Solution Overview

Problem

Existing material processing machines face challenges in achieving uniform application of colorants to reduced waste materials, as direct spraying methods often result in non-uniform coverage due to obstruction by particulates and the potential for some material to exit the reducing chamber before colorant application.

Innovation Solution

A colorizer system is integrated into the material processing machine, positioning a manifold near the reducing chamber to direct pressurized colorant towards the rotor and processing tool assemblies, ensuring uniform coating during the reduction process, with the colorant applied contemporaneously with material reduction and subsequent discharge.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If colorant is sprayed directly onto the surfaces of reduced wood chips, then colorant application is simplified, but uniform coverage is poor due to particulate obstruction and material exiting before application

Engineering Contradiction:

Improvecolorant application simplicityVSAvoidcolorant coverage uniformity

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The colorizer system is positioned to apply colorant to the waste material before or during the reduction process, rather than after. The manifold with nozzles directs colorant into the reducing chamber where it coats the material as it is being processed, ensuring uniform coverage before the material exits the chamber.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary system (the colorizer with manifold and nozzles) that delivers colorant through the reducing chamber environment. The colorant is applied via nozzles positioned to coat material during reduction, acting as a mediator between the colorant source and the final colored product.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If colorant is applied after material reduction, then the reducing system operates independently, but some material may exit the reducing chamber before receiving colorant

Engineering Contradiction:

Improvesystem integration levelVSAvoidcomplete colorant application

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The colorizer system is merged with the reducing system by positioning the manifold and nozzles within or adjacent to the reducing chamber. This integration ensures that colorant application and material reduction occur simultaneously in the same space, guaranteeing that all material passing through the chamber receives colorant treatment.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The system maintains continuous colorant application throughout the material reduction process. The colorant is continuously delivered via the manifold and nozzles as material moves through the reducing chamber, ensuring uninterrupted coating action without gaps where material might escape uncolored.

Inventive Principle:

Principle #20Continuity of useful action

Function Achieved in This Case

This approach ensures that nearly all reduced material is uniformly colored, minimizing waste and improving aesthetics, while also preventing colorant application directly to the outlet zone, thus enhancing the efficiency and uniformity of the colorization process.

AI summary

A material processing machine for material reducing operations. The material processing machine comprises an infeed system, a reducing system, and a discharge system. The reducing system comprises a rotor having processing tools to reduce the material within a reducing chamber. A colorizer system directs colorant from a colorant source towards the material reducing system within an outlet zone. The colorant colorizes the material being reduced within an inlet zone. The reduced material may be discharged through one or more screens within the outlet zone such that negligible colorant is applied directly to the reduced material. The material reducing operations may comprise a two-stage reducing operation in which the colorizer system is inoperable for the first stage and operable for the second stage. The screens may be selectively interchangeable between stages to incrementally reduce the material to provide substantially uniform colorizing and material size.
