Portable wash basin assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drywall tools, such as drywall compound applicators, require frequent washing but often lack access to running water or utility sinks on job sites, making effective cleaning challenging.
Innovation Solution
A portable wash basin assembly with a basin featuring multiple recesses along its upper edge to secure tools during cleaning, along with adjustable legs and a drain system for efficient water use, allowing tools to be washed and dried on-site.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a portable wash basin is used without running water access, then tool cleaning can be performed on-site, but water must be manually carried and managed
Solution Approach 1:
The wash basin is designed as a self-contained portable unit separate from fixed plumbing infrastructure. The basin, stand, and drain components are segmented to allow manual transport and deployment at various job site locations without requiring connection to running water supplies.
Solution Approach 2:
The portable basin assembly acts as an intermediary between the tool cleaning need and the water source. Water is manually carried in containers (such as gallon jugs) to the basin, which serves as a temporary holding and washing station, eliminating the need for direct running water access.
2Adaptability or versatility
If tools are washed in a portable basin, then cleaning can occur anywhere, but water drainage becomes challenging
Solution Approach 1:
The drainage system is segmented into modular components including a removable drain assembly, extensible drain tube, and collection container. This segmentation allows the drainage function to be adapted to various ground conditions and locations without requiring complex fixed infrastructure.
Solution Approach 2:
The drain tube is designed to be extensible and adjustable in length and positioning. The drain assembly can be dynamically configured to reach appropriate drainage points or collection containers based on the specific job site terrain and water volume, providing flexible drainage without complex fixed systems.
3Adaptability or versatility
If the wash basin is designed to accommodate different tool sizes, then versatility is improved, but basin size and portability are compromised
Solution Approach 1:
The basin interior features localized recesses and contoured areas specifically designed to accommodate different tool geometries. These localized structural variations allow tools of various sizes and shapes to be securely positioned without requiring a uniformly larger basin, thus maintaining portability while providing tool size adaptability.
4Reliability
If the basin includes multiple recesses for tool positioning, then tool security during washing is improved, but manufacturing complexity increases
Solution Approach 1:
The recesses are designed as discrete, modular features that can be independently formed during manufacturing. Each recess serves a specific tool positioning function and can be created using standard molding or forming techniques, making the manufacturing process manageable despite the multiple features.

AI summary
A portable wash basin assembly for cleaning a tool includes a wash basin having a base and at least one sidewall that extends upward from the base to an upper edge. The wash basin is configured to receive a liquid for cleaning the tool. A plurality of legs are coupled to the wash basin and are adjustable between a use position and a non-use position. A drain is located in the basin and configured to direct the liquid within the basin to a location below the basin. The wash basin is supported upon a frame. The portable wash basin assembly has a first height when the plurality of legs are in the use position and a second height, less than the first height, when the plurality of legs are in the non-use position. The legs are pivotably coupled to the frame between the use position and the non-use position.
