Reciprocating Decoy Movement Device for Waterfowl Hunting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waterfowl decoys struggle to realistically simulate the complex and multiple motions of a live bird, particularly the side-to-side movement and bouncing action of a bird landing, which is crucial for effectively luring waterfowl during hunting.
Innovation Solution
A reciprocating decoy movement device featuring a base plate, swivel arm, and decoy support rod system, where a motor-driven drive shaft rotates a drive bar to swivel the arm and move the decoy support rod back and forth, combined with a flexible support rod that allows the decoy to bounce, mimicking the motion of a landing bird.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wind-dependent motion mechanisms are used, then the decoy can achieve some wing movement simulation, but the motion is unreliable and cannot consistently simulate the complex side-to-side movement and bouncing of a landing bird
Solution Approach 1:
The patent employs a dynamic mechanism where a motor-driven drive shaft rotates a drive bar that swivels a swivel arm, causing the decoy support rod to move back and forth. This dynamic mechanical system reliably produces the side-to-side movement and bouncing motion of a landing bird, overcoming the unreliability of wind-dependent approaches while maintaining manageable complexity through modular design
Solution Approach 2:
The mechanism creates periodic reciprocating motion through the rotation of the drive shaft and the swiveling of the swivel arm, producing repeated side-to-side movements and bouncing actions. This periodic action consistently simulates the flapping and landing behavior of waterfowl, providing reliable and repeatable motion patterns that wind-dependent systems cannot guarantee
2Reliability
If simple static decoys are used, then the device complexity is low, but the decoy cannot realistically simulate the multiple complex motions of a live waterfowl during landing
Solution Approach 1:
The patent divides the motion simulation system into separate functional segments: a motor-driven drive shaft, a swiveling swivel arm, and a decoy support rod. Each segment performs a specific function (rotation, swiveling, and supporting the decoy), allowing the complex motion to be achieved through coordinated simple parts rather than a single complex mechanism
Solution Approach 2:
The system transitions from a static decoy to a dynamic one by incorporating a motor-driven mechanism that actively moves the decoy support rod. This dynamic component creates the side-to-side movement and bouncing actions necessary to simulate a landing bird, significantly improving realism while keeping the overall structure relatively simple through functional segmentation

AI summary
A reciprocating decoy movement device which has a swivel arm mounted on a pivot post extending upwardly from a base plate, and a drive bar rotatably mounted on a drive shaft extending upwardly from the base plate, the drive bar having an upwardly extending drive post slidably fitted in a guide channel disposed on the underside of the swivel arm, such that rotation of the drive bar moves the drive pin through a circle while sliding in the guide channel, thereby causing the swivel arm to move reciprocally from side-to-side.
