Solution Overview

Problem

Conveyor devices with chain conveyors face challenges in smoothly transitioning materials over the gap between adjacent conveyors without disruption, especially when the material is small compared to the gap size, and require adjustable roller modules that can operate at synchronized speeds and be driven from different points.

Innovation Solution

The solution involves a roller module with rotatable carrier rollers that engage with conveyor rollers to ensure synchronized speed and a toothed belt system allowing drive connection from either adjacent chain conveyor, enabling adjustable width and continued operation during blockages, with a frictional or form-fitting engagement mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conveyor rollers are used to bridge the conveying ditch between two chain conveyors, then material transfer is enabled, but the rollers may run at different speeds causing disruption

Engineering Contradiction:
Improvematerial transfer continuityVSAvoidroller speed synchronization
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

An intermediary drive mechanism (toothed belt connecting both chain conveyors to the roller module) is introduced to coordinate the rotation of multiple conveyor rollers, ensuring they all run at the same peripheral speed and eliminating speed synchronization issues

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The drive functions of both adjacent chain conveyors are merged through a common toothed belt system that simultaneously engages both conveyors and the roller module, creating a unified drive system that ensures synchronized operation

Inventive Principle:
Principle #5Merging (Combining)

2Ease of manufacture

If the roller module width is made fixed, then manufacturing is simplified, but adaptability to different conveyor configurations is reduced

Engineering Contradiction:
Improveroller module productionVSAvoidmodule width adjustment
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The roller module is segmented into multiple independent conveyor rollers that can be selectively assembled in different quantities and arrangements, allowing the module width to be adapted to different conveyor configurations while using standardized roller components

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The roller module design allows dynamic reconfiguration of the number and arrangement of conveyor rollers, enabling the same basic module design to adapt to varying width requirements without requiring completely different manufacturing processes

Inventive Principle:
Principle #15Dynamics

3Device complexity

If the roller module is driven from only one chain conveyor, then the drive system is simplified, but the system cannot accommodate drives from different points

Engineering Contradiction:
Improvedrive system structureVSAvoiddrive connection flexibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The toothed belt drive system is designed with universal engagement capabilities that allow it to be driven from either of the two adjacent chain conveyors, making the same roller module adaptable to different installation scenarios and drive locations

Inventive Principle:
Principle #6Universality (Multi-functionality)
