Rotating Weedless Fish Lure Hook With Opening Dual Hooks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spinner-type fish lures, such as safety pin lures, face issues where fish strike at the overhead arm instead of the hook, and they are not effective in preventing snagging on weeds, especially in heavily weeded environments.
Innovation Solution
A fish lure component with a hook portion having first and second hook members in an opposing arrangement, a biasing member to maintain a closed configuration, and a vane structure that rotates to transfer motion to the hook portion, allowing it to open during a fish strike.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single hook with overhead arm is used, then the hook is protected from snagging on submerged obstacles, but fish may strike at the blades instead of the hook and the lure is not effective in preventing snagging on weeds
Solution Approach 1:
The single hook is segmented into two opposing hook members that can independently pivot and set. This segmentation allows each hook member to be positioned optimally for hooking fish while the other provides protection, resolving the contradiction between hook effectiveness and snagging prevention.
Solution Approach 2:
The hook members are made dynamic through pivoting motion enabled by the biasing member. The hooks can pivot between a protected position (reducing snagging) and an active setting position (increasing hook effectiveness), allowing the system to adapt to different operational conditions.
2Object-affected harmful factors
If the hook remains in a closed protected position, then snagging on weeds is prevented, but the hook cannot set effectively when a fish strikes
Solution Approach 1:
The biasing member pre-loads the hook members into a closed protected position before fish strike. This preliminary positioning minimizes snagging during retrieval, and the stored energy in the biasing member is ready to rapidly open the hooks when a fish strikes, ensuring both protection and effectiveness.
Solution Approach 2:
The system transitions from a static closed position to a dynamic open position through pivoting motion. The biasing member provides the mechanical energy for this transition, allowing the hooks to rapidly change from a protected configuration to an active hooking configuration in response to fish strike.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design ensures the hook is protected from snagging on submerged obstacles and weeds, while enabling effective hook setting during a fish strike, enhancing the lure's effectiveness in weeded areas.
Implementation Method 1
a biasing member for normally biasing the hook portion in a closed configuration
Implementation Method 2
a vane structure configured to rotate about an axis thereof during movement of the vane structure through a body of water

AI summary
A fish lure component includes a hook portion having first and second hook members disposed in an opposing arrangement. A biasing member for normally biasing the hook portion in a closed configuration is disposed between the first and second hook members. A vane structure is provided to cause the fish lure component to rotate about an axis thereof during movement through a body of water and along a direction that is generally aligned with the axis. The hook portion is operable between the closed configuration and an open configuration in response to a fish strike on the hook portion.
