Square Drive Anchor Adapter for Powered Helical Anchor Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing helical anchors require manual installation, which is physically demanding and time-consuming, and lack standard connections for powered tools, making reuse and reclamation inefficient.
Innovation Solution
An adapter tool that connects to helical anchors, allowing standard connections with powered tools, ensuring concentric alignment and easy installation/removal, and can withstand torsional forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual installation method is used, then physical effort is required, but installation time is reduced and simplicity is maintained
Solution Approach 1:
The adapter tool serves as an intermediary device that connects the helical anchor to powered rotational tools. It has a square drive interface that accepts standard powered tools while internally engaging the helical flight of the anchor, enabling powered installation without modifying the anchor itself.
2Productivity
If adapter tool is added to enable powered installation, then installation efficiency is improved, but device complexity increases
Solution Approach 1:
The adapter tool is designed with a universal square drive interface that is compatible with standard powered rotational tools (impact wrenches, drills, ratchet wrenches). This allows a single adapter design to work with multiple different prime mover types, reducing the need for multiple specialized tools.
Solution Approach 2:
The adapter tool has a telescoping or nested structure that allows it to be compact when not in use. The square drive interface can be retracted or nested within the body of the adapter, reducing its overall length for easy storage and handling.
3Power
If clearances are minimized for torsion transmission, then power transmission efficiency is improved, but tool connection and disconnection becomes difficult
Solution Approach 1:
The adapter tool separates the connection interface (square drive) from the anchor engagement mechanism (helical flight interface). This segmentation allows the square drive portion to have tight clearances for efficient torsion transmission while the anchor engagement portion maintains sufficient clearance for easy installation and removal.
Solution Approach 2:
The adapter tool incorporates dynamic elements such as spring-loaded fingers or adjustable clamp arms that automatically engage with the helical flight when axial force is applied during installation. During removal, reversing the axial force releases the engagement, allowing easy disconnection without requiring precise manual adjustment of clearances.
