Solution Overview

Problem

Current paint production systems face issues with colorant adherence to container lids during mixing, leading to incorrect dosage and color, and require large warehouses for storing various base combinations, necessitating inefficient storage solutions.

Innovation Solution

An automatic high-speed line with sequential dosing units and mixing units that ensure precise dosing and mixing of bases and colorants within retail containers, incorporating integrity control and lid application to prevent colorant adherence and optimize storage needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If colorants are dosed into containers with lids before mixing, then the dosing process can be simplified, but colorant adheres to the lid inner face and is not properly mixed with the base

Engineering Contradiction:

Improvedosing process simplicityVSAvoidcolorant dosage accuracy

Core Design Contradiction:

Ease of manufactureVSManufacturing precision

Solution Approach 1:

The lid is removed before the dosing operation, and then re-applied after dosing. This preliminary action of removing the lid prevents colorant adhesion to the lid surface, ensuring accurate dosing while maintaining container closure integrity for subsequent mixing and storage.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If multiple types of bases are stored in a large warehouse, then various paint combinations can be produced, but warehouse space requirements increase significantly

Engineering Contradiction:

Improvepaint combination varietyVSAvoidwarehouse space

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

A single container type is designed to hold different base formulations by changing the base loading parameters. The universal container design eliminates the need for multiple specialized container types, reducing storage space while maintaining versatility in producing different paint combinations.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system dynamically adjusts base dosing parameters and container handling procedures based on the required paint formulation. This dynamic adaptability allows one container type to serve multiple base formulations, eliminating the need for static specialized storage for each base type.

Inventive Principle:

Principle #15Dynamics

3Stability of the object's composition

If containers are agitated to mix colorants with bases, then final paint color is achieved, but colorant may adhere to lid and not mix properly

Engineering Contradiction:

Improvepaint color uniformityVSAvoidcolorant mixing accuracy

Core Design Contradiction:

Stability of the object's compositionVSManufacturing precision

Solution Approach 1:

The lid is removed before dosing to prevent colorant adhesion during mixing, then re-applied after dosing is complete. This ensures that during agitation, the colorant remains in the base liquid rather than adhering to the lid, achieving uniform mixing and accurate coloration.

Inventive Principle:

Principle #10Preliminary action

AI summary

An automatic line for producing paints and the like wherein a dispensing of the bases and colorants is programmed so as to dispense in an order a first base, a dose of colorant and a second base inside a retail container, so that before mixing, the colorant is confined between two bases and there is no risk of part of the colorant adhering to an inner face of the lid without participating in the mixing.
