Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple bio authentication methods are performed simultaneously, then authentication security is improved, but authentication time increases

Engineering Contradiction:

Improveauthentication securityVSAvoidauthentication time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system dynamically adjusts the authentication process by detecting which bio authentication method the user intends to use and temporarily suspending other authentication methods during the active authentication. This dynamic suspension and resumption mechanism allows the system to maintain security by having multiple authentication methods available while reducing authentication time by actively using only one method at a time.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If multiple bio authentication methods are maintained active, then authentication versatility is improved, but CPU resource consumption increases

Engineering Contradiction:

Improveauthentication versatilityVSAvoidCPU resource consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The system dynamically manages CPU resources by adjusting the occupancy rate of authentication processes based on user behavior. When a user selects a specific authentication method, the system increases CPU allocation to that method while suspending others, thereby maintaining versatility while optimizing resource consumption.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the operational parameters of authentication processes by temporarily suspending and resuming them based on detected user input. This parameter change allows the system to maintain multiple authentication methods available (versatility) while actively using only one at a time (resource efficiency).

Inventive Principle:

AI summary

An electronic device is provided. The electronic device includes a fingerprint sensor, a camera, and a processor operatively coupled to the fingerprint sensor and the camera. The processor may be configured to determine whether a plurality of biometric authentications are being performed when an input for performing user authentication is detected through the fingerprint sensor, stop user authentication using the camera if it is determined that the plurality of biometric authentications are being performed, and perform user authentication if a fingerprint image acquired through the fingerprint sensor matches a previously registered fingerprint image.
