Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is transmitted directly from the logic analyzer to the computer, then the computer can analyze the data, but the analysis process becomes time-consuming and complex when dealing with massive data
Solution Approach 1:
The patent segments the data transmission process into two distinct paths: a high-speed path for raw data acquisition from the probe to the logic analyzer, and a controlled path from the logic analyzer to the computer. This segmentation allows the system to handle massive data efficiently by separating the high-speed capture function from the analysis function, preventing bottlenecks in the overall process.
Solution Approach 2:
The logic analyzer acts as an intermediary device between the probe and the computer. It receives digital signals at high speed through the probe, processes and manages the data flow, and then transmits it to the computer for analysis. This intermediary role enables the system to manage massive data volumes efficiently, reducing the time and complexity of analysis while maintaining data integrity.
2Productivity
If the logic analyzer transmits data at high speed to the computer, then data analysis can be performed, but the system becomes unstable when the computer lags or transmission rates are low
Solution Approach 1:
The patent implements dynamic transmission rate adjustment where the logic analyzer can adapt its data transmission speed to the computer's processing capacity. When the computer lags or transmission rates are low, the system automatically adjusts to prevent data loss and maintain stability, while still enabling high-speed data capture when conditions permit.
Solution Approach 2:
The system incorporates buffer mechanisms that cushion against potential transmission bottlenecks before they occur. By preparing for possible computer lag or low transmission rates in advance, the logic analyzer can maintain stable operation and prevent data loss, ensuring reliable performance across varying system conditions.
3Measurement precision
If massive data is collected for performance comparison, then comprehensive analysis is possible, but the process becomes too complicated and time-consuming for manufacturers to provide performance reports
Solution Approach 1:
The patent enables preliminary data collection and organization at high speed before analysis begins. The logic analyzer captures and structures massive data volumes in advance, preparing them for efficient processing. This preliminary action reduces the complexity of subsequent analysis by having data ready in an organized format, making it feasible for manufacturers to provide comprehensive performance reports.
Solution Approach 2:
The system creates accurate digital copies of signal data from the probe through the logic analyzer to the computer. These copies preserve the original signal characteristics while enabling efficient manipulation and analysis. By working with these copied data representations rather than raw signals, the system maintains measurement precision while reducing analytical complexity.
