Plate-Shaped Structure With Weighted Cap For Moisture Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing plate-shaped structures for plant cultivation lack enhanced functionality, particularly in retaining moisture and preventing evaporation, while also being susceptible to deformation and water loss.
Innovation Solution
The plate-shaped structure incorporates multiple cavities, a tapered drain opening with a cap heavier than water to facilitate water seepage into a reservoir, and a stay defining a predefined offset between the reservoir's interior side wall sections to maintain shape and orientation, along with protrusions and openings for secure attachment to the reservoir.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a drain opening is provided to allow water to drain into the reservoir, then water loss due to evaporation is reduced, but the structure becomes more complex and may allow uncontrolled water flow
Solution Approach 1:
A cap is introduced as an intermediary element in the drain opening. The cap selectively mediates between preventing evaporation and allowing drainage - it blocks the opening during dry periods to prevent evaporation, but allows water to pass through during rainfall, thus resolving the contradiction between evaporation prevention and controlled water flow
Solution Approach 2:
The cap is designed to be self-regulating based on water presence. When water accumulates in the reservoir, the cap automatically allows drainage; when the reservoir is dry, it automatically seals to prevent evaporation. This self-service mechanism eliminates the need for complex external control systems
2Loss of energy
If a cap is placed in the drain opening to prevent evaporation, then moisture retention is improved, but the cap may float or rotate compromising the closing function
Solution Approach 1:
The cap is designed with a weight greater than the weight of an equal volume of water, creating a downward force that counteracts buoyancy. This ensures the cap remains seated in the drain opening and cannot float away, maintaining reliable closing function while still allowing evaporation prevention
Solution Approach 2:
The cap has an asymmetric weight distribution with the center of mass positioned below the edge contact point with the sidewall. This asymmetric design creates a stable equilibrium that prevents rotation, ensuring the cap maintains its closing function regardless of water level changes
3Ease of manufacture
If the plate-shaped structure is made from paper material, then manufacturing cost is reduced, but the structure is susceptible to deformation under water weight and pressure
Solution Approach 1:
The drain opening sidewall is designed with a tapered, curved geometry rather than sharp angles. This curved form distributes water pressure more evenly across the paper structure, reducing stress concentration points that would cause deformation, while maintaining the low-cost paper material construction
Solution Approach 2:
The structure is divided into functional segments including the plate-shaped upper surface, the tapered drain opening, and the reservoir. This segmentation allows each component to be optimized for its specific function while using simple paper material, with the tapered drain opening specifically designed to handle hydraulic loads
4Adaptability or versatility
If multiple cavities are added to cultivate more plants, then functionality is increased, but the structure becomes more complex and harder to manufacture
Solution Approach 1:
The plate-shaped upper surface with multiple cavities serves multiple functions simultaneously: it provides structural support, creates individual cultivation zones for multiple plants, and integrates the drain opening system. This multi-functionality increases plant cultivation capacity without proportionally increasing manufacturing complexity

Function Achieved in This Case
This configuration effectively reduces moisture evaporation, allows for the cultivation of multiple plants, and enhances the structure's durability against wet conditions and weight, while maintaining airtight connections to prevent unwanted openings.
Implementation Method 1
a cap located freely in the drain opening, so as to allow water to seep down between the cap and the sidewall of the drain opening
Implementation Method 2
the cap having a weight greater than the weight of a body of water with the same volume of the cap
Implementation Method 3
roughness of the surface of the cap and/or the side wall where they are in contact with each other makes it possible to realize such a rate of seepage. The roughness provides for channels for water seepage
Implementation Method 4
the cap having a weight greater than the weight of a body of water with the same volume of the cap
Implementation Method 5
a stay defining a predefined offset between opposite sections of the central opening

AI summary
The invention relates to a plate-shaped structure for cultivating one or more plants. The plate-shaped structure may optionally collect moisture from the atmosphere and comprises a generally flat upper surface provided with a cavity for holding plant material. The cavity has a sidewall and a bottom portion. Further, the bottom portion includes an aperture traversing the plate-shaped structure. In use, the plate shaped structure can cover a reservoir or can be placed on the soil. The plate-shaped structure comprises a drain opening with a cap that is heavier than water and a covering cap so as to allow moisture to seep between the cap and the sidewall of the drain opening while minimizing evaporation.
