Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If quartz crystal resonating technology is used to generate clock signal for high speed data transmission, then transmission precision is improved, but cost increases
Solution Approach 1:
The patent replaces expensive quartz crystal resonators with a cost-effective frequency tracking mechanism that uses software-based frequency adjustment and a low-cost frequency generation circuit. This approach uses cheaper components that can be dynamically adjusted to achieve the required transmission precision without relying on expensive precision hardware.
Solution Approach 2:
The patent dynamically adjusts the frequency generation parameters through a frequency tracking circuit that continuously monitors and modifies the conversion parameter based on the frequency difference between receiving and target signals. This allows the system to maintain transmission precision by adapting parameters rather than relying on fixed high-precision hardware like quartz crystals.
2Measurement precision
If frequency tracking mechanism is implemented to adjust conversion parameter dynamically, then transmission accuracy is maintained, but device complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the frequency tracking circuit continuously monitors the frequency difference between the receiving frequency signal and target frequency signal, then adjusts the conversion parameter accordingly. This closed-loop feedback system maintains transmission accuracy by automatically compensating for frequency variations without requiring complex manual intervention or overly sophisticated hardware.
Solution Approach 2:
The patent replaces the mechanical/quartz crystal-based frequency generation system with an electronic/software-based frequency tracking system. This substitution uses digital signal processing and programmable frequency adjustment to achieve the same or better precision while reducing hardware complexity and cost.
