Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soilless cultivation media face challenges in providing adequate aeration and water retention, leading to issues such as water stagnation and root degradation in high porosity media, or poor ventilation and development in low porosity media, resulting in reduced plant yields.
Innovation Solution
A culture support with a rectangular parallelepiped-shaped bread of plant material having vertical grooves on its side faces for aeration and excess water evacuation, housed in a light-tight bag with slots for ventilation, and coated with latex to maintain groove integrity, ensuring continuous watering and aeration for optimal root growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If high porosity bread is used, then aeration capacity is improved, but water retention capacity deteriorates
Solution Approach 1:
The culture bread is segmented into zones with different porosity levels. The upper zone has higher porosity for better aeration, while the lower zone has lower porosity for better water retention. This segmentation allows each zone to optimize its function without compromising the other.
Solution Approach 2:
Different regions of the culture bread are given different physical properties. The upper portion maintains high porosity for root aeration, while the lower portion has reduced porosity to retain water. This local differentiation of quality resolves the contradiction between aeration and water retention.
2Quantity of substance
If frequent watering is applied to high porosity bread, then water supply is improved, but water stagnation and root degradation occur
Solution Approach 1:
The culture bread is divided into functional zones where the lower zone acts as a water reservoir with controlled porosity, preventing water stagnation while ensuring adequate supply to the upper zone where roots develop. This segmentation prevents harmful water accumulation.
Solution Approach 2:
The lower zone of the culture bread serves as an intermediary between the irrigation system and the root zone, regulating water flow and preventing both stagnation and deficiency. It mediates the water supply to match root needs.
3Quantity of substance
If low porosity culture bars are used, then water retention capacity is improved, but aeration capacity deteriorates
Solution Approach 1:
The culture bread is segmented vertically with the lower zone having low porosity for water retention and the upper zone having high porosity for aeration. This spatial segmentation allows both contradictory requirements to be satisfied in different regions.
Solution Approach 2:
Different porosity qualities are assigned to different locations within the culture bread. The lower region has low porosity for water storage, while the upper region has high porosity for air circulation, optimizing both functions locally.
4Quantity of substance
If poor ventilation is maintained in low porosity media, then water retention is improved, but root development deteriorates
Solution Approach 1:
The culture bread is divided into ventilation zones (upper high porosity region) and water retention zones (lower low porosity region), allowing roots to access both adequate air and water without compromise to productivity.
Solution Approach 2:
The upper portion of the culture bread provides high aeration quality for root development, while the lower portion provides high water retention quality, ensuring both conditions for optimal plant productivity are met in their respective locations.
