Solution Overview

Problem

In conventional logistics robot delivery systems, when the number of second vehicles is limited, delivery to users can be delayed, deteriorating the convenience of the recipient.

Innovation Solution

An information processing device estimates the time of package delivery completion by a logistics robot based on information about undelivered packages at an intermediate delivery point and the robot's delivery capability, and outputs this estimation to a user's terminal device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the number of logistics robots is limited, then the device complexity is reduced, but the delivery speed and user convenience deteriorate

Engineering Contradiction:
Improvenumber of logistics robotsVSAvoiddelivery speed
Core Design Contradiction:
Device complexityVSSpeed

Solution Approach 1:

The system performs preliminary actions by calculating and notifying users of estimated delivery times before actual delivery occurs. This allows users to plan their availability in advance, reducing waiting time and improving delivery efficiency without requiring additional robots.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by providing users with real-time information about package status and estimated delivery times through terminal devices. This enables users to make informed decisions about when to be available for receipt, optimizing the delivery process with limited robotic resources.

Inventive Principle:
Principle #23Feedback

2Device complexity

If the number of logistics robots is limited, then the device complexity is reduced, but the delivery time and user convenience deteriorate

Engineering Contradiction:
Improvenumber of logistics robotsVSAvoiddelivery time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The system calculates estimated delivery times in advance based on current queue status and robot availability, notifying users before delivery occurs. This preliminary information allows users to prepare, reducing actual delivery time and minimizing time loss without requiring additional robots.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Users receive continuous feedback about package status and timing through terminal devices, enabling them to optimize their schedules. This feedback mechanism reduces overall delivery time by coordinating user availability with robot delivery schedules, compensating for limited robotic resources.

Inventive Principle:
Principle #23Feedback

3Device complexity

If delivery status information is not provided to users, then the device complexity is reduced, but the user convenience deteriorates

Engineering Contradiction:
Improveinformation processing capabilityVSAvoiduser convenience
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The system provides users with feedback about package status, location, and estimated delivery times through terminal devices. This information feedback enables users to plan their availability, improving convenience without significantly increasing system complexity.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The information processing device acts as an intermediary between the logistics robots and users, translating complex delivery status data into user-friendly notifications. This mediator provides valuable information to users while keeping the overall system architecture relatively simple.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The information processing device includes a control unit that manages a logistics robot that delivers a package from an intermediate delivery point to a living place of each of a plurality of users. The control unit estimates the time at which the logistics robot completes the delivery of the first package to the first user based on the information on the undelivered package existing at the intermediate delivery point at the time at which the first package arrives at the intermediate delivery point and the delivery capability of the logistics robot. The control unit outputs the estimated time to the terminal device of the first user.
