Auger Support Stand Helical Coil Ground Anchor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decoy stakes for duck hunting lack stability and security, especially in soft or muddy ground conditions, as they often rely on single or dual straight spikes that fail to provide a secure anchor.
Innovation Solution
A rotary auger decoy mounting stand with a helical coil at the bottom end for screwing into the ground, combined with an S-shaped loop and crank handle for vertical support and easy rotation, providing a stable and secure attachment for decoys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If straight spikes are used for ground attachment, then the structure is simple, but the stability in soft or muddy ground is insufficient
Solution Approach 1:
The patent applies a helical coil configuration instead of straight spikes. The helical shape allows the attachment to rotate and screw into soft or muddy ground, providing superior anchoring stability compared to straight spikes that simply penetrate the surface. This curved geometry enables the attachment to engage more effectively with the ground structure.
Solution Approach 2:
The attachment structure is divided into multiple segments: a lower stake portion with the helical coil for ground insertion, and an upper stake portion that receives the decoy. This segmentation allows each part to perform its specific function optimally - the helical coil provides anchoring while the upper portion provides decoy support.
2Ease of operation
If a single-piece auger design is used, then the structure is simple, but the ease of operation for rotating into ground is reduced
Solution Approach 1:
The auger is divided into two separate portions: a lower stake portion containing the helical coil that rotates into the ground, and an upper stake portion that remains stationary and supports the decoy. This segmentation allows the lower portion to be rotated independently for ground insertion while the upper portion provides stable support, significantly improving ease of operation.
Solution Approach 2:
The lower stake portion is designed to be rotatable relative to the upper portion, allowing dynamic insertion into the ground. The clamping means enables the two portions to be fixed together after rotation, transitioning from a dynamic insertion phase to a static support phase.
3Strength
If straight spikes are used, then the manufacturing is simple, but the security anchor in soft ground is insufficient
Solution Approach 1:
The helical coil configuration provides superior anchoring strength in soft or muddy ground compared to straight spikes. The helical shape allows the attachment to screw into the ground, creating a more secure anchor that resists pull-out forces better than simple penetration.
Solution Approach 2:
The division into lower and upper stake portions with clamping means allows for modular manufacturing. Each portion can be manufactured separately and then assembled, which may simplify production while achieving the desired anchor security through the helical coil design.

AI summary
An auger support stand for holding objects such as decoys above the ground. The auger support stand includes at least one rod of longitudinal member defining a shaft. The shaft includes a helical coil at the bottom end for fixedly screwing that end of the stake into the ground. The top end of the stake has a central rod including an S-shaped handle providing a crank handle for screwing the shaft into the ground. The top distal end of the shaft includes means for supporting an object.
