Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If camera-based systems are used for augmented reality placement, then the system is easy to operate, but measurement precision and re-localization accuracy deteriorate
Solution Approach 1:
The patent combines multiple positioning technologies (visual-inertial odometry, radio wave positioning, acoustic positioning) into a unified system. This merging of different measurement methods enables the system to achieve high precision placement and re-localization while maintaining ease of operation through automated multi-sensor fusion.
Solution Approach 2:
The patent introduces a server as an intermediary that receives data from multiple locationing devices, processes the information, and determines decided values for physical objects. This intermediary coordinate system acts as a mediator between various positioning methods and the final augmented reality placement, ensuring high accuracy without requiring complex user calibration.
2Measurement precision
If complex calibrated equipment is used for accurate placement, then measurement precision improves, but device complexity increases
Solution Approach 1:
The system performs self-calibration and self-positioning through automated sensor fusion. The multiple locationing devices automatically determine their positions and orientations relative to each other and to physical objects without requiring manual calibration by users. This self-service approach maintains high precision while minimizing the complexity of user operations.
Solution Approach 2:
The patent creates a universal coordinate system that can be used across multiple devices and applications. The server maintains a digital map and digital library that serve multiple functions: storing spatial information, enabling re-localization, and supporting various augmented reality applications. This multi-functionality reduces the need for separate calibration equipment for different use cases.
3Measurement precision
If occlusion handling is improved through precise metrics, then measurement precision improves, but the difficulty of detecting and measuring increases
Solution Approach 1:
The patent moves the complexity of occlusion detection from the 2D camera view to a 3D spatial coordinate system. By establishing precise three-dimensional positions and orientations of physical objects through multi-sensor fusion, the system can accurately determine occlusion relationships without the difficulty of analyzing 2D image data alone. The added spatial dimension simplifies occlusion detection while improving measurement precision.
