Bath Seat Drainage Channel Layout to Prevent Fluid Pooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bath chairs are uncomfortable for prolonged use due to fluid pooling and inadequate drainage, as flat-bottomed channels and drainage hole configurations hinder efficient fluid removal, leading to discomfort and potential skin contact with pooled water.
Innovation Solution
A bath chair with a centrally disposed channel between drainage holes, featuring enlarged rounded ends and a connecting u-shaped portion that directs fluid to the drainage holes, ensuring efficient drainage and reducing fluid contact with the user's skin, while maintaining a comfortable seating surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a flat-bottomed channel is used for drainage, then the channel structure is simple, but fluid pools within the channel and does not drain effectively
Solution Approach 1:
The channel is designed with a curved bottom surface that slopes downward toward the drainage hole, replacing the flat-bottomed design. This curvature facilitates fluid flow by preventing pooling and directing water toward the drainage opening, thereby improving drainage efficiency while maintaining structural simplicity
Solution Approach 2:
The channel features a localized curved drainage region with varying slope angles - steeper near the drainage hole and gentler toward the rear. This localized quality variation optimizes fluid flow dynamics in the critical drainage area without complicating the overall channel structure
2Productivity
If drainage holes are positioned to align with buttock cheeks, then drainage coverage is maximized, but the user's buttock cheeks block the drain holes and inhibit fluid passage
Solution Approach 1:
The drainage hole is positioned asymmetrically within the channel structure, specifically located at the forward end of the curved channel rather than centered under the seating area. This asymmetric placement ensures the hole remains accessible to fluid flow while avoiding direct alignment with the user's buttock cheeks that would block drainage
Solution Approach 2:
The curved channel acts as an intermediary structure that collects fluid from the seating surface and transports it to the drainage hole. This mediator approach allows drainage to occur indirectly, bypassing the need for direct alignment between drainage holes and body contact areas
3Productivity
If multiple channels and holes are added to improve drainage, then drainage capability increases, but the chair becomes less comfortable to sit upon
Solution Approach 1:
The drainage function is segmented into distinct components: a dedicated curved channel for fluid collection and transport, and a specifically positioned drainage hole for discharge. This segmentation achieves effective drainage through a single well-designed pathway rather than multiple channels, preserving seating comfort
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 design effectively drains fluids, preventing pooling and discomfort, making the chair more comfortable for extended use and suitable for users with incontinence issues or those experiencing fluid leakage during bathing.
Implementation Method 1
Fluid entering into the channel is directed to the drainage holes and thereby drains from the seat

AI summary
The present invention relates to a bath seat. The bath seat has a top and a pair of centrally disposed and spaced-apart drainage holes in communication with the top. The top of the seat includes a channel extending between the drainage holes. The channel has an enlarged first end, an enlarged second end and a connecting portion connecting the ends of the channel together. Fluid entering into the channel is directed to the drainage holes and thereby drains from the seat.
