Rotary Auger Feeder Stand Anchoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bird and waterfowl feeder stands often fail to securely anchor to the ground, leading to instability due to wind or wear, causing the stand to fall over or the decoy to spin undesirably.
Innovation Solution
A rotary auger feeder stand with a helical coil auger and perpendicular legs that can be screwed into the ground, providing a secure and removable support system with an integral crank handle for easy installation and increased lateral stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If spikes are hammered into the ground to support the feeder stand, then the stand can be supported in a preferred position, but the stand becomes loose due to wind and wear causing it to fall over or spin
Solution Approach 1:
The patent changes the anchoring mechanism from hammered spikes to a rotary auger system that screws into the ground. This parameter change in the installation method provides superior mechanical engagement with the soil, creating a more reliable anchor that resists wind loads and prevents the stand from becoming loose or spinning during use.
Solution Approach 2:
The patent replaces the simple spike-hammering mechanical system with a rotary auger drilling system. The auger's helical flights mechanically engage the soil through rotation and threading action, creating a much stronger anchoring effect compared to passive spike insertion, thereby improving both stability and reliability.
2Reliability
If a rotary auger is used to screw into the ground for secure anchoring, then the stand becomes stable and resistant to wind and wear, but the device complexity increases
Solution Approach 1:
The patent merges the auger anchoring system, the vertical support rod, the lateral bracing legs, and the feeder mounting platform into a single integrated stand structure. This consolidation reduces the number of separate components and assembly steps, making the overall device simpler despite the sophisticated anchoring mechanism.
Solution Approach 2:
The vertical rod serves multiple functions: it provides the main structural support, acts as the axis for the auger rotation, supports the lateral bracing legs, and provides the mounting interface for the feeder. This multi-functionality reduces the need for additional components, thereby reducing overall device complexity while maintaining high reliability.
3Stability of the object's composition
If the auger is cranked until the legs bear against the ground for lateral support, then increased lateral stability is achieved, but the installation time and effort increase
Solution Approach 1:
The patent employs a dynamic installation process where the auger is rotated into the ground using crank handles, and the lateral legs are progressively deployed as the auger penetrates the soil. This dynamic sequence allows the structure to self-stabilize during installation, reducing the need for additional adjustment time and effort while achieving maximum lateral stability.

Function Achieved in This Case
The rotary auger feeder stand securely holds feeders or cameras above the ground, preventing tipping and rotation, even in challenging soil conditions, and allows for easy installation and removal.

AI summary
A feeder stand including a rotary ground auger and base holds a feeder above the ground. An upright elongated rod defines a stand supported by an auger having helical coils removably screwed into the ground. A platform such as a round disc, or wire mesh platform is supported on the top distal end of the rod. At least two opposing legs extend perpendicular to the vertical elongated rod and auger forming a base. The distal end of selected opposing legs are bent or angled upward perpendicular from the ground forming handles for rotating the auger into the ground. The portion of the legs extending outward normal to the elongated support pole provides a base bearing against the ground for increased lateral support.
