Resilient Fishing Lure with Hinged Jaw Flaps and Serpentine Tail
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing lures are large, complex, and expensive, failing to effectively simulate the movements of live bait in a compact and cost-effective manner.
Innovation Solution
A resilient fishing lure with a unitary body shaped like a worm or amphibian larvae, featuring a longitudinal aperture, hinged jaw flaps for water resistance, and an 'S' or square-wave routing of the fishing line through apertures to transform from an elongate to a serpentine configuration when pulled, made from injection-molded elastomeric materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fishing lures use multiple assembled components to simulate live bait movement, then the movement simulation capability is improved, but the device complexity and manufacturing cost increase significantly
Solution Approach 1:
The patent combines multiple separate components (body, spring mechanism, fins, hooks) into a single integrated elastomeric body with embedded features. The body is injection-molded as one piece with recesses, protrusions, and attachment points that perform multiple functions, eliminating the need for separate parts and assembly steps while maintaining the live-bait simulation capability.
Solution Approach 2:
The elastomeric body serves multiple functions simultaneously: it provides the main structure, contains the spring mechanism for movement simulation, supports the fins for water resistance, and includes attachment points for hooks and line. This multi-functional design reduces overall device complexity while achieving reliable live bait movement simulation.
2Reliability
If traditional fishing lures use multiple assembled components to simulate live bait movement, then the movement simulation capability is improved, but the manufacturing cost increases
Solution Approach 1:

The body is injection-molded as one piece with recesses, protrusions, and attachment points that perform multiple functions, eliminating the need for separate parts and assembly steps while maintaining the live-bait simulation capability.
Solution Approach 2:
The patent changes the material parameter from traditional rigid plastics or metals to elastomeric materials that can be injection-molded in a single operation. This material parameter change enables the body to be formed with embedded spring mechanisms and flexible fins in one manufacturing step, dramatically reducing assembly operations and cost.
3Strength
If the fishing line passes through small apertures in the resilient body, then the structural integrity is improved, but the sliding friction increases
Solution Approach 1:
The patent changes the aperture diameter parameter from small (which would maintain structural integrity) to large (which reduces friction). The elastomeric material and injection-molding process allow the body to maintain strength while accommodating larger apertures for the fishing line, reducing sliding friction during retrieval.
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 lure provides a realistic simulation of live bait movement at a significantly lower cost, being simpler and more affordable to manufacture, while maintaining effectiveness in water resistance and movement transformation.
Implementation Method 1
a resilient body molded to appear like a cross between a worm and an amphibian larvae... The body is unitary, having a head equipped with a longitudinal aperture that curves or otherwise transitions to an exterior surface of the body
Implementation Method 2
An anterior portion of the head is equipped with a water brake that automatically deploys as the lure is pulled forward through water with the fishing line. The water brake includes a pair of resiliently-hinged upper and lower jaw flaps, which are partially open, and which open further in opposite directions to positions of maximum drag when the lure is pulled forward through the water

AI summary
A resilient fishing lure, which simulates the movement of live bait when a fisherman tugs on the fishing line, includes a molded, resilient worm/amphibian larvae-like body. The body is unitary, having a head equipped with a longitudinal aperture, an attached tail equipped with at least two apertures, and at least one hook secured to the body. A fishing line is routed, first through the longitudinal aperture in the head, then in an “S” pattern through the remaining apertures, and secured to the body through the aperture farthest from the head. Resiliently-hinged jaw flaps on an anterior portion of the head open to positions of maximum hydrodynamic drag when the lure is pulled forward through the water, thereby transferring a portion of the pulling force to the tail so that is transformed from an elongate configuration to a serpentine configuration.
