Non-Uniform Flexural Rigidity Water Transport Line
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water transport lines for potted plants often suffer from buckling and kinking issues due to uniform flexural rigidity, leading to unreliable water delivery and an unsightly appearance.
Innovation Solution
A tubular flexible casing with non-uniform band-shaped casing walls of varying flexural rigidity, where the first casing wall has a higher material-specific flexural rigidity, achieved through differences in wall thickness and material composition, particularly with a central strip of higher modulus material, reduces buckling tendency and enhances aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If uniform flexural rigidity is used in the casing walls, then the casing is simple to manufacture, but the casing tends to buckle and kink during water transport
Solution Approach 1:
The patent applies local quality by creating non-uniform flexural rigidity distribution in the casing walls. The first casing wall is designed with higher flexural rigidity than the second casing wall, allowing different regions of the casing to have different mechanical properties. This local differentiation prevents buckling and kinking while maintaining overall structural simplicity and manufacturing ease.
2Reliability
If the first casing wall has higher flexural rigidity, then the buckling tendency is reduced, but the material composition and wall thickness must be varied
Solution Approach 1:
The patent employs composite materials by combining different material compositions in the first and second casing walls. The first casing wall uses materials with higher flexural rigidity (such as thicker walls or materials with higher modulus of elasticity) compared to the second casing wall. This composite approach achieves the desired differential flexural rigidity while remaining manufacturable through conventional extrusion or molding processes.
3Shape
If the casing walls have different flexural rigidity, then the aesthetic appearance is improved, but the manufacturing process becomes more complex
Solution Approach 1:
The patent applies local quality by creating non-uniform flexural rigidity distribution in the casing walls. The first casing wall is designed with higher flexural rigidity than the second casing wall, allowing different regions of the casing to have different mechanical properties. This local differentiation prevents buckling and kinking while maintaining overall structural simplicity and manufacturing ease.

Implementation Method 1
Water transport lines made of fibrous material have long been known for watering potted plants, which transport water from a reservoir counter to gravity to a higher planting substrate in a planter by the action of the capillary effect

AI summary
The invention relates to a potted plant watering device and a water transporting line (WL) which is used in said watering device, said transporting line comprising a fibrous material (FB) which makes use of capillary action and comprising a watertight casing (HU) which surrounds the fibrous material in a tubular manner. The fibrous material (FB) and the casing (HU) are formed in a flat manner in the shape of a strip, and the tubular casing (HU) walls (W1, W2) which are formed in a flat manner in the shape of a strip, which lie opposite each other, and which enclose the fibrous material (FB) between each other are designed with different flexural rigidities. The different flexural rigidities are preferably achieved by forming a second casing wall (W2) with a constant wall thickness (DW) from a homogenous material and by increasing the flexural rigidity of the first casing wall (W1) by means of a central strip (MS) consisting of a second material with a greater wall thickness and/or a higher Shore hardness.
