Solution Overview

Problem

Existing logistics systems using autonomous robots do not effectively plan package delivery when destinations are dispersed across multiple floors of a building, leading to inefficient and potentially unsafe delivery processes.

Innovation Solution

A logistics system that includes processors configured to perform a priority determination process to identify the most efficient order for delivering packages across multiple floors based on factors such as congestion levels and specific target presence, and a logistics robot control process to execute the delivery in the determined order.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If packages are delivered to multiple floors without planning, then delivery operations can be performed, but delivery efficiency and safety are reduced due to congestion and unoptimized routes

Engineering Contradiction:
Improvedelivery efficiencyVSAvoiddelivery safety
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system performs preliminary determination of delivery priority for each floor before the logistics robot begins delivery operations. The management server analyzes delivery destinations across multiple floors and establishes a priority order in advance, allowing the robot to follow an optimized route that prevents congestion and ensures safe delivery operations.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If delivery destinations are dispersed across multiple floors, then more delivery locations can be served, but delivery complexity and time consumption increase

Engineering Contradiction:
Improvedelivery location coverageVSAvoiddelivery time consumption
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system dynamically determines delivery priority based on the specific distribution of delivery destinations across multiple floors. The management server analyzes the actual delivery locations and adjusts the priority order accordingly, enabling the logistics robot to efficiently navigate through floors with deliveries in an optimized sequence, thereby reducing time consumption while maintaining adaptability to various delivery scenarios.

AI summary

A logistics system provides a logistics service utilizing a logistics robot that delivers packages by autonomous traveling. The logistics system includes one or more processors. When delivery destinations of the packages are dispersedly located on a plurality of floors of a building, the one or more processors execute a priority determination process that determines priority among the plurality of floors. Then, the one or more processors execute a logistics robot control process that controls the logistics robot so as to deliver the packages to the plurality of floors in an order of the priority.
