Laser Torch Head Enclosure for Compact Safe Cutting Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective enclosures for laser cutting machines are bulky and costly, requiring a pallet shuttle system for loading and unloading workpieces, which increases operational time and financial expenses, and do not effectively address the hazards of laser emissions and reflections.
Innovation Solution
A protection system that encloses only the laser torch head, using a combination of top, middle, and bottom protection assemblies with interlock switches and brush assemblies to prevent laser light escape, allowing direct workpiece loading and unloading without a pallet shuttle, and reducing the machine's overall volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective enclosure covers the entire laser cutting machine, then safety protection against laser hazards is improved, but the machine volume increases and operational efficiency decreases
Solution Approach 1:
The protective enclosure is divided into multiple segments: a fixed base enclosure and a movable upper enclosure that can be independently controlled. This segmentation allows the laser head area to be enclosed for safety while keeping the workpiece loading area accessible, thereby reducing overall machine volume and improving operational efficiency without compromising safety protection.
2Reliability
If a protective enclosure covers the entire laser cutting machine, then safety protection against laser hazards is improved, but operational efficiency and cost increase due to requiring a pallet shuttle system
Solution Approach 1:
The enclosure is segmented into fixed and movable portions, allowing the workpiece loading/unloading area to remain accessible while the laser head area is protected. This eliminates the need for a pallet shuttle system, directly improving operational efficiency and reducing costs while maintaining safety protection.
Solution Approach 2:
The upper enclosure is designed to be movable rather than fixed, allowing it to be opened when workpiece loading/unloading is needed and closed during laser operation. This dynamic design enables direct access to the workpiece area, eliminating the need for automated pallet shuttle systems and improving operational efficiency.
3Reliability
If a protective enclosure covers the entire laser cutting machine, then safety protection is improved, but device complexity and cost increase
Solution Approach 1:
The protective system is segmented into a simple fixed base enclosure and a movable upper enclosure with interlock switches. This segmentation avoids the complexity of fully enclosing the machine while maintaining safety protection in the critical laser head area, thereby reducing device complexity and cost.
Solution Approach 2:
The unnecessary portions of the enclosure (covering the entire machine) are extracted/removed, keeping only the essential protective elements around the laser head. This extraction eliminates complex pallet shuttle systems and full-enclosure infrastructure, reducing device complexity and cost while maintaining adequate safety protection.

AI summary
A laser cutting tool with protective enclosure assembly for manipulating a workpiece on a movable platen includes a frame, a top protection assembly, a middle protection shield, a bottom protection assembly and a laser torch head. The top protection assembly, middle protection assembly, and bottom protection assembly are removably mounted to the frame such that they form a cavity enclosing only substantially the laser torch head.
