Solution Overview

Problem

Existing technologies for managing separable vehicles are inefficient in retrieving a vehicle body unit laid at a specific place, requiring significant time and effort from users, especially when the unit is located at temporary operation sites like event venues.

Innovation Solution

An information processing apparatus and method that employs an autonomous chassis unit, capable of decoupling and recoupling from a vehicle body unit, to autonomously retrieve the vehicle body unit from a specific place upon user request, selecting the most suitable chassis unit based on location and availability, and controlling its travel and coupling operations to transport the unit to a designated destination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If a user manually retrieves a vehicle body unit from a specific place, then the retrieval operation can be completed, but it requires significant time and effort from the user

Engineering Contradiction:
Improveretrieval timeVSAvoiduser effort
Core Design Contradiction:
Loss of timeVSEase of operation

Solution Approach 1:

The chassis unit autonomously performs the retrieval operation without human intervention. The control device automatically selects an available chassis unit, sends retrieval commands, and coordinates the coupling/decoupling operations, allowing the system to serve itself rather than requiring user manual operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical retrieval operations with an autonomous control system that uses electronic commands and automated coupling/decoupling mechanisms. The control device substitutes human physical effort with automated decision-making and execution systems.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If multiple chassis units are managed in the system, then retrieval flexibility is improved, but the complexity of selecting and managing available chassis units increases

Engineering Contradiction:
Improveretrieval flexibilityVSAvoidchassis management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control device receives operational status information from multiple chassis units and uses this feedback to automatically determine which chassis unit is available for retrieval operations. This closed-loop information flow enables automated selection without requiring complex manual management protocols.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The control device autonomously manages the fleet of chassis units by automatically selecting appropriate units based on their operational status. The system self-regulates the allocation and assignment of chassis units without requiring external coordination complexity.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If autonomous retrieval is implemented, then user effort is reduced, but the system requires intelligent selection and coordination of chassis units

Engineering Contradiction:
Improveuser effortVSAvoidchassis selection automation
Core Design Contradiction:
Ease of operationVSExtent of automation

Solution Approach 1:

The control device uses real-time feedback on chassis unit operational status to make intelligent selection decisions. This automated feedback mechanism enables the system to autonomously determine which chassis unit should perform the retrieval operation without human intervention while maintaining operational reliability.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The autonomous retrieval system performs the complete selection and execution process without user involvement. The control device independently manages chassis unit selection, command issuance, and operation coordination, fully automating what would otherwise require user effort.

Inventive Principle:
Principle #25Self-service

AI summary

An information processing apparatus disclosed has a controller configured to execute the processing of accepting a request for retrieving a target vehicle body unit that is laid at a specific place, selecting a chassis unit for retrieval from among chassis units in the state separated from any vehicle body unit, the chassis unit for retrieval being a chassis unit to be used to retrieve the target vehicle body unit, and sending a retrieval command to the chassis unit for retrieval, the retrieval command being a command to retrieve the target vehicle body unit.
