Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If handheld controllers are used for VR/AR interactions, then user interaction capability is improved, but processing power and bandwidth are constrained
Solution Approach 1:
The system divides the computing device into multiple wearable units distributed across the user's body (head-mounted display, hand-mounted controllers, wrist-mounted devices). This segmentation allows processing tasks to be distributed across multiple independent units, reducing the processing burden on any single device while maintaining comprehensive interaction capabilities.
Solution Approach 2:
The patent transitions from traditional 2D screen-based interaction to 3D spatial interaction by mounting sensors and haptic motors on the user's hands and fingers. This adds a dimensional aspect to interaction, enabling natural hand gestures and finger movements to control virtual objects, thereby improving interaction capability without requiring increased processing power for complex UI rendering.
2Weight of moving object
If mobile computing devices are used, then portability is improved, but processing power and bandwidth are further constrained
Solution Approach 1:
The computing system is segmented into multiple lightweight wearable components rather than relying on a single mobile device. Each component (HMD, hand controllers, wrist device) has minimal processing requirements, maintaining portability while collectively providing sufficient computational capability through distributed processing and cloud connectivity.
Solution Approach 2:
The wearable computing components are designed to serve multiple functions: sensing hand/finger position, providing haptic feedback, displaying visual information, and communicating wirelessly. This multi-functionality reduces the need for separate specialized devices, maintaining portability while achieving comprehensive interaction capabilities.
3Ease of operation
If sensors and haptic motors are added to enhance interaction, then interaction capability is improved, but device complexity increases
Solution Approach 1:
Sensors and haptic motors are segmented and distributed across multiple wearable components rather than concentrated in one device. Each component contains a subset of sensors and actuators appropriate to its location, reducing the complexity of individual components while collectively providing comprehensive sensing and feedback capabilities.
Solution Approach 2:
The patent combines multiple functions (sensing, haptic feedback, wireless communication, power management) into integrated wearable components. By merging these functions into unified modules worn on different parts of the body, the system reduces overall complexity compared to using multiple separate devices, while enhancing interaction capability through coordinated operation.
