Solution Overview

Problem

Logistics systems face challenges in increasing throughput without high mechanical stress on conveyor components and in managing space requirements for parallel operation, which complicates the storage and retrieval of unit loads in high-bay racking.

Innovation Solution

A conveyor system that transports multiple unit loads side by side using a single conveying means, reducing mechanical load and increasing transport volume, combined with a storage and retrieval device featuring carriages that accommodate and release unit loads without the need for lifting mechanisms, optimizing storage and retrieval processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the speed of conveyor systems is increased to achieve higher throughput, then productivity increases, but the mechanical load on conveyor components greatly increases

Engineering Contradiction:
ImprovethroughputVSAvoidmechanical load on components
Core Design Contradiction:
ProductivityVSStrength

Solution Approach 1:

The conveyor system is divided into multiple parallel conveyor elements (first conveyor element, second conveyor element) that can operate simultaneously. Each conveyor element handles a portion of the unit loads, allowing the system to achieve higher overall throughput without requiring any single conveyor to operate at excessively high speeds that would create excessive mechanical stress.

Inventive Principle:
Principle #1Segmentation

2Productivity

If multiple identical components are used for parallel operation to increase capacity, then throughput increases, but space requirements and system complexity increase

Engineering Contradiction:
ImprovethroughputVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

Multiple conveyor elements are merged into a unified system with integrated control and coordinated operation. The first and second conveyor elements work together with the storage and retrieval device, sharing common infrastructure and control mechanisms, which reduces overall system complexity compared to completely separate parallel systems while still achieving increased throughput.

Inventive Principle:
Principle #5Merging (Combining)

3Productivity

If multiple identical components are used for parallel operation to increase capacity, then throughput increases, but space requirements increase

Engineering Contradiction:
ImprovethroughputVSAvoidspace requirement
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The system transitions from a single linear conveyor arrangement to a multi-dimensional layout where conveyor elements are arranged in parallel and can operate simultaneously. The first conveyor element and second conveyor element are positioned to handle different streams of unit loads, utilizing spatial arrangement to achieve parallel processing without requiring proportional increases in total facility space.

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