Sequentially Deploying Shallow Water Anchor for Quiet Fishing

Solution Overview

Problem

Conventional anchors used in shallow water fishing drift due to currents, produce noise and splash, obscure underwater visibility, and can damage aquatic vegetation, making it difficult to maintain a stable and quiet fishing position.

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, featuring a motor-driven cable system and pulley mechanism to minimize noise and visibility impact, and a slip clutch to manage load thresholds.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

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

Engineering Contradiction:

Improveanchoring capabilityVSAvoidnoise and splash

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The anchor system is divided into multiple segments: a housing, a first anchor extension, and a second anchor extension. These segments deploy sequentially rather than as a single unit, allowing controlled deployment that minimizes noise and splash while maintaining anchoring reliability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The first anchor extension deploys preliminarily before the second anchor extension. This preliminary action allows the first extension to make initial contact with the waterbed, establishing a foundation that reduces the impact and noise when the second extension deploys.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If a conventional anchor is thrown into the water, then the boat can be anchored, but the anchor drags across the bottom and stirs up particulate matter obscuring the view

Engineering Contradiction:

Improveanchoring capabilityVSAvoidunderwater visibility

Core Design Contradiction:

ReliabilityVSIllumination intensity

Solution Approach 1:

The anchor system transitions from a static, single-deployment design to a dynamic, multi-stage deployment process. The sequential extension and controlled penetration into the waterbed minimize dragging and particulate disturbance, preserving underwater visibility.

Inventive Principle:

Principle #15Dynamics

3Reliability

If a conventional anchor is used, then the boat can be anchored, but the boat drifts due to currents

Engineering Contradiction:

Improveanchoring capabilityVSAvoidboat position stability

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The controller automatically monitors and adjusts the anchor extensions to ensure proper engagement with the waterbed. This self-service capability ensures the anchor maintains optimal holding power against currents without requiring manual intervention, stabilizing the boat position.

Inventive Principle:

Principle #25Self-service

4Reliability

If a conventional anchor is thrown into the water, then the boat can be anchored, but the mass damages the vegetation growing at the bottom

Engineering Contradiction:

Improveanchoring capabilityVSAvoidvegetation damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

By segmenting the anchor into multiple extensions that deploy sequentially, the system reduces the impact force on the waterbed and vegetation compared to a single heavy mass being thrown in. The distributed deployment minimizes damage to aquatic vegetation.

Inventive Principle:

Principle #1Segmentation

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 anchor system effectively anchors a boat without drifting, reduces noise and water disturbance, and minimizes damage to underwater vegetation, allowing for precise and quiet fishing by ensuring the anchor fully penetrates the waterbed without excessive noise or obscuration.

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.
