Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If calibration is performed based on an object in the overlapping range of multiple spatial recognition devices, then calibration among devices can be achieved, but it is difficult to adjust the position of the calibration target and the process requires excessive time
Solution Approach 1:
The spatial recognition devices automatically detect and identify calibration targets within their detection ranges without requiring manual positioning or adjustment by operators. The control device autonomously determines which devices can detect the target and performs calibration computations automatically, eliminating the time-consuming manual intervention previously required.
Solution Approach 2:
The control device receives detection results from multiple spatial recognition devices and uses this feedback information to determine the optimal calibration target position. Based on the detected object positions and device detection ranges, the system automatically adjusts and optimizes the calibration process, reducing the time required while maintaining accuracy.
2Adaptability or versatility
If multiple spatial recognition devices are provided to monitor the surrounding of the work machine, then comprehensive spatial recognition capability is improved, but the calibration process becomes more complex and time-consuming
Solution Approach 1:
The control device performs multiple functions: it manages detection ranges of multiple spatial recognition devices, identifies calibration targets, determines optimal positions, and executes calibration computations for all devices. This centralized multi-functional approach simplifies the overall calibration process despite the presence of multiple devices.
Solution Approach 2:
The patent combines the calibration operations of multiple spatial recognition devices into a unified process managed by a single control device. By merging the calibration workflows and using a common calibration target detectable by multiple devices, the system reduces calibration complexity while maintaining comprehensive spatial recognition capability.
