Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If digital signal processing methods are used for data classification in portable devices, then classification capability is achieved, but power consumption increases and computing resources are exhausted
Solution Approach 1:
The patent replaces digital signal processing with analog signal processing using nanoscale resonators. The resonators physically respond to input signals through mechanical resonance, converting electrical signals into mechanical vibrations and back to electrical signals. This analog approach eliminates the need for complex digital computations, thereby reducing power consumption while maintaining classification capability.
Solution Approach 2:
The patent changes the operating parameters by using nanoscale resonators with specific resonant frequencies instead of digital processors. The resonators are tuned to resonate at particular frequencies, allowing them to selectively respond to input signals. This parameter change enables efficient analog signal processing that consumes less power compared to digital processing.
2Reliability
If digital signal processing methods are used for data classification in portable devices, then classification capability is achieved, but computing resources are limited
Solution Approach 1:
The patent replaces digital signal processing circuits with a physical resonator system. The nanoscale resonators perform signal processing through their inherent mechanical properties, eliminating the need for complex digital hardware. This substitution reduces computing resource requirements while maintaining the ability to classify data through analog signal transformation.
Solution Approach 2:
The resonators perform signal processing autonomously through their physical resonance characteristics. The system leverages the natural resonant properties of the nanoscale structures to automatically filter, amplify, and transform signals without requiring external digital processing control. This self-service approach reduces the burden on computing resources.
3Use of energy by moving object
If analog data processing using nanoscale resonators is implemented, then power consumption is reduced, but device complexity increases due to nanoscale fabrication requirements
Solution Approach 1:
The patent segments the resonator structure into distinct functional components: the nanoscale resonating elements, the substrate, and the electrical connection interfaces. This segmentation allows for modular fabrication where each component can be optimized and manufactured separately, reducing the overall manufacturing complexity despite the nanoscale dimensions.
Solution Approach 2:
The nanoscale resonator structure serves multiple functions: it acts as a signal sensor, a frequency-selective filter, and an signal amplifier simultaneously. This multi-functionality reduces the need for separate dedicated components, thereby simplifying the overall device architecture and manufacturing process while maintaining low power consumption.
