Soft Bait Connector with Coil and Pin for Fishing Hook
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing hook designs with soft baits often fail to securely maintain their position, leading to snagging and loss when encountering underwater weeds or branches, due to inadequate retention mechanisms.
Innovation Solution
A fishing hook with a coil of metal wire forming an open space core and a metal pin extending through its axis, providing improved retention and alignment of soft baits, reducing the likelihood of snagging and enhancing security with a single, continuous piece of metal wire.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a simple hook design is used, then device complexity is low, but soft bait retention is poor
Solution Approach 1:
The hook system is divided into distinct functional segments: the original fishing hook for catching fish, and the separate coil connector with pin for securing the soft bait. This segmentation allows each component to specialize in its function - the hook for fishing and the coil-pin assembly for retention - resolving the contradiction by improving reliability through functional division without unnecessarily complicating the overall device.
Solution Approach 2:
The coil connector is inserted through the hook's eye, and the pin extends through the coil's open space core, creating a nested structure where the coil is nested within the hook's eye and the pin is nested within the coil. This nesting arrangement improves soft bait retention by creating multiple retention points while maintaining a compact design that doesn't significantly increase device complexity.
2Loss of energy
If drag reduction is achieved through better alignment, then soft bait performance improves, but retention mechanism complexity increases
Solution Approach 1:
The coil connector and pin are pre-assembled in a specific configuration before attachment to the hook. The coil is formed with a predetermined open space core, and the pin is positioned to extend through this core. This preliminary preparation ensures that when assembled on the hook, the soft bait achieves proper alignment and minimal drag without requiring complex adjustment mechanisms during fishing.
Solution Approach 2:
The coil connector uses a curved, spiral configuration rather than a straight rigid structure. This curvature allows the coil to flex and conform to the hook's eye while maintaining the pin's alignment function. The curved design reduces drag by allowing smoother water flow around the connector and improves retention through the coil's elastic properties, all without significantly increasing device complexity.
3Ease of manufacture
If a single continuous piece of metal wire is used, then manufacturing simplicity improves, but retention effectiveness may be compromised
Solution Approach 1:
The coil connector and pin are formed from a single continuous piece of metal wire, merging two potential components into one. This simplifies manufacturing by requiring only one forming operation and eliminates the need for separate assembly steps to join the coil and pin. Despite being a single piece, the design maintains retention effectiveness through the coil's elastic properties and the pin's penetration through the soft bait, demonstrating that merging components can both simplify manufacture and maintain reliability.

AI summary
The present invention is a fishing hook rig where a connector is formed with a spiral wire surrounding a portion of a straight wire pin and the connector is fixed at one end to a top end of a fishing hook. A soft bait is first fixed to the connector and then to a barbed end of the hook to provide a secure, snag resistant rig for fishing.
