Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual PING detection is used to check network connectivity, then network reliability between two devices can be determined, but the detection process is time-consuming and cannot evaluate the entire network efficiently
Solution Approach 1:
The patent combines multiple PING detection operations into a single unified detection process. Instead of manually detecting each network device separately, the system integrates detection across multiple network devices simultaneously by establishing a detection network where devices cooperate to evaluate overall network reliability, thereby improving detection speed while maintaining accuracy
Solution Approach 2:
The patent creates a multi-functional detection system that can evaluate network reliability across different network devices and scenarios. The detection apparatus can adaptively select detection objects and methods based on network conditions, making the system universally applicable to various network configurations rather than being limited to single-device detection
2Reliability
If manual offline PING measurement is performed, then network connectivity can be checked, but the detection requires human intervention and cannot automatically evaluate multiple network devices
Solution Approach 1:
The patent implements self-service detection where network devices automatically perform reliability assessment without manual intervention. The detection apparatus automatically selects detection objects, sends detection packets, collects responses, and generates reliability evaluations. Network devices participate actively in the detection process, making the system self-sufficient and eliminating the need for human operators to manually execute each detection task
Solution Approach 2:
The patent incorporates feedback mechanisms where detection results are automatically collected and used to adjust subsequent detection operations. The system receives feedback from network devices regarding packet delivery status and uses this information to continuously refine reliability assessments, enabling automatic adaptation and improvement of detection accuracy without human intervention
3Measurement precision
If PING is used to detect network connectivity between two devices, then reliability of that specific channel can be determined, but the entire network including multiple devices cannot be evaluated
Solution Approach 1:
The patent segments the network into multiple detection channels or paths for individual evaluation. Instead of treating the entire network as a single entity, the system divides it into manageable detection units (individual network devices or channels) that can be assessed separately. This segmentation allows comprehensive coverage of the entire network while maintaining precise measurement of each segment's reliability
Solution Approach 2:
The patent extends detection from a single-dimensional point-to-point channel assessment to multi-dimensional network evaluation. By introducing additional dimensions such as multiple network devices, various transmission paths, and different detection perspectives, the system achieves comprehensive network-wide reliability assessment while preserving detailed channel-level measurement precision
