Subscale Waterfowl Decoy Sizing for Closer Landing Range

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing large-sized waterfowl decoys repel waterfowl due to their remarkable visual acuity, causing them to land farther away, leading to ineffective hunting and increased wounding, and require heavier equipment and longer shots, which are less effective.

Innovation Solution

Subscale waterfowl decoys, ranging from 25% to 85% of full size, attract waterfowl closer by mimicking their visual perception, using UV paint and reduced weight for stability and ease of deployment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If large-sized decoys are used to increase visibility to waterfowl, then the decoys are more visible, but waterfowl are repelled and land farther away

Engineering Contradiction:

ImprovevisibilityVSAvoidrepulsion effect

Core Design Contradiction:

Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the size parameter of the decoys from life-sized or larger to subscale (25%-85% of full size). This parameter change resolves the contradiction by making the decoys small enough to be perceived as safe by waterfowl with remarkable visual acuity, while still maintaining adequate visibility through the use of multiple decoys in a spread and UV-enhanced paints that are visible to waterfowl.

Principle #35Parameter changes

2Quantity of substance

If larger decoys are used to attract waterfowl, then more waterfowl are attracted, but heavier equipment is required and shots must be longer

Engineering Contradiction:

Improvenumber of decoysVSAvoidequipment weight

Core Design Contradiction:

Quantity of substanceVSWeight of moving object

Solution Approach 1:

The patent inverts the conventional approach by using smaller subscale decoys instead of larger life-sized decoys. This inversion resolves the contradiction because smaller decoys weigh less, allowing hunters to carry more decoys in their spread without increasing total weight, while also reducing the distance to the hunter position.

Inventive Principle:

Principle #13The other way round (Inversion)

3Manufacturing precision

If life-sized decoys are used, then the decoys represent accurate waterfowl size, but waterfowl land at greater distances reducing hunting effectiveness

Engineering Contradiction:

Improvesize accuracyVSAvoidlanding distance

Core Design Contradiction:

Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The patent changes the size parameter from life-sized (100% scale) to subscale (25%-85% of full size). This parameter change resolves the contradiction by matching the perceived size of waterfowl in their natural environment, making them feel safe enough to land closer, while maintaining sufficient visual detail through proper proportions and UV-enhanced coloring.
