Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic network connection is used, then connection convenience is improved, but security risk increases due to susceptibility to interference from neighboring networks
Solution Approach 1:
The patent introduces a mobile terminal as an intermediary device between the electronic device and the network. The mobile terminal receives the network key from the user and relays it to the electronic device, preventing direct exposure to neighboring network interference while maintaining automatic connection convenience.
Solution Approach 2:
The patent applies different transmission power levels in different connection phases. During the discovery phase, higher transmit power is used for broader detection, while during the key exchange phase, reduced transmit power is used to limit signal range and prevent neighboring network interference, thus improving security locally.
2Reliability
If SoftAPP network connection scheme is used, then security is improved through manual key entry, but operational complexity increases
Solution Approach 1:
The patent enables the electronic device to automatically receive and process the network key through the mobile terminal without requiring manual input. The system performs self-service key exchange, eliminating the need for users to manually enter passwords while maintaining security through encrypted communication channels.
Solution Approach 2:
The mobile terminal serves as an intermediary that automates the key transfer process. Instead of requiring manual key entry, the mobile terminal receives the key from the user and automatically transmits it to the electronic device, reducing operational complexity while maintaining the security benefits of manual key management.
3Reliability
If transmit power is reduced during key exchange, then security against neighboring network interference is improved, but connection range decreases
Solution Approach 1:
The patent dynamically adjusts transmit power based on the connection phase. During initial discovery, higher power is used to ensure broad coverage. During the sensitive key exchange phase, power is reduced to limit signal range and prevent interception by neighboring networks. After connection is established, power can be increased again for normal operation.
Solution Approach 2:
The patent performs preliminary actions in a specific sequence: first establishing connection parameters and protocols, then reducing transmit power before the actual key exchange occurs. This preliminary setup ensures that when reduced power is applied, the connection framework is already in place, maintaining reliability while improving security.
