Solution Overview

Problem

Traditional paint containing devices are unstable and inefficient due to their large upper opening and limited depth, leading to paint spillage and the need for frequent refilling, causing discomfort and fatigue during use, especially when working on ladders.

Innovation Solution

A paint containing device with a first tray of larger upper opening and lesser depth connected to a second tray through a conduit, allowing paint to be transferred seamlessly without spillage, featuring an inclined surface for excess paint removal and handles for comfortable handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the tray has a large upper opening and limited depth, then the roller or brush can be comfortably impregnated with paint, but the paint becomes unstable and spills during handling

Engineering Contradiction:
Improvecomfort of roller impregnationVSAvoidstability of paint in tray
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The paint containing device is divided into two separate trays: a first tray with a large upper opening for roller impregnation and a second tray with a smaller upper opening for stable paint storage. This segmentation allows each tray to be optimized for its specific function, resolving the contradiction between ease of operation and stability.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the tray has limited depth, then the device is easy to handle, but the paint quantity is insufficient requiring frequent refilling

Engineering Contradiction:
Improveease of device handlingVSAvoidpaint quantity in tray
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The device uses two trays with different depth characteristics. The first tray has limited depth for easy handling and access, while the second tray can be deeper to hold larger paint quantity. The segmentation allows the system to provide sufficient paint capacity without compromising the ease of handling the primary working tray.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A conduit connects the two trays, acting as an intermediary that allows paint to be transferred from the second tray to the first tray. This mediator enables refilling without requiring the operator to leave the working position, thus maintaining ease of operation while increasing total paint quantity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If new paint is continually poured into the tray, then the painting work can continue, but time is lost and operator fatigue increases

Engineering Contradiction:
Improvecontinuity of painting workVSAvoidtime for refilling paint
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The second tray is prepared in advance with additional paint, serving as a pre-prepared reserve. When the first tray needs refilling, paint is already available in the second tray and can be transferred immediately through the conduit, eliminating the need for the operator to repeatedly leave and return for refilling.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The device enables self-service refilling through the conduit connection between trays. The system can be refilled by simply tilting it to allow gravity-driven paint flow from the second tray to the first tray, without requiring external intervention or time-consuming manual pouring operations.

Inventive Principle:
Principle #25Self-service

AI summary

The paint containing device (1) comprises a first tray (2) and an inclined surface (3) along which a roller can be passed in order to be squeezed to eliminate the excess paint. It also comprises a second tray (4) connected to the first tray (2) such that, when the paint is low in the first tray (2), it can be supplemented by taking it from the second tray (4).
