Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional multi-factor authentication methods are used to verify user identity, then security and reliability of access to prescription information is improved, but user convenience deteriorates due to invasiveness and time consumption

Engineering Contradiction:

Improveauthentication reliabilityVSAvoiduser convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces conventional mechanical authentication methods (keyboards, buttons, physical tokens) with voice-based acoustic authentication. The system captures voice prints through microphones, processes them to extract unique acoustic features, and verifies user identity without requiring physical interaction with device interfaces, thereby improving convenience while maintaining security

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system performs self-service authentication by automatically capturing and processing voice prints without requiring user intervention beyond speaking. The authentication process is initiated and completed automatically based on voice recognition, eliminating the need for users to manually enter credentials or interact with complex authentication interfaces

Inventive Principle:

Principle #25Self-service

2Reliability

If conventional authentication methods are used, then security assurance is improved, but time consumption increases making the process slower

Engineering Contradiction:

Improveidentity verification assuranceVSAvoidauthentication time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary voice print capture and processing during the authentication process itself, eliminating the need for separate credential entry steps. Voice prints are captured and verified in a single continuous action, reducing authentication time while maintaining security through multi-factor voice analysis

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The authentication process maintains continuous useful action by processing voice prints in real-time without interruption. The system continuously analyzes acoustic features during the voice capture process, providing immediate verification rather than requiring discrete steps with delays between them

Inventive Principle:

Principle #20Continuity of useful action

3Ease of operation

If voice and audio interactions are implemented for authentication, then user convenience and speed of access are improved, but system complexity increases

Engineering Contradiction:

Improveaccess convenienceVSAvoidauthentication system complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system uses universal acoustic principles that work across different devices and environments. Voice print authentication leverages inherent human vocal characteristics that remain consistent across various electronic devices, eliminating the need for device-specific authentication mechanisms and reducing overall system complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces voice prints as an intermediary between the user and the authentication system. Instead of directly processing complex biometric data or requiring multiple authentication factors, the system uses voice prints as a mediating representation that simplifies the authentication process while maintaining security

Inventive Principle:

Principle #24Intermediary (Mediator)

4Speed

If audio tone detection is used for authentication, then authentication speed is improved, but measurement precision requirements increase

Engineering Contradiction:

Improveauthentication speedVSAvoidaudio tone detection precision

Core Design Contradiction:

SpeedVSMeasurement precision

Solution Approach 1:

The system uses partial voice print analysis by focusing on specific acoustic features (pitch, tone, rhythm) rather than requiring complete spectral analysis. This selective approach to voice feature extraction maintains authentication speed while reducing the precision requirements compared to full voice biometric analysis

Inventive Principle:

Principle #16Partial or excessive action
