Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pan-tilt motion mechanism is used to adjust the reflection mirror, then the direction of the reflection mirror can be adjusted, but the attachment structure becomes complicated and specialized cooling devices are required
Solution Approach 1:
The patent combines the adjustment function and cooling function into a single integrated electrode structure. The electrode serves both as the mounting base for the reflection mirror and as the cooling pathway carrier, eliminating the need for separate adjustment mechanisms and cooling devices. This merging reduces structural complexity while maintaining adjustability through direct manipulation of the mirror's angular position relative to the electrode.
2Ease of operation
If a pan-tilt motion mechanism is used to adjust the reflection mirror, then the direction of the reflection mirror can be adjusted, but the attachment structure becomes complicated
Solution Approach 1:
The electrode is designed to perform multiple functions simultaneously: it serves as the electrical discharge component, the structural support for the reflection mirror, and the cooling pathway. This consolidation simplifies the manufacturing process by reducing the number of separate components that need to be fabricated and assembled, while still allowing for manual adjustment of the mirror's angular orientation.
3Ease of operation
If the reflection mirror is attached with a complex attachment structure, then the mirror can be adjusted, but specialized cooling devices are required to cool the reflection mirror
Solution Approach 1:
The electrode is designed as a multi-functional component that simultaneously provides electrical discharge, structural support for the reflection mirror, and thermal cooling pathways. By making the electrode universal in its functions, the patent eliminates the need for specialized cooling devices attached to the mirror, as the cooling is achieved through the electrode's integrated pathways that directly cool the mirror at its mounting location.
4Device complexity
If the attachment structure of the reflection mirror is simplified, then the cooling system can be simplified, but the stability of laser output and beam position may be affected
Solution Approach 1:
By integrating the mirror mounting directly onto the electrode, the patent creates a rigid and stable attachment structure. The electrode's solid structure provides a stable base that maintains precise angular positioning of the reflection mirror, ensuring stable laser output and beam position. The simplification does not compromise stability because the electrode itself provides sufficient structural rigidity and precision.
