Solution Overview

Problem

Existing methods for selecting and preparing a sample of colored paint, varnish, or lacquer are inefficient, costly, and wasteful due to difficulties in precisely dosing minimal quantities of pigments, leading to repeated production cycles and excess material waste.

Innovation Solution

A kit and method using pre-dosed units of powdered color pigments, which can be easily mixed with a base paint, varnish, or lacquer to create a sample of the desired color, allowing precise dosage and reduced waste.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If powdered pigments are used to color paint, varnish or lacquer, then color precision can be improved, but dosing precision deteriorates because minimum quantities of pigments are difficult to dose accurately

Engineering Contradiction:
Improvecolor precisionVSAvoiddosing precision
Core Design Contradiction:
Manufacturing precisionVSMeasurement precision

Solution Approach 1:

The patent divides the pigment dosing problem into discrete segments by using pre-dosed capsules, each containing a specific amount of pigment. This segmentation allows for precise dosing through simple counting rather than measurement, resolving the contradiction between color precision and dosing precision.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies preliminary action by pre-dosing the pigment into capsules before the actual painting process. The pigments are portioned out in advance into precise, measurable units that can be easily added to the paint, eliminating the need for precise measurement during the actual dosing process.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If a greater quantity of base paint, varnish or lacquer is used for dosing pigments, then dosing error can be reduced, but material waste increases

Engineering Contradiction:
Improvedosing errorVSAvoidmaterial waste
Core Design Contradiction:
Manufacturing precisionVSLoss of substance

Solution Approach 1:

The patent segments the pigment into small, pre-measured capsules that can be accurately dosed without requiring large quantities of base paint. This allows for precise pigment dosing in minimal amounts of paint, reducing both dosing error and material waste.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent changes the parameter of pigment concentration by using highly concentrated pigment in small capsules rather than diluted pigment in large quantities of paint. This parameter change allows for accurate dosing with minimal paint volume, reducing material waste while maintaining precision.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If liquid diluted pigments are used for coloring, then ease of mixing is improved, but dosing precision deteriorates because minimum quantities are difficult to dose accurately

Engineering Contradiction:
Improveease of mixingVSAvoiddosing precision
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent changes the physical state parameter of the pigment from liquid to solid capsule form. This parameter change maintains ease of mixing (the capsule dissolves or disperses in the paint) while dramatically improving dosing precision through simple counting of discrete units.

Inventive Principle:
Principle #35Parameter changes

Applied Scientific Principles

AI summary

The present invention refers to a kit, a method, and a colouring unit, for preparing a coloured sample of paint, lacquer or varnish for the selection, by the user, of a desired colour of a paint, lacquer or varnish to be applied to a wall or to a support. The kit and the method according to the present invention allow users to produce a reduced quantity of sample of paint, lacquer or varnish thanks to the possibility of employing specifically conceived pre- dosed colouring units, and thanks to the possibility of having available precise indications about the type and the quantity of colouring units to be added to the base paint, varnish or lacquer to obtain a determined colour, also as a function of different quantities of the base paint, lacquer or varnish.
