Pigment Concentrate Dosing Container Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing pigment-containing products face challenges in reproducibility of color shades and efficiency, leading to high costs and waste due to inaccurate pigment quantity requests and settling issues during mixing.
Innovation Solution
The method involves producing a pigment concentrate in a dosing container with a pigment-free base material of higher density to prevent settling, allowing for precise mixing and addition to base materials using conventional mixing devices, eliminating the need for pre-filled base colors and ensuring complete mixing without residue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pigment concentrates are filled into individual dosing containers and mixed on site, then the processor can produce pigment-containing products according to color specifications, but the reproducibility of color shades deteriorates due to incomplete mixing and pigment settling
Solution Approach 1:
The pigment mixture is prepared in advance in a dosing container before being added to the base material. This preliminary mixing ensures that the pigment is uniformly distributed and completely mixed, eliminating the problem of incomplete mixing and pigment settling that occurs when mixing on-site. The dosing container is specifically designed to facilitate complete mixing of the pigment concentrate with the base material before application.
2Productivity
If the processor orders pigment-containing products based on estimated quantities, then production can be initiated, but material loss increases due to either insufficient quantity (requiring reordering and remixing) or excessive quantity (resulting in waste)
Solution Approach 1:
The dosing container provides precise measurement feedback on the exact amount of pigment-containing product that can be produced with the available base material. This allows the processor to order the exact quantity needed, preventing both insufficient quantity (which would require reordering and remixing) and excessive quantity (which would result in waste). The feedback mechanism is achieved through the controlled dosing process that measures and dispenses precise amounts.
Solution Approach 2:
The method changes the parameter of pigment concentration by using a dosing container that precisely controls the amount of pigment concentrate added to the base material. This parameter control ensures that the correct quantity of pigment-containing product is produced, eliminating material loss due to overproduction or the need for remixing after reordering.
3Ease of manufacture
If basic paints or base colors are filled into dosing containers, then pigment mixing can be simplified, but the ability to produce custom color shades deteriorates due to limitations in pigment mixture flexibility
Solution Approach 1:
The dosing container is designed to receive and mix multiple different pigment-containing base materials separately before combining them. This segmentation allows for flexible creation of custom color shades by controlling the amount of each pigment type added, while maintaining ease of manufacture through the automated dosing and mixing process. The container can accommodate various pigment concentrates and base materials, providing both simplicity and versatility.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach ensures reliable and cost-effective production of consistent color shades by preventing pigment settling and ensuring complete mixing, reducing waste and time losses associated with incorrect pigment quantities.
Implementation Method 1
the pigment-free base material in the process according to the invention has a greater density than the pigment-containing base materials, so that a heterogeneous mixture is formed when the dosing container is charged
Implementation Method 2
This can prevent the pigments from settling in the bottom area of the dosing container and no longer fully participating in the subsequent mixing process
