Rotatable Fishing Lure Skirt Resolves Snagging Contradiction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing lures face challenges in balancing the ability to ensnare fish with the need to navigate through underwater vegetation and structure without getting snagged, while also maintaining visual attractiveness to fish at different depths.
Innovation Solution
The development of a fishing lure with a rotatable member and a shielding skirt that extends outward to deflect vegetation and structure, while being collapsible to expose the hook during a fish strike, and incorporating features such as helical channels and audible vibration generators to attract fish.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the hook is sufficiently exposed to ensnare a fish attacking the lure, then the hooking ability is improved, but the likelihood of ensnaring vegetation or structure during retrieval increases
Solution Approach 1:
The patent employs a flexible guard that dynamically changes its configuration based on operational conditions. During retrieval, the guard extends to protect the hook from vegetation. Upon fish strike, the guard collapses to expose the hook for effective hooking. This dynamic adaptation resolves the contradiction between hook protection and hooking ability.
Solution Approach 2:
The flexible guard's physical state changes from an extended protective configuration during retrieval to a collapsed exposing configuration during fish strike. This parameter change in the guard's spatial arrangement allows the system to switch between protecting the hook and exposing it for hooking, resolving the technical contradiction.
2Object-affected harmful factors
If flexible guards are mounted about the hook tip to deflect weeds and structure, then protection from snagging is improved, but hook penetration into the fish becomes more difficult
Solution Approach 1:
The flexible guard transitions from a rigid-appearing extended state during retrieval to a collapsed state during fish strike. This dynamic collapse removes the barrier between the hook and the fish, enabling effective penetration while maintaining protection during retrieval.
Solution Approach 2:
The guard is pre-positioned in an extended protective configuration before fish strike occurs. This preliminary protection deflects vegetation during retrieval, and the guard's design ensures it will automatically collapse upon strike to enable hook penetration.
3Object-affected harmful factors
If the lure body or forward-extending lip contacts vegetation to be retrieved on surface or shallow trajectory, then passage through vegetation is improved, but exposure to deeper-dwelling fish is limited
Solution Approach 1:
The flexible guard's ability to collapse upon fish strike allows the lure to effectively operate at various depths. When a deeper-dwelling fish strikes, the guard collapses to expose the hook, enabling successful hooking even when the lure was retrieved at a trajectory that contacted vegetation.
Solution Approach 2:
The flexible guard automatically responds to fish strike by collapsing to expose the hook, without requiring manual intervention. This self-service mechanism allows the lure to adapt to strikes from fish at any depth, expanding its versatility beyond surface-only fishing.
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 solution effectively protects the hook from snagging on underwater vegetation while allowing it to be exposed for hooking fish, and enhances the lure's attractiveness through rotation and vibration, improving fishing success in various aquatic environments.

AI summary
A fishing lure includes a body portion, a hook member coupled to a junction region disposed distal of the body portion, and a shielding skirt extending from the body member. The body portion includes a rotatable member configured to rotate about a central longitudinal axis in the presence of fluid friction acting against the lure. The shielding skirt extends outward from the body portion and is configured to assume a first configuration during retrieval of the lure that defines a protective zone that protects the hook member from ensnaring structures, such as submerged vegetation. The shielding skirt is collapsible by contacting lateral forces into a second configuration in which one or more terminal endpoints of the hook member is exposed and available to ensnare the source of the contacting lateral force, such as a fish. The shielding skirt resiliently returns to the first configuration when the lateral forces are removed.
