Three-Point Suspension for Laser Engraving Tool Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing four-point suspension system for laser engraving tools is difficult to operate, making it inefficient for adjusting the elevation and orientation of the engraving tool relative to the workpiece.
Innovation Solution
A three-point suspension system with at least two adjustable points, accompanied by a handy gauging device, allows for faster and easier adjustment of the laser's elevation and orientation, ensuring the laser remains at the correct focal point throughout the engraving process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a four-point suspension system is used to support the laser cabinet, then the structural stability is improved, but the ease of operation deteriorates due to the complexity of adjusting four points simultaneously
Solution Approach 1:
The patent removes one support point from the four-point suspension system, reducing it to a three-point system. This extraction simplifies the adjustment process by eliminating one degree of freedom while maintaining sufficient structural stability for the laser cabinet during engraving operations.
Solution Approach 2:
The patent segments the adjustment function by providing independent adjustment mechanisms for each of the three support points. This allows operators to adjust elevation and orientation more easily by manipulating individual points rather than coordinating four points simultaneously, while still achieving stable positioning.
2Measurement precision
If multiple adjustable suspension points are provided, then the precision of laser positioning is improved, but the device complexity increases
Solution Approach 1:
The patent applies local quality by making only the necessary support points adjustable (three points instead of four) and providing independent adjustment mechanisms at each point. This localized adjustment capability achieves precise laser positioning while avoiding the complexity of a fully adjustable four-point system.

AI summary
An engraving system using a laser as a tool includes a laser cabinet with a three-point suspension system for mounting the cabinet on a surface such as a table. The three suspension points are arranged in a triangle with at least one of the suspension points being either in the front center or rear center of the field of translation of the engraving tool in the xy plane. While the other two suspension points are mounted in either the left and right front corners of the field or the left and right rear corners of the field or close to those locations. Using the three triangularly arranged suspension points, at least two of which are independently adjustable in elevation, the laser cabinet can be elevated and oriented so as to maintain the plane of the tool translation field parallel to the target surface of the workpiece during an engraving operation. Where the tool is a laser, the cabinet also carries a gas laser tube and an optical system for directing the output thereof to a nozzle aimed downwardly along the z axis and equipped for programmable translation in the xy axis field.
