Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current irrigation management systems lack the ability to accurately detect and respond to the specific needs of individual plants or crops at different growth stages, often leading to inefficient water use and potential plant stress due to over or under watering.
Innovation Solution
A machine learning device that uses sensors and cameras to detect the growth stages of plants and adjust watering based on both the plant's stage and environmental conditions, incorporating a neural network to analyze images and sensor data for precise irrigation control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional irrigation management methods are used, then labor-intensive manual observation and intervention can be performed, but the precision and automation of irrigation control deteriorates
Solution Approach 1:
The patent replaces manual mechanical observation with automated machine learning-based detection systems. Cameras and sensors capture plant images and environmental data, which are then processed by neural networks to automatically determine growth stages, eliminating the need for manual field inspection while significantly improving detection precision.
Solution Approach 2:
The system enables self-service irrigation control by automatically detecting plant growth stages and environmental conditions, then autonomously adjusting irrigation schedules without human intervention. The machine learning model continuously learns from data to optimize irrigation decisions, making the system self-adapting and self-regulating.
2Measurement precision
If irrigation is based on cumulative water usage and soil conditions alone, then simple flow rate measurement can be used, but plant health assessment accuracy deteriorates
Solution Approach 1:
The patent merges multiple measurement approaches by combining visual inspection of plant leaves (health indicators) with soil moisture sensing and environmental monitoring. This integrated approach correlates plant appearance with soil and atmospheric conditions to comprehensively assess plant water status and health, providing more accurate irrigation guidance than any single method alone.
Solution Approach 2:
The system uses plant visual indicators (leaf color, turgor, curling) as intermediary markers to infer internal plant water status and health. These observable external characteristics serve as mediators that translate complex internal physiological states into measurable signals that can guide irrigation decisions.
3Productivity
If irrigation scheduling does not consider plant growth stages, then uniform watering can be applied, but water use efficiency deteriorates
Solution Approach 1:
The patent implements dynamic irrigation scheduling that adapts to changing plant growth stages. As plants progress through different developmental phases (seedling, vegetative, flowering, fruiting), the system adjusts irrigation requirements accordingly, recognizing that water needs vary dynamically throughout the growing season rather than remaining static.
Solution Approach 2:
The system applies differentiated irrigation strategies tailored to specific growth stages and individual plant locations. Rather than uniform field-wide irrigation, it customizes watering schedules based on the local needs of plants at different developmental stages and micro-environmental conditions, optimizing water use efficiency for each zone.
4Reliability
If over-watering is prevented by monitoring cumulative usage, then water conservation can be achieved, but plant stress from under-watering increases
Solution Approach 1:
The system employs feedback loops where plant growth stage detection and environmental monitoring continuously inform irrigation decisions. Real-time data on plant health indicators, soil moisture, temperature, and humidity feed back to the control system, which adjusts irrigation timing and amounts to maintain optimal plant water status, preventing both over-watering and under-watering through continuous adaptation.
