Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data pins are connected to enable communication, then data transfer capability is improved, but security risk increases due to potential malware intrusion
Solution Approach 1:
The system performs preliminary actions by checking onboard memory and executing handshake protocols before activating data pins. This preliminary verification ensures that only authorized devices can establish data communication, preventing malware intrusion before it can occur.
Solution Approach 2:
The microcontroller acts as an intermediary between the USB connection and the device, mediating all data and power interactions. It continuously monitors and controls pin states, enabling secure communication by filtering and validating all data traffic before it reaches the device.
Solution Approach 3:
The system implements continuous feedback by constantly analyzing data transmitted through the USB connection. The microcontroller monitors data flow in real-time and dynamically adjusts pin states based on the analyzed information, enabling the device to respond to potential security threats immediately.
2Object-affected harmful factors
If USB pins are deactivated for security, then security risk is reduced, but charging and communication functionality is limited
Solution Approach 1:
The system dynamically adjusts pin states based on the operational context and security requirements. The microcontroller can switch between different configurations (charging only, communication enabled, or both) depending on the situation, providing both security and functionality as needed.
Solution Approach 2:
The system performs periodic security checks and handshakes at regular intervals during operation. This periodic verification ensures continuous security monitoring while maintaining normal charging and communication functions between checks.
3Reliability
If microcontroller with memory checking is implemented, then security control is improved, but device complexity increases
Solution Approach 1:
The microcontroller serves multiple functions simultaneously: it manages power delivery, controls data pin activation, executes security protocols, checks onboard memory, and continuously analyzes data traffic. This multi-functionality consolidates what would otherwise require separate components into a single integrated unit.
