Solution Overview

Problem

The complexity of overhead conveyor systems in distribution centers makes it difficult to detect and predict failures in carriers and functional units, leading to potential downtime and increased operational costs.

Innovation Solution

A carrier testing station equipped with monitoring units that can detect various characteristic values of carriers and functional units, allowing for real-time data collection and analysis to predict maintenance needs and prevent failures, thereby reducing downtime and costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If overhead conveyor systems use a large number of components to perform distribution functions, then the system's functionality and capacity are improved, but the complexity of the system increases making it difficult to detect and predict failures

Engineering Contradiction:
Improvedistribution capacityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the monitoring function by equipping individual carriers with monitoring units that independently detect and report the status of specific components (rollers, magnets, couplings) along the conveyor path. This segmentation allows the complex system to be monitored through multiple simple, distributed sensing points rather than requiring a single complex monitoring system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces carriers as intermediary monitoring platforms that travel along the conveyor system. These carriers carry monitoring units that act as intermediaries between the conveyor components and the central control system, collecting data from rollers, magnets, and couplings as the carrier passes by and transmitting status information without requiring direct connection to each component.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If monitoring units are installed to detect carrier characteristics, then failure detection capability is improved, but the device complexity and cost increase

Engineering Contradiction:
Improvefailure detection capabilityVSAvoidmonitoring system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The monitoring system uses the carriers themselves as the monitoring platform. Each carrier is equipped with a monitoring unit that automatically detects and reports the status of conveyor components during normal operation. The system serves itself by utilizing the existing carrier infrastructure for monitoring purposes, eliminating the need for separate fixed monitoring stations at each component location.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The carriers serve dual functions: they transport goods through the distribution center and simultaneously act as mobile monitoring platforms. The monitoring units on the carriers perform multiple detection tasks including roller rotation status, magnet presence, coupling integrity, and carrier identification, making the carrier system universally functional for both transport and diagnostics.

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

3Reliability

If continuous monitoring of all conveyor components is implemented, then reliability is improved, but energy consumption and operational costs increase

Engineering Contradiction:
Improvesystem reliabilityVSAvoidmonitoring energy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The monitoring system operates periodically rather than continuously. As carriers pass by specific conveyor components (rollers, magnets, couplings), the monitoring units automatically detect and record the status of these components. This periodic monitoring during normal carrier movement provides comprehensive system surveillance without requiring continuous energy-intensive monitoring of all components simultaneously.

Inventive Principle:
Principle #19Periodic action
