Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pre-protection is applied to secured information, then information security is improved, but flexibility and adaptability to various circumstances deteriorates
Solution Approach 1:
The patent implements dynamic information protection by continuously monitoring the sensing environment and automatically adjusting protection states based on real-time conditions. The processor dynamically switches between protected and unprotected states for different information items based on detected electronic devices, resolving the contradiction between maintaining security and adapting to various usage scenarios.
Solution Approach 2:
The system establishes a feedback loop where the sensor continuously detects electronic devices in the environment, feeds this information to the processor, which then adjusts protection states accordingly. This closed-loop feedback mechanism enables automatic adaptation to different circumstances while maintaining information security when needed.
2Reliability
If real-time protection is implemented, then information security is improved, but device complexity increases
Solution Approach 1:
The patent implements self-service protection where the mobile device automatically monitors its own security environment using integrated sensors and processors. The system autonomously determines when protection is needed and applies appropriate protection states without requiring external intervention or complex manual configuration, thereby achieving real-time protection with manageable complexity.
Solution Approach 2:
The system uses universal sensing components and processing mechanisms that serve multiple functions: detecting electronic devices, determining protection needs, and managing information security. This multi-functionality reduces overall device complexity while enabling comprehensive real-time protection across various scenarios.
3Ease of operation
If manual protection activation is required, then user control is improved, but response time and real-time protection capability deteriorates
Solution Approach 1:
The patent implements preliminary action by pre-configuring protection rules and criteria in the processor. When specific electronic devices are detected, the system automatically activates protection based on pre-established conditions, eliminating the need for manual user intervention while maintaining appropriate user control over protection policies.
