Shallow Water Anchor with Sequential Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional anchors used in shallow water fishing drift due to currents, create noise and splash, obscure the water, and can damage vegetation, making it difficult to maintain a stable position and avoid scaring fish.
Innovation Solution
A sequentially deploying shallow water anchor system with a base member and two anchor extensions, where the first anchor extension extends fully before the second extends, and both deploy in unison, using a motor and pulley system to minimize noise and exposure, and includes a control interface to ensure proper deployment and retraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional anchor is used to anchor a boat in shallow water, then the boat can be anchored, but the boat drifts due to currents
Solution Approach 1:
The patent employs a dynamically adjustable anchor system where the anchor arm can change its angle and extension length in real-time to adapt to varying current conditions. The actuation mechanism allows the anchor to optimize its holding position dynamically, ensuring the boat remains stable despite changing water currents.
Solution Approach 2:
The anchor system is divided into multiple segments including a base section, an anchor arm with multiple extendable sections, and independent control mechanisms for each segment. This segmentation allows each part to function independently and contribute to overall anchoring stability, with the ability to adjust each segment's position to counteract current forces.
2Reliability
If a conventional anchor is thrown into the water, then the boat can be anchored, but loud noise and splash are produced that scare away fish
Solution Approach 1:
The patent replaces the traditional mechanical throwing action with an automated actuation system. The anchor is deployed through controlled mechanical actuation from a retracted position, eliminating the need to throw the anchor by hand. This substitution reduces noise and water disturbance by using a controlled, gradual deployment mechanism rather than a sudden throwing motion.
Solution Approach 2:
The anchor system incorporates self-contained actuation mechanisms that automatically deploy and retrieve the anchor without requiring manual intervention. The system uses integrated motors and control systems to manage the anchoring process, reducing human interaction and associated noise while maintaining reliable anchoring function.
3Reliability
If a conventional anchor is used, then the boat can be anchored, but the anchor drags across the bottom and stirs up particulate matter that obscures the fisherman's view
Solution Approach 1:
The anchor system dynamically adjusts the anchor arm's extension length and angle based on bottom conditions and current strength. This dynamic adjustment allows the anchor to establish firm contact with the bottom without excessive dragging, minimizing disturbance to particulate matter and maintaining water clarity for the fisherman's view.
Solution Approach 2:
The system changes operational parameters such as anchor extension length, arm angle, and deployment speed to optimize performance. By adjusting these parameters, the anchor can penetrate the bottom effectively without dragging, thereby preventing excessive stirring of sediment and preserving water transparency.
4Reliability
If a conventional anchor is used, then the boat can be anchored, but the anchor mass damages the vegetation growing at the bottom of the body of water
Solution Approach 1:
The anchor system uses a segmented anchor arm structure with multiple extendable sections rather than a single large mass. This segmentation distributes the anchoring force across multiple smaller contact points, reducing the concentration of force on any single point of vegetation and minimizing damage to the underwater ecosystem.
Solution Approach 2:
The system adjusts operational parameters including anchor extension length, deployment angle, and contact force to optimize anchoring effectiveness while minimizing environmental impact. By controlling these parameters, the anchor can secure the boat reliably while reducing damage to bottom vegetation through controlled, minimal-contact anchoring.

AI summary
A shallow water anchor is provided. The shallow water anchor comprises a first anchor extension and a second anchor extension axially received by a housing. The first anchor extension is axially received by the second anchor extension such that the first and second anchor extensions are sequentially deployable from the housing using an actuation arrangement. The actuation arrangement is controlled by a control interface that is operable to detect when the shallow water anchor has reached a fully extended state and fully retracted state. The shallow water anchor further includes a biasing compensator that compensates for fluctuations in the overall depth of water the anchor is deployed in due to waves or other anomalies.
