Auger Anchor With Square Shaft For Secure Watercraft Holding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchor devices for vessels lack efficient and user-friendly mechanisms to securely anchor objects to the ground, particularly in aqueous environments, as they often require mechanical fasteners and can be prone to dislodgment due to external forces like wind and waves.
Innovation Solution
A shaft-based anchor device with a handle and auger blades that can be rotated to bore into the ground, featuring a square cross-section for torque transfer without mechanical fasteners, and a detachable handle for easy operation, allowing secure anchoring of objects with reduced lever arm and improved usability in water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional anchors use mechanical fasteners to secure objects to the ground, then the anchoring strength is improved, but the device complexity and ease of operation deteriorate
Solution Approach 1:
The patent removes mechanical fasteners from the anchor system, extracting the complexity of assembly and disassembly while maintaining anchoring strength through the auger's direct engagement with the ground via helical blades that screw into the substrate
2Stability of the object's composition
If traditional anchors use fixed handles, then the structural stability is improved, but the ease of operation in aqueous environments deteriorates
Solution Approach 1:
The handle is divided into a main body and a detachable grip portion, allowing the user to easily attach and detach the grip for operation in water while maintaining the structural integrity of the main handle body when assembled
3Ease of operation
If anchors are designed with long lever arms for operational leverage, then the ease of operation is improved, but the risk of dislodgment due to external forces increases
Solution Approach 1:
The anchor features a concentrated mass at the distal end of the shaft, creating local weight concentration that provides stability and resistance to dislodgment, while the handle provides sufficient leverage for operation without requiring an excessively long lever arm
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 anchor device provides a stable and secure anchoring system that is easy to use and maintain, with reduced risk of dislodgment and improved safety, as it creates a static anchor point without the need for mechanical fasteners, making it suitable for various applications including watercraft and land-based objects.
Implementation Method 1
The shaft, the first auger blade, and the second auger blade form an auger that bores into the ground upon rotation of the shaft
Implementation Method 2
The first auger blade may extend circumferentially around the shaft in a helical configuration
Implementation Method 3
The top end of the shaft may have a square cross-section... The handle member may have a square cross-section that matingly engages with the square cross section of the top end of the shaft

AI summary
An anchor device and method for safely and reliably securing watercraft to the bed of a body of water is provided. The anchor device may include a handle member with detachable components and an auger. The auger may be bored into the ground upon rotation of the handle member and then detached from the handle member by lifting the handle member vertically. The auger may include a shaft with a square cross-section and a pointed bottom end. Two auger blades, separated by an axial gap, may be attached to the shaft. Each auger blade may extend circumferentially around the shaft in a helical configuration.
