Dome-Shaped Plantpot Base With Profile Struts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plant pots for commercial horticulture, designed to be thin-walled for cost savings, often sag and buckle due to filling or root pressure, compromising drainage and stability, especially when filled with substrate or inserting trellises, leading to instability and potential waterlogging issues.
Innovation Solution
The integration of profile struts, either as solid or hollow profiles, to stiffen the dome-shaped base, converting bending forces into tensile forces that are absorbed by the pot's peripheral walls, enhancing stability and preventing buckling while maintaining water drainage capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If the plant pot bottom is made thin-walled for cost savings, then material expenditure is reduced, but the base becomes susceptible to buckling and pushing through under load
Solution Approach 1:
The base is divided into a dome-shaped area and a flat peripheral area separated by profile struts. This segmentation allows the dome area to be thin-walled for material savings while the profile struts provide structural reinforcement to prevent buckling under load.
Solution Approach 2:
The base has different structural qualities in different areas: the dome-shaped area uses thin-walled construction for material efficiency, while the profile struts and flat peripheral area provide localized reinforcement where structural strength is needed to prevent buckling.
2Volume of stationary object
If the dome shape is kept relatively flat to minimize pot space loss, then volume is reduced, but the base becomes vulnerable to buckling when vigorously filled
Solution Approach 1:
The base is segmented into a dome-shaped area and a flat peripheral area with profile struts between them. This allows the majority of the base to remain flat for volume efficiency while the profile struts provide localized reinforcement to prevent buckling during vigorous filling.
Solution Approach 2:
The base structure varies by location: the dome-shaped area provides minimal arching for volume efficiency, while the profile struts and flat peripheral area provide localized structural reinforcement where buckling resistance is critical during filling operations.
3Strength
If profile struts are added to stiffen the dome shape, then buckling resistance is improved, but device complexity increases
Solution Approach 1:
The profile struts are merged with the dome-shaped base in a single molded construction. This integration combines the reinforcement function with the base structure itself, avoiding the need for separate attachment components and reducing overall device complexity.
Solution Approach 2:
The profile struts serve multiple functions: they reinforce the dome shape to prevent buckling, separate the dome-shaped and flat peripheral areas, and are integrated into the single-mold construction. This multi-functionality reduces the need for additional components.
4Reliability
If the bottom provides openings for drainage, then water drainage capability is improved, but the base becomes more vulnerable to structural failure under pressure
Solution Approach 1:
The base has different structural qualities in different areas: the dome-shaped area with profile struts provides structural reinforcement to prevent buckling, while the flat peripheral area contains drainage openings. This local differentiation allows drainage functionality without compromising overall structural integrity.

AI summary
A plastic plantpot (1), comprising a predominantly vertically oriented wall (2) and a predominantly horizontally oriented base (5) which is connected at its edge to the wall (2) and which is upwardly curved in the form of a dome (13, 21) at least in an inner portion, is designed, with the aim of securing the base region against pushing-through and denting of the thinnest possible thin-walled material, in such a way that the dome (13, 21) is reinforced by profiled braces (14, 22) which extend as underprops from a central region (15) of the dome (13, 21) to at least peripheral regions (9) of the dome (13, 21).
