Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support structures for wires fail to provide effective radial compression and tension maintenance without damaging the wire's outer sheath, and they lack efficient methods to securely engage and stabilize the wire.
Innovation Solution
A support device with multiple helically wound leg portions and varying surface roughness to securely engage and compress the wire, utilizing a combination of first, third, and fourth helical windings to provide axial alignment and frictional engagement, ensuring the wire is non-movable once wound around the support device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a support structure applies radial compression to maintain wire tension, then the wire tension is maintained, but the wire's outer sheath may be damaged
Solution Approach 1:
The support structure incorporates multiple leg portions with different surface roughness characteristics at different locations. Specifically, the first leg portion has a first surface roughness, the second leg portion has a second surface roughness, and the third leg portion has a third surface roughness. This local variation in surface quality allows different regions to perform different functions: smoother regions minimize damage to the wire sheath while rougher regions provide adequate friction for tension maintenance.
2Device complexity
If a support structure uses simple linear geometry, then the device complexity is reduced, but the ability to securely engage and stabilize the wire is compromised
Solution Approach 1:
The support structure employs helical windings instead of simple linear geometry. The first leg portion includes a first helical winding, the second leg portion includes a second helical winding, and the third leg portion includes a third helical winding. These helical configurations provide natural wire engagement through the spiral geometry, improving wire stabilization while maintaining relatively simple device construction.
3Ease of manufacture
If all leg portions have the same surface roughness, then the manufacturing process is simplified, but the wire engagement and friction control is insufficient
Solution Approach 1:
The support structure incorporates multiple leg portions with different surface roughness characteristics at different locations. Specifically, the first leg portion has a first surface roughness, the second leg portion has a second surface roughness, and the third leg portion has a third surface roughness. This local variation in surface quality allows different regions to perform different functions: smoother regions minimize damage to the wire sheath while rougher regions provide adequate friction for tension maintenance.
4Reliability
If the support device uses multiple helical windings with different characteristics, then the wire engagement and compression are improved, but the device complexity increases
Solution Approach 1:
The support structure is divided into multiple distinct leg portions, each with its own helical winding characteristics. The first leg portion has a first helical winding with a first surface roughness, the second leg portion has a second helical winding with a second surface roughness, and the third leg portion has a third helical winding with a third surface roughness. This segmentation allows each portion to be optimized for specific functions while maintaining overall structural coherence.
Solution Approach 2:
Multiple leg portions with different helical winding characteristics perform multiple functions simultaneously: the first leg portion engages the wire with its specific surface roughness, the second leg portion provides additional engagement with different friction characteristics, and the third leg portion completes the compression and stabilization. This multi-functionality achieves reliable wire engagement and compression through coordinated action of multiple components.
