Avian Decoy Foldable Legs and Wind-Driven Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing avian decoys are difficult to set up, prone to leg breakage during transport, and require significant space for storage, with rigid leg portions often causing issues in snowy or vegetative environments, and lack efficient wind-generated side-to-side movement mechanisms.
Innovation Solution
A standing duck or goose decoy design featuring movable leg stubs that can be folded inside the decoy body, a stake with a guide mechanism for easy setup, and directional stop means to limit rotation, allowing for wind-generated side-to-side movement about a vertical axis while preventing unwanted rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If hard bodied decoys are used with rigid leg portions, then the decoy structure is stable, but the leg portions break off during transport and drag or become tangled in snow or high vegetation
Solution Approach 1:
The leg portions are segmented from the main decoy body, allowing them to be separated into movable, foldable components that can be independently positioned or retracted, preventing breakage and tangling while maintaining structural stability
Solution Approach 2:
The leg portions are made dynamic and movable rather than fixed, allowing them to be folded inside the decoy body for transport and deployed when needed, adapting to different operational conditions without breaking or tangling
2Stability of the object's composition
If hard bodied decoys are used, then the decoy provides stable positioning, but significant space is required for transport and storage
Solution Approach 1:
The movable leg portions are nested inside the decoy body when not in use, allowing the decoy to be compacted to a smaller volume for transport and storage while maintaining full functionality when deployed
3Volume of moving object
If separate head and body portions are used for easy transport and storage, then storage space is reduced, but the user must be extra careful when attaching them to insure proper positioning
Solution Approach 1:
The attachment mechanism is pre-configured with alignment features and guide structures that automatically position the head portion correctly on the body portion during assembly, eliminating the need for careful manual alignment while maintaining compact storage
4Productivity
If windsock-type decoys are fixedly attached to stakes, then setup is quick as one piece units, but they lack the ability to rotate back and forth side-to-side about a vertical axis
Solution Approach 1:
The decoy is designed with a rotatable mounting mechanism on the stake that allows it to rotate back and forth side-to-side about a vertical axis in response to wind, combining quick one-piece setup with adaptive rotational movement capability
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 design enhances setup ease, reduces leg damage, minimizes storage space, and provides a natural, wind-driven motion that mimics real birds, improving usability and appearance in various environments.
Implementation Method 1
wind generated, side-to-side movement about a substantially vertical axis

AI summary
An avian decoy including a decoy body; a stake having an upper end for rotatably supporting the decoy body, and having a lower end for being anchored to a support surface; and a guide for guiding the upper end of the stake into proper position in the decoy body.
