Transparent Plant Cultivation Medium Using Gellan Gum
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transparent bases used in sealed containers for plant cultivation have poor adhesiveness, leading to plant damage during transportation and affecting aesthetic appeal when additional gels or adhesives are used to enhance adhesion, resulting in reduced transparency and uniformity.
Innovation Solution
A method involving a transparent base solidified with gellan gum in a nutritional liquid, with a pH value of 3.5-10.0 and soluble salt content below 0.5ms/cm, is used to create a secure adhesion within the container, maintaining transparency and uniformity, and the base is sterilized and treated to adhere securely to the container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If transparent base is used in sealed container for plant cultivation, then aesthetic appeal is improved, but adhesiveness deteriorates causing plant damage during transportation
Solution Approach 1:
The patent applies parameter changes by precisely controlling the concentration of gellan gum (8-10g/L) and pH value (3.5-10.0) of the transparent base to achieve optimal balance between transparency and adhesiveness. This quantitative parameter optimization allows the base to maintain both aesthetic appeal and secure adhesion to container walls, resolving the contradiction between transparency and adhesiveness.
Solution Approach 2:
The patent uses composite materials by combining gellan gum with transparent nutritional liquid to create a transparent base that possesses both optical clarity and adhesive properties. The gellan gum forms a gel network within the nutritional liquid, creating a composite structure that simultaneously provides transparency for aesthetic appeal and adhesiveness for secure container attachment.
2Reliability
If additional gels or adhesive materials are added to enhance adhesiveness, then adhesiveness is improved, but transparency and uniformity deteriorate
Solution Approach 1:
The patent avoids the transparency-deteriorating effect by changing the parameter of adhesive material selection - using gellan gum at a specific concentration range (8-10g/L) and controlling pH (3.5-10.0). This parameter optimization ensures the adhesive components remain transparent at effective concentrations, unlike conventional adhesives that become visible and disrupt uniformity when added.
Solution Approach 2:
The patent maintains homogeneity by using gellan gum, which forms a uniform gel structure throughout the transparent nutritional liquid without creating visible heterogeneities. The gel network distributes evenly at the specified concentration, providing consistent adhesiveness while preserving optical uniformity and transparency throughout the base.
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 method ensures the transparent base securely adheres to the container, preventing sliding or dispersion, even under shaking, and supports healthy plant growth with improved aesthetic appeal, allowing for secure cultivation and observation of plant growth.
Implementation Method 1
The base for cultivating plants in a transparent sealed container is mainly obtained by solidifying a mixture formed by adding gellan gum to a transparent nutritional liquid
Implementation Method 2
sterilizing the transparent container obtained in Step S22 at a temperature of 122±2°C and a pressure of 1.06±0.02 Kg/cm2

AI summary
Provided are a method for cultivating a plant in a transparent sealed container and a medium therefor. A transparent nutrient solution and a gellan gum are mixed, and then the mixture gels to form the medium. An amount of the gellan gum added to the nutrient solution is 2-10g/L. The medium has a pH value of 3.5-10.0. The gellan gum serves as a sole transparent gelling agent, thereby ensuring uniformness and transparency of the transparent medium. Moreover, the gellan gum possesses good adherence, such that the medium can be securely adhered to a transparent sealed container. An experiment proved that when the transparent sealed container experiences a normal degree of shaking, the medium does not slide or break apart. Moreover, the medium remains unseparated from the transparent sealed container after the transparent sealed container has been inverted for 3-10 minutes.
