Paint Tray Disposable Liner System with Bumper Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional paint trays are difficult to clean due to ridged designs, and existing disposable liners are costly, poorly fitting, and often reused instead of disposed of, leading to inefficiencies and contamination risks.
Innovation Solution
A paint tray system with a disposable liner that consists of a flexible sheet held in place by a separable liner holding frame and bumper system, allowing easy application, secure fit, and simple removal for disposal, along with an optional cover to prevent paint drying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pre-formed molded plastic liners are used, then paint tray cleanup is facilitated, but the liners do not fit well and get bent and twisted
Solution Approach 1:
The patent uses a flexible sheet material for the liner that can be easily placed and conform to the paint tray interior. This flexible material prevents bending and twisting issues while maintaining proper fit and function during paint application and cleanup processes.
Solution Approach 2:
The patent divides the liner system into separate components: a flexible sheet liner and a rigid frame structure. This segmentation allows the flexible liner to be easily handled and positioned without the structural constraints that cause bending in pre-formed molded liners.
2Ease of operation
If pre-formed molded liners are used, then paint tray cleanup is facilitated, but they are costly to produce and use
Solution Approach 1:
The flexible sheet material can be manufactured more cost-effectively than rigid molded liners. This material choice reduces production costs while maintaining the cleanup facilitation benefit, making the liner economically viable for single-use applications.
Solution Approach 2:
The patent creates a disposable liner system using inexpensive flexible sheet material that can be easily disposed of after single use. This approach eliminates the need for expensive molded liners while achieving the same cleanup facilitation purpose.
3Object-affected harmful factors
If plastic wrap or foil is used to cover the paint tray, then cross-contamination is prevented, but it is time-consuming to set up and messy to dispose of
Solution Approach 1:
The flexible sheet liner provides a pre-formed barrier that prevents cross-contamination more effectively than loose plastic wrap or foil. The structured design eliminates the time-consuming setup and messy disposal issues associated with traditional wrapping methods.
Solution Approach 2:
The flexible sheet liner acts as an intermediary barrier between the paint tray and external contaminants. This structured intermediate layer provides better containment and easier handling compared to loose plastic wrap or foil, reducing setup time and disposal mess.
4Reliability
If adhesive-lined liners are used, then the liner is held in place during use, but they are expensive and awkward to fit into the paint tray
Solution Approach 1:
The flexible sheet liner can be easily positioned and adjusted within the paint tray without adhesive, eliminating the awkward fitting process. The flexibility allows it to conform to the tray interior while maintaining proper position during use.
Solution Approach 2:
The patent uses simple flexible sheet material without expensive adhesive linings, making the liner both cheaper to produce and easier to apply. The disposable nature allows for simple placement and removal without complex adhesive mechanisms.

AI summary
A paint tray with disposable liner system generally comprises two components, a paint tray base, and a liner holding frame which cooperatively engages with the paint tray base to securely hold a paint tray liner therebetween so as to position the paint tray liner overtop of the interior surface of the paint tray base. The paint tray base has a bumper extending around the periphery of the paint tray base from the exterior surface of its walls. The liner holding frame is sized to slidingly fit onto the paint tray base and engage the bumper, wherein engagement of the liner holding frame with the bumper securely fixes a paint tray liner in place therebetween. A cover can optionally be included in the system that includes a cover holding frame sized to fit on top of the paint tray base above the liner holding frame, wherein the cover holding frame comprises a channel to receive a top end of a corresponding wall of the paint tray base to securely fix the paint tray cover in place therebetween.
