Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing forestry vehicles face challenges in accurately measuring and manually calculating tree density and position in forest areas, leading to inconsistent thinning results due to operator-dependent methods and environmental obstacles like foliage and terrain, which can be time-consuming and error-prone.
Innovation Solution
A forestry vehicle equipped with a tree detection device, such as a stereo camera or lidar, mounted to detect trees within a grid, combined with GNSS for positioning, automatically updates tree density data on a display, reducing manual input and improving accuracy by positioning trees in a grid system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual measurement and calculation methods are used by operators, then flexibility and adaptability to various terrain and weather conditions are maintained, but measurement precision and consistency deteriorate due to operator-dependent methods
Solution Approach 1:
The patent replaces manual mechanical measurement methods with an automated optical detection system. A camera captures images of trees, and an image processing unit automatically analyzes these images to determine tree positions, diameters, and densities. This substitution eliminates operator-dependent variability while maintaining adaptability to various terrain and weather conditions through automated image capture and analysis.
Solution Approach 2:
The system enables self-service measurement by automatically capturing images and processing them to extract tree parameters without requiring operator intervention in the measurement process. The image processing unit autonomously identifies tree positions, calculates diameters, and determines density, allowing the system to serve itself in performing measurements that previously required skilled operators.
2Measurement precision
If automated tree detection systems are implemented, then measurement precision and consistency are improved, but device complexity increases due to additional detection and processing equipment
Solution Approach 1:
The camera serves multiple functions: it captures images for tree detection, provides visual records for verification, and can potentially be used for other forestry monitoring tasks. The image processing unit performs multiple analysis functions including position identification, diameter measurement, and density calculation, reducing the need for separate specialized devices for each measurement task.
Solution Approach 2:
The system creates a digital copy of the forest scene through image capture, allowing virtual analysis and measurement without physically interacting with the trees. This digital replica enables repeated measurement and analysis without additional field equipment or disturbance to the forest environment.
3Device complexity
If manual tree measurement and selection is performed, then system simplicity is maintained, but productivity deteriorates due to time-consuming operations
Solution Approach 1:
The patent replaces time-consuming manual measurement operations with automated image-based detection. The camera captures multiple trees simultaneously, and the image processing unit rapidly analyzes all trees in the field of view, determining positions, diameters, and suitability for thinning. This parallel processing capability dramatically increases productivity compared to sequential manual measurement of individual trees.
Solution Approach 2:
The system measures and analyzes all trees within the camera's field of view, rather than selectively measuring only specific trees. This excessive action of measuring everything enables rapid data collection that can then be filtered and processed to identify trees suitable for thinning, improving overall operational efficiency.
4Adaptability or versatility
If operator experience and judgment are relied upon for tree selection, then adaptability to complex forest conditions is maintained, but reliability deteriorates due to inconsistent results between operators
Solution Approach 1:
The patent replaces subjective operator judgment with objective image-based analysis. The system consistently applies the same measurement and selection criteria to all trees based on captured images, eliminating variability between different operators. The automated processing ensures that trees meeting the thinning criteria are identified consistently regardless of who operates the system.
Solution Approach 2:
The system provides visual feedback through displayed images and processed results, allowing operators to verify and adjust the automated measurements and selections. This feedback mechanism ensures that the automated system's results align with expert judgment while maintaining consistency across different operations and operators.
