Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydroponic cultivation systems require complex mechanisms for transporting seedbeds due to their configuration, which increases costs and complexity.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If horizontal seedbeds are used with expansion mechanism, then spaces between seedbeds can be widened, but the transport mechanism becomes complicated requiring multiple screws
Solution Approach 1:
The patent inverts the conventional horizontal seedbed configuration to a vertical hanging configuration. Instead of expanding horizontal seedbeds perpendicular to movement, vertical seedbeds expand in the horizontal plane during transport. This inversion allows a single screw mechanism to control both transport and space widening, eliminating the need for multiple screws and complex mechanisms.
2Ease of operation
If horizontal seedbeds are transported, then the transport mechanism must support the weight of seedbeds, but this increases the complexity and cost of the transport mechanism
Solution Approach 1:
The patent transitions from horizontal seedbed transport to vertical hanging transport. By changing the orientation from horizontal to vertical, the transport mechanism only needs to handle lateral movement rather than supporting full weight during transport. The hanging configuration allows gravity to naturally support the seedbed weight, simplifying the transport mechanism structure.
3Adaptability or versatility
If multiple screws are used for seedbed expansion, then space between seedbeds can be increased, but the system complexity and cost increase
Solution Approach 1:
The patent makes a single screw mechanism perform multiple functions: it simultaneously transports the vertical seedbeds horizontally and controls the widening of spaces between them. This multi-functionality eliminates the need for separate expansion mechanisms and multiple screws, reducing system complexity and manufacturing cost while maintaining adaptability.
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 system simplifies the transport mechanism, reduces costs, and enhances efficiency by allowing smooth seedbed movement and efficient planting, while maintaining seedbed positioning and preventing damage during transport.
Implementation Method 1
The transport mechanism includes one screw formed to have a pitch that is increased in a stepwise manner toward the predetermined horizontal direction
Implementation Method 2
Each of the seedbed or the transport mechanism may include a sliding mechanism that slides the seedbed in the predetermined horizontal direction at a time of transporting the seedbed

AI summary
[Object] To provide a hydroponic cultivation system that is capable of transporting a seedbed with a simple mechanism and has excellent durability. [Solving Means] A hydroponic cultivation system includes a plurality of seedbeds, a hanging part, and a transport mechanism. A plurality of seedlings of a plant to be cultivated are transplanted to side surfaces of the plurality of seedbeds. The hanging part hangs each of the plurality of seedbeds while the plurality of seedbeds are arranged in a predetermined horizontal direction from a planting side of the seedlings to a harvesting side of the seedlings. The transport mechanism transports the plurality of seedbeds in the predetermined horizontal direction while widening spaces between the seedbeds in the predetermined horizontal direction in a stepwise or continuous manner.
