Angled Keel Lure for Wide Trolling Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fishing lures tend to follow a straight path behind a fishing vessel, missing the undisturbed 'clean water' where predator fish typically feed, limiting exposure to fish and requiring expensive outriggers for wider coverage.
Innovation Solution
A single line of interconnected bait lures with angled keels and lateral wings that guide them laterally outward during trolling, providing stability and planing lift to maintain position on or below the water surface, increasing lateral separation and visibility to fish.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional fishing lures are used, then they follow a straight path behind the vessel, but they miss the clean water where predator fish feed and have limited exposure to fish
Solution Approach 1:
The lure is divided into functional segments: a body portion and a separate keel assembly that can be rotated or adjusted. This segmentation allows the keel to independently control lateral movement while the body maintains forward propulsion, enabling the lure to follow a curved path through clean water while staying connected to the vessel.
Solution Approach 2:
The keel assembly is designed to be rotatable or adjustable relative to the lure body, allowing dynamic modification of the lure's swimming angle and lateral deviation. This dynamic adjustment enables fishermen to optimize the lure's path based on water conditions and target species, maximizing exposure to fish in clean water zones.
2Length of moving object
If outriggers are used to achieve wide lateral separation, then lures can run wide in clean water, but the device complexity and cost increase significantly
Solution Approach 1:
The patent extracts the lateral separation function from the complex outrigger system and integrates it directly into the lure itself through the keel assembly. By removing the need for external outriggers and incorporating the angle-control mechanism within the lure, the design achieves wide lateral separation while dramatically reducing device complexity and cost.
Solution Approach 2:
The lure's keel assembly automatically generates lateral movement and maintains angular orientation through its own hydrodynamic design and rotatable mechanism, without requiring external outrigger support. The lure serves its own lateral separation function, eliminating the need for additional complex support structures.
3Productivity
If lures run wide laterally, then they expose more fish and increase strike opportunities, but stability and planing lift may be compromised
Solution Approach 1:
The keel assembly is pre-configured with specific angular orientations and hydrodynamic profiles that are optimized to provide both lateral deviation and stability. By establishing the correct keel angle before trolling begins, the lure is pre-positioned to simultaneously achieve wide lateral separation and maintain stable planing lift, preventing the stability-productivity trade-off.
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 allows the lures to run wide behind the vessel, enhancing exposure to fish, reducing the need for outriggers, and increasing the chances of catching fish by maintaining stability and planing lift, even in rough waters.
Implementation Method 1
the keel extends from a ventral surface of the body at an angle relative to a longitudinal axis of the body, such that, when trolling in a body of water at or near a surface of the body of water, the body is guided laterally outwardly from a direction of travel
Implementation Method 2
The keel and the lateral wing work in conjunction to provide stability and planing lift for the bait lure when the bait lure is caused to troll in a body of water such that the bait lure maintains a position on or below a surface of the water in a stabile manner

AI summary
Embodiments relate to a single line of a plurality of interconnected bait lures. At least one bait lure can have an elongated body, an angled keel, and a lateral wing. These elements work together to ensure that the single line of a plurality of interconnected bait lures run wide from behind a fishing vessel to expose the lures to favorable water conditions and thereby eliminating the need for expensive outrigger devices.
