Solution Overview

Problem

Automatic traveling vehicles require significant storage space and labor for storage, as they are typically stored in a linear fashion, which is inefficient and labor-intensive.

Innovation Solution

The automatic traveling vehicle is equipped with electronic control units that enable it to take a storage posture by superposing or lining up with other vehicles, using its automatic traveling function to reduce storage space, with features like rotatable top plates and frames that allow for compact positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If automatic traveling vehicles are stored in a linear fashion, then the storage method is simple, but the storage space required is large and labor for storage is high

Engineering Contradiction:
Improvesimplicity of storage methodVSAvoidstorage space
Core Design Contradiction:
Ease of manufactureVSArea of stationary object

Solution Approach 1:

The patent applies dimensionality change by transitioning from linear (1D) storage to three-dimensional (3D) storage. Vehicles are stored in superposed states where multiple vehicles are stacked vertically, utilizing the vertical dimension to reduce the horizontal storage footprint. The electronic control units coordinate to position vehicles in stacked configurations, effectively converting a 1D storage problem into a 3D space utilization solution.

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

Solution Approach 2:

The patent implements nesting by placing one vehicle inside or upon another vehicle in a superposed storage state. Vehicles are configured to store other vehicles within their structural boundaries, similar to nested dolls. The frame structures and top plates are designed to accommodate stacked configurations, allowing multiple vehicles to occupy the same horizontal footprint by nesting them vertically.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of manufacture

If automatic traveling vehicles are stored in a linear fashion, then the storage arrangement is simple, but the labor for storing vehicles is high

Engineering Contradiction:
Improvesimplicity of storage arrangementVSAvoidoperator labor efficiency
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The patent implements self-service by enabling vehicles to perform their own storage operations through automatic traveling functions. The electronic control units coordinate vehicles to autonomously navigate to storage positions and assume superposed states without operator intervention. This transforms manual storage operations into self-service automated processes, dramatically reducing labor requirements while maintaining storage organization.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent applies preliminary action by having vehicles autonomously position themselves in storage configurations before operator involvement is needed. The electronic control units pre-coordinate vehicle movements to achieve optimal storage arrangements, allowing vehicles to self-organize into superposed states in advance, thereby eliminating the need for operators to manually arrange vehicles during storage operations.

Inventive Principle:
Principle #10Preliminary action

3Area of stationary object

If vehicles are configured with rotatable top plates and frames for superposed storage, then storage space is reduced, but the vehicle structure becomes more complex

Engineering Contradiction:
Improvestorage spaceVSAvoidvehicle structure
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent applies universality by designing the top plate and frame structures to serve multiple functions: they provide structural support for vehicle operation and simultaneously enable superposed storage configurations. The rotatable top plate serves both as a functional vehicle component and as a mechanism for achieving vertical stacking. This multi-functionality reduces the need for separate storage-specific components, thereby limiting the increase in overall structural complexity while achieving compact storage.

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

AI summary

An automatic traveling vehicle includes a vehicle structure including a first top plate, and an electronic control unit. The electronic control unit is configured to execute a storage mode when a storage execution condition is satisfied. The storage mode includes a storage posture formation process of causing the vehicle to automatically travel so as to take a predetermined storage posture together with a counterpart automatic traveling vehicle. In the storage posture, the vehicle is in a superposition state in which the vehicle overlaps with the counterpart vehicle in a plan view, or a parallel state in which the vehicle is lined up with the counterpart vehicle while the first top plate and a second top plate of the counterpart vehicle are standing and facing each other so as to be parallel to or substantially parallel to a vertical direction.
