Solution Overview
Problem
Conventional hydroponic culture support devices made of polystyrene are fragile, non-recyclable, and inefficient in material usage, leading to waste and increased costs, while existing polymeric solutions are not optimally configured for seed planting and root development, and lack reusability and stacking capabilities.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If polystyrene panels are used for hydroponic cultivation, then the panels provide buoyancy and support structure, but the panels are structurally fragile and break during handling
Solution Approach 1:
The patent uses polyethylene, a polymeric material that combines buoyancy with high structural strength and flexibility. This material choice resolves the contradiction by providing both the required structural integrity to prevent breakage during handling and the buoyancy necessary for hydroponic cultivation, unlike fragile polystyrene panels.
2Quantity of substance
If polystyrene panels are used, then the panels are inexpensive and provide buoyancy, but they absorb culture liquid and allow bacteria and mold to proliferate
Solution Approach 1:
The patent changes the material parameter from polystyrene to polyethylene, which has different surface properties that do not absorb culture liquid. This parameter change eliminates the harmful effect of bacterial and mold proliferation while maintaining buoyancy and structural integrity, and the material remains cost-effective.
3Strength
If conventional polystyrene panels are used, then the panels provide support structure, but they are not recyclable and increase disposal costs
Solution Approach 1:
The patent employs polyethylene material that is recyclable, allowing the panels to be recovered and reused after cultivation cycles. This resolves the contradiction by enabling both structural support functionality and environmental sustainability through recycling, eliminating disposal costs associated with non-recyclable polystyrene.
4Volume of moving object
If V-shaped seats with large volume are provided in the panel, then the seats accommodate substrate and seedlings, but excessive inert material is wasted
Solution Approach 1:
The patent optimizes the seat geometry parameters to match the actual volume requirements for substrate and seedling development. By adjusting the seat dimensions and shape, the design provides sufficient space for cultivation while minimizing excess volume that would waste inert materials like perlite, thereby reducing material costs.
5Shape
If V-shaped seats with undercuts are provided, then the seats are formed by convergent arched walls, but the configuration is not optimal for mechanical operations
Solution Approach 1:
The patent employs asymmetric seat geometry with optimized wall angles and profiles that facilitate mechanical operations. The seat shape is designed to allow easy filling with inert material, efficient seed positioning, and simple plant extraction, while maintaining structural integrity. This asymmetric design improves operational ease compared to conventional symmetric V-shaped seats.

AI summary
The present invention relates to a support device (1) for hydroponic cultures formed of a panel made of polymeric material comprising a plurality of separate and distinct hollow tubular elements (2) arranged side-by-side and spaced apart in parallel so as to create a plurality of seats (20) suitable to contain an inert substrate for hydroponic cultures, each defined between two adjacent tubular elements (2) and extending between an upper opening (21) and a lower opening (22). In particular, said tubular elements (2) each have a shaped cross-section, defined by a curved top portion (2A) and a pair of flat and inclined side walls (2B) extending symmetrically with respect to a vertical axis (X-X) and diverging towards the outside, such that said seats (20) have a substantially "funnel-shaped" section.
