Sidetracker Wing Rotation for Lateral Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing lures for deep-sea fishing, such as those used for catching large fish like marlin, tuna, and sharks, often struggle to effectively navigate through turbulent water caused by a boat's motor, leading to reduced effectiveness in attracting and catching these species.
Innovation Solution
A fishing sidetracker with a torpedo-shaped body, fins, and a detachable wing that rotates within an X-shaped channel to control vertical and lateral movement, allowing it to maintain position and direction while being pulled behind a boat, thereby keeping lures out of turbulence and optimizing their presentation to fish.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fishing lures are positioned directly behind the boat, then they are easy to deploy and retrieve, but they experience high turbulence from the boat's motor which reduces their effectiveness
Solution Approach 1:
The sidetracker serves as an intermediary device between the boat and the fishing lures. It is deployed behind the boat and uses its hydrodynamic properties (fins and wing) to position itself in the turbulent wake, then holds the lures at a lateral offset from this turbulence zone, effectively mediating the connection between the boat and lures while protecting them from harmful turbulence.
Solution Approach 2:
Instead of positioning lures only in the vertical dimension behind the boat, the sidetracker introduces a lateral dimension by using its wing to shift the lure position sideways. This dimensional change moves the lures out of the direct turbulent path while maintaining their deployment behind the boat, resolving the contradiction between ease of deployment and turbulence avoidance.
2Adaptability or versatility
If the sidetracker uses a fixed wing configuration, then the structure is simple and reliable, but it cannot adapt to different fishing conditions and water states
Solution Approach 1:
The wing is made dynamic rather than fixed. It can rotate about an axis within the channel, allowing it to adjust its angle relative to the direction of travel. This dynamic capability enables the sidetracker to adapt to varying water conditions, currents, and fishing scenarios while maintaining a relatively simple overall structure that relies on passive hydrodynamic forces for operation.
Solution Approach 2:
The sidetracker is segmented into distinct functional components: the body, the channel containing the wing, the fins for vertical control, and the detachable wing for lateral control. This segmentation allows each component to be optimized independently and facilitates the selective adjustment of the wing while keeping the rest of the structure simple and robust.
3Adaptability or versatility
If the wing is permanently attached to the body, then the structure is more rigid and stable, but it cannot be adjusted or removed for different fishing scenarios
Solution Approach 1:
The attachment system transitions from static (permanent) to dynamic (adjustable). The wing can be rotated within the channel and detached when needed, providing adaptability while maintaining stability during active use through the stabilizing effect of the channel constraints and hydrodynamic forces.
Solution Approach 2:
The detachable wing represents a segmented design where the lateral control component can be separated from the main body. This segmentation enables the wing to be removed or reconfigured for different fishing scenarios while the main body structure remains stable and intact, resolving the contradiction between adjustability and structural stability.
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 sidetracker effectively positions fishing lures to the left or right of the boat, reducing turbulence interference and enhancing the visibility and movement mimicry of the lures, increasing the chances of attracting large game fish like marlin, tuna, and sharks.
Implementation Method 1
The first and second fins are configured to control a vertical position of the body in water through which the body is moving
Implementation Method 2
The wing is configured to control a lateral position of the body in water through which the body is moving
