Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an extra phase jump meter is used to detect phase jump in microwave communications devices, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent uses frequency control words as an intermediary to detect phase jumps. Instead of directly measuring phase jump with dedicated equipment, the system measures frequency control words that are proportional to the intermediate frequency signal, and infers phase jump information from these measurements. This intermediary approach enables phase jump detection without requiring direct phase measurement equipment.
Solution Approach 2:
The patent creates a copy of the phase jump information through frequency control words. Rather than measuring the actual phase jump directly, the system measures frequency control words that contain proportional information about the phase jump, effectively creating a measurable copy of the phenomenon that can be analyzed without complex direct measurement equipment.
2Measurement precision
If an extra phase jump meter is deployed for each microwave communications device, then measurement precision is improved, but productivity and detection efficiency deteriorate
Solution Approach 1:
The patent makes the frequency control word measurement system multi-functional. The same measurement infrastructure that normally operates for frequency control purposes is also used for phase jump detection. This universal approach allows phase jump detection to be performed alongside normal operations without requiring dedicated detection equipment for each device, thereby maintaining high detection efficiency.
Solution Approach 2:
The system performs self-service detection by utilizing its own existing frequency control word measurements for phase jump detection. Rather than requiring external dedicated detection equipment, the microwave communications device uses its own operational data (frequency control words) to detect phase jumps, eliminating the need for separate detection infrastructure.
3Measurement precision
If traditional phase jump detection methods are used, then measurement precision is improved, but ease of operation deteriorates due to requiring additional dedicated equipment
Solution Approach 1:
The patent merges phase jump detection functionality with the existing frequency control system. By combining these two functions into a single measurement and analysis process, the system eliminates the need for separate dedicated detection equipment and procedures. The frequency control words serve dual purposes: maintaining frequency control and enabling phase jump detection, thereby simplifying operations.
