Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for collecting soil data on pH, organic matter, and electrical conductivity are costly, time-consuming, and inefficient, especially in large fields, as they often require manual sampling, stationary sensors, or slow-moving vehicle-mounted systems, which limit coverage and accuracy.
Innovation Solution
A system combining an unmanned aerial vehicle (UAV) with a multispectral sensor for aerial mapping and a mobile soil sensor system that moves over the field to collect data, using fixed sampling stations for calibration, and a computing system to correlate spectral images with soil property grids, allowing for efficient and accurate data collection and mapping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual acquisition of soil samples is used, then measurement precision can be maintained, but loss of time and productivity are significant
Solution Approach 1:
The patent uses spectral imaging to create a digital copy of soil properties across the field, replacing the need for physical manual sampling at every location. The spectral data serves as a virtual replica of soil characteristics, allowing rapid analysis without time-consuming field sampling operations.
Solution Approach 2:
The patent replaces manual mechanical soil sampling with automated spectral sensing systems. The spectral imaging technology substitutes for human operators physically collecting samples, enabling rapid, non-contact measurement of soil properties across large areas.
2Productivity
If vehicle-mounted soil sensor systems are used, then productivity improves, but device complexity and cost increase
Solution Approach 1:
The patent employs a multi-functional spectral imaging system that can measure multiple soil properties (organic matter, electrical conductivity, pH) simultaneously using a single sensor platform. This universal approach reduces overall system complexity compared to having separate specialized sensors for each soil parameter.
Solution Approach 2:
The patent introduces spectral reflectance as an intermediary measurement that indirectly indicates soil properties. Instead of directly measuring complex soil characteristics with complicated sensors, the system uses spectral signatures as a mediator to infer soil conditions, simplifying the measurement apparatus.
3Measurement precision
If stationary base stations are used, then measurement precision is maintained, but area coverage is limited
Solution Approach 1:
The patent transitions from two-dimensional stationary point measurements to three-dimensional spatial coverage by using aerial spectral imaging. The system captures data across the entire field surface from an elevated perspective, adding the dimension of aerial coverage to expand area measurement capability while maintaining precision through spectral analysis.
Solution Approach 2:
The patent divides the field into multiple spectral image segments that can be processed independently. The field is divided into grid cells or zones based on spectral characteristics, allowing precise measurement of each segment while collectively covering the entire area, thus maintaining precision through localized analysis while achieving broad coverage.
