Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single identity authentication mode is set in the smart key device, then the device structure remains simple, but the device cannot meet different authentication requirements in different application scenarios
Solution Approach 1:
The patent segments the authentication functionality by dividing authentication modes into different key areas (first key area, second key area, third key area), each supporting different authentication methods (password, fingerprint, facial recognition, etc.). This allows the device to offer multiple authentication modes without creating a monolithic complex system, as each key area can be independently configured and managed.
Solution Approach 2:
The patent implements dynamic authentication mode selection where the system automatically determines which authentication mode to use based on the current application scenario and key area. The authentication mode is not fixed but adapts dynamically according to the operational context, allowing the device to switch between simple and complex authentication approaches as needed.
2Adaptability or versatility
If multiple biometric authentication modes are provided, then personalized authentication is achieved, but the device complexity increases
Solution Approach 1:
The patent applies local quality by assigning different biometric authentication capabilities to different key areas based on their specific requirements. For example, the first key area may support fingerprint authentication while the second key area supports facial recognition, allowing each key area to have the specific authentication quality it needs without requiring all key areas to support all authentication modes.
Solution Approach 2:
The patent creates a universal authentication framework where a single smart key device can perform multiple authentication functions (password, fingerprint, iris, hand shape, facial shape, retina scanning) across different key areas. This multi-functionality is achieved through a unified architecture that can selectively activate different authentication modes based on the application scenario.

AI summary
An intelligent key device and a verification method therefor. The verification method comprises: determining the type of an instruction by means of an intelligent key device; determining a key area according to the type of the instruction; acquiring a biometric verification identifier corresponding to the key area; determining, according to the biometric verification identifier, a biometric verification mode corresponding to the key area; and executing a corresponding operation according to the biometric verification mode. According to the present invention, a user can realize multiple verification modes of biometric features according to a key area in the process of performing verification using the intelligent key device, such that different verification requirements of the user for the key used in different application scenarios are met.
