Waterfowl Decoy Motive Device With Synchronized Circular Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waterfowl decoy deployment systems fail to exhibit natural motion on the water's surface, lacking synchronization among decoys, which is crucial for attracting wild waterfowl.
Innovation Solution
A thrust bar system with electric motor-driven propellers induces a circular swimming motion to tethered decoys, using a hub and extendable arms to simulate natural duck movements, powered by a submerged battery or remote power source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If individual motive devices are used on each decoy, then each decoy can move independently, but the motion does not appear natural to ducks since natural duck groups exhibit synchronized movements
Solution Approach 1:
The patent merges multiple individual decoy motions into a single coordinated system. A central hub with radially extending arms connects multiple decoys, and a single thrust device rotates the entire hub assembly, causing all decoys to move in synchronized circular patterns that mimic natural duck flock behavior.
Solution Approach 2:
The central hub serves multiple functions: it acts as a structural support for radial arms, a rotation mechanism for synchronized motion, and a distribution point for tethered decoys. The thrust device provides universal propulsion for the entire decoy array rather than individual propulsion for each decoy.
2Reliability
If a single thrust device rotates the hub and arms, then synchronized circular motion is achieved, but the system complexity increases compared to individual motive devices
Solution Approach 1:
The system is segmented into modular components: a central hub, multiple radial arms, tether connections to decoys, and a thrust device. This segmentation allows the complex synchronized motion function to be achieved through simple rotational movement of the hub, which naturally distributes motion to all arms and attached decoys.
3Ease of operation
If decoys are tethered to extendable and retractable arms, then deployment and retrieval are facilitated, but the decoys do not exhibit natural motion while floating on the water surface
Solution Approach 1:
The system transitions from a static tethered configuration to a dynamic rotating configuration. The hub and arms remain tethered for easy deployment and retrieval, but the thrust device introduces dynamic rotational motion that causes the decoys to move in realistic circular patterns, combining the benefits of both static and dynamic configurations.
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 system effectively mimics natural duck swimming, enhancing the attractiveness of decoys to wild waterfowl by providing synchronized motion and natural appearance.
Implementation Method 1
A motive system for a waterfowl decoy deployment system includes a thrust bar system that includes a plurality of electric motor-driven propellers disposed in substantially opposite directions
Implementation Method 2
The thrust bar system uses a plurality of small electric motor-driven propellers to induce a substantially circular swimming motion to a tethered duck decoy system
Data Source
AI summary
A waterfowl decoy deployment system includes a thrust device and a hub coupled to the thrust device. The waterfowl decoy deployment system also includes a plurality of arms coupled to the hub such that the plurality of arms extend radially outward from the hub. The thrust device is configured to rotate about an axis to induce a substantially circular motion to the hub and the plurality of arms.
