Solution Overview
Problem
Conventional irrigation systems for horticulture are inefficient, prone to waterborne diseases, voluminous, and typically suited for monoculture, with high water and nutrient wastage, complex maintenance, and scalability issues.
Innovation Solution
An automated irrigation system that prepares and transports batches of irrigating medium to specific zones based on plant needs, using a conduit system with a valve and flow control unit to evacuate each batch integrally, allowing for scalable, redundant, and flexible operation with minimal mixing and reduced waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional irrigation systems (NFT or E&F) are used to provide abundant irrigating medium to substrate, then plants receive sufficient water and nutrients, but 90% of the irrigating medium is drained away representing significant water and nutrient wastage
Solution Approach 1:
The irrigation system is divided into multiple independent conduits, each capable of transporting a separate batch of irrigating medium to specific plant zones. This segmentation allows precise control over water and nutrient delivery to different locations simultaneously, enabling efficient resource utilization without excessive drainage.
Solution Approach 2:
The system employs dynamic valve control to switch between different conduits and batches of irrigating medium. The valve system can dynamically route different compositions of irrigating medium to different zones based on real-time plant needs, optimizing water and nutrient usage while minimizing waste through adaptive flow management.
2Productivity
If conventional irrigation systems provide continuous flow of irrigating medium, then plants are continuously irrigated, but energy is consumed for providing unused irrigating medium and additional drainage systems are required
Solution Approach 1:
Instead of continuous flow, the system uses periodic batch-wise irrigation through controlled valve operations. Each conduit can be filled with a batch of irrigating medium and then sealed or isolated, allowing periodic delivery to specific zones. This reduces continuous energy consumption for pumping while maintaining effective irrigation through targeted periodic supply.
Solution Approach 2:
The system extracts and isolates unused irrigating medium from the main flow path by using sealed conduits and valve control. Rather than allowing continuous drainage, the system can retain batches in sealed conduits for later use or dispose of them efficiently, eliminating the need for extensive drainage infrastructure and reducing associated energy consumption.
3Ease of operation
If conventional irrigation systems are designed for monoculture with single type of irrigating medium, then the system is simple to operate, but it cannot accommodate multiple plant types with different irrigation needs
Solution Approach 1:
The conduit system is designed with multiple conduits that can each transport different compositions of irrigating medium to different zones. The valve system provides universal control capability, allowing any conduit to be routed to any zone as needed. This multi-functional design enables the same infrastructure to support monoculture and polyculture operations, accommodating various plant types with their specific irrigation requirements.
Solution Approach 2:
The dynamic valve control system allows flexible reconfiguration of the irrigation network. Conduits can be dynamically assigned to different zones and different medium compositions based on current cultivation needs. This dynamic adaptability enables the system to transition between monoculture and polyculture modes, serving different plant types without requiring physical reconfiguration of the infrastructure.
4Loss of substance
If aeroponics is used to grow plants without substrate in closed environment, then water and nutrient wastage is reduced, but the system is complex and time consuming not scalable to industrial scale
Solution Approach 1:
The system segments the irrigation function into separate conduits that can be independently controlled and filled with batches of irrigating medium. This segmentation simplifies the overall system architecture compared to fully integrated aeroponic systems, while still achieving efficient water and nutrient retention through controlled delivery to plant zones without requiring complex closed-loop recirculation infrastructure.
5Loss of substance
If drip irrigation system is used to provide slow drip onto plant roots, then water and nutrient wastage is reduced, but the system is voluminous and heavy requiring high maintenance
Solution Approach 1:
The system uses segmented conduits that can be filled with batches of irrigating medium and sealed, eliminating the need for continuous drip infrastructure. This segmentation approach reduces the overall system volume and weight while maintaining water and nutrient efficiency through controlled batch delivery. The sealed conduit system also reduces maintenance requirements compared to continuous drip systems that are prone to clogging and leakage.
