Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual operation on smartphone is required to establish Bluetooth connection and unlock door-lock, then electronic locking system provides keyless unlocking capability, but unlocking time becomes longer and convenience deteriorates compared to traditional mechanical lock
Solution Approach 1:
The system performs preliminary actions by automatically establishing Bluetooth connection and sending unlock commands before the user needs to manually operate. The mobile device automatically connects to the door-lock device and transmits unlock instructions, eliminating the need for users to wait for manual connection establishment, thus reducing unlocking time while maintaining keyless capability
2Adaptability or versatility
If manual operation on smartphone is required to control door-lock device, then electronic locking system enables remote control functionality, but ease of operation deteriorates because user must directly operate smartphone
Solution Approach 1:
The system implements self-service by enabling the mobile device to automatically perform connection and unlock operations without requiring user intervention. The door-lock device and mobile device automatically establish connection and execute unlock commands, making the system serve itself rather than requiring continuous user operation, thereby improving ease of operation while preserving remote control capability

AI summary
A door-lock control method adopted by a door-lock device and a computer program is present. The method comprises: broadcasting a connecting message in a WPAN at the door-lock device; controlling a mobile device to establish a connection with the door-lock device via the WPAN when receiving the connecting message at the computer program; sending an unlocking command via the connection at the computer; and unlocking a door-lock thereon when receiving the unlocking command at the door-lock device. This application can omit the operations which the householder needs to do manually on the mobile device or the door-lock device, and effectively improves the convenience of use and reduces the waiting time of completing unlocking the door-lock.
