Solution Overview

Problem

Existing anchor installation methods in masonry construction are time-consuming and physically demanding, especially when working in tight spaces or overhead, as they require manual hammering to set anchors into concrete or masonry.

Innovation Solution

An anchor installation tool featuring an elongated member with a body and head portion, an anchor guide with a sleeve-shaped body and bore, and a retaining mechanism using a magnet and O-ring or clip to secure the anchor, allowing for percussive movement by a hammer drill to drive the anchor into the structure without manual hammering.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual hammering is used to install anchors, then the anchor can be set into the masonry material, but the process is time-consuming and physically demanding

Engineering Contradiction:

Improveinstallation speedVSAvoiduser fatigue

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The patent replaces the manual hammering mechanical system with a pneumatic or electric anchor installation tool that delivers controlled percussive forces. The tool includes a hammer mechanism that automatically strikes the anchor into the masonry material, eliminating the need for manual hammering and significantly reducing user fatigue while increasing installation speed.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The anchor installation tool is designed to perform the installation operation autonomously once positioned. The tool self-regulates the percussive force and frequency, and the anchor guide automatically maintains proper alignment, allowing the system to complete the installation without continuous manual intervention or adjustment.

Inventive Principle:

Principle #25Self-service

2Ease of operation

If manual hammering is used to install anchors overhead, then the anchor can be set into the structure, but it is very demanding on the user's body

Engineering Contradiction:

Improveoperational comfortVSAvoidinstallation efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The patent replaces the manual hammering mechanical system with a powered anchor installation tool that delivers controlled percussive forces. The tool includes a hammer mechanism that automatically strikes the anchor into the masonry material, eliminating the need for manual hammering and significantly reducing user fatigue while increasing installation speed.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If a hammer drill with beat piece is used, then the anchor can be secured into the concrete material, but the device complexity increases

Engineering Contradiction:

Improveinstallation efficiencyVSAvoidtool structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The anchor installation tool is divided into distinct functional segments: a body portion for housing the hammer mechanism, a head portion for engaging the anchor, and an anchor guide for alignment. This segmentation allows each component to perform its specific function efficiently while maintaining overall system manageability and reducing complexity compared to integrated hammer drills.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The anchor installation tool is designed to work with standard drill bits and anchors, making it compatible with existing drilling equipment and materials. The tool can be attached to various drill types and uses universal anchor configurations, reducing the need for specialized equipment while maintaining high installation efficiency.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Manufacturing precision

If an anchor guide is added to ensure proper alignment, then the anchor placement precision improves, but the device complexity increases

Engineering Contradiction:

Improveanchor alignmentVSAvoidtool components

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

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 tool simplifies and speeds up the anchor installation process, reducing user fatigue and enabling efficient anchor placement in tight spaces by eliminating the need for manual hammering and ensuring proper alignment and retention of anchors.

Implementation Method 1

The magnet is retained in the bore to enhance the retention of the anchor in the bore

Methodology Applied

Scientific EffectMagnetic retention: Magnetism

Implementation Method 2

A percussive movement is provided on the drill bit. The percussive movement drives the anchor into the structure. The percussive movement is provided by a hammer drill.

AI summary

An anchor installation tool has an elongated member with a body portion and a head portion. The body portion includes an internal bore to receive a drill bit. The head portion projects from and has a diameter smaller than the body portion. The head portion is coaxial with the body portion. An anchor guide has a sleeve-shaped body with a bore throughout the body. The bore has a portion sized to fit over the body portion and a portion to fit over the head portion. The guide slides on the body and head portions. A mechanism retains the anchor guide onto the body portion. The retaining mechanism enables sliding of the anchor guide and prohibits removal of the anchor guide from the body portion.
