Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If visual inspection or single laser measuring device is used, then device complexity is low, but measurement precision is insufficient
Solution Approach 1:
The system divides the measurement task into multiple segments by deploying multiple LiDAR sensors at different positions and orientations. Each sensor captures a portion of the raw material volume, and the volume data integration calculator combines these segmented measurements into a complete three-dimensional point cloud, achieving high measurement precision without requiring a single overly complex device
Solution Approach 2:
The volume data integration calculator merges data from multiple LiDAR sensors by integrating their respective three-dimensional point clouds into a unified coordinate system. This combining approach consolidates multiple simple sensor measurements into a single comprehensive volume measurement, resolving the contradiction between using multiple sensors and system complexity
2Productivity
If traditional measurement methods are used, then device complexity is low, but real-time monitoring capability is lacking
Solution Approach 1:
The LiDAR sensors continuously scan the raw materials in the storage space, maintaining an ongoing measurement process rather than periodic or manual inspections. The volume data integration calculator continuously processes the incoming data streams, providing uninterrupted real-time volume information for inventory management
Solution Approach 2:
The system replaces traditional mechanical measurement devices and manual visual inspection with optical LiDAR technology. This substitution enables non-contact, automated, continuous measurement capabilities, achieving real-time monitoring while the electronic processing system manages the complexity rather than mechanical components
3Measurement precision
If multiple LiDAR sensors are deployed, then measurement precision and real-time capability improve, but device complexity increases
Solution Approach 1:
The volume data integration calculator serves multiple functions simultaneously: it receives data from multiple LiDAR sensors, synchronizes their coordinate systems, integrates their three-dimensional point clouds, filters noise, calculates volumes, and provides real-time monitoring outputs. This multi-functionality consolidates what would otherwise be separate complex components into a single universal processing unit
Solution Approach 2:
The volume data integration calculator acts as an intermediary between the multiple LiDAR sensors and the final volume measurement output. It mediates the coordination and integration of data from various sensors, managing the complexity of multiple devices through a central processing interface that standardizes and harmonizes their combined measurements
