Self-Drilling Masonry Anchor for Single-Step Secure Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of installing fasteners into masonry materials is lengthy and requires multiple steps, including pre-drilling, debris removal, and careful alignment of threads, which is inefficient and time-consuming compared to working with wood.
Innovation Solution
A self-driving masonry anchor with a threaded section featuring alternating high and low threads, a double fluted drill section with an abrasive drill tip, and a hex-washer head that allows for single penetration without pre-drilling, facilitating secure fastening by pre-drilling a hole and removing debris as it installs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional multi-step fastener installation process is used, then secure fastening is achieved, but installation time and complexity increase
Solution Approach 1:
The patent combines multiple separate operations (drilling, debris removal, and fastening) into a single integrated anchor that performs all functions simultaneously. The anchor includes a drill section with flutes for debris removal and a threaded section for fastening, both integrated into one component that is installed in a single continuous rotation operation, eliminating the need for separate drilling and fastening steps.
Solution Approach 2:
The drill section with flutes performs preliminary action by removing debris during the installation process itself, before the threaded section engages with the masonry material. This preliminary debris removal action is built into the installation process rather than requiring a separate cleaning step, allowing continuous rotation without interruption.
2Manufacturing precision
If traditional multi-step process is used, then proper hole preparation is achieved, but number of steps and tool changes increase
Solution Approach 1:
The patent merges the drill section and threaded section into a single integrated anchor component. The drill section with its flutes and abrasive drill tip combines hole preparation and debris removal functions, while the threaded section provides fastening capability. This integration eliminates the need for separate drill bits and fasteners, reducing the number of tool changes and steps required.
Solution Approach 2:
The anchor serves multiple functions simultaneously: the drill section with flutes creates the hole and removes debris, the abrasive drill tip ensures proper hole preparation, and the threaded section provides secure fastening. This multi-functionality in a single component reduces device complexity and eliminates the need for multiple specialized tools.
3Productivity
If single continuous rotation is used, then installation efficiency improves, but thread alignment difficulty increases
Solution Approach 1:
The patent combines the drilling and fastening operations into a single continuous rotation process. The drill section and threaded section are integrated into one component, allowing the entire installation process to be completed in one continuous rotational motion without stopping to change tools or align separate components, thereby improving ease of operation while maintaining productivity.

Function Achieved in This Case
This solution reduces the steps and time required for fastener installation in masonry materials, ensuring secure contact and higher resistance to loosening, while allowing for continuous, smooth rotation during the fastening process.
Implementation Method 1
a drill tip, wherein the drill tip includes a material which is harder than the masonry material
Implementation Method 2
a drill section having at least two flutes for removal of masonry material debris

AI summary
A self-driving masonry anchor that includes ahead configured to receive a driving bit, a threaded section extending from the bottom of the head, a drilling section following the threaded section, and a drill tip at the end of the drilling section. The threaded section includes alternating high and low threads. The high threads include notches or serrations. The low threads are double low threads such that there are two low threads between each high thread. The drilling section includes at least two flutes for the removal of debris. The drill tip includes an abrasive material which is different than the material of the drilling section such that the drill tip and drill section predrill a hole in a masonry material for the threaded section, the threaded section fastening to the masonry material.
