Solution Overview
Problem
Conventional soil and water sensors can only measure a single parameter at a time and are unable to accurately determine multiple parameters at different depths, limiting their effectiveness in comprehensive soil and water analysis.
Innovation Solution
A modular sensor system with a vertically stacked arrangement of interconnected sensors through a bus network, where each sensor rod can measure multiple parameters and communicate results to a sensor bus head, enabling analysis of environmental and chemical parameters at various depths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sensors are used to measure different parameters, then the quantity of parameters that can be measured increases, but the ability to determine parameters at different levels is lost
Solution Approach 1:
The sensor system is divided into multiple discrete sensor rods, each positioned at different depths. Each rod contains specific sensors for measuring parameters at its particular depth level, enabling both multi-parameter measurement and depth-resolved analysis simultaneously.
Solution Approach 2:
The system transitions from horizontal placement of multiple sensors to a vertical stacking arrangement. By organizing sensors along the depth dimension, the system achieves both multiple parameter measurement and depth differentiation in a single integrated structure.
2Productivity
If one sensor measures only one parameter, then the device complexity is low, but the productivity of comprehensive analysis is reduced
Solution Approach 1:
Multiple sensor rods are combined into a single integrated sensor system that measures multiple parameters simultaneously at different depths. The rods are connected through a shared communication and power infrastructure, enabling comprehensive analysis while managing system complexity through modular integration.
Solution Approach 2:
The sensor rods are designed as universal modules that can measure multiple parameters (temperature, moisture, pH, conductivity, etc.) depending on the specific sensors incorporated in each rod, allowing flexible configuration for comprehensive soil and water analysis.
3Quantity of substance
If sensors are placed at different depths, then the measurement coverage is improved, but the difficulty of detecting and measuring increases
Solution Approach 1:
The system incorporates feedback mechanisms where sensors at different depths communicate their measurements to a central processing unit. This enables real-time monitoring and adjustment of measurement parameters, facilitating accurate detection across multiple depth levels.
Solution Approach 2:
A central communication and control unit acts as an intermediary between sensors at different depths and the external system. This mediator handles signal transmission, data processing, and coordination, simplifying the detection and measurement process across the distributed sensor array.

AI summary
A modular sensor system may perform soil and water analysis at various depths. For instance, chemical composition may be determined and concentration and/or environmental parameters, such as pressure, temperature, and/or moisture, may be measured at different depths. A sensor bus head, at least one sensor rod, and a sensor bus terminus may be vertically stacked and interconnected through a bus network such that the system is modular and reconfigurable.
