Solution Overview

Problem

Conventional migratory bird decoys relying on battery-operated motion decoys are cumbersome and environmentally unfriendly, particularly for hunters who prefer traditional methods or have to transport bulky gear, as they require power sources and are not appealing to 'purist' or environmentalist hunters.

Innovation Solution

A wind-actuated migratory bird decoy wing assembly that converts static decoys into effective, motion-simulating decoys using an elongate shaft and flexible flag mounted on a strap, allowing flapping movement without a power source, appealing to hunters who prefer environmentally friendly and lightweight options.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If battery-operated motion decoys are used to simulate bird movement, then hunting effectiveness is improved, but device complexity and weight increase due to power source requirements

Engineering Contradiction:
Improvehunting effectivenessVSAvoidpower source requirements
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent removes the battery power source from the decoy system entirely, extracting the harmful element (complexity and weight of power requirements) while preserving the beneficial effect (bird movement simulation). The wind-actuated mechanism replaces electronic motors, eliminating all associated complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The decoy system uses wind energy from the natural environment to power the flapping motion, making the system self-sufficient without external power sources. The wind vane and shaft assembly automatically convert wind energy into wing-flapping motion, serving itself without batteries or motors.

Inventive Principle:
Principle #25Self-service

2Reliability

If battery-operated motion decoys are used to simulate bird movement, then hunting effectiveness is improved, but portability deteriorates due to bulky gear

Engineering Contradiction:
Improvehunting effectivenessVSAvoidportability
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

The patent extracts the heavy battery and motor components from the decoy system, replacing them with lightweight wind-catch surfaces and simple mechanical linkages. This dramatically reduces the weight and bulk of the decoy while maintaining the motion simulation capability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

By using wind energy from the environment rather than carrying heavy batteries, the system achieves portability without sacrificing motion simulation effectiveness. The wind-powered mechanism is inherently lighter than battery-operated alternatives.

Inventive Principle:
Principle #25Self-service

3Reliability

If battery-operated motion decoys are used, then motion simulation is achieved, but environmental friendliness deteriorates

Engineering Contradiction:
Improvemotion simulationVSAvoidenvironmental impact
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent converts the harmful reliance on batteries and electronic waste into a beneficial wind-powered mechanical system. By harnessing wind energy, the system eliminates battery disposal issues and electronic pollution while maintaining effective motion simulation for hunting.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The wind-actuated mechanism uses free energy from the environment, eliminating the need for consumable batteries and reducing environmental impact. The mechanical flapping system requires no electronic components that would become waste.

Inventive Principle:
Principle #25Self-service

4Device complexity

If static decoys are used to lure birds, then simplicity is maintained, but hunting effectiveness deteriorates due to lack of motion simulation

Engineering Contradiction:
ImprovesimplicityVSAvoidhunting effectiveness
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent transforms the static decoy into a dynamic system by adding wind-actuated flapping wings. The simple mechanical connection between the wind vane, shaft, and wing assembly allows natural wind to create realistic flapping motion, enhancing hunting effectiveness while maintaining overall system simplicity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The shaft and wind vane assembly act as intermediaries that convert wind energy into wing flapping motion. This simple mechanical intermediary system bridges the gap between static decoy simplicity and dynamic motion simulation effectiveness.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A migratory bird decoy wing assembly for use with a migratory bird decoy includes an elongate shaft extending in a straight line between a first end and an opposite second end and a first flexible flag. The first flexible flag is adapted to be flappingly displaceable relative the elongate shaft. The migratory bird decoy wing assembly also includes an elongate shaft mounting device constructed to removably mount the elongate shaft on a body of the migratory bird decoy so that the elongate shaft extends perpendicular to the surface of the migratory bird decoy body and flapping movement of the first flexible flag produced by wind simulates the movement of a bird flapping its wing.
