Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural technologies lack a system to image the seed trench in real-time to verify critical factors such as seed depth, spacing, and residue, and adjust planters automatically for uniform seed emergence and high yields.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If spot checks of the seed trench are conducted to verify critical factors, then some assurance of proper planting conditions is obtained, but only conditions at specific locations are identified and real-time verification during planting operations is not achieved
Solution Approach 1:
The patent replaces manual spot-checking methods with an electromagnetic sensing system that automatically images the seed trench. The system uses electromagnetic fields to detect soil properties, seed placement, and trench conditions, substituting mechanical verification with field-based electromagnetic measurement for continuous real-time monitoring during planting operations
Solution Approach 2:
The patent introduces an electromagnetic field as an intermediary between the planting system and the verification process. The electromagnetic field penetrates the soil to image the seed trench, acting as a mediator that enables non-contact, real-time detection of planting parameters without interfering with the planting operation
2Loss of information
If manual inspection methods are used to verify planting conditions, then some information about seed placement is obtained, but automatic or remote adjustment of the planter while on-the-go is not enabled
Solution Approach 1:
The patent implements a feedback loop where electromagnetic sensors continuously image the seed trench, the controller analyzes the images to detect planting deviations, and the system automatically adjusts planter components in real-time. This closed-loop feedback enables automatic correction of planting parameters during field operations
Solution Approach 2:
The system enables the planter to self-correct planting deviations by automatically adjusting its own components based on real-time electromagnetic imaging feedback, eliminating the need for manual intervention and allowing the planting system to optimize its performance autonomously during operation
3Measurement precision
If electromagnetic fields are generated through the work layer to produce images, then soil characteristics can be sensed, but the system complexity increases with multiple transmitters and receivers
Solution Approach 1:
The patent makes the electromagnetic sensor system multi-functional by enabling it to detect multiple soil properties (moisture, density, organic matter, temperature) and planting parameters (seed depth, spacing, trench conditions) using the same electromagnetic field generation and detection mechanism, reducing the need for separate specialized sensors for each parameter

AI summary
A soil sensing system (500; 1200) for sensing soil properties includes an implement (1240) and one of a radar transceiver (100; 100A; 100B; T; T1; T2; T3; R; R1; R2; R3) or a combination of radar transmitter (100; 100A; 100B; 1252; T; T1; T2; T3) and a radar receiver (100; 100A; 100B; R; R1; R2; R3) disposed on the implement for sensing soil properties at a depth of soil. The system also has at least one optical sensor (1252) to sense at least one of soil organic matter, soil moisture, soil texture, and soil cation-exchange capacity (CEC). The implement may be an agricultural implement and may be a planter.
