Solution Overview

Problem

Conventional roller trays require pouring paint or materials from their containers into a well, leading to mess and waste, and often necessitate separate trays for storage and use, which is inefficient.

Innovation Solution

A container with a built-in shelf and integrated pouring spout that allows for easy distribution and drainage of fluids, eliminating the need for a separate roller tray and minimizing waste, featuring a lid with a resealable additive hole for adding materials without removing it from the base member.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If paint is poured from container into a separate roller tray, then the paint can be applied to a roller, but this creates mess and waste

Engineering Contradiction:
Improveease of paint transferVSAvoidpaint waste
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

The patent combines the paint container and roller tray into a single integrated unit. The container includes an internal shelf that serves as the roller tray, eliminating the need for separate pouring operations and preventing paint spillage and waste that occurs when transferring paint between separate containers.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The roller tray shelf is nested within the paint container, with the shelf positioned inside the container body. This nesting arrangement allows the roller to be loaded with paint directly from the container without external pouring, solving the mess and waste problem while maintaining compact storage.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If a separate roller tray is used, then paint application is possible, but this requires purchasing and storing additional equipment

Engineering Contradiction:
Improvepaint application capabilityVSAvoidnumber of separate components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the paint container and roller tray into one unified device. The internal shelf structure provides the tray function while the container provides storage, eliminating the need for separate equipment and reducing the overall complexity of the paint application system.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated container-tray unit serves multiple functions: storing paint, acting as a mixing container for additives, serving as a roller loading tray, and providing a workspace for paint preparation. This multi-functionality eliminates the need for multiple separate tools and equipment.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If the lid is removed to add additives, then additives can be incorporated, but this risks accidental removal and loss of materials

Engineering Contradiction:
Improveadditive additionVSAvoidlid security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The lid is segmented with a separate additive hole that is distinct from the main opening. This segmentation allows additive incorporation through a small dedicated aperture while the main lid remains securely closed, preventing accidental removal and maintaining security while enabling easy additive addition.

Inventive Principle:
Principle #1Segmentation

4Ease of operation

If a resealable additive hole is incorporated into the lid, then additives can be added without removing the lid, but this adds complexity to the lid structure

Engineering Contradiction:
Improveadditive addition convenienceVSAvoidlid structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The lid is segmented with a separate additive hole that is distinct from the main opening. This segmentation allows additive incorporation through a small dedicated aperture while the main lid remains securely closed, preventing accidental removal and maintaining security while enabling easy additive addition.

Inventive Principle:
Principle #1Segmentation

AI summary

The present invention is directed toward a novel container system that is designed to hold and store liquids, such as for example, paints, stains, and various other coatings. The container system generally includes a base member, a shelf that is contained within the base member, and a lid. The shelf is provided with the base member and is designed to accept an application device, such as for example a paint roller. A lid is also provided with the container so that a fluid may be provided and stored as part of an all-inclusive delivery system.
