Shower Curtain Surface Appendages to Prevent Mold Buildup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Shower curtains and liners often accumulate water, leading to the growth of foreign bodies like bacteria, mold, and mildew due to surface tension, which is exacerbated in humid environments and makes cleaning cumbersome.
Innovation Solution
A shower curtain with appendages extending outwardly from its surface, designed to prevent contact with adjacent surfaces, promoting airflow and drying, thereby inhibiting the growth of foreign bodies. The appendages can vary in size, shape, and geometry to optimize effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the shower curtain is allowed to contact the adjacent surface (tub/shower basin), then it provides better coverage and water containment, but water accumulates between the curtain and surface leading to foreign body growth
Solution Approach 1:
The patent applies dimensionality change by adding appendages that extend outwardly from the curtain surface in a third dimension (perpendicular to the curtain plane). This creates an air gap between the curtain and the tub surface, allowing airflow to reach areas that would otherwise be in direct contact, thus preventing foreign body accumulation while maintaining water containment coverage
2Object-affected harmful factors
If spacers are attached to the tub rim to hold the curtain away from the rim, then foreign body growth is reduced, but the spacers intrude into shower space and make cleaning more cumbersome
Solution Approach 1:
The patent extracts the spacing function from separate spacers attached to the tub rim and integrates it directly into the curtain structure through outwardly extending appendages. This eliminates the need for separate spacer components that intrude into shower space, while still achieving the goal of preventing curtain-surface contact and foreign body growth
Solution Approach 2:
The patent merges the spacing function with the curtain structure itself by forming appendages as integral parts of the curtain material. This combines the water containment function of the curtain with the spacing function, eliminating the need for separate spacer components and simplifying the overall system
3Ease of operation
If the curtain is maintained close to the outer edge of the enclosure to maximize movement space, then occupant room to move about is increased, but the curtain contacts the inner surface of the tub allowing water and foreign bodies to accumulate
Solution Approach 1:
The patent uses dimensionality change by adding outwardly extending appendages that create an air gap in the third dimension (perpendicular to the curtain), allowing the curtain to be positioned close to the tub edge for maximum occupant space while preventing surface contact and foreign body accumulation through the created airflow path
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 solution effectively reduces the accumulation and growth of foreign bodies on the curtain surface, requiring less frequent cleaning, reducing allergen exposure, and extending the replacement cycle, thus promoting economic, environmental, and social sustainability.
Implementation Method 1
appendages on the surface of the curtain that increases airflow and reduces the entrapment of water between the curtain and an adjacent surface
Implementation Method 2
Surface tension of the water can keep the shower curtain adhered to the adjacent surface
Data Source
AI summary
It is well known that plastic shower curtains can develop mildew and/or mold where the curtain adheres to another surface and remains moist, such as the edge of a bathtub. A shower curtain with at least a portion of the surface being non-smooth is disclosed. In some embodiments, appendages extend outwardly from the surface of the curtain. The appendages prevent the surface of the curtain from adhering to another surface via surface tension of water. Furthermore, the appendages create an air gap that enables air to flow freely between the curtain and its adjacent surface. The appendages also reduce the surface area of the curtain in contact with the adjacent surface.
