Solution Overview

Problem

Existing biometric authentication technologies, such as iris authentication, often fail due to various environmental and user-related factors, leading to user dissatisfaction and potential security risks when users switch to less secure methods like ID and password authentication.

Innovation Solution

An electronic device and method that determines the cause of failed biometric authentication and controls the environment or user actions to optimize iris acquisition, using sensors and external devices to guide users in creating a suitable environment for iris authentication, thereby improving authentication success rates.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If biometric authentication is performed using existing technology, then authentication can be conducted, but authentication fails due to various environmental and user-related factors

Engineering Contradiction:

Improveauthentication success rateVSAvoidenvironmental factors affecting iris acquisition

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary assessment of environmental conditions (lighting, temperature, humidity) before attempting biometric authentication. By evaluating these factors in advance, the system can determine whether conditions are suitable for successful iris acquisition, and can guide users to adjust their environment or posture before authentication is attempted, thereby preventing authentication failure due to unfavorable conditions.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system provides real-time feedback to users about the current environmental conditions and their impact on authentication. When environmental factors are detected to be suboptimal, the system notifies users and guides them on how to improve conditions (such as adjusting lighting or posture). This feedback loop enables users to make appropriate adjustments, thereby improving authentication success rates.

Inventive Principle:

Principle #23Feedback

2Loss of information

If users are notified of authentication failure causes, then users can understand the problem, but users must figure out removal methods themselves which is complicated

Engineering Contradiction:

Improveinformation about failure causeVSAvoiduser effort to remove failure cause

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The system automatically performs multiple functions that would otherwise require user intervention. It not only notifies users of the failure cause but also automatically adjusts environmental conditions (such as lighting control, temperature regulation, or posture guidance through display/voice) to resolve the issue. This self-service approach eliminates the need for users to independently figure out complex removal methods.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system acts as an intermediary between the authentication system and the user environment. Instead of merely informing users of problems and hoping they can solve them, the system mediates by automatically implementing corrective actions (such as controlling external devices for lighting adjustment or providing step-by-step guidance through display and voice output) to bridge the gap between problem identification and resolution.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If environmental control is implemented to improve iris acquisition, then authentication reliability improves, but device complexity increases

Engineering Contradiction:

Improvebiometric authentication reliabilityVSAvoidsystem complexity for environment control

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system integrates multiple functions into a single unified platform. It combines environmental sensing (lighting, temperature, humidity detection), environmental control (controlling external devices for lighting and temperature adjustment), user guidance (display and voice output), and authentication processing. By making the system universal and multi-functional, the complexity is centralized and managed efficiently, rather than requiring separate independent systems for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges environmental monitoring, environmental control, user notification, and authentication functions into an integrated system. By combining these previously separate functions into a unified system that can automatically assess environmental conditions, control environmental factors, guide users, and perform authentication, the overall system complexity is reduced through functional integration and coordinated operation.

Inventive Principle:

Principle #5Merging (Combining)
