Laser Cleaning System Linear Beam Pipe Inner Wall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current laser cleaning technology is limited in cleaning the inner walls of pipes due to a narrow cleaning range and unsatisfactory cleaning efficiency, primarily because it forms a dot spotted face with discrete laser spots, leading to gaps at joints, which restricts its application and effectiveness.
Innovation Solution
A laser cleaning system comprising a laser source, energy-transferring optical fiber, coreless motor, connection lens barrel, and a tunable focusing and reflecting mirror that adjusts between 90° and 180°, allowing for flexible operation and focusing of laser beams into linear beams to cover larger areas within pipes, ensuring seamless cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If laser beams are delivered without focusing to form a dot spotted face, then the laser can be guided by optical fibers to accessible locations, but the cleaning range is narrow and gaps at joints cause unsatisfactory cleaning effect
Solution Approach 1:
The patent changes the optical parameters by introducing focusing lenses that transform the laser beam from unfocused dot spots to focused linear stripes. This parameter change in beam geometry allows the laser to cover a larger area (improving cleaning range) while maintaining the flexibility of optical fiber delivery, thus resolving the contradiction between ease of operation and cleaning range.
2Ease of operation
If laser beams are delivered without focusing to form a dot spotted face, then the laser can be guided by optical fibers, but tiny gaps at joints among laser spots cause unsatisfactory overall cleaning effect
Solution Approach 1:
The patent changes the spatial distribution parameter of the laser beam from discrete dot spots to continuous linear stripes through focusing. This transformation eliminates the gaps between spots, ensuring complete coverage and reliable cleaning effect while preserving the optical fiber delivery advantage.
3Device complexity
If laser beams are delivered without focusing, then the setup is simple, but the overall cleaning efficiency is reduced due to narrow cleaning range and gaps at joints
Solution Approach 1:
The patent introduces focusing lenses that transform the laser beam geometry from dots to linear stripes. This parameter change increases the cleaning efficiency by expanding the cleaning range and eliminating gaps, while adding only minimal complexity to the optical system, thus achieving a favorable balance between device complexity and productivity.
