Buoyant Decoy with Motor-Propeller for Waterfowl Mimicry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional waterfowl decoys are motionless, limiting their ability to convincingly mimic live animals and attract other waterfowl effectively, as they lack the dynamic movement that live waterfowl exhibit while feeding or diving.
Innovation Solution
A buoyant decoy device equipped with a motor-actuated propeller that creates bobbing and bouncing motions, mimicking a waterfowl feeding action, with a self-righting mechanism to maintain the decoy above water and attract other waterfowl through lifelike movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional motionless decoys are used, then manufacturing is simple and cost-effective, but the decoy cannot convincingly mimic live waterfowl movement
Solution Approach 1:
The decoy is transformed from a static object to a dynamic one by incorporating a motor-driven propeller system that generates bobbing and diving motions, allowing the decoy to simulate the natural movements of live waterfowl in the water
Solution Approach 2:
The patent replaces complex mechanical linkage systems with a simpler motor-propeller configuration that achieves realistic movement through direct propulsion, reducing overall mechanical complexity while maintaining movement authenticity
2Manufacturing precision
If spinning wing decoys are used to create motion, then the decoy appears more life-like, but the structure becomes more complex and fragile
Solution Approach 1:
The patent removes the fragile spinning wing mechanism entirely and extracts only the essential function of creating water disturbance and bobbing motion, achieving realism through a more reliable propeller-based system
Solution Approach 2:
The design favors simpler, more durable components that can withstand water exposure and mechanical stress over time, prioritizing reliability while maintaining acceptable movement realism
3Manufacturing precision
If a motor-actuated propeller is added to create bobbing motion, then the decoy mimics feeding action effectively, but the device complexity increases
Solution Approach 1:
The motor-propeller assembly serves multiple functions simultaneously: it creates bobbing motion, generates diving movements, and produces water ripples, eliminating the need for separate mechanisms for each type of movement
Solution Approach 2:
The patent combines the propulsion system with the motion-generation system, where a single motor-propeller unit creates all necessary feeding-like movements through its interaction with the water and buoyant decoy body

Function Achieved in This Case
The decoy device effectively mimics the natural movement of waterfowl, creating ripples and attracting other waterfowl, enhancing the decoy's attractiveness and functionality while being robust and cost-effective to manufacture.
Implementation Method 1
a propeller to cause a floating decoy body to bob and move in the water
Implementation Method 2
a buoyant decoy device with a motor that actuates a propeller

AI summary
An at least partially buoyant decoy apparatus for use in the water is provided that mimics the look of a diving or feeding animal. The decoy comprises in various embodiments an exterior shaped at least partially in the shape of an animal, a propeller, a power source, and a motor, wherein the propeller and a power source are operationally coupled to a motor such that the powered motor is capable of acting on the propeller to create a downward thrust relative to the water line of the body of water in which the decoy resides to make the decoy apparatus move dip or dive into the water for a period of time, to be released back to the surface when the motor ceases to act on the propeller.
