Solution Overview

Problem

Existing automatic movement devices in delivery systems face inefficiencies in moving articles, particularly in terms of stability and efficiency of movement.

Innovation Solution

The device incorporates a vehicle body with two or more loading sections, a drive section for traveling wheels, and a control section to manage the loading and movement of conveyance objects, enhancing the efficiency of article movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a single loading section is provided, then the device structure is simple, but the movement efficiency of articles is insufficient

Engineering Contradiction:
Improvemovement efficiency of articlesVSAvoidloading section configuration
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The loading section is divided into multiple independent loading units (first loading section, second loading section, etc.), each capable of independently loading conveyance objects. This segmentation allows parallel operation of multiple loading points, thereby improving article movement efficiency without requiring a complete redesign of the entire loading system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple loading sections are provided on the same vehicle body, allowing the device to handle multiple conveyance objects simultaneously or sequentially. This multi-functionality enables the automatic movement device to serve multiple purposes and increase overall productivity without proportionally increasing device complexity.

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

2Quantity of substance

If multiple loading sections are provided, then more conveyance objects can be moved, but the device structure becomes more complex

Engineering Contradiction:
Improvenumber of conveyance objectsVSAvoidvehicle body structure
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

Multiple loading sections are integrated onto a single vehicle body structure, sharing common support frameworks, control systems, and power sources. This merging approach allows the device to handle multiple conveyance objects simultaneously while avoiding the complexity of having separate independent devices for each loading point.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

Loading sections are arranged in different spatial dimensions (e.g., front and rear positions, different heights) on the vehicle body. This dimensional arrangement allows multiple loading operations to occur simultaneously in different spatial zones, increasing the quantity of conveyance objects handled without significantly increasing structural complexity.

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