Hand Washing Basin Drain Adapter for Easier Installation and Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand washing stations, particularly those with integrated functions like water dispensing, soap dispensing, and hand drying, face challenges such as difficult installation, limited space for large components, and complex drain pipe connections that are hard to clean.
Innovation Solution
A hand washing station design featuring a basin assembly with a rear wall-mounted configuration, including a sloping front surface, a trough for drainage, and a drain adapter that connects to a drain pipe, allowing for efficient water disposal and improved cleaning access, along with integrated dispensers and dryers on a continuous shelf.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If integrated sinks with multiple functions are installed in public restrooms, then hand washing functionality is provided, but installation difficulties and servicing challenges occur
Solution Approach 1:
The sink is divided into modular components including the basin assembly, shelf assembly, and rear wall assembly that can be separately manufactured and assembled. The drain adapter is also a separate detachable component, allowing for easy replacement and maintenance without replacing the entire sink unit.
Solution Approach 2:
The drain adapter serves as an intermediary component between the basin and the drain pipe, providing a standardized connection interface that simplifies installation and maintenance. This intermediate component can be easily replaced or serviced without affecting the entire sink system.
2Quantity of substance
If large components such as large-capacity soap supply containers are installed, then soap dispensing capacity is improved, but sufficient installation space is not available
Solution Approach 1:
The design utilizes vertical space and rear wall area for component placement. The rear wall assembly provides mounting space for soap supply containers and other components, effectively using the third dimension (depth from the wall) rather than only horizontal surface area.
Solution Approach 2:
Components are arranged to fit within and around each other efficiently. The shelf assembly integrates with the basin assembly, and components are positioned to utilize available space within the overall sink structure, maximizing the use of limited installation area.
3Productivity
If drain pipe connections are configured in traditional sinks, then water drainage is achieved, but excessive space is required and cleaning becomes difficult
Solution Approach 1:
The drain adapter is extracted as a separate, accessible component from the integrated sink structure. It can be easily removed and replaced without disassembling the entire sink, allowing for simple maintenance and cleaning of the drain area.
Solution Approach 2:
Instead of having the drain connection embedded deep within the sink structure, the drain adapter is positioned to be accessible from the front and top, allowing easy access for cleaning and maintenance while still effectively draining water from the basin.

AI summary
A hand washing station includes a basin assembly having a rear configured for mounting to a wall surface and a front opposite the rear. The basin assembly includes a basin having a trough positioned proximate to the rear of the basin assembly and recessed from an adjacent surface of the basin located forward of the trough, with the trough having a front wall extending downward from the adjacent surface and a bottom wall extending rearward from the front wall. The basin assembly also includes a drain within the trough, formed by a slot extending through the front wall. A drain adapter is mounted on the trough below the basin and includes a passage in communication with the drain and extending through the drain adapter to an outlet for connection to a drain pipe, where the drain adapter receives water exiting the drain and outputs the water to the drain pipe.
