Threaded Drop-In Anchor Setter for One-Handed Overhead Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of drop-in anchors in masonry is challenging due to the need for two-handed operation, leading to operator exhaustion and safety risks, especially in overhead applications, as traditional tools require manual handling and can be hazardous.
Innovation Solution
A drop-in anchor setting tool with a tubular body and threaded bolt that attaches to the anchor, featuring a sliding pin with a striking head and driving head, allowing for one-handed operation and hands-free safety by remaining embedded during installation, using a central bore to facilitate the expansion of the anchor within the masonry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional two-handed operation is used to set drop-in anchors, then the operator can maintain control of the tool, but operator exhaustion and safety risks increase
Solution Approach 1:
The setting tool is designed to remain embedded in the masonry after anchor installation, serving itself by staying in place rather than requiring the operator to hold or reposition it. The tool's own weight and the anchored position provide automatic stabilization, eliminating the need for continuous manual support and reducing operator fatigue and safety risks.
2Ease of operation
If the setting tool remains embedded in masonry, then hands-free safety is achieved, but tool retrieval and reuse become challenging
Solution Approach 1:
The setting tool is designed as a separate, removable component from the drop-in anchor system. The tool remains embedded in the masonry after use, but its segmented design allows it to be independently retrieved and reused for subsequent anchor installations, separating the tool's function from permanent installation.
3Productivity
If overhead installation is performed with traditional tools, then anchor placement is achieved, but operator safety and control are compromised
Solution Approach 1:
The setting tool automatically remains embedded in the masonry after overhead anchor installation, eliminating the need for the operator to manually support or retrieve the tool from elevated positions. This self-embedding feature reduces safety risks associated with overhead work by allowing the tool to secure itself without additional operator intervention.
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
Enables efficient, safe, and cost-effective one-handed installation of drop-in anchors in various masonry materials, reducing operator fatigue and risk of injury, while being universally applicable and easy to manufacture and store.
Implementation Method 1
when the striking head is struck with a striking tool (e.g., hammer, hammer-drill or other heavy object) the plunger slides inside the central bore
Implementation Method 2
The threaded bolt is sized and configured to be screwed into internal threads of a drop-in anchor
Implementation Method 3
The threaded bolt is sized and configured to be screwed into internal threads of a drop-in anchor
Implementation Method 4
the driving head pushes an expander plug inside the drop-in anchor. Driving the expander plug further inside the drop-in anchor sets the drop-in anchor
