Engineering Contradiction Analysis
1Loss of energy
If silicon nitride membrane or silicon based photonic crystal is used as mechanical oscillator, then conversion efficiency is improved, but manufacturing complexity increases due to requirement of high-level nano process
Solution Approach 1:
The patent replaces expensive, complex-to-manufacture silicon nitride membranes and photonic crystals with inexpensive, commercially available crystal oscillators that can be manufactured using simple machine processing. This substitution maintains functional effectiveness while dramatically reducing manufacturing complexity and cost.
Solution Approach 2:
The patent changes the fundamental parameter of the mechanical oscillator from nano-scale semiconductor structures requiring complex fabrication to macro-scale crystal oscillators manufactured by conventional machining. This parameter change enables the use of widely commercialized components with simple machine processing while achieving comparable or superior performance.
2Loss of energy
If silicon nitride membrane or silicon based photonic crystal is used as mechanical oscillator, then conversion efficiency is improved, but ease of manufacture deteriorates due to requirement of high-level nano process
Solution Approach 1:
The patent substitutes difficult-to-manufacture nanostructures with inexpensive, commercially available crystal oscillators that can be produced by simple machine processing. This substitution maintains conversion efficiency while dramatically improving ease of manufacture.
Solution Approach 2:
The patent leverages the self-contained, commercially available nature of crystal oscillators that require no complex fabrication processes. These components are designed to be easily manufactured and integrated, eliminating the need for specialized nano-processing facilities and expertise.
3Ease of manufacture
If crystal oscillator is used instead of silicon nitride membrane, then ease of manufacture is improved, but device complexity changes due to different structural configuration
Solution Approach 1:
The patent merges the crystal oscillator with the microwave resonator structure, positioning the crystal oscillator inside the resonator body. This integration simplifies the overall device configuration by combining multiple functional elements into a unified structure, reducing the number of separate components and assembly steps.
Solution Approach 2:
The patent implements a nested configuration where the crystal oscillator is positioned inside the microwave resonator body. This nesting arrangement optimizes space utilization and simplifies the external structure while maintaining the functional integrity of both components.
