Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If user emotion data is stored and processed to execute appropriate actions, then the appropriateness of executed actions is improved, but the device complexity increases due to multiple units (storage, estimation, prediction, control)

Engineering Contradiction:
Improveappropriateness of executed actionsVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system is divided into distinct functional units: storage unit for emotion data, estimation unit for current emotion analysis, prediction unit for future emotion forecasting, and control unit for action execution. This segmentation allows each unit to specialize in specific tasks, improving overall reliability while managing complexity through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The prediction unit forecasts future emotional states in advance before actual interactions occur. By preparing prediction data beforehand, the control unit can select appropriate actions proactively, improving the timeliness and appropriateness of responses without requiring complex real-time processing during critical moments.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If user emotion data is collected and processed, then the personalization of user experience is improved, but the security and privacy protection requirements increase

Engineering Contradiction:
Improvepersonalization of user experienceVSAvoidsecurity and privacy risks
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The storage unit maintains separate emotion data records for different users, with each user's data processed independently. This localized data handling approach enables personalized action selection for each user while minimizing cross-user privacy risks, as each user's emotional profile is kept distinct and processed individually.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system implements predetermined privacy protection measures and security protocols before data processing occurs. By establishing security frameworks in advance, the system protects user information from potential breaches while still enabling personalized emotion-based interactions.

Inventive Principle:
Principle #9Preliminary anti-action

3Measurement precision

If continuous emotion monitoring is performed to predict future emotional states, then the accuracy of action selection is improved, but the energy consumption increases

Engineering Contradiction:
Improveaccuracy of emotion predictionVSAvoidenergy consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The estimation unit performs emotion analysis at periodic intervals rather than continuously, balancing monitoring accuracy with energy conservation. This periodic sampling approach captures sufficient emotional state changes for accurate prediction while significantly reducing computational load and power consumption compared to continuous monitoring.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system monitors only the most relevant emotional indicators necessary for accurate prediction, rather than analyzing all possible emotional parameters. This partial monitoring approach maintains sufficient prediction accuracy while minimizing the energy required for data collection and processing.

Inventive Principle:
Principle #16Partial or excessive action
