Solution Overview

Problem

The existing fiber processing plants face limitations in throughput due to the capacity constraints of conveyor equipment and weighing scales, which restrict the number of bale openers that can be effectively used without significant modifications to the existing machinery.

Innovation Solution

The solution involves dividing bale openers into at least two opener groups, each with its own conveying device that transports the fiber mixture in different directions, allowing the mixtures to be combined before a processing device, such as a mixing chamber or card feed, without requiring extensive modifications to the existing conveyor belts or scales.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the number of bale openers is increased to increase throughput, then fiber material throughput is improved, but the conveying equipment capacity is exceeded and weighing scales cannot handle the volume

Engineering Contradiction:
Improvefiber material throughputVSAvoidfiber volume
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The system divides the fiber material flow into multiple partial streams by assigning different conveying devices to different opener groups. Each conveying device handles a separate fiber mixture from its assigned opener group, preventing any single conveying device or scale from being overloaded while maintaining high overall throughput

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The conveying devices are arranged to transport fiber mixtures in different directions relative to their associated opener groups, creating a multi-dimensional transport architecture. This spatial arrangement allows multiple conveying paths to coexist without interfering with each other's capacity, enabling the system to handle larger total volumes

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If multiple bale openers are placed side by side to increase throughput, then fiber material throughput is improved, but the conveying equipment cannot handle the total fiber volume without modifications

Engineering Contradiction:
ImprovethroughputVSAvoidconveying equipment modifications
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

Bale openers are divided into separate opener groups, each with its own conveying device. This segmentation allows existing conveying devices to be used in their original capacity without modification, as each device only needs to handle the fiber volume from its assigned opener group rather than the total volume from all openers

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple fiber mixtures from different opener groups are combined in a mixing chamber or carding feeder downstream. This merging point allows the system to aggregate the output from multiple segmented conveying paths, achieving high throughput while each individual conveying device operates within its original capacity limits

Inventive Principle:
Principle #5Merging (Combining)

3Productivity

If scales are used to weigh fiber material from multiple bale openers, then fiber material throughput is improved, but the scales cannot weigh very large quantities of fiber

Engineering Contradiction:
Improvefiber material throughputVSAvoidweighing capacity
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

Each opener group with its assigned conveying device has an associated scale that weighs only the fiber mixture from that specific opener group. This segmentation of the weighing function allows existing scales with limited capacity to accurately measure smaller, manageable quantities without being overwhelmed by the total fiber volume from all openers

Inventive Principle:
Principle #1Segmentation
