Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If LiDAR systems use traditional static three-dimensional model generation, then the model creation process is simple, but the model accuracy and real-time representation capability deteriorate
Solution Approach 1:
The patent implements dynamic updating of three-dimensional models by continuously receiving new light signals and automatically regenerating model data in real-time, transforming the static model generation process into a dynamic one that adapts to changing environments and improves measurement precision
Solution Approach 2:
The system employs feedback mechanisms where decoded information from received light signals is used to automatically determine whether model updates are needed and to guide the regeneration process, creating a closed-loop system that enhances accuracy without requiring complex manual intervention
2Adaptability or versatility
If LiDAR systems enable real-time model updates based on decoded information, then the interactivity and user engagement improve, but the processing complexity and time consumption increase
Solution Approach 1:
The patent performs preliminary actions by pre-processing and decoding light signals as they are received, preparing data in advance for potential model updates. This reduces the processing time required when updates are triggered by user interactions, as the data preparation work has already been completed
Solution Approach 2:
The system implements selective model updating based on decoded information, performing updates only when necessary rather than continuously. This partial action approach maintains interactivity and adaptability while reducing overall processing time and resource consumption
3Loss of information
If LiDAR systems decode multiple light signals with different directions of arrival, then the information richness and model detail improve, but the decoding complexity and computational load increase
Solution Approach 1:
The patent segments the decoding process by classifying decoded information into different groups based on direction of arrival. This segmentation allows the system to handle multiple light signals systematically, organizing information by spatial origin and reducing the complexity of processing diverse data streams
Solution Approach 2:
The decoding means is designed with multi-functionality to handle various types of light signals from different directions using a unified decoding framework. This universal approach enables the system to process diverse information sources without requiring separate decoding mechanisms for each signal type
