Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plant cultivation apparatuses face issues with contamination, inadequate ventilation, pest penetration, dew condensation, and lack of carbon dioxide supply, leading to unsanitary conditions and inefficient growth environments.
Innovation Solution
The apparatus incorporates a suction duct for external air intake, a discharge duct for air circulation, and a sealed door system with a gasket to prevent contamination and pest entry, while ensuring ventilation and carbon dioxide supply through external air, and includes an evaporator and blower assembly for temperature control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the cabinet is sealed to prevent contamination and pest entry, then sanitation is improved, but dew condensation occurs inside the cultivation space
Solution Approach 1:
A sealed door with gasket creates a flexible barrier that prevents contamination and pest entry while maintaining the enclosed cultivation environment, allowing controlled ventilation without compromising sanitation
Solution Approach 2:
The ventilation system adjusts air flow parameters to balance moisture removal with prevention of dew condensation, changing the humidity and air exchange rates to maintain optimal conditions inside the sealed cabinet
2Object-affected harmful factors
If the cabinet is sealed to prevent pest penetration, then sanitation is improved, but carbon dioxide supply becomes insufficient
Solution Approach 1:
The sealed door with gasket acts as a selective barrier that blocks pests while allowing controlled gas exchange through the ventilation system, maintaining both sanitation and carbon dioxide supply
Solution Approach 2:
The ventilation system serves as an intermediary mechanism that facilitates carbon dioxide entry and moisture removal without requiring an open structure that would allow pest penetration
3Productivity
If the nutrient solution is circulated through the recovery container, then water supply efficiency is improved, but contamination occurs
Solution Approach 1:
The drainage and recovery container system extracts and separates used nutrient solution from the cultivation environment, allowing it to be recovered and reused while preventing contamination of the growing plants
Solution Approach 2:
The system implements feedback control by monitoring and adjusting nutrient solution flow based on plant needs and solution quality, optimizing water supply efficiency while maintaining sanitation through controlled circulation
