Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired communication is used for electronic lock mechanisms, then system reliability is improved, but device flexibility and ease of installation deteriorate
Solution Approach 1:
The patent replaces the mechanical wired communication system with a wireless communication system using Bluetooth Low Energy (BLE) technology. The electronic lock mechanism includes a wireless communication module that transmits and receives data wirelessly, eliminating the need for physical wire connections between the lock and the control system, thereby improving installation flexibility while maintaining communication reliability
2Ease of operation
If wireless communication is implemented in electronic lock mechanisms, then device flexibility and ease of installation are improved, but communication stability may deteriorate
Solution Approach 1:
The patent introduces a mobile terminal as an intermediary device in the communication chain. The mobile terminal establishes a wireless connection with the electronic lock mechanism and relays communication through a wired connection to the control system, thereby stabilizing the wireless communication link while maintaining installation flexibility
Solution Approach 2:
The system implements feedback mechanisms where the mobile terminal and control system monitor communication quality and can adjust parameters or switch between wireless and wired modes to maintain stable communication
3Ease of operation
If wireless communication is used, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent leverages the mobile terminal's existing wireless communication capabilities (Bluetooth, Wi-Fi) that users already possess. The electronic lock mechanism integrates a wireless communication module that can work with standard mobile devices, avoiding the need for specialized complex systems while providing wireless operation convenience
