Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If data are acquired at very high speed and stored in buffer, then data acquisition speed is improved, but data integrity deteriorates when processing unit is overwhelmed
Solution Approach 1:
The patent implements a feedback mechanism where the processing unit monitors its own workload and sends status information back to the acquisition unit. When the processing unit is busy, it triggers a pause in data acquisition, preventing buffer overflow and data loss. This closed-loop control ensures data integrity while maintaining high acquisition speeds during available capacity.
Solution Approach 2:
The system dynamically adjusts the data acquisition rate based on real-time processing capacity. The acquisition unit can switch between high-speed mode and paused mode, making the system flexible and adaptive to varying processing loads, thus preventing data loss without sacrificing overall acquisition efficiency.
2Measurement precision
If acquisition signal period changes due to environmental influence, then measurement accuracy is improved, but system stability deteriorates
Solution Approach 1:
The patent employs temperature compensation by detecting temperature changes and adjusting the acquisition parameters accordingly. When temperature varies, the system modifies the acquisition period to compensate for thermal drift in the circuit, maintaining accurate signal period measurement while adapting to environmental conditions.
Solution Approach 2:
The patent introduces a standard signal as an intermediary reference. By comparing the acquisition signal period against this stable standard, the system can detect and correct period deviations caused by environmental factors, ensuring measurement accuracy without compromising system stability.
