Laser Decoating of Multi-Glazed Windows for Local RF Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decoating technologies for multi-glazed windows are inadequate for in-situ use on windows already mounted on objects, as they require precise calibration and cannot handle varying glass panel thicknesses and coating system positions, leading to inefficiencies and inability to focus lasers properly on unknown window structures.
Innovation Solution
A decoating apparatus with a laser source and orientation means, including a rotatable mirror or galvanometer-based motor, that can be detachably fixed to a multi-glazed window using suction pads, allowing for precise control of the laser beam direction and displacement in the Z-axis to focus on the coating system without needing to displace the device along the window plane, thus enabling efficient decoating of small portions without impairing thermal performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a laser decoating system is used to remove coating system, then electromagnetic transmission is improved, but thermal performance deteriorates
Solution Approach 1:
The patent applies local quality by removing the coating system only in specific localized areas (decoated portions) rather than uniformly across the entire window surface. This selective removal allows radio waves to pass through while preserving the coating's thermal control properties in the remaining areas, thus resolving the contradiction between improving electromagnetic transmission and maintaining thermal performance.
2Productivity
If existing laser decoating apparatus is used, then coating removal is achieved, but adaptability to different window structures deteriorates
Solution Approach 1:
The patent implements dynamics by making the laser apparatus detachable and repositionable, allowing it to adapt to different window configurations. The apparatus can be removed and reattached at various positions and orientations, enabling it to handle different glass panel thicknesses and coating system positions without requiring recalibration, thus resolving the contradiction between productivity and adaptability.
3Stability of the object's composition
If laser apparatus is fixed and heavy, then stability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the laser apparatus into separable components that can be detached and reattached. This modular design allows the apparatus to be lightweight and easy to transport while maintaining stability during operation through proper mounting on the window surface, thus resolving the contradiction between stability and ease of operation.
