Solution Overview

Problem

Current packaging solutions for two-component or multi-component products used in painting and spraying are cumbersome, costly, prone to spillage, and require complex handling, with fragile flexible bags being sensitive to thermal variations and lacking modularity, leading to inefficiencies and quality issues during spraying.

Innovation Solution

A disposable assembly designed for packaging, preparation, and application on spray tools, featuring a container body with a side surface, bottom, and opening, including a mounting projection and hollow elements for separate component storage, which can be securely attached to spray tools and dissociated for disposal, allowing for mixing and efficient spraying.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Weight of moving object

If flexible plastic bags are used for packaging two-component products, then the packaging can be lightweight and easy to handle, but they are fragile, prone to punctures and tears, and sensitive to temperature fluctuations

Engineering Contradiction:
Improvepackaging weightVSAvoidpackaging integrity
Core Design Contradiction:
Weight of moving objectVSReliability

Solution Approach 1:

The patent changes the material parameter from flexible plastic to rigid material, transforming the packaging from lightweight but fragile to more durable and temperature-resistant. This parameter change resolves the contradiction by accepting increased weight in exchange for improved reliability and temperature stability.

Inventive Principle:
Principle #35Parameter changes

2Stability of the object's composition

If each component is individually packaged in separate containers, then the components can be stored separately to prevent premature mixing, but the packaging becomes bulky and costly, and multiple transfer operations are required

Engineering Contradiction:
Improvecomponent separationVSAvoidpackaging structure
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent merges multiple separate component containers into a single integrated packaging unit with internal compartments. Each component remains separately contained to prevent premature mixing, but the unified structure eliminates the need for multiple separate containers and transfer operations, reducing complexity and cost.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent uses a nested structure where individual component containers are placed within a larger outer packaging shell. This allows separate storage of components while consolidating them into a single manageable unit that reduces overall packaging bulk and simplifies handling.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Measurement precision

If manual mixing of components is performed by the operator, then the mixing process can be controlled, but it increases preparation time and risk of incorrect dosing

Engineering Contradiction:
Improvedosing accuracyVSAvoidpreparation time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent pre-measures and pre-packages exact dosages of each component into separate compartments during manufacturing. This preliminary action eliminates the need for operators to perform manual measuring and mixing, ensuring precise dosing while significantly reducing preparation time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The packaging design enables self-mixing through mechanical activation (such as shaking or inverting the container), allowing the components to mix automatically without operator intervention. This self-service approach ensures consistent mixing while freeing the operator from time-consuming manual mixing tasks.

Inventive Principle:
Principle #25Self-service

4Duration of action of stationary object

If partially emptied containers are stored for later use, then the remaining components can be preserved, but the components deteriorate in air and storage becomes cumbersome

Engineering Contradiction:
Improvecomponent shelf lifeVSAvoidair exposure
Core Design Contradiction:
Duration of action of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The patent designs the packaging as a disposable single-use unit. After the components are mixed and used, the entire container is discarded. This eliminates the problem of storing partially emptied containers, as the packaging is intended for one complete use cycle only, preventing air exposure and deterioration of remaining components.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The packaging includes separate sealed compartments for each component that remain isolated until use. This segmentation prevents air exposure to individual components during storage, extending their shelf life until the moment of mixing and use.

Inventive Principle:
Principle #1Segmentation

AI summary

The invention relates to a disposable assembly (1) having a closed body (5) used to contain a first component and comprising a side surface (6), a bottom (7), and an upper opening. The bottom (7) has a mounting projection (12) facing the interior of the body (5), to be inserted, such as to be sealingly fit, in the complementary shaping of the lower end (14) of a hollow lower tubular element (13) used to hold a second component (4), while the other end (15) thereof is closed by a sealing means (16). A seal (17) is sealingly mounted on the opening (8) of the body (5) by screwing, snap-fitting or nesting. The seal (17) and the sealing means (16), or the seal (17) and the hollow tubular element (13) can form one part. Said invention is of interest to producers of paints, varnishes, primers and other products to be sprayed by means of a gun, as well as to gun manufacturers.
