Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fingerprint recognition module is added to provide fingerprint unlocking function, then user authentication security is improved, but device complexity increases
Solution Approach 1:
The patent combines the fingerprint recognition module with the existing camera module, allowing the fingerprint sensor to be integrated into the camera assembly. This merging approach enables dual functionality (photography and biometric authentication) from a single integrated component, improving security while minimizing the increase in device complexity.
Solution Approach 2:
The camera module is designed to serve multiple purposes: it functions as both a photography device and a fingerprint recognition sensor. By making the camera module universal, the system achieves fingerprint unlocking capability without adding a separate dedicated fingerprint sensor, thus improving authentication security while avoiding significant complexity increases.
2Ease of operation
If multiple unlocking methods (password, pattern, PIN) are provided, then user convenience is improved, but device complexity increases
Solution Approach 1:
The unlocking system is designed with multi-functionality, supporting multiple authentication methods (fingerprint, password, pattern, PIN) through a unified interface. This universal approach allows users to choose their preferred method while the system manages all options through a single centralized unlocking mechanism, improving convenience without proportionally increasing complexity.
Solution Approach 2:
The system automatically detects and switches between different unlocking methods based on user input. When a fingerprint is detected, the system automatically activates fingerprint recognition; otherwise, it presents other authentication options. This self-service capability reduces the burden on users to manually select unlocking methods while keeping the underlying complexity managed through automated logic.
3Adaptability or versatility
If fingerprint recognition module is integrated into camera module, then device integration level is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent integrates the fingerprint recognition module into the camera module assembly, combining two functional components into a single integrated unit. This merging improves device versatility and space utilization, though it requires coordinated manufacturing processes to ensure both the camera and fingerprint sensor meet their respective precision requirements within the integrated structure.

AI summary
An electronic device unlocking method and a related device are provided, applied to a first electronic device. The method includes: receiving operation information sent by a second electronic device; sending first information to the second electronic device when determining, based on the operation information, to unlock a to-be-unlocked object of the first electronic device, where the first information is used by the second electronic device to collect authentication information required for unlocking the to-be-unlocked object; obtaining authentication information from the second electronic device to perform authentication of a user; and unlocking the to-be-unlocked object of the first electronic device when the authentication of the user succeeds. According to the method, the first electronic device can be unlocked on the second electronic device, thereby ensuring unlocking security and convenience.
