Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional sensors (GPS, compass, accelerometer) are used for alignment in AR devices, then the device can provide basic location and orientation information, but the alignment accuracy deteriorates due to signal loss and insufficient precision
Solution Approach 1:
The patent introduces lighting system sensors as an intermediary component that mediates between the AR device and the environment. These external sensors capture environmental features and transmit data to the AR device, serving as a reliable intermediary when conventional onboard sensors fail or provide insufficient accuracy.
Solution Approach 2:
The patent combines data from multiple sources including conventional sensors (GPS, compass, accelerometer) with environmental sensor data from the lighting system. By merging these complementary data sources, the system achieves both high reliability (through redundancy) and high measurement precision (through fused environmental features).
2Measurement precision
If image processing is used to complement or replace conventional sensors for precise localization, then alignment precision improves through environmental feature matching, but the device complexity increases due to additional processing requirements
Solution Approach 1:
The patent extracts the complex image processing and environmental feature analysis functions from the AR device itself and relocates them to external lighting system sensors. This extraction reduces the processing burden on the AR device while maintaining high localization precision through environmental feature matching.
Solution Approach 2:
The lighting system acts as an intermediary that performs environmental feature extraction and processing. Instead of the AR device directly analyzing environmental features (which would increase its complexity), the lighting system sensors capture and process these features, then provide the processed data to the AR device.
