Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fingerprint sensor is integrated into existing mechanical lock, then access control functionality is improved, but installation complexity increases
Solution Approach 1:
The patent replaces mechanical wiring and integration with wireless communication technology. The fingerprint sensor communicates with the lock mechanism via Bluetooth Low Energy (BLE), eliminating the need for complex physical wiring, electrical connections, and mechanical integration with existing lock systems. This substitution of mechanical systems with wireless electronic communication directly resolves the installation complexity issue while maintaining access control functionality.
Solution Approach 2:
The patent introduces a wireless communication intermediary (Bluetooth Low Energy module) between the fingerprint sensor and the lock mechanism. This intermediary enables data transmission without physical connections, simplifying the integration process. The wireless intermediary handles the communication protocol and data exchange, allowing the fingerprint sensor to control the lock without direct mechanical or electrical integration.
2Ease of operation
If wireless communication is used between handle and lock, then ease of installation is improved, but security risks may increase
Solution Approach 1:
The patent changes the communication parameter from wired to wireless (Bluetooth Low Energy), which improves ease of installation. However, to maintain security, the system implements encrypted communication channels and secure authentication protocols, effectively managing the security parameter despite the wireless medium.
Solution Approach 2:
The patent implements a feedback mechanism where the lock and handle verify each other's identity and authentication status before allowing access. The system continuously monitors the wireless communication for anomalies and validates the fingerprint data against stored templates, providing feedback loops that enhance security despite using wireless communication.
Data Source
AI summary
It is provided a lock device for controlling access to a physical space. The lock device comprises: an electronically controllable lock; and a handle comprising a fingerprint sensor for capturing a fingerprint of a finger presented to the fingerprint sensor and obtaining fingerprint data based on a captured fingerprint, wherein the handle is configured to communicate wirelessly with the electronically controllable lock to selectively control unlocking of the electronically controllable lock based on the fingerprint data. The handle is configured to identify a user from the captured fingerprint, wherein an identifier of the identified user is communicated wirelessly from the handle to the electronically controllable lock to enable the electronically controllable lock to evaluate whether to perform an unlocking action.
