Innovation Solution

A mobile device equipped with a pupil information collecting module, comprising a pupil scanner, driver, microprocessor, and master control module, uses pupil characteristic information like distance, luminance, and capillary lines for identity verification, ensuring secure access to system programs and files.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If password encryption is used for file protection, then the device can provide basic security, but the security level remains relatively low due to easy compromise

Engineering Contradiction:
Improvesecurity levelVSAvoidauthentication mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical/password-based authentication systems with a biological authentication system using pupil characteristic information. The pupil scanner captures and analyzes unique pupil features (capillary patterns, curvature, luminance) to authenticate users, substituting the mechanical key-entry process with an optical biometric verification system that provides higher security without significantly increasing user-facing complexity

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The invention changes the authentication parameter from user-provided passwords to physiological pupil characteristics. By measuring and comparing multiple pupil parameters (capillary line patterns, curvature radius, luminance values) rather than relying on user-chosen passwords, the system achieves higher reliability while maintaining ease of operation through automatic capture

Inventive Principle:
Principle #35Parameter changes

2Reliability

If fingerprint recognition is used for security protection, then identity verification is improved, but security remains risky because fingerprints can be stolen through daily interactions

Engineering Contradiction:
Improveidentity verification securityVSAvoidrisk of biometric theft
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent focuses on a specific local feature of the eye (the pupil region) rather than using entire fingerprint patterns. By targeting the unique capillary patterns within the pupil area specifically, the system creates a localized biometric identifier that is harder to steal or replicate compared to broader biometric data, improving security against biometric theft

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system creates a digital model or template of the user's pupil characteristics during registration, storing only the essential feature parameters (capillary patterns, curvature, luminance) rather than complete biometric images. This selective copying and storage of critical features reduces the risk associated with storing or transmitting complete biometric data

Inventive Principle:
Principle #26Copying

3Measurement precision

If multiple pupil parameters are measured for authentication, then measurement precision and security are improved, but the complexity of the measurement system increases

Engineering Contradiction:
Improvepupil characteristic measurement accuracyVSAvoidpupil scanner system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple measurement functions (distance measurement, luminance detection, curvature measurement) into a single integrated pupil scanner device. By merging these measurement capabilities into one unified instrument rather than using separate devices, the system achieves high measurement precision while controlling overall system complexity through functional integration

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The pupil scanner is designed as a multi-functional device that can simultaneously or sequentially perform multiple measurement tasks (ultrasonic distance measurement, photosensitive luminance detection, geometric curvature measurement). This universal design allows the single device to gather comprehensive pupil characteristics needed for accurate authentication without requiring multiple specialized instruments

Inventive Principle:
Principle #6Universality (Multi-functionality)
