Solution Overview

Problem

Current technologies lack a systematic approach for managing and delivering a large number of mobility vehicles, such as golf carts, within a specific region, particularly in terms of warehousing and distributing their usage effectively.

Innovation Solution

An autonomous driving mobile service robot warehousing and delivery system that utilizes line parts, robot bodies, and a server to systematically store and deliver robot bodies by calculating and comparing delivery times, allowing sequential delivery from the line part with the smallest number of delivery times, thereby optimizing usage and extending the lifespan of components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If robot bodies are delivered without systematic management, then delivery operations can be performed, but usage rate distribution becomes uneven and component lifespan decreases

Engineering Contradiction:
Improvedelivery efficiencyVSAvoidusage rate distribution
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system implements a feedback mechanism where the server continuously receives delivery time information from counting parts, compares delivery times across different line parts, and adjusts delivery sequences accordingly. This closed-loop control ensures that line parts with fewer deliveries are prioritized, maintaining balanced usage rates and extending component lifespan while achieving systematic delivery management.

Inventive Principle:
Principle #23Feedback

2Speed

If robot bodies are delivered from all line parts simultaneously, then delivery speed increases, but usage rate distribution becomes uneven

Engineering Contradiction:
Improvedelivery speedVSAvoidusage rate distribution
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The delivery system dynamically adjusts the delivery sequence based on real-time delivery time information. Instead of static simultaneous delivery from all line parts, the server dynamically determines which line part should deliver next by comparing their delivery times, creating a flexible and adaptive delivery schedule that balances speed with usage rate distribution.

Inventive Principle:
Principle #15Dynamics

3Reliability

If a systematic delivery management system is implemented, then usage rate distribution improves, but system complexity increases

Engineering Contradiction:
Improveusage rate distributionVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The server acts as an intermediary that centralizes the complex delivery management functions. Instead of distributing complexity across multiple control units, the server consolidates the logic for receiving delivery time information, comparing delivery times, and determining delivery sequences. This intermediary approach manages system complexity while achieving balanced usage rate distribution.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The present invention relates to an autonomous driving mobile service robot warehousing and delivery system that is capable of systematically storing and delivering a plurality of robot bodies from line parts by means of a server and comparing the number of delivery times of the robot bodies by line part to allow the robot bodies to be delivered sequentially from the line part having the smallest number of delivery times, thereby distributing the usage rate of the robot bodies disposed by line part.
