Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laser cleaning systems face challenges in adapting to cylindrical surfaces, such as pipes, due to their curvature, requiring constant readjustment and lacking efficient automated solutions for scanning laser beams effectively.

A laser cleaning system with a frame extendable about the outer circumference of a cylindrical pipe, featuring circumferential guide supports and a motorized system to move the laser both axially and circumferentially, allowing for controlled scanning of the laser beam across the pipe surface without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional laser cleaning systems use linear or rectangular scanning patterns, then the system can effectively clean flat surfaces, but the system requires constant readjustment and cannot efficiently clean cylindrical pipe surfaces
Solution Approach 1:
The patent applies curvature by designing the laser scanning system to follow the cylindrical geometry of the pipe surface. The scanning mechanism is configured to move in circumferential and axial directions that match the curved surface, eliminating the need for constant readjustment and enabling efficient cleaning of cylindrical surfaces.
2Productivity
If manual operation is used for laser cleaning, then the system can be simple to operate, but manual labor increases operational risks and reduces efficiency
Solution Approach 1:
The system implements automated scanning control that operates independently once configured. The motorized circumferential and axial scanning mechanisms automatically navigate the laser beam across the pipe surface without requiring continuous manual intervention, thereby increasing productivity while maintaining ease of operation through initial setup only.
3Object-affected harmful factors
If conventional cleaning methods use chemicals and abrasives, then the cleaning process is simple, but the environmental impact increases and substrate wear occurs
Solution Approach 1:
The patent replaces chemical and mechanical cleaning methods with laser-based cleaning. The laser beam removes contaminants through ablation without requiring chemicals or abrasive materials, thereby eliminating environmental harm and substrate wear while accepting the complexity of laser system implementation.
