking, resolving the technical contradiction between these two properties.
2Ease of operation
If the mixing proportion of alloy wire is less than 10%, then flexibility is maintained, but durability deteriorates
Solution Approach 1:
The patent applies parameter changes by optimizing the mixing proportion of alloy wires in the conductor to be 10% or more. This specific parameter threshold ensures that the cable achieves sufficient durability while maintaining acceptable flexibility. By changing this critical parameter (alloy wire proportion), the patent resolves the contradiction between flexibility and durability.
