Bath Seat Channel Layout for Unblocked Fluid Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bath chairs with drainage holes aligned with buttock cheeks can cause fluid pooling and discomfort due to the flat-bottomed design, which inhibits effective drainage and promotes the accumulation of bodily fluids.
Innovation Solution
A bath chair with a centrally disposed channel extending 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.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a flat-bottomed channel with drainage holes aligned with buttock cheeks is used, then the chair structure is simple, but fluid pools within the channel and does not drain effectively, causing discomfort
Solution Approach 1:
The channel is designed with a curved bottom surface instead of a flat bottom, creating a spherical or rounded profile that facilitates fluid flow toward the drainage holes. This curvature prevents fluid pooling by directing all accumulated fluid toward the drainage openings, thereby improving drainage effectiveness while maintaining manufacturing feasibility through standard molding techniques.
2Ease of operation
If drainage holes are aligned with buttock cheeks, then the drainage holes are positioned to capture bodily fluid, but the user's buttock cheeks block the drain holes, preventing fluid passage
Solution Approach 1:
The drainage system is segmented into multiple drainage holes distributed across the channel rather than relying on a single blocked opening. This segmentation ensures that even if some holes are partially obstructed by the user's body, other holes remain accessible and functional for draining bodily fluids.
Solution Approach 2:
The drainage holes are positioned at different locations and depths within the channel structure, creating a three-dimensional drainage network. This spatial distribution in multiple dimensions allows fluid to reach drainage holes from various paths, preventing complete blockage by the user's buttock cheeks.
3Reliability
If multiple channels with drainage holes are used, then drainage coverage is increased, but the number of flatter areas promotes undesired pooling of bodily fluids
Solution Approach 1:
The channel features a continuously curved bottom surface without flat areas, creating a spherical profile that directs fluid flow toward the drainage holes. This eliminates pooling zones that would otherwise form on flat surfaces, while the single integrated channel maintains adequate drainage coverage through its curved geometry and strategic hole placement.
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 enhances comfort by preventing fluid pooling and efficiently draining bodily fluids, making the chair suitable for prolonged use without discomfort.
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.
