Solution Overview

Problem

Existing automatic entry-exit systems for autonomous parking services are insufficient in reducing congestion at platforms, as simply proposing a change in exit time does not effectively mitigate high congestion levels.

Innovation Solution

The system includes a congestion degree determination unit and an alternative solution proposal unit that suggests using a less congested platform or proposing carpooling when high congestion is detected, allowing vehicles to enter and exit through autonomous driving.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the system simply proposes a change in exit time when congestion is high, then the user can avoid peak congestion periods, but the overall congestion reduction effect is insufficient

Engineering Contradiction:
Improvecongestion reduction effectVSAvoiduser convenience
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The system segments the platform resource into multiple alternative platforms. When the requested platform has high congestion, the system divides the user flow by proposing alternative platforms with lower congestion, thereby distributing the load and improving overall congestion reduction effectiveness while maintaining user convenience through automated recommendations

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system changes the parameter of platform selection from a fixed single-platform approach to a dynamic multi-platform approach. By evaluating congestion degrees of multiple platforms and recommending alternatives based on real-time conditions, the system achieves better congestion reduction while preserving ease of operation through automated decision-making

Inventive Principle:
Principle #35Parameter changes

2Productivity

If multiple vehicles exit at the same time and same destination, then the platform experiences high congestion, but individual vehicle efficiency is maximized

Engineering Contradiction:
Improvevehicle exit efficiencyVSAvoidplatform congestion
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system merges multiple individual exit requests into a coordinated carpooling arrangement. When detecting multiple vehicles with相同 exit time and destination, the system combines these requests and proposes carpooling, thereby reducing the number of separate exit operations and minimizing platform congestion while maintaining efficient vehicle utilization

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system implements automated detection and proposal of carpooling opportunities without requiring manual user coordination. The congestion degree determination unit automatically identifies potential carpooling scenarios, and the alternative solution proposal unit generates carpooling recommendations, enabling the system to self-optimize congestion reduction while preserving individual vehicle efficiency

Inventive Principle:
Principle #25Self-service

AI summary

Provided is an automatic parking service causes a vehicle that has arrived at a platform to enter one parking space among a plurality of parking spaces by autonomous driving and that causes the vehicle parked in the parking space exit the platform by autonomous driving. A congestion degree of a platform requested to be used in an entry-exit time zone specified by a user that uses the automatic parking service is determined when an entry-exit request in which one platform among the plurality of platforms is used is received from the user. The use of another platform is proposed to the user when the congestion degree of the platform requested to be used is high, the other platform having a lower congestion degree than the platform requested to be used.
