Solution Overview

Problem

Existing systems for transporting products using vehicles, such as delivery robots, face challenges in minimizing the time required for the vehicle to move to the start location after an order is completed, leading to increased waiting times.

Innovation Solution

An information processing device that acquires the status of an order and executes movement control to suppress the increase in movement distance from the vehicle's location to the start location, by controlling the vehicle's movement based on the order status before it is completed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the vehicle moves away from the start location before order completion, then the vehicle can be positioned for future tasks, but the required time to move back to the start location increases

Engineering Contradiction:
Improvevehicle utilization efficiencyVSAvoidwaiting time for transport start
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system performs preliminary movement control by monitoring order status and directing the vehicle to move toward the start location during the order processing phase, before the order is completed. This preliminary action ensures the vehicle is already positioned or near the start location when transport is needed, reducing the required time to move back and suppressing increases in movement distance.

Inventive Principle:
Principle #10Preliminary action

2Loss of time

If the vehicle remains stationary at the start location waiting for order completion, then the required time to move to the start location is minimized, but the vehicle cannot perform other useful tasks

Engineering Contradiction:
Improverequired time to move to start locationVSAvoidvehicle task completion rate
Core Design Contradiction:
Loss of timeVSProductivity

Solution Approach 1:

The system implements dynamic movement control that adapts the vehicle's behavior based on real-time order status. Instead of a fixed stationary position or unrestricted movement, the vehicle dynamically adjusts its movement toward the start location according to the order processing stage, enabling it to remain productive while ensuring timely positioning for transport tasks.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system uses feedback from order status monitoring to control vehicle movement. By continuously acquiring order status information and adjusting movement control accordingly, the system ensures the vehicle moves appropriately toward the start location only when necessary, balancing positioning requirements with productive task execution.

Inventive Principle:
Principle #23Feedback

AI summary

An information processing device includes at least one memory storing program code and at least one processor. The program code includes acquisition code configured to cause the at least one processor to acquire a status of an order. The program code also includes control code configured to cause the at least one processor to execute movement control according to the acquired status when the acquired status is a status before transition to a completion status, the movement control being control over a vehicle caused to transport a target of the order and suppressing an increase in movement distance from a location of the vehicle to a start location at which the transport is started, the completion status being a state in which the order is completed.
