Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If frequency measurement is performed externally using related art methods, then frequency measurement capability is achieved, but measurement complexity and time consumption increase significantly
Solution Approach 1:
The patent merges the frequency measurement function into the oscillator device itself by integrating a measurement unit that counts oscillation cycles internally. This eliminates the need for complex external measurement equipment and simplifies the overall measurement process while maintaining accurate frequency measurement capability.
Solution Approach 2:
The patent introduces a measurement unit as an intermediary component within the oscillator that acts as a bridge between the oscillation control circuit and external systems. This measurement unit internally counts oscillation cycles and provides measurement results through a simple interface, mediating between the complex internal oscillation process and the simple external measurement requirement.
2Measurement precision
If frequency measurement is performed externally for multiple oscillators, then frequency data is obtained, but measurement time and operational efficiency decrease
Solution Approach 1:
The patent enables each oscillator to perform self-measurement of its frequency through an integrated measurement unit. This self-service capability allows multiple oscillators to be measured simultaneously without requiring external measurement resources for each individual oscillator, dramatically improving measurement efficiency and productivity.
Solution Approach 2:
The measurement unit continuously counts oscillation cycles in advance and stores the cycle count data internally. When measurement is needed, the pre-counted data is immediately available through the interface, eliminating the need for real-time external measurement and enabling rapid retrieval of frequency information.
3Measurement precision
If external measurement equipment is used for each oscillator, then frequency measurement is possible, but device simplicity and ease of operation are reduced
Solution Approach 1:
The patent combines the measurement function directly into the oscillator device, merging what were previously separate entities (oscillator and measurement equipment) into a single integrated unit. This integration dramatically simplifies operation as users no longer need to set up or operate complex external measurement equipment for each oscillator.
