Indoor Grow Cabinet Ventilation and UV Sterilization Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plant cultivation apparatuses face issues with contamination of culture solution, leading to mold or green algae growth, and inadequate ventilation, which compromises sanitation and cultivation control.
Innovation Solution
The apparatus incorporates an inlet duct for air circulation, an outlet duct for air discharge, and a light assembly with UV sterilization for the water tank, along with temperature and moisture control features to maintain separate cultivation spaces and improve sanitation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the culture solution is supplied to the entire tray, then the plant growth is supported, but the culture solution is exposed to the outside and thus is contaminated
Solution Approach 1:
The patent introduces a culture solution supply unit with a nozzle that acts as an intermediary device to deliver culture solution directly to the root zone through the tray bottom, preventing exposure to the external environment while maintaining effective supply
2Temperature
If a closed environment is provided in a temperature region in which the plants are grown, then the temperature control is improved, but the culture solution is very easily contaminated
Solution Approach 1:
The nozzle system serves as an intermediary that enables closed-environment temperature control while preventing contamination by delivering culture solution through the tray bottom, isolating the solution from the external environment
Solution Approach 2:
The tray bottom acts as a flexible barrier that allows culture solution to pass through to the root zone while preventing contamination from the external environment, maintaining both temperature control and sanitation
3Adaptability or versatility
If the cultivation space is divided into a plurality of spaces, then the cultivation control is improved, but the device complexity is increased
Solution Approach 1:
The patent divides the cultivation space into multiple independent trays, each capable of receiving culture solution separately through individual nozzles, enabling independent control while maintaining a relatively simple overall structure
Solution Approach 2:
The supply unit is designed with multiple nozzles that can serve multiple trays simultaneously, providing universal functionality that enables independent control of multiple spaces without proportionally increasing system complexity
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
This design prevents contamination, enhances ventilation, and allows for independent temperature control in different cultivation regions, ensuring improved sanitation and efficient plant growth.
