Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a training process is performed to adjust the duty cycle of the toggle signal to a reference value, then timing accuracy and data reliability are improved, but the duty cycle becomes non-uniform during the training process
Solution Approach 1:
The patent implements a feedback mechanism where the receiver monitors the duty cycle of the toggle signal and compares it to a reference value (50%). Based on this comparison, the receiver determines whether to adjust the duty cycle using a code value. This continuous monitoring and adjustment process ensures that timing accuracy is maintained while resolving the non-uniformity issue by systematically managing duty cycle transitions during training and normal operations.
Solution Approach 2:
The patent introduces dynamic adjustment of the duty cycle based on operational mode. During training mode, the duty cycle is actively adjusted using code values to achieve the reference value. During normal operation mode, the duty cycle is maintained uniformly without unnecessary adjustments. This dynamic approach allows the system to optimize timing accuracy during training while ensuring duty cycle uniformity during stable operation.
2Measurement precision
If the duty cycle is adjusted during the training process to achieve a reference value, then timing accuracy is improved, but the complexity of the system increases due to multiple modules required for adjustment and monitoring
Solution Approach 1:
The patent combines multiple functions into integrated modules. The duty adjustment module and duty monitoring module work as a unified system where the monitoring module provides feedback directly to the adjustment module. This merging of functions reduces the need for separate independent components, thereby managing system complexity while maintaining the capability to achieve precise timing accuracy through duty cycle adjustment.
3Stability of the object's composition
If multiple monitoring result values are obtained during duty cycle adjustment, then duty cycle stability is improved, but the time required for determination and processing increases
Solution Approach 1:
The patent performs preliminary comparison of monitoring result values to determine the final monitoring result value. By establishing a determination method that compares current code values with immediately previous code values and selects appropriate monitoring results in advance, the system reduces processing time during normal operation while maintaining duty cycle stability through comprehensive monitoring.
