Solution Overview

Problem

Conveyor belt systems face contamination and damage to belt ends prior to splicing, leading to structurally compromised splices and prolonged plant shut-downs during maintenance.

Innovation Solution

An encapsulated belt end containment system that protects belt ends from environmental contaminants and damage by encapsulating the exposed cables in containment bags, allowing for controlled preparation and storage before splicing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If belt ends are prepared and stored before splicing, then splice time during maintenance is reduced, but belt ends are exposed to contamination and damage

Engineering Contradiction:
Improvesplice time during maintenanceVSAvoidcontamination and damage to belt ends
Core Design Contradiction:
Loss of timeVSObject-affected harmful factors

Solution Approach 1:

The belt end is prepared in advance by removing rubber material and organizing cables into groups before the actual splicing operation. This preliminary preparation reduces the time required during maintenance shutdowns while the containment bag protects the prepared state from contamination and damage during storage.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

A containment bag made of flexible material is used to enclose the prepared belt end and its cable groups. This flexible shell protects the belt end from environmental contaminants and physical damage during storage and transport, while allowing easy deployment when needed for splicing.

Inventive Principle:
Principle #30Flexible shells and thin films

2Ease of manufacture

If belt ends are exposed for preparation, then splicing can be performed, but the exposed cables are vulnerable to environmental contaminants

Engineering Contradiction:
Improvesplicing operationVSAvoidenvironmental contaminants
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The containment bag acts as a flexible shell that encloses the exposed cables and belt end during storage and transport. It provides a physical barrier against environmental contaminants such as dust, moisture, and debris, while still allowing the splicing operation to proceed when the bag is opened at the splicing location.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The containment bag serves as an intermediary between the prepared belt end and the environmental contaminants. It mediates the protection of the vulnerable exposed cables during storage and transport, enabling the belt end to be prepared in advance without direct exposure to harmful environmental factors.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Manufacturing precision

If multiple cable groups are organized in the belt end, then splicing quality is improved, but the complexity of encapsulation increases

Engineering Contradiction:
Improvesplicing qualityVSAvoidencapsulation process
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The cables in the belt end are divided into multiple separate groups, with each group contained within its own containment bag. This segmentation allows for organized and precise splicing of individual cable groups while simplifying the encapsulation process by treating each group as a separate, manageable unit rather than a complex tangled mass.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple containment bags, each containing a cable group, are nested within a larger outer containment bag. This nested structure protects multiple cable groups simultaneously while maintaining individual organization, balancing the need for splicing precision with manageable encapsulation complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)
