Angling Rig With Braided Sheath and Metal Core
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing rig technologies, such as rig tubing and leader materials, fail to effectively maintain a stable and camouflaged position on the lake bed without spooking fish, as they lack a braided sheath that can conform to irregular surfaces and provide adequate weight and camouflage.
Innovation Solution
A coaxial sheath of braided synthetic polymer filaments surrounds a concatenated metal member, which can be a chain or close-wound helix, providing weight, flexibility, and camouflage, replacing conventional leadcore and allowing the fishing line to be easily threaded through.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a close-wound helix of metal wire is used for rig tubing, then the tubing follows the contours of the water bed and provides stability, but the weight per unit length is relatively high and visibility to fish increases
Solution Approach 1:
The patent combines metal wire helix with braided synthetic polymer sheath to create a composite structure. The metal wire provides stability and contour-following properties, while the synthetic polymer sheath reduces overall weight and improves camouflage by blending with the underwater environment.
Solution Approach 2:
The braided sheath acts as a flexible outer layer that conforms to the helix structure while providing a more natural appearance and reduced weight compared to solid metal tubing.
2Stability of the object's composition
If a close-wound helix of metal wire is used for rig tubing, then the tubing follows the contours of the water bed, but visibility to fish increases due to metal reflection
Solution Approach 1:
The braided sheath serves as a flexible outer shell that conceals the reflective metal wire helix, preventing fish from detecting the rig through visual reflection while maintaining the helix's contour-following stability.
Solution Approach 2:
The braided sheath can be colored to match the underwater environment, changing the visual appearance of the rig from reflective metal to camouflaged material that blends with the lake bed.
3Stability of the object's composition
If leadcore material is used to stabilize the fishing line, then weight is provided for stability, but the line cannot be easily threaded and flexibility is reduced
Solution Approach 1:
The braided sheath creates a flexible, tubular structure that allows the fishing line to be easily threaded through while maintaining the weight and stability properties of the metal wire core.
Solution Approach 2:
The rig is segmented into distinct functional components: the metal wire helix for weight and stability, and the braided sheath for flexibility and ease of line threading, combining advantages of both materials.

AI summary
The angling rig comprises a core and, surrounding the core, a coaxial sheath of braided synthetic polymer filamentary material, wherein the core comprises a negatively buoyant, elongate, flexible concatenated member of metal wire (36). The core may comprise a close-wound helix of metal wire (36) through which a fishing line (10) may be fed, and surrounding the helix, a coaxial sheath of braided synthetic polymer filamentary material (38), in which case the rig forms rig tubing (24). Alternatively, the core may be of a metal chain (36), in which case the rig generally forms an angling leader material (24).
