Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soil detection systems in agriculture are not user-friendly for farmers, as they require specialist personnel for data acquisition and evaluation, and do not allow for real-time soil information recording during agricultural work trips, limiting their flexibility and independence.
Innovation Solution
A device integrated into an agricultural working machine, featuring electromagnetic coils within a front or ballast weight, allows for real-time soil condition monitoring, using a modular design with shielding to minimize interference, and includes additional sensors for distance and inclination, enabling direct control of soil cultivation equipment based on detected soil parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If soil sensors are mounted on specially designed trailer systems pulled across test areas, then measurement quality can be maintained by keeping a large distance between the ground sensor and towing vehicle, but the system complexity and operational independence deteriorate as specialized personnel and separate survey drives are required
Solution Approach 1:
The patent combines the soil sensing system with the agricultural working machine itself, integrating the ground sensor, control unit, and communication interface into the working machine. This merging eliminates the need for separate trailer systems and specialized survey drives, allowing farmers to independently conduct soil analysis during regular field operations while maintaining measurement quality through the integrated design.
2Adaptability or versatility
If soil analyzers are positioned on the front part of agricultural machines for simultaneous soil analysis and cultivation, then operational flexibility improves, but electromagnetic interference from the machine may affect measurement accuracy
Solution Approach 1:
The patent introduces a shielding plate as an intermediary element positioned between the agricultural machine components and the ground sensor. This shielding plate blocks electromagnetic radiation from the machine, preventing interference with the sensor measurements while allowing the sensor to remain integrated with the machine for operational flexibility.
3Productivity
If transmitting and receiving coils are integrated into a front weight, then data collection during single pass improves productivity, but electromagnetic interference from the tractor may affect the sensitive electronic components
Solution Approach 1:
The patent uses a shielding plate positioned between the tractor and the sensor components in the front weight to block electromagnetic radiation from the tractor. This intermediary shielding protects the sensitive transmitting and receiving coils from interference, ensuring signal reliability while maintaining the integrated design that enables data collection during single-pass operations.
4Loss of information
If farmers use conventional soil sensor systems, then specialized personnel can perform detailed analysis, but the farmers lose independence and flexibility as data collection and analysis require separate specialized operations
Solution Approach 1:
The patent enables farmers to independently perform soil analysis by integrating the sensing system directly into their working machines. The system automatically collects soil data during field operations and transmits it to a terminal device, allowing farmers to access and analyze the data themselves without requiring specialized personnel or separate survey operations, thus achieving self-service capability.
