Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If artificial participation is used to test biometric recognition devices, then the testing process is simple to implement, but the performance determining accuracy is poor due to variations in biometric characteristics and environmental conditions

Engineering Contradiction:
Improvetesting process simplicityVSAvoidperformance determining accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent uses simulated components that replicate human biometric characteristics (fingerprints, facial features, iris patterns) to replace actual human participants in the testing process. These simulated components are created based on real biometric data and can be repeatedly used under controlled conditions, eliminating the variability inherent in human participants while maintaining the authenticity of biometric recognition testing.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent systematically varies test parameters including environmental conditions (lighting, temperature, humidity), biometric characteristic variations (pattern clarity, moisture content, pressure), and device operating parameters. By controlling and adjusting these parameters, the system achieves comprehensive testing under multiple scenarios while maintaining consistent and repeatable conditions, thereby improving measurement accuracy.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If artificial participation is used to test biometric recognition devices, then the testing method is easy to implement, but the performance determining efficiency is low

Engineering Contradiction:
Improvetesting method simplicityVSAvoidperformance determining efficiency
Core Design Contradiction:

Solution Approach 1:

Simulated components can be rapidly deployed and reused without requiring human participants, eliminating setup time, environmental adaptation time, and subject availability constraints. The simulated components remain available indefinitely and can be tested repeatedly without fatigue or variation, dramatically increasing testing throughput and efficiency.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The testing system enables continuous operation without interruption by using simulated components that do not require rest, adaptation, or repositioning between tests. The mechanical arm can continuously present simulated biometric characteristics to the recognition device, maintaining constant testing activity and maximizing productivity.

Inventive Principle:
Principle #20Continuity of useful action

3Measurement precision

If simulated components are used with mechanical arm control, then the performance determining accuracy is improved through standardized test parameters, but the device complexity increases

Engineering Contradiction:
Improveperformance determining accuracyVSAvoidtesting system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The mechanical arm system serves multiple functions: it positions simulated components, controls pressing force and angle, adjusts positioning precision, and coordinates with environmental control systems. This multi-functional approach consolidates what would otherwise require separate devices into a single integrated system, managing complexity while achieving precise standardized testing.

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

Solution Approach 2:

The mechanical arm acts as an intermediary between the control system and the simulated biometric components, translating control signals into precise physical actions (positioning, pressing, orienting). This intermediary layer enables standardized testing parameters to be implemented without requiring direct manual intervention, improving accuracy while keeping the system manageable through automated control.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Productivity

If simulated components are used with mechanical arm control, then the performance determining efficiency is improved, but the device complexity increases

Engineering Contradiction:
Improveperformance determining efficiencyVSAvoidtesting system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The mechanical arm enables continuous automated testing by rapidly positioning and presenting simulated biometric components without interruption. The system maintains constant testing activity through automated sequences, eliminating idle time between tests and maximizing productivity despite the added complexity of automated control systems.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The testing system performs self-positioning, self-adjustment, and self-testing through automated mechanical arm control and programmed sequences. The system requires minimal human intervention after initial setup, operating autonomously to present simulated components, control test parameters, and collect results, thereby improving efficiency while the complexity is managed through automation rather than manual coordination.

Inventive Principle:
Principle #25Self-service
