Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flood irrigation systems face inefficiencies due to variations in surface contour, soil type, and subsurface geology, leading to uneven water distribution and difficulty in monitoring water presence and soil moisture across farm fields, which results in wasted water and time.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If traditional flood irrigation is used without monitoring, then water is applied to the field, but water distribution becomes uneven and water is wasted due to lack of information on water presence and soil moisture
Solution Approach 1:
The patent implements feedback by deploying sensors throughout the field that continuously monitor water presence and soil moisture levels, then transmit this information back to the irrigation control system. This feedback loop enables the system to adjust irrigation operations in real-time based on actual field conditions, preventing both over-irrigation and under-irrigation, thereby eliminating water waste while maintaining optimal soil moisture levels.
Solution Approach 2:
The patent replaces traditional mechanical irrigation management (visual inspection, manual measurement) with electronic sensing and wireless communication systems. Sensors detect water presence and soil moisture electronically, and this data is transmitted wirelessly to the control system, eliminating the need for manual field measurements and enabling automated irrigation decisions that prevent water waste.
2Loss of time
If manual monitoring of irrigation progress is used, then farmers can observe water movement, but this requires significant labor time and cannot provide real-time data across the entire field
Solution Approach 1:
The patent replaces manual visual monitoring with an automated network of electronic sensors distributed throughout the field. These sensors continuously detect water presence and soil moisture conditions and transmit data wirelessly to the irrigation control system, eliminating the need for farmers to physically walk through fields and manually record observations, thereby saving labor time while improving irrigation management efficiency through real-time automated monitoring.
Solution Approach 2:
The irrigation monitoring system operates autonomously without requiring continuous human intervention. Sensors automatically detect field conditions, process the data, and provide real-time information to the irrigation control system, enabling the system to self-regulate irrigation operations based on actual field conditions, thereby eliminating manual monitoring labor while maintaining high productivity.
3Device complexity
If uniform irrigation is applied across the entire field, then water management is simplified, but variations in surface contour, soil type, and subsurface geology cause uneven water distribution and drainage
Solution Approach 1:
The patent implements local quality by deploying sensors at multiple locations throughout the field to detect local variations in water presence and soil moisture. The irrigation control system uses this localized data to apply water differently in different zones of the field, matching the specific needs of each area caused by variations in surface contour, soil type, and subsurface geology. This enables precise water distribution that accounts for local conditions while maintaining overall system manageability.
4Ease of manufacture
If farmers lack real-time irrigation data, then irrigation operations can proceed without monitoring equipment, but farmers cannot make informed decisions to optimize water use and reduce costs
Solution Approach 1:
The patent replaces the absence of monitoring information with an automated electronic sensing and wireless communication system. Sensors distributed throughout the field continuously detect water presence and soil moisture levels, and this data is transmitted wirelessly to the irrigation control system and farmer interfaces, providing real-time information without requiring complex manual measurement procedures, thereby maintaining ease of implementation while delivering comprehensive real-time irrigation data for informed decision-making.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enables efficient water management by ensuring consistent water distribution, reducing waste and labor costs, and providing farmers with comprehensive data for optimal irrigation practices.
Implementation Method 1
The sensor circuit includes the battery and an activator (which may be the microprocessor) such that in absence of surrounding water an electrical potential exists between the external conductor probes, without current flow, but in the presence of surrounding water the circuit is closed
Implementation Method 2
In a preferred form the sensor communicates by long-range WiFi (LORA) or similar long-range wireless communication

AI summary
An irrigation management system monitors irrigation parameters, including progress of flood irrigation water admitted onto a farm field, water levels in ditches, basins or boxes, soil moisture, water usage and other important factors. In flood irrigation a series of small, inexpensive sensors detect the presence in each of the sensor locations in a field, and each sends a signal when water first reaches the sensor. In a preferred form the sensor communicates by long-range radio communication either directly with a hub or gateway, or by sending a transmission that is relayed from location to location and ultimately to the hub or gateway. All aspects of irrigation water need, availability, task completion, pipe and equipment status, and water usage are monitored and communicated to the farmer. The system allows efficient water management and reliable and responsible irrigation at all irrigated fields.
