Sequential Shallow Water Anchor Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional anchors used in shallow water fishing drift due to currents, produce noise and splash, obscure water clarity, and can damage underwater vegetation, making it difficult to maintain a stable fishing position without scaring away 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 secured, but the anchor produces noise and splash that scare away fish
Solution Approach 1:
The anchor system is divided into multiple segments: a first anchor extension and a second anchor extension that deploy sequentially. This segmentation allows the anchor to set gently on the bottom without the loud splash of a single heavy anchor, reducing noise and disturbance to fish while maintaining reliable anchoring capability.
Solution Approach 2:
The first anchor extension deploys and sets into the bottom beforehand before the second anchor extension is deployed. This preliminary action allows the anchor to be partially secured in a quiet manner first, then completed without scaring away fish that might be attracted to the initial deployment noise.
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 water
Solution Approach 1:
By dividing the anchor into two extensions that deploy sequentially, the system reduces the dragging effect on the bottom. The first extension sets gently first, and the second extension follows without needing to drag across the bottom with full force, thereby minimizing disturbance to particulate matter and preserving water clarity for sight fishing.
3Reliability
If a conventional anchor is used, then the boat can be anchored, but the anchor can damage the vegetation growing at the bottom of the water
Solution Approach 1:
The segmented anchor system with two extensions that deploy sequentially reduces the impact force on bottom vegetation. The first extension sets gently without dragging, and the second extension deploys after the first is secured, minimizing the risk of damaging aquatic vegetation compared to a single conventional anchor that must be thrown with force.
Solution Approach 2:
The first anchor extension deploys and sets into the bottom in advance before the second extension is released. This preliminary deployment allows the anchor to secure the boat without the second extension needing to drag across the bottom with full anchoring force, thereby protecting vegetation from damage.
4Reliability
If a conventional anchor is thrown into the water, then the boat can be anchored, but the boat drifts due to currents when anchored
Solution Approach 1:
The two-stage anchor deployment system ensures proper setting sequence that maximizes anchoring effectiveness. The first extension sets initially, followed by the second extension that secures the boat more firmly against current forces, providing better positional stability than a single conventional anchor that may not set optimally.
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 prevents damage to underwater vegetation, allowing for precise and quiet fishing.
Implementation Method 1
A sequentially deploying shallow water anchor with a base member and two anchor extensions, where the first anchor extension extends fully before the second extends
Implementation Method 2
The actuation arrangement is operable to sequentially axially drive the first and second anchor extensions in a deployment direction

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.
