Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If automatic vision correction is implemented using sensors and real-time monitoring, then user experience is improved and operations are reduced, but device complexity increases

Engineering Contradiction:

Improvevision correction operationsVSAvoidsensor monitoring system

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system automatically detects user entry into the virtual reality environment using sensors and autonomously provides initial visual position without requiring manual user operations. The system monitors user state and scene changes, automatically adjusting visual position when the user is in a stable state, thereby eliminating the need for tedious menu operations or device restarts.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system continuously monitors user state through sensors (distance/light sensors, gyroscopes, accelerometers) and provides real-time feedback by detecting when the user enters or exits the virtual reality environment, when the user is in a stable or unstable state, and when scene discontinuous switching occurs. This feedback loop enables automatic vision correction by adjusting visual position based on monitored conditions.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If manual vision correction interface is provided with multiple input methods, then adaptability is improved, but device complexity increases

Engineering Contradiction:

Improvemanual correction interfaceVSAvoidinterface system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The manual vision correction interface supports multiple input methods including joystick, hand gesture recognition, voice recognition, and eye tracking. Each input method can independently control visual position adjustment, allowing users to choose their preferred interaction mode. This multi-functional interface design enhances adaptability to different user preferences and accessibility needs.
