Solution Overview
Problem
Existing decoating technologies for multi-glazed windows are inefficient and impractical for in-situ use, as they require precise knowledge of window structure and cannot adapt to different window configurations, leading to poor focusing and inefficient decoating, especially when mounted on stationary or mobile objects like buildings or vehicles.
Innovation Solution
A compact, lightweight laser decoating apparatus with a mounting system and orientation means that allows for flexible mounting on various window configurations, using a closing means to reduce the decoatable surface area, enabling efficient decoating without the need for complex motor systems or precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a laser decoating system is used to remove coating from multi-glazed windows mounted in situ, then electromagnetic transparency is improved, but the apparatus becomes complex and difficult to handle due to requirements for precise alignment and motor systems
Solution Approach 1:
The patent replaces complex mechanical alignment systems with a magnetic positioning system. The mounting means utilizes magnetic attraction to automatically position the laser apparatus against the multi-glazed window, eliminating the need for complex motors and precision mechanical alignment mechanisms while maintaining reliable electromagnetic transparency improvement
Solution Approach 2:
The laser apparatus is designed to self-position using magnetic attraction between the mounting means and the window frame or glass panels. This self-aligning mechanism eliminates the need for external complex positioning systems, reducing apparatus complexity while ensuring reliable coating removal for electromagnetic transparency
2Manufacturing precision
If the laser apparatus is designed for precise focusing on specific window structures, then decoating precision is improved, but the adaptability to different window configurations is reduced
Solution Approach 1:
The laser apparatus incorporates adjustable focusing mechanisms and variable parameter control that allow the system to adapt to different window configurations dynamically. The magnetic mounting system enables the apparatus to conform to different window positions and orientations, maintaining decoating precision across various multi-glazed window structures
Solution Approach 2:
The laser apparatus is designed with universal mounting capabilities that can attach to different window frames and glass configurations. The system maintains precision through adjustable parameters and magnetic positioning that adapt to various window structures, enabling the same apparatus to effectively treat different multi-glazed window types
3Reliability
If the laser beam is directed at the coating system to remove it, then electromagnetic transparency is improved, but thermal performance deteriorates due to loss of coating benefits
Solution Approach 1:
The laser apparatus is designed to remove coating only from specific local areas of the multi-glazed window where electromagnetic transparency needs improvement. By selectively treating only the necessary portions rather than the entire coating system, the apparatus maintains thermal insulation performance in the remaining coated areas while achieving the required electromagnetic transparency in the treated zones
