Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional access control methods (fingerprint, face recognition) are used, then basic security is provided, but security robustness is insufficient for high-security scenarios

Engineering Contradiction:

Improvesecurity robustnessVSAvoidverification method complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the verification process into multiple independent components: initial face recognition for user identification, followed by eyelash movement analysis as a separate verification layer. This segmentation allows the system to maintain basic security while adding robustness through layered verification without requiring complete system redesign.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary face recognition to identify the user before proceeding to eyelash movement verification. This preliminary action establishes a baseline identity check, and only after successful initial verification does the system activate the more complex eyelash movement analysis, thereby managing complexity through staged verification.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If additional verification methods are added to enhance security, then security robustness improves, but ease of operation deteriorates

Engineering Contradiction:

Improvesecurity robustnessVSAvoidaccess control convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The eyelash movement verification operates autonomously after initial face recognition - the system automatically captures, analyzes, and processes eyelash movement characteristics without requiring user intervention. The user simply needs to maintain their facial orientation, and the system handles the complex verification process itself, maintaining ease of operation while enhancing security.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The verification process continues seamlessly from face recognition to eyelash movement analysis without interrupting the user flow. The system maintains continuous monitoring and processing, allowing the user to complete authentication naturally through normal facial movements rather than requiring deliberate additional actions.

Inventive Principle:

Principle #20Continuity of useful action

3Reliability

If eyelash movement verification is implemented, then security robustness improves, but device complexity increases

Engineering Contradiction:

Improveverification accuracyVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The existing face recognition camera system is extended to perform multiple functions: initial face identification and subsequent eyelash movement verification. By making the imaging system multi-functional, the patent avoids adding separate dedicated hardware for eyelash verification, thereby improving verification accuracy while limiting the increase in overall system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces image processing algorithms as intermediaries that bridge the existing camera system and the new eyelash verification functionality. These software-based intermediaries process the captured images to extract eyelash movement characteristics, allowing the system to enhance verification accuracy without requiring complex new hardware components.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Reliability

If conventional authentication methods are used, then ease of operation is maintained, but security robustness deteriorates in emergency scenarios

Engineering Contradiction:

Improveemergency response capabilityVSAvoidauthentication simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system dynamically adapts its verification requirements based on the authentication context. For emergency scenarios, the eyelash movement verification can be configured with relaxed parameters or bypassed entirely after successful face recognition, allowing rapid response while maintaining enhanced security for normal operations. This dynamic adjustment resolves the contradiction between emergency responsiveness and security robustness.

Inventive Principle:

Principle #15Dynamics

AI summary

Apparatus having one or more processors configured to receive images of a face of a user and to use the images to identify whether a user is an approved user, and, if the user has been identified as an approved user, to determine an eyelash movement characteristic of the user from the images and to perform an operation according to the determined eyelash movement characteristic of the user.
