Bird Decoy Multi-Axis Wing Drive Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bird decoys fail to create a realistic appearance and movement of bird wings, which are crucial for attracting live birds, as their rotary or simple up-and-down motions do not accurately simulate the flight of a live bird.
Innovation Solution
A bird decoy with a multi-axis wing movement system, comprising a pivot pin and drive system, where the wing rotates and pivots about a longitudinal axis and an oblique axis, allowing complex motion mimicking a landing bird, driven by a motor and crank mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a rotary or simple up-and-down motion mechanism is used to move the wings, then the device complexity is reduced, but the realism of wing movement deteriorates
Solution Approach 1:
The patent applies the dynamics principle by implementing multi-axis movement capability in the wing mounting assembly. The wing is mounted to rotate about a longitudinal axis and simultaneously pivot about an oblique axis, creating dynamic, multi-dimensional motion that realistically simulates bird flight patterns rather than simple rotary or up-and-down movement.
Solution Approach 2:
The patent implements another dimension by adding a second axis of movement (oblique axis pivoting) to the traditional single-axis rotary mechanism. This dimensional expansion allows the wing to move in complex three-dimensional space, achieving realistic flight simulation while maintaining manageable device complexity through modular mounting assembly design.
2Manufacturing precision
If a multi-axis wing movement system is implemented, then the realism of wing movement is improved, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the wing movement system into distinct functional components: a mounting assembly with separate pivot and oblique axes, a drive system with motor and crank mechanism, and linkage components. This modular segmentation makes the complex multi-axis system easier to manufacture, assemble, and maintain while achieving realistic wing movement.
3Manufacturing precision
If the wing is secured in a manner enabling multi-axis movement, then the realism of bird simulation is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The mounting assembly is designed with universal multi-functionality, where the same assembly structure accommodates both the pivot axis and oblique axis movements. The standardized mounting design allows the complex multi-axis functionality to be achieved through a single integrated component rather than multiple separate mechanisms, improving ease of manufacture.
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 decoy effectively simulates the realistic wing movement of a landing bird, enhancing its attractiveness to hunters by providing a more lifelike representation, thereby improving the decoy's ability to attract birds.
Implementation Method 1
The drive system includes a motor, a crank member connected to the motor and a link connected to both the wing and the crank member. Thus, as the motor rotates the crank member, the crank member drives the link to impart motion to the wing attached to the link.

AI summary
A decoy, typically used for hunting fowl, having a hollow body including a head, a tail and a pair of feet. The decoy includes a pair of wings mounted to the body of the decoy for multi-axis movement. A drive mechanism typically including an electric motor and a power source is positioned within the hollow body. A pair of crank members connect to the electric motor and extend outwardly from the body. A pair of link members connect the wings to the crank members whereby rotation of the crank members enables cyclic movement defined by up/down and fore/aft motion of the wings.
