Spring-Actuated Weedless Fishing Lure With Hook Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weedless fishing lures often interfere with hook embedding in a fish's mouth, leading to missed catches and increased risk of the fish swallowing the lure, making it difficult to release the fish without harm.
Innovation Solution
A spring actuated weedless lure design that moves the hook in a longitudinal direction, extending it 1-3 inches from the lure body upon fish strike, using a guard to retract the hook initially and a spring to extend it securely into the fish's mouth, minimizing interference and reducing lure swallowing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a guard mechanism is used to prevent the hook from snagging on plant material, then the weedless function is improved, but the hook embedding effectiveness deteriorates
Solution Approach 1:
The hook is designed to be dynamic rather than static, transitioning from a retracted position (protected by guard and housing) to an extended position (projecting from housing). This dynamic movement allows the hook to be both protected during retrieval and effective during fish engagement, resolving the contradiction between weedless function and hook embedding effectiveness
Solution Approach 2:
The hook system is segmented into distinct functional zones: the retracted position where the guard and housing protect the hook from plants, and the extended position where the hook projects freely for effective embedding. This segmentation allows each zone to optimize its specific function without interfering with the other
2Object-affected harmful factors
If the hook is retracted within the lure body for weedless operation, then plant entanglement is prevented, but the fish strike effectiveness deteriorates
Solution Approach 1:
The spring mechanism performs preliminary action by pre-loading energy during the retracted phase, ready to rapidly extend the hook upon fish strike. This preliminary preparation ensures that when the fish engages the lure, the hook is immediately available in an extended position for effective embedding, maintaining both weedless operation and catch effectiveness
3Object-affected harmful factors
If the guard mechanism is used to protect the hook, then weedless function is improved, but the fish mouth engagement area deteriorates
Solution Approach 1:
The solution transitions from a two-dimensional planar guard structure to a three-dimensional extended hook configuration. When extended, the hook projects outward from the housing, creating additional spatial dimension for fish mouth engagement that is independent of the guard's protective function, thereby increasing the effective engagement area without compromising weedless operation
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
Enhances fish catch success by ensuring the hook embeds effectively in the mouth and allows easier release of the fish without causing harm, while protecting against plant entanglement.
Implementation Method 1
a spring disposed within the housing and configured to move a hook in a substantially longitudinal direction

AI summary
A spring actuated weedless fishing lure increases the chances of successfully catching a fish without entangling a hook on plant material. A weedless guard system prevents the hook from catching on weeds and compresses a spring to hold the spring and hook in a retracted position. When a fish strikes, the weedless guard system is released allowing the spring to expand and push the hook in a longitudinal direction to an expanded position away from other parts of the lure. This expanded position provides a greater area for the fish's mouth to engage with the hook without interference from other parts of the lure. The expanded position also allows the hooks to embed closer to the front of a fish's mouth and reduces the risk of the fish swallowing the whole lure.
