Solution Overview

Problem

Existing decoys lack the ability to move in a controlled manner without requiring frequent reassembly, power sources, and are difficult to store in a flat configuration, leading to uncontrollable spinning in strong winds.

Innovation Solution

A decoy stake system featuring a rod, bracket, and legs that allows a flat decoy to rotate in the wind while preventing uncontrollable spinning, enabling easy relocation and storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a decoy is made stationary to maintain structural simplicity, then manufacturing complexity is reduced, but the decoy fails to attract moving animals effectively

Engineering Contradiction:

Improvestructural simplicityVSAvoidability to attract moving animals

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The decoy is designed with a rotating mechanism that allows it to change from a stationary state to a dynamic rotating state. The rotation is enabled by a bearing system and can be triggered by wind or manual activation, allowing the decoy to adapt its behavior to attract moving animals while maintaining structural simplicity when stationary.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If a motor shaft is added to enable decoy motion, then the decoy can move to attract animals, but the device becomes difficult to relocate and store

Engineering Contradiction:

Improvedecoy motion capabilityVSAvoidrelocation and storage difficulty

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The decoy system is divided into separable components: the decoy body with rotating mechanism can be detached from the stake portion. This segmentation allows the decoy to be easily relocated by simply removing it from the ground stake, while the stake remains in the ground for future use. The rotating mechanism is integrated into the decoy body itself, eliminating the need for complex external motor shafts.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The decoy utilizes rotational motion around a vertical axis rather than linear movement, allowing it to attract animals from multiple directions while remaining fixed in position. This dimensional approach to motion enables the decoy to be easily relocated by simply lifting it vertically from the stake without requiring disassembly of motion mechanisms.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If a motorized system is used for decoy motion, then continuous movement is achieved, but frequent power source recharging is required

Engineering Contradiction:

Improvecontinuous motionVSAvoidpower source recharging time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The decoy incorporates a wind-powered rotation mechanism where wind energy directly drives the rotation through aerodynamic forces on the decoy body or attached vanes. This self-service approach eliminates the need for external power sources, as the decoy automatically rotates when wind is present, converting environmental energy into motion without requiring recharging.

Inventive Principle:

Principle #25Self-service

4Adaptability or versatility

If a decoy allows free rotation in wind, then it can attract animals through motion, but it spins uncontrollably in strong winds

Engineering Contradiction:

Improvewind-driven motionVSAvoidrotation control

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The decoy incorporates a damping mechanism that provides resistance to rotation based on the rotational speed. As the decoy rotates faster in strong winds, the damping force increases to counteract the wind force, preventing uncontrollable spinning. This feedback mechanism maintains stable, controlled rotation across varying wind conditions while still enabling animal attraction through motion.

Inventive Principle:

Principle #23Feedback

AI summary

A decoy system can include a rod defining an axis of rotation, a bracket coupled to a lower end of the rod, a pair of legs coupled to the bracket, and a decoy supported on the rod and configured to rotate about the axis. The bracket can include side panels defining opposing planes. The rod, decoy, and the pair of legs can be configured to extend within the opposing planes. The bracket can include a rotational stop configured to engage a first face and an opposing second face of the decoy for preventing more than 180 degree rotation of the decoy about the axis of rotation. A method of using the decoy can include providing the decoy, inserting the pair of legs into a surface, removing the pair of legs from the surface by pulling a handle of the rod away from the surface wherein the decoy remains intact.
