Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a virtual or augmented reality headset is used to display virtual components corresponding to physical hardware components, then the user experience is improved and the need for full-scale mock-ups is reduced, but the accuracy in matching the positioning of physical and digital models deteriorates

Engineering Contradiction:
Improveuser experienceVSAvoidpositioning accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The system employs object detection sensors to continuously monitor the positions of physical hardware components and provides feedback to the control system. This feedback loop enables real-time adjustment and synchronization of virtual component positions with their physical counterparts, resolving the positioning accuracy issue while maintaining the improved user experience from using VR/AR technology

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces traditional mechanical measurement and alignment systems with electronic sensing and computational methods. Object detection sensors and sensor fusion algorithms substitute for manual positioning and mechanical alignment, enabling automatic synchronization between physical and virtual models while improving both accuracy and user experience

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

2Measurement precision

If sensor data fusion processing is implemented to determine positions of objects relative to the headset, then the positioning accuracy is improved, but the device complexity increases

Engineering Contradiction:
Improvepositioning accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The control system performs multiple functions through a single integrated platform: it manages actuator control, processes sensor data from multiple sources, performs sensor fusion calculations, and coordinates virtual component positioning. This multi-functionality reduces the need for separate dedicated systems for each function, thereby limiting the increase in device complexity while achieving improved positioning accuracy

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