Solution Overview

Problem

In logistics handling systems, the operation of traveling means on a rail is limited and logistics throughput decreases when parts related to backup power supply are handled for maintenance, repair, or replacement, leading to unstable operation of power supply devices and OHT units.

Innovation Solution

A logistics handling system with a traveling rail and power supply device that allows multiple traveling units with different operation modes to operate based on power supply state conditions, including a main unit powered externally and a sub-unit powered internally, enabling continuous and stable operation even during handling of backup parts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If backup parts of power supply device are handled for maintenance, repair, or replacement, then power supply reliability is improved, but traveling means operation is limited and logistics throughput decreases

Engineering Contradiction:
Improvepower supply reliabilityVSAvoidlogistics throughput
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The traveling means is divided into a main body unit and a separate power supply unit. The power supply unit can be detached and handled independently without affecting the main body unit's operation on the rail, allowing maintenance of backup parts while continuing logistics operations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A power supply device serves as an intermediary between external power sources and traveling units. It provides non-contact power supply to traveling units, enabling them to operate independently of the physical connection to power supply backup parts, thus allowing maintenance without stopping operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple traveling units with different operation modes are operated, then adaptability to power supply conditions is improved, but system complexity increases

Engineering Contradiction:
Improveadaptability to power supply conditionsVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The traveling units are designed with dynamic operation modes that can adapt to different power supply conditions. The units can switch between contact-based and non-contact-based power supply modes, and between different operation states, allowing flexible adaptation without requiring completely different system configurations.

Inventive Principle:
Principle #15Dynamics
