Pivoting Coupler Mechanism for Avian Spinning Wing Decoy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current avian spinning wing decoys lack the ability to mimic the multi-directional flight motion of live birds, limiting their effectiveness in attracting birds, as they are typically stationary or only capable of unidirectional spinning.
Innovation Solution
A pivoting mounting system with a flexible rod and coupler mechanism, combined with a pull chord and on/off switch, allows the decoy to move in multiple directions, either by wind or manual activation, providing a more realistic flight-like motion and adjustable deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the decoy is attached to a stationary rigid pole stake, then the decoy is held in a stable stationary position, but the decoy cannot mimic the multi-directional flight motion of live birds
Solution Approach 1:
The patent replaces the stationary rigid pole with a dynamic mounting system comprising a flexible rod and pivoting coupler mechanism. The flexible rod allows the decoy to move and change direction dynamically, while the pivoting coupler enables multi-axis rotation. This dynamic structure mimics the natural flight motions of live birds while maintaining operational stability through controlled flexibility.
Solution Approach 2:
The mounting system is divided into separate functional components: a stake for ground anchoring, a flexible rod for elevation and primary movement, and a pivoting coupler mechanism for directional control. This segmentation allows each component to contribute specifically to the overall motion capability while maintaining structural integrity and stability.
2Productivity
If the decoy is made stationary on a rigid pole, then the structure is simple and stable, but the decoy lacks realistic flight-like motion to attract birds effectively
Solution Approach 1:
The dynamic mounting system with flexible rod and pivoting coupler creates realistic flight-like motions that significantly enhance the decoy's attractiveness to birds. The added complexity of these mechanical components is justified by the substantial improvement in operational effectiveness and bird attraction capability.
3Ease of operation
If a pull chord mechanism is added to enable manual activation, then the decoy can be deployed and retrieved easily, but the device complexity increases
Solution Approach 1:
The pull chord mechanism is designed to work with the existing flexible rod and coupler system, allowing the user to deploy and retrieve the decoy through simple manual pulling actions. The system leverages the inherent flexibility and pivoting capability already present in the mounting structure, minimizing additional complexity while maximizing ease of operation.
