Solution Overview

Problem

Current machines for processing foam glass aggregate into usable sizes for construction materials excessively pulverize the material, resulting in significant waste as powder, with only about half of the input being usable, while wasting around 50% of the aggregate.

Innovation Solution

A foam glass aggregate slicing and reduction machine featuring a collection chute, rotating roller with knives, and a filtering bar that slices the aggregate into fragmented pieces of approximately ⅜ inch size with minimal powdery waste, utilizing a series of machines to achieve efficient size reduction and waste minimization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If current foam glass aggregate crushing machines are used to reduce aggregate size, then the aggregate is reduced to usable sizes, but the aggregate is excessively pulverized into powder with 50% waste

Engineering Contradiction:
Improveaggregate size controlVSAvoidfoam glass aggregate waste
Core Design Contradiction:
Manufacturing precisionVSLoss of substance

Solution Approach 1:

The aggregate reduction process is divided into multiple stages: primary reduction by fixed knives, secondary reduction by rotating roller knives, and final sizing by grid screen segmentation. This multi-stage approach allows progressive size reduction without excessive pulverization, maintaining aggregate integrity while achieving target sizes.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the machine perform different functions: the fixed knives provide initial coarse reduction, the rotating roller knives provide finer reduction, and the grid screen provides final size classification. Each component is optimized for its specific local function, preventing uniform over-crushing throughout the entire process.

Inventive Principle:
Principle #3Local quality

2Productivity

If aggressive crushing is used to reduce aggregate size quickly, then productivity increases, but manufacturing precision deteriorates with excessive pulverization

Engineering Contradiction:
Improveaggregate reduction speedVSAvoidaggregate fragment size control
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The crushing process is segmented into multiple passes through different knife stages and grid screens. This allows rapid size reduction in the first stage while subsequent stages refine the size control, achieving both high productivity and precise size specification without excessive pulverization.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fixed knives perform preliminary coarse reduction before the material reaches the rotating roller knives. This preliminary action removes large excess material quickly, allowing the subsequent stages to focus on precise size control, thereby maintaining both productivity and manufacturing precision.

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If single-stage crushing is used to simplify the machine, then device complexity decreases, but manufacturing precision worsens with powder generation

Engineering Contradiction:
Improvemachine structureVSAvoidaggregate size control
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The machine is divided into distinct functional segments: fixed knife assembly, rotating roller knife assembly, and grid screen assembly. Each segment performs a specific size reduction or classification function, allowing the system to achieve precise size control while maintaining relatively simple individual component designs that are easier to manufacture and maintain.

Inventive Principle:
Principle #1Segmentation

4Ease of operation

If conventional crushing machines are used, then ease of operation is maintained, but loss of substance increases to 50% waste

Engineering Contradiction:
Improvemachine operationVSAvoidfoam glass aggregate waste
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

The fixed knives perform preliminary size reduction before the material enters the main crushing zone. This preliminary action reduces the workload on subsequent stages, allowing the machine to operate more efficiently with lower energy input and reduced aggregate waste, while maintaining ease of operation through automated multi-stage processing.

Inventive Principle:
Principle #10Preliminary action
