Mounted Multi-Glazed Window Laser Decoating With Localized Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decoating technologies for multi-glazed windows are inefficient and impractical for windows already mounted on objects, as they require precise calibration and cannot handle unknown structures or small decoating portions without damaging the coating system or being too heavy and complex for in-situ use.
Innovation Solution
A decoating apparatus with a laser source, motors for displacement, and orientation means, including a rotatable mirror or galvanometer-based motor, synchronized to minimize exposure time and prevent overheating, along with suction and rigid pushing means for stabilization, allowing precise decoating on any multi-glazed window regardless of structure or location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a laser decoating system is used to remove coating portions, then electromagnetic transmission is improved, but the coating system properties are impaired
Solution Approach 1:
The patent applies local quality by removing coating only in specific localized areas (segments or lines) rather than uniformly across the entire coating surface. This selective removal pattern creates frequency selective surfaces that allow electromagnetic transmission while preserving the coating's solar control properties in the remaining areas.
Solution Approach 2:
The patent uses partial action by removing only a portion (1-3%) of the total coating surface area. This minimal decoating is sufficient to create the necessary electromagnetic transmission pathways while maintaining the overall integrity and solar control functionality of the coating system.
2Adaptability or versatility
If existing decoating apparatus is used on mounted windows, then the apparatus is heavy and complex, but it cannot handle unknown window structures
Solution Approach 1:
The patent inverts the conventional approach by using a lightweight, simple apparatus that can be easily mounted on the window surface, rather than a heavy, complex system that attempts to process the window from outside. This inversion enables adaptability to various window structures while reducing device complexity.
Solution Approach 2:
The patent replaces complex mechanical positioning and calibration systems with a simpler system that uses the window's own structure for mounting and alignment. This substitution reduces device complexity while maintaining or improving adaptability to different window configurations.
