Air movement control and air source device for cultivation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current plant cultivation systems face challenges in controlling air movement uniformly across entire planting areas, leading to uneven growth and reduced commercial output, as wind and air current distribution are difficult to stabilize, causing plants near wind generators to grow better than those farther away, and vertically oriented plants experience reduced growth due to carbon dioxide concentration gradients.
Innovation Solution
An air movement control system utilizing air velocity retention devices (AVRDs) and air source devices that maintain constant carbon dioxide concentration and air speed, incorporating bladeless fans to regulate air direction and speed, ensuring consistent air flow across vertically oriented crop rails, thereby addressing the uneven growth issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If wind generators are used to provide air movement for plant cultivation, then carbon dioxide distribution is improved, but uneven growth occurs across different areas of the planting system
Solution Approach 1:
The planting system is divided into multiple levels or zones, with wind generators strategically positioned to serve specific segments. This segmentation allows for localized control of air movement and carbon dioxide distribution, ensuring that each area receives adequate airflow without creating excessive variation between regions.
Solution Approach 2:
Different areas of the planting system are provided with tailored air movement characteristics. Wind generators are positioned and configured to create appropriate airflow patterns for specific zones, allowing each local area to receive optimal carbon dioxide supply while maintaining overall system uniformity.
2Productivity
If air movement is increased to enhance carbon dioxide supply for photosynthesis, then plant growth rate is improved, but temperature stability deteriorates
Solution Approach 1:
Wind generators operate in periodic cycles rather than continuously, providing bursts of air movement to replenish carbon dioxide supply. This periodic operation allows the system to maintain temperature stability between cycles while still achieving adequate carbon dioxide distribution and supporting healthy plant growth rates.
Solution Approach 2:
The system maintains continuous plant growth conditions by coordinating air movement cycles with temperature management. Multiple wind generators are positioned to ensure that while some areas experience air movement for carbon dioxide supply, other areas provide thermal stability, creating a continuous favorable environment for photosynthesis and growth.
3Productivity
If planting area is expanded to increase commercial output, then productivity is improved, but air movement control becomes more difficult
Solution Approach 1:
Large planting areas are divided into smaller manageable zones, each served by its own wind generator or group of generators. This segmentation allows for simplified control of air movement in each zone while collectively covering the entire expanded planting area, maintaining productivity without excessive system complexity.
Solution Approach 2:
Rather than attempting to uniformly control air movement across the entire expanded planting area, the system uses multiple wind generators to provide localized air movement in specific zones. This partial action approach simplifies control while still achieving adequate carbon dioxide distribution across the full planting area for increased commercial output.
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 ensures consistent air speed and carbon dioxide distribution, enhancing plant growth by maintaining optimal air flow and temperature, preventing dwarfing or death of plants, and increasing commercial output by utilizing air currents to evenly distribute carbon dioxide throughout the planting area.
Implementation Method 1
Air current, referring to the movement of air in the perpendicular (vertical) direction. It is involved in the formation of clouds, rain, drought, etc.
Implementation Method 2
Wind is an important factor for plant growth. In addition to helping to pollinate crops and distribute seeds, wind also plays an important role in the growth of plants, helping to carry carbon dioxide for photosynthesis.
Implementation Method 3
The presence of carbon dioxide in the air helps plant growth. The invention provides a fan in two key positions, one to assist in controlling the wind (the fan in the ventilation duct adjacent to the root of the plant), and another fan in a plant compartment for ventilating by blowing air back into an intake tube.

AI summary
An air movement system for plant cultivation. An air conditioner receives a gas mixture of air and carbon dioxide, regulates a temperature of the gas mixture, and outputs the gas mixture at the regulated temperature. A first bladeless fan receives the gas mixture output by the air conditioner and supplies the gas mixture as an air flow to a first crop area at a velocity towards an air intake. At least one second bladeless fan assists the air flow from the first crop area to a second crop area so as to maintain the velocity towards the air intake.
