Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If silicon micromachined waveguides are used to replace conventional machined waveguides, then manufacturing precision and frequency performance are improved, but mechanical strength and reliability deteriorate due to thin cross-sections and fragile properties
Solution Approach 1:
The patent applies composite materials by combining silicon micromachined waveguide components with a ruggedized metal encapsulation fixture. The silicon waveguide provides high-frequency performance and precision, while the metal fixture provides mechanical strength and protection. This composite structure allows the fragile micromachined waveguide to be handled and connected without breakage, resolving the contradiction between precision and strength.
2Ease of manufacture
If silicon micromachined waveguides with thin cross-sections are used, then manufacturing ease and frequency performance are improved, but susceptibility to breakage during connection increases
Solution Approach 1:
The patent implements beforehand cushioning by designing a ruggedized metal encapsulation fixture that protects the fragile silicon waveguide before connection occurs. The fixture includes protective features such as recesses, spacers, and alignment mechanisms that prevent breakage during handling and connection operations. This prior protection enables the thin-cross-section micromachined waveguide to be reliably connected without breakage.
3Adaptability or versatility
If conventional milling processes are used for waveguide fabrication, then manufacturing flexibility is maintained, but production speed and productivity deteriorate due to slow serial processing
Solution Approach 1:
The patent replaces the conventional mechanical milling process with micromachining techniques that enable faster, more precise fabrication. The micromachined waveguide components can be manufactured using specialized processes that are both flexible and high-speed, resolving the contradiction between manufacturing adaptability and production speed.
