Wheel-Guided Welding Tool Attachment for Straight Cuts and Spark Deflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Welders and cutters face challenges in maintaining a straight cut line, especially when cutting metal sheets or pipes, and in managing sparks that can cause injuries.
Innovation Solution
A disc-guided assembly is attached to the neck of a welding or cutting tool, serving as a wheeled guide to maintain a consistent cut line and a safety deflector to redirect sparks away from the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a welding or cutting tool is used without a guide attachment, then the operation is simpler and faster to set up, but the cut line cannot be maintained straight and consistent distance from part features
Solution Approach 1:
A circular disc guide attachment serves as an intermediary between the welding/cutting tool and the workpiece. The disc contacts the workpiece surface and rotates along the desired cut path, maintaining a consistent radius from the tool tip to the workpiece, thereby ensuring straight cuts and consistent distances from part features.
Solution Approach 2:
The guide attachment introduces a rotational dimension to the cutting operation. By allowing the disc to rotate along the cut path while maintaining a fixed radius, the system transforms a potentially erratic linear motion into a controlled rotational motion, ensuring geometric precision.
2Object-affected harmful factors
If no spark deflection protection is provided, then the device structure remains simple, but sparks can hit the user's face, body, or gloved hand causing injuries
Solution Approach 1:
The circular disc guide attachment performs multiple functions simultaneously: it guides the tool along the desired cut path and deflects sparks away from the user. This multi-functionality resolves the contradiction by providing spark protection without requiring a separate dedicated deflection device.
Solution Approach 2:
The disc structure, which could potentially be hit by sparks, instead serves to deflect and redirect sparks away from the user's face, body, and hands. The harmful sparks are converted into a beneficial protective function by the very structure that guides the tool.
3Ease of operation
If the cut must be made around the circumference of a length of pipe or along complex paths, then the cutting task becomes more difficult and tedious, but no specialized guide is used
Solution Approach 1:
The circular disc guide attachment enables dynamic adaptation to different cutting paths. The disc can rotate freely along the cut path, accommodating curves, circles, and complex geometries while maintaining consistent spacing from the tool tip, making operations on pipes and complex paths easier and more precise.

AI summary
An assembly removably securable to a welding apparatus or a cutting apparatus is disclosed. The assembly includes a circular disc, a clamp removably securable to either apparatus, a cylindrical member secured to the clamp, and a shaft having opposite end portions. One of the end portions is rotatably mounted to an end portion of the cylindrical member. The other of the end portions has the circular disc rotatably mounted thereto.
