Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If security software performs continuous scanning of information to be scanned, then scanning thoroughness and security detection capability are improved, but CPU resource occupancy increases causing system performance degradation
Solution Approach 1:
The patent implements periodic scanning by introducing delay durations between consecutive scans. The scanning module performs scans at scheduled intervals rather than continuously, allowing the system to balance security monitoring needs with CPU resource availability. This periodic action ensures thorough scanning coverage while preventing sustained high CPU occupancy that would degrade overall system performance.
Solution Approach 2:
The patent dynamically adjusts the delay duration between scans based on real-time CPU performance information. When CPU resources are abundant, shorter delays enable more frequent scanning. When CPU load is high, longer delays reduce scanning frequency to maintain system responsiveness. This dynamic adaptation resolves the contradiction by making scanning intensity flexible rather than fixed.
2Measurement precision
If multiple scans are performed on information to be scanned, then security detection accuracy is improved, but CPU resource consumption increases causing slow system response
Solution Approach 1:
The patent employs feedback mechanisms where the scanning module monitors CPU performance information and adjusts subsequent scan timing accordingly. After each scan, the system evaluates current CPU status and determines appropriate delay durations before the next scan. This feedback loop ensures that multiple scans are performed with sufficient spacing, maintaining detection accuracy while preventing excessive CPU consumption that would slow system response.
Solution Approach 2:
The patent determines delay durations in advance before executing multiple scans. By calculating and setting the timing schedule beforehand based on expected CPU availability, the system can plan multiple scans without causing unpredictable system slowdowns. This preliminary action allows the system to commit to a scanning schedule that balances thoroughness with performance.
3Reliability
If scanning frequency is increased to improve security monitoring, then detection capability is improved, but CPU occupancy ratio increases causing user experience degradation
Solution Approach 1:
The patent changes the timing parameters of scanning operations by introducing variable delay durations between scans. Instead of maintaining a fixed high scanning frequency, the system adjusts the time interval parameter based on CPU performance conditions. This parameter change allows the system to maintain adequate security monitoring while reducing peak CPU occupancy to acceptable levels for smooth user experience.
