Rotating Decoy Stand With Manual Teetering Motion and Adjustable Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waterfowl decoy systems require batteries and motors for horizontal movement, limiting their use in remote locations, being heavy, and having finite runtime, while also lacking effective vertical motion simulations and adjustability for different water depths and visibility.
Innovation Solution
A manually actuated decoy stand with a crossbeam and hinge system that allows for teeter-totter motion, using a string, spring, and pulley actuator to simulate waterfowl taking off and landing, with a telescoping support beam for adjustable height and range of motion, and modular design for easy transport and setup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If battery-operated motors are used to create horizontal spinning motion in decoys, then the decoys can simulate waterfowl hovering above water, but the system becomes heavy and requires frequent battery recharging
Solution Approach 1:
The patent removes the battery and motor components from the decoy system entirely. Instead of using powered motors to create motion, the invention uses manual actuation through a string-pulley mechanism that the hunter operates directly, eliminating the weight and complexity of electrical power systems while maintaining the decoy's ability to simulate waterfowl motion
Solution Approach 2:
The decoy system is designed to be manually operated by the hunter through direct physical interaction. The string-pulley mechanism allows the hunter to personally control the decoy's motion without requiring autonomous powered systems, making the system self-sufficient and eliminating dependency on batteries or external power sources
2Adaptability or versatility
If battery-operated motors are used to create horizontal spinning motion in decoys, then the decoys can simulate waterfowl hovering above water, but the system has finite runtime before battery depletion
Solution Approach 1:
The manual actuation system allows for continuous operation as long as the hunter is present and willing to operate it. Unlike battery-powered systems that have fixed runtime limits, the string-pulley mechanism can be operated indefinitely, providing unlimited duration for simulating waterfowl motion and increasing hunting opportunities
Solution Approach 2:
The system eliminates dependency on finite battery power by using the hunter's own physical energy to operate the decoy. The manual string-pulley mechanism converts human effort directly into decoy motion, ensuring continuous operational capability without runtime constraints
3Device complexity
If fixed-height decoy stands are used, then the structure is simple and stable, but the decoys have limited visibility and cannot adapt to different water depths
Solution Approach 1:
The patent replaces fixed-height stands with adjustable-height stands that can be modified to suit different hunting conditions. The stands incorporate telescoping poles or adjustable legs that allow the hunter to change the decoy height, providing adaptability to various water depths and visibility requirements while maintaining structural simplicity
Solution Approach 2:
The adjustable-height stand design allows the same decoy system to function effectively in multiple hunting scenarios and water depth conditions. By making the stand height variable, a single decoy system can adapt to different environments, eliminating the need for multiple specialized stands

Implementation Method 1
moving section includes a spring that connects between the crossbeam and support beam
Implementation Method 2
The free end of the string is removed from the longitudinal plane in which the crossbeam moves
Implementation Method 3
a hinge is provided that connects the midsection of the crossbeam to the top end of the support beam
Implementation Method 4
The support beam preferably telescopes between multiple positions so that the height of the support beam and distance of the crossbeam from the water can be adjusted
Data Source
AI summary
The present invention is a decoy system that simulates waterfowl taking off and landing with an actuator that rotates a crossbeam in an oscillating manner. The crossbeam is pivotally connected through a hinge to a support beam and holds waterfowl decoys on opposite sides of the hinge, thereby raising and lowering the decoys in a teetering motion. The crossbeam can be unitary or may be formed by a pair of arm sections that are connected by a bracket. The support beam has a telescoping section that retracts and extends relative to a fixed section and has a set of legs at the base of the support beam. A pair of stops limits the extent to which the crossbeam can rotate relative to the hinge, thereby limiting the range of travel for the distal ends of the arm section.
