Conical Funnel Sink Liner with Grated Filter for Paint Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cleaning paint brushes and rollers in sinks often damages the sink due to paint residue and dried paint, which can stain or clog drains, and may require harmful solvents or vigorous scrubbing, and poses risks to garbage disposals.
Innovation Solution
A conical funnel with a grated filter is used to fit into the sink drain, accompanied by a tarp that covers the basin and attaches to the countertop, creating a protective barrier to contain paint and prevent damage, while the filter catches larger paint pieces for easy disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If paint brushes and rollers are cleaned in a traditional sink, then cleaning effectiveness is improved, but the sink basin and drain are damaged by paint residue and dried paint
Solution Approach 1:
The patent introduces a sink liner as an intermediary barrier between the paint cleaning process and the sink basin. The liner is placed inside the sink to receive paint residue and dried paint, preventing direct contact with the sink surface. This mediator allows effective paint cleaning while protecting the sink from staining and damage, resolving the contradiction between cleaning effectiveness and sink protection.
2Ease of operation
If hydrocarbon solvents are used to remove paint residue, then paint removal capability is improved, but harmful chemical effects on sink materials increase
Solution Approach 1:
The sink liner serves as a protective intermediary that isolates the sink basin from direct exposure to hydrocarbon solvents and paint residue. This allows users to employ strong solvents for effective paint removal without the chemicals directly contacting and damaging sensitive sink materials like natural stone, thereby resolving the contradiction between paint removal capability and chemical damage prevention.
3Ease of operation
If steel wool or vigorous scrubbing is used to remove paint, then paint removal capability is improved, but mechanical damage to sink finish increases
Solution Approach 1:
The sink liner acts as a sacrificial intermediary surface that absorbs the mechanical impact of steel wool and vigorous scrubbing. Paint can be aggressively removed from the liner without damaging the underlying sink finish, thus resolving the contradiction between paint removal capability and mechanical damage prevention.
4Productivity
If paint is allowed to drain into garbage disposal, then drainage function is maintained, but damage to garbage disposal increases
Solution Approach 1:
The patent extracts harmful paint clumps and dried paint pieces from the drainage stream using a filter component integrated into the sink liner system. This filtration mechanism removes problematic paint material before it can reach and damage the garbage disposal, while still allowing normal water drainage to proceed, thus resolving the contradiction between maintaining drainage function and preventing disposal damage.

AI summary
A tarp or sheet attached to the wide end of a conical funnel designed to fit snuggly in a drain to provide a protective barrier for a sink when cleaning paint brushes and roller covers. The conical funnel may contain a grated filter inside to catch paint clots that would otherwise clog the sink or damage the garbage disposal.
