Micro Stream Emitter with Dual Outlet Ports for Root Zone Irrigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current drip irrigation systems face issues such as overwatering leading to root decay, restricted root growth, accessibility for rodents, lack of foliage cleaning, humidity creation, and visibility problems, while mist irrigation systems require varied pinhole diameters and are prone to clogging.
Innovation Solution
A micro stream emitter with two geometries of water outlet ports providing a flat stream and downstream spray, offering uniform distribution and pressure compensation, creating a larger wetted area suitable for root growth and varying topography, and built-in pressure compensation for consistent water output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If drip irrigation delivers water to a precise point at low volume flow rate, then water is applied efficiently to plants, but root growth is restricted and roots may die back due to lack of oxygen from overwatering
Solution Approach 1:
The emitter is divided into multiple outlet ports (at least three) arranged in different directions, with each port delivering water to different areas around the plant. This segmentation distributes water more widely rather than concentrating it at a single point, improving oxygen availability to roots while maintaining efficient water application.
Solution Approach 2:
Different outlet ports are positioned at different heights and angles to deliver water to different local zones around the plant base. This creates varied local water distribution patterns that prevent water accumulation in any single spot, reducing root suffocation while ensuring comprehensive coverage of the root zone.
2Device complexity
If only one or two emitters are placed per plant, then the system is simple, but root growth is restricted and plant growth becomes stunted
Solution Approach 1:
A single emitter unit incorporates multiple outlet ports (at least three) that function collectively to serve the entire plant, replacing the need for multiple separate emitters. This segmentation within one device provides comprehensive water distribution across the root zone while maintaining system simplicity.
Solution Approach 2:
The multi-port emitter performs multiple functions simultaneously: it distributes water to different areas around the plant, creates humidity through evaporation, and provides visual indication of operation. This multi-functionality allows one emitter to replace what would otherwise require multiple separate devices.
3Ease of manufacture
If drip emitters are buried in the soil, then they are hidden from view, but rodents can easily access them and drink the water
Solution Approach 1:
The emitter is positioned above ground level rather than buried in the soil, utilizing the vertical dimension to place the water delivery point out of reach of ground-dwelling rodents. This dimensional change maintains installation simplicity while eliminating rodent access to the water source.
4Adaptability or versatility
If mist irrigation is used to create humidity and wet area, then plant atmosphere is improved, but different plants require different pinhole diameters and the system is prone to clogging
Solution Approach 1:
The emitter creates humidity as a secondary effect through evaporation from multiple outlet ports, rather than relying on fine mist generation. This partial action approach provides sufficient humidity for most plants without requiring the complex pinhole configurations and filtered water supplies needed for true mist systems, reducing clogging risks.

AI summary
The micro stream emitter include a body having two different geometries water outlet ports providing downward stream into the soil wetting the root zone and with the second geometries water outlet wetting the surrounding plants area. The internal passage of the emitter shown a the lower passage supplying water to the lower ports that actually uses top wall with a annular depression, forming a diaphragm enabling the water to reflex into the lower port outlets. Similar to the internal lower passage the upper passage with includes a smaller diameter passage uses top wall with an annular depression, forming a diaphragm enabling the water to reflex into the upper port outlets.
