Solution Overview

Problem

Material handling vehicles in warehouses face challenges in transferring learned routes between vehicles with different geometries, as existing systems do not effectively account for geometric disparities, leading to inefficiencies in route adaptation and operation.

Innovation Solution

A method involving a warehouse management system with a transfer matrix that processes operation information from a first vehicle to compensate for geometric differences between vehicles, allowing the processed information to be transferred and executed by a second vehicle, enabling autonomous operation along similar routes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If route information is transferred directly between material handling vehicles with different geometries, then the transfer process is simple, but the route accuracy and navigation precision deteriorate

Engineering Contradiction:
Improveroute transfer processVSAvoidroute accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The system transforms route information by applying geometric transformation parameters that account for differences in vehicle dimensions, wheelbase, and turning radius. The transfer matrix modifies coordinates, angles, and path parameters based on the specific geometric characteristics of both source and target vehicles, ensuring accurate route adaptation without requiring complex manual reprogramming.

Inventive Principle:

2Measurement precision

If a transfer matrix is used to process operation information for geometric compensation, then route accuracy and navigation precision improve, but the system complexity increases

Engineering Contradiction:
Improveroute accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The transfer matrix serves as an intermediary computational layer between the source vehicle's route data and the target vehicle's navigation system. It automatically performs geometric compensation calculations, transforming high-level route commands into vehicle-specific navigation instructions without requiring complex modifications to either the data collection or execution systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The transfer matrix is designed as a universal solution that can handle multiple types of geometric disparities between different vehicle models. A single matrix structure accommodates various vehicle configurations by adjusting transformation parameters, eliminating the need for multiple specialized processing systems for different vehicle pairs.

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

3Reliability

If operation information is collected from manual vehicles, then the collected data reflects real operational patterns, but the automation level decreases

Engineering Contradiction:

Solution Approach 1:

The system performs preliminary route learning during manual operation phases, collecting and storing operational patterns before transitioning to autonomous mode. This preliminary data collection during manual operation ensures that the autonomous vehicle inherits proven effective routing strategies while maintaining high automation levels during actual execution.

Inventive Principle:
Principle #10Preliminary action
