Flapping Bird Decoy With Flexible Rod Wings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decoys rely on manual operation or mechanical means, which are unreliable and prone to failure, lacking a natural and sustained simulation of bird movement to attract hunters effectively.
Innovation Solution
A bird decoy design utilizing stiffly flexible rods threaded through slits in the wings, secured with pockets, allowing the wings to be held open and flap naturally under air currents, mimicking a real bird's flight and flapping motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual operation or mechanical means are used to move decoy wings, then the decoy can simulate bird movement, but the system becomes unreliable and requires maintenance
Solution Approach 1:
The decoy wings are designed to move automatically using natural air currents and wind forces. The stiffly flexible rod allows the wings to flap in response to environmental forces without requiring external power sources, manual operation, or complex mechanical systems. This self-service approach eliminates batteries, motors, and control mechanisms while maintaining reliable operation.
Solution Approach 2:
The patent replaces complex mechanical operation systems (motors, batteries, control circuits) with a passive mechanical structure using a stiffly flexible rod. The rod's unique properties allow it to bend and return to shape under air pressure, creating wing movement through natural physical forces rather than active mechanical actuation.
2Duration of action of moving object
If stiffly flexible rods are used to hold wings open, then wings can flap naturally under air currents, but the structure must balance rigidity and flexibility
Solution Approach 1:
The patent utilizes the unique parameter properties of stiffly flexible rods, which exhibit both rigidity and flexibility characteristics. The rod maintains structural stability to hold wings in an open position while simultaneously allowing controlled bending and flapping motion when subjected to air currents. This parameter balance enables sustained wing movement without compromising structural integrity.
