Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional swim baits fail to replicate the natural swimming motions and stability of live baitfish, exhibiting unnatural lateral wobble, rolling, and instability during retrieval and sinking, leading to inconsistent performance.
Innovation Solution
A multi-segmented, soft-bodied swim bait with clear, stiff control planes inserted in each segment to generate lifelike swimming motions, adjustable to accommodate various water conditions and retrieve speeds, while maintaining a natural profile and simulating the stiffness of baitfish spines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If conventional swim baits are designed with segmented bodies and curved tails to generate motion, then the lure produces swimming motion in water, but the motion becomes unnatural with exaggerated lateral wobble and rolling
Solution Approach 1:
The lure body is divided into multiple segments (head, midsection, tail) that can move independently. Control planes are inserted at specific segments to regulate the motion of each section separately, allowing natural swimming motion while preventing exaggerated wobble and rolling.
Solution Approach 2:
The patent adjusts physical parameters such as the stiffness, size, and position of control planes within body segments to fine-tune the lure's swimming characteristics. By changing these parameters, the lure achieves natural motion patterns while maintaining stability across different retrieval speeds.
2Shape
If the swim bait body is made soft and flexible to resemble baitfish, then the lure looks more realistic, but it becomes unstable during faster retrieves and trolls
Solution Approach 1:
The lure combines soft flexible body material with stiff clear control planes inserted within segments. This composite structure maintains the realistic appearance of soft plastic baitfish while the embedded control planes provide structural stability during fast retrieves and trolling conditions.
Solution Approach 2:
Control planes act as intermediary elements between the soft body material and the water environment. These clear stiff planes regulate hydrodynamic forces acting on the soft body, preventing excessive deformation and instability while maintaining natural movement patterns.
3Use of energy by moving object
If extensions such as twist, curl, paddle, or vortex tails are added to generate motion, then the lure produces swimming action, but the motion becomes erratic and unnatural
Solution Approach 1:
Instead of using exaggerated extensions, the patent segments the tail into controlled sections with inserted control planes that regulate movement. This produces subtle natural tail beats rather than erratic motions from oversized extensions.
Solution Approach 2:
The control plane configuration copies the natural hydrodynamic function of real fish fins and bodies. By mimicking how actual baitfish move through water with subtle body undulations, the lure achieves natural swimming action without needing exaggerated artificial extensions.
4Speed
If the swim bait is designed to sink naturally, then it mimics baitfish behavior when retrieve stops, but it tumbles and sinks uncontrollably instead of gliding upright
Solution Approach 1:
The control planes function as hydrodynamic counterweights that create stabilizing forces opposite to the sinking motion. When the lure stops being retrieved, these control planes generate lift and directional control, preventing tumbling and enabling the lure to sink in a controlled, upright orientation similar to natural baitfish.

AI summary
A multi-segmented, soft-bodied, artificial fishing lure or swim bait with a natural profile includes plastic control planes in each body segment to generate a lure that is stable in the water, and demonstrates realistic swimming motions in a range of retrieve speeds and even when allowed to sink. At least one clear, stiff plastic control plane is inserted in each body segment to generate a lifelike swimming motion when the lure is retrieved. Each control plane may be moved within a range of positions to provide realistic motions for specific fishing techniques. The control planes inserted into and sometimes through the lure body are invisible in the water and are adjustable to accommodate a range of water conditions, densities and temperatures. The placement of control planes create the ability to limit unnatural/undesirable movements and expand or accentuate natural and desirable movements in each segment of the body of the lure.
