Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Intelligent locks and keys face challenges in secure and efficient data communication, particularly in ensuring that only authorized keys can operate the lock and that data transmission is both secure and flexible, accommodating various communication standards and protocols.
Innovation Solution
The implementation of a lock and key system with a controller, data storage, and dual data communication ports, where the controller performs validation procedures and encrypts data communication, using protocols like USB, NFC, and Bluetooth Low Energy, to ensure secure and flexible operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single data communication port is used in intelligent locks, then the device complexity is reduced, but the adaptability to different communication standards and protocols deteriorates
Solution Approach 1:
The data communication frontend is segmented into multiple independent data ports (first data port and second data port), each capable of supporting different communication protocols. This segmentation allows the lock to accommodate various communication standards simultaneously without increasing overall system complexity, as each port can be configured independently for specific protocol requirements.
Solution Approach 2:
The data communication frontend is designed with multi-functional capability through multiple data ports that can handle different communication protocols (e.g., USB, NFC, Bluetooth). This universal design enables a single lock device to serve multiple communication needs without requiring separate specialized hardware for each protocol.
2Reliability
If data communication is conducted without validation procedures, then the ease of operation is improved, but the security of the lock system deteriorates
Solution Approach 1:
Validation procedures are performed preliminarily before allowing data communication or lock operation. The controller validates the key's identification data and authorization credentials before establishing communication channels or executing lock/unlock commands. This preliminary validation ensures security without significantly impacting user experience, as the verification process occurs automatically in the background.
Solution Approach 2:
The controller acts as an intermediary between the key and the lock mechanism, mediating all data communication through validated channels. It verifies authorization credentials and manages communication protocols, providing a secure intermediate layer that protects both the simplicity of operation and the security of the system.
3Reliability
If unencrypted data communication is used, then the ease of manufacture is improved, but the security of data transmission deteriorates
Solution Approach 1:
The system dynamically changes communication parameters including encryption status based on the communication channel being used. Different data ports can operate with different encryption levels - some channels use encrypted communication while others use unencrypted communication, allowing the system to balance security requirements with manufacturing simplicity for each specific communication path.
