Decoy Anchor Deployment System with Collapsible Keels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional decoys face challenges with anchor deployment flexibility across varying water depths and efficient storage, as well as issues with anchor line entanglement and keel positioning during transport.
Innovation Solution
The decoy features a collapsible anchor deployment system with a crank, spool, and locking mechanism that allows for rapid anchor deployment and retraction, along with collapsible keels that can be extended or stored within the decoy, and a movable head that can be locked in multiple positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a standard anchor line is used, then the decoy can be anchored in some depths, but it becomes too short for deeper water or too long for shallow water
Solution Approach 1:
The anchor line is made dynamically adjustable in length through a reel mechanism. The line can be quickly deployed to various lengths by rotating the reel, allowing the same line to adapt to different water depths without requiring multiple lines of different lengths.
Solution Approach 2:
A single anchor line serves multiple functions across different depth requirements. By combining the reel mechanism with the line, one universal anchoring system replaces what would otherwise require multiple specialized lines for shallow, medium, and deep water scenarios.
2Productivity
If multiple decoys are placed in a carrying device, then transport capacity increases, but anchor lines become intertwined and require time to separate
Solution Approach 1:
The anchor line system is segmented into a reusable reel component and a detachable line. The line can be quickly released from the reel at the decoy, allowing anchor lines to be separated rapidly when decoys are removed from the carrying device, eliminating the time-consuming untangling process.
Solution Approach 2:
The anchor line is extracted from the decoy body and managed separately via the reel mechanism. This allows the line to be independently controlled and quickly detached, preventing entanglement with other decoys during transport while maintaining efficient transport capacity.
3Stability of the object's composition
If the head and keel project from the decoy body, then the decoy maintains proper orientation and stability, but it becomes difficult to arrange decoys in the carrying device
Solution Approach 1:
The head and keel are made movable rather than fixed. During transport, they can be retracted or positioned flush with the decoy body to facilitate compact arrangement in carrying devices. During deployment, they project outward to provide proper orientation and stability in the water.
Solution Approach 2:
The head and keel can change their spatial configuration relative to the decoy body. They transition from a projected state (providing stability) to a retracted state (facilitating storage), effectively using dimensional change to resolve the contradiction between stability and ease of arrangement.

AI summary
A decoy comprising: (a) an anchor device comprising: (i) a crank; (ii) a spool connected to the crank; and (iii) a locking member located proximate to the spool, wherein a gap separates the spool and the locking member and the gap in a locked position is sufficiently small so that the spool is prevented from rotating and the gap in a deployment position is sufficiently large so that the spool free rotates; (b) an anchor, and (c) an anchor line connecting the anchor to the spool so that the spool in the locked position assists in retracting the anchor and in the deployment position allows the anchor to deploy.
