Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If human observation or simple distance measurement devices are used, then the method is simple and easy to operate, but the measurement precision and detail capture of terrain features (slope, undulations, unevenness, turf changes) are insufficient
Solution Approach 1:
The patent replaces simple mechanical distance measurement devices with a spatial multi-dimensional scanning device that uses structured light projection and visible light imaging to capture terrain data. This substitution enables precise measurement of slope, undulations, unevenness, and turf changes by analyzing the deformation of projected light patterns and multi-angle imaging, thereby achieving high measurement precision while maintaining operational simplicity through automated processing.
Solution Approach 2:
The patent transitions from one-dimensional distance measurement to multi-dimensional spatial scanning by projecting structured light patterns and capturing images from multiple angles. This dimensional expansion allows simultaneous measurement of distance, slope, undulations, unevenness, and turf characteristics, comprehensively capturing terrain features that single-dimensional devices cannot detect.
2Reliability
If comprehensive terrain details (slope, undulations, unevenness, turf changes) are captured, then the path planning accuracy is improved, but the device complexity and data processing requirements increase
Solution Approach 1:
The patent segments the terrain measurement task into multiple specialized functions: structured light projection for slope measurement, visible light imaging for undulation detection, and multi-angle photography for unevenness and turf change identification. Each module focuses on specific terrain features, allowing comprehensive data collection while managing device complexity through functional decomposition and specialized sensor arrays.
3Productivity
If automated path planning algorithm is used, then the productivity and path optimization are improved, but the computational time and processing complexity increase
Solution Approach 1:
The patent performs preliminary actions by pre-processing terrain data during the scanning phase, organizing spatial information into structured formats that facilitate rapid algorithmic processing. The system pre-calculates potential path candidates and pre-processes elevation data, so that when the path planning algorithm executes, it operates on already-organized information, reducing computational time and improving overall productivity.
