Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If AR systems use basic display modules without advanced sensing capabilities, then device complexity is reduced, but the ability to precisely detect and respond to hand motion is limited
Solution Approach 1:
The patent combines multiple sensing functions (image sensing, depth sensing, motion sensing) into an integrated sensing module that works cooperatively with the display module. This merging allows the system to achieve precise hand motion detection through multiple sensors working together rather than requiring a single complex sensor, thus improving measurement precision while managing device complexity through functional integration.
Solution Approach 2:
The sensing module is designed to perform multiple functions: detecting hand position, tracking motion trajectories, recognizing gestures, and providing depth information. This multi-functionality allows a single sensing module to handle various detection tasks, improving measurement precision across different operational scenarios without proportionally increasing device complexity.
2Adaptability or versatility
If AR systems implement real-time hand motion detection and content modulation, then adaptability to user interaction is improved, but processing time and system complexity increase
Solution Approach 1:
The system performs preliminary actions by continuously pre-processing sensor data and maintaining ready-state detection algorithms. The sensing module continuously captures hand motion data and the control module pre-calculates potential content modifications, so when actual interaction occurs, the system can respond quickly without significant processing delays, thus reducing loss of time while maintaining high adaptability.
Solution Approach 2:
The system implements real-time feedback loops where hand motion detection results immediately influence AR content modulation, which is then displayed and continues to respond to subsequent motions. This continuous feedback mechanism enables high adaptability to user interaction while optimizing processing time through iterative refinement rather than complete re-processing.
3Measurement precision
If AR systems use multiple sensors for precise hand detection, then detection accuracy is improved, but the number of components and device complexity increase
Solution Approach 1:
The patent merges multiple sensing functions into an integrated sensing module that coordinates image sensors, depth sensors, and motion sensors. This consolidation allows the system to achieve high hand location detection accuracy through multiple sensors working together while managing device complexity through unified module architecture and coordinated data processing.
Solution Approach 2:
The control module serves as an intermediary that receives data from multiple sensors, processes and integrates the information, and coordinates the sensing module's operations. This intermediary function allows multiple sensors to work together efficiently, improving detection accuracy while managing the complexity of having multiple components through centralized coordination.
