Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users without security expertise manage information devices in diverse networks, then ease of operation is improved, but security reliability deteriorates because users cannot recognize or adjust security settings when network environment changes
Solution Approach 1:
The information processing apparatus automatically detects network environment changes by monitoring packet information and configuration information, and autonomously adjusts security settings without requiring user intervention. The system serves itself by performing change detection and security configuration adjustments automatically, eliminating the need for users to manually recognize or adjust settings when network environments change.
Solution Approach 2:
The system continuously monitors network packet information and configuration information to detect changes in network environment. Based on this feedback, the system automatically adjusts security settings to match the detected network environment, creating a closed-loop control system that adapts to changing conditions without user input.
2Reliability
If security settings are manually adjusted by users, then security reliability is improved, but device complexity increases because users must recognize network changes and manually configure settings
Solution Approach 1:
The information processing apparatus performs automatic change detection and security setting adjustment without requiring user involvement. The system monitors packet information and configuration information, detects network environment changes, and autonomously updates security settings, thereby maintaining high security reliability while avoiding the complexity of manual user configuration.
Solution Approach 2:
The patent replaces the mechanical process of manual user configuration with an automated information-processing system. Instead of requiring users to manually recognize and configure security settings, the system uses automated detection mechanisms that monitor network packets and configuration data to trigger appropriate security responses.
3Measurement precision
If packet information is continuously acquired for network change detection, then measurement precision is improved, but use of energy increases due to continuous monitoring and processing
Solution Approach 1:
The system acquires packet information periodically rather than continuously, monitoring for specific changes in network environment. The apparatus detects changes by comparing packet information at different time points, which reduces energy consumption compared to continuous acquisition while maintaining sufficient measurement precision to detect network environment changes.
Solution Approach 2:
The system performs preliminary change detection using configuration information before initiating full packet information acquisition. By first checking configuration information for indicators of network environment changes, the system can trigger targeted packet monitoring only when necessary, reducing overall energy consumption while maintaining detection accuracy.

AI summary
An information processing apparatus connected to a network comprises detecting, as first processing, first change in a network environment based on configuration information of the network, acquiring packet information related to one or more packets among a plurality of packets transmitted and received in the network, and detecting, as second processing, second change in the network environment based on the packet information, wherein it is started to acquire the packet information if the first change in the network environment is detected by the first processing. The information processing apparatus can detect changes in the network environment with high accuracy without having to constantly acquire the packet information.
