Solution Overview

Problem

Existing storage systems for storage bins are limited in the number of simultaneously operating remotely operated vehicles due to the cross-sectional coverage of each vehicle corresponding to two storage columns, restricting operational efficiency.

Innovation Solution

The design includes a remotely operated vehicle with dual sets of rolling mechanisms (X and Y directions) equipped with electric motors and advanced motor control electronics, allowing independent movement and operation of multiple vehicles within the same cross-sectional area, utilizing wheels and belts for efficient navigation and bin handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If each vehicle covers a cross section corresponding to two storage columns, then the vehicle structure is simple and stable, but the maximum number of simultaneously operating vehicles is limited

Engineering Contradiction:
Improvenumber of simultaneously operating vehiclesVSAvoidcross-sectional coverage of vehicle
Core Design Contradiction:
ProductivityVSArea of moving object

Solution Approach 1:

The vehicle's rolling means are divided into two independent sets: a first rolling set for movement along a first direction and a second rolling set for movement along a second direction perpendicular to the first direction. This segmentation allows the vehicle to navigate more efficiently through the storage system without requiring excessive lateral space, thereby increasing the number of simultaneously operating vehicles.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention introduces bidirectional rolling capability by adding a second rolling set that operates in a direction perpendicular to the first rolling set. This dimensional addition enables vehicles to access storage columns from multiple directions, reducing the cross-sectional area each vehicle needs to cover and allowing denser vehicle deployment in the storage system.

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

2Productivity

If the vehicle uses dual sets of rolling means with independent driving, then the number of simultaneously operating vehicles increases, but the device complexity increases

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The vehicle's rolling means are divided into two independent sets: a first rolling set for movement along a first direction and a second rolling set for movement along a second direction perpendicular to the first direction. This segmentation allows the vehicle to navigate more efficiently through the storage system without requiring excessive lateral space, thereby increasing the number of simultaneously operating vehicles.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each rolling set is equipped with its own driving means, allowing the vehicle to independently control movement in both the first and second directions. This multi-functionality enables the vehicle to perform complex navigation tasks using a modular architecture, where each rolling set can be controlled autonomously to achieve efficient path planning and collision avoidance, thereby supporting higher vehicle density without proportionally increasing overall system complexity.

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