Segmented Air Emission Units for Plant Leaf Transpiration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plant cultivating facilities face issues with uneven air circulation, leading to strong winds damaging plants near the blast fan and inadequate carbon dioxide distribution, resulting in tip burn and hindered transpiration.
Innovation Solution
An air emission device with multiple units emitting air flows rich in humidity and carbon dioxide, equipped with fans and light emitting devices, specifically targeting new leaves to promote transpiration and growth while inhibiting stem growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a blast fan outputs strong wind to circulate air through the entire cultivating chamber, then air circulation is achieved, but plants near the fan receive excessive wind causing damage
Solution Approach 1:
The cultivating chamber is divided into multiple regions with individual air emission units positioned above each plant or plant group. Each unit independently controls air flow to its specific target area, replacing the single large fan system with multiple small localized units.
Solution Approach 2:
Air emission units are positioned directly above each plant to provide localized air circulation tailored to individual plant needs. This ensures uniform air flow distribution without creating excessive wind speeds that would damage plants, as each unit operates independently at optimal low speed.
2Productivity
If a blast fan circulates air through the entire cultivating chamber, then air flow is generated, but plants far from the fan receive insufficient carbon dioxide
Solution Approach 1:
The air circulation system is segmented into multiple independent emission units distributed throughout the chamber. Each unit is positioned above specific plants and delivers air directly to them, ensuring all plants receive adequate carbon dioxide regardless of their distance from any single air source.
Solution Approach 2:
Air is supplied through a network of pipes that act as intermediaries, distributing carbon dioxide-rich air from a central source to multiple localized emission units. This pipe network ensures uniform distribution of carbon dioxide to all plants throughout the chamber.
3Device complexity
If a single blast fan is used for air conditioning, then the system structure is simple, but uniform air distribution to all plants cannot be achieved
Solution Approach 1:
The air conditioning system is divided into multiple simple air emission units rather than one complex large fan system. Each unit has a straightforward structure with a fan and housing, making individual units simple to manufacture while the collective system achieves uniform distribution through their distributed arrangement.
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
Uniform air circulation and targeted nutrient delivery prevent tip burn and wilting, enhance leaf growth, and improve the commercial value of plants by optimizing carbon dioxide supply and light exposure.
Implementation Method 1
By this air circulation, transpiration is promoted and suction of water and nutrients from the roots can be promoted
Implementation Method 2
The photonic synthesis can be promoted by adjusting the concentration of the carbon dioxide to thereby promote growth of plants

AI summary
The air emission device for growing plants includes a plurality of air emission units for respectively emitting an air flow onto the new leaves growing on a tip of a stem of each plant that has one stem. The transpiration effect on the leaves and suctioning of water and nutrition from the roots of the plants can be promoted. Thus, wilting of leaves can be prevented and the tip burn due to insufficient calcium can be avoided. Provision of the air emission units are effectively arranged to evenly or uniformly supply air onto the new leaves of the each plant.
