Solution Overview

Problem

Automated valet parking lots at facilities are often misused by individuals who do not intend to use the facility, leading to congestion and unfair access for those who genuinely want to use the service.

Innovation Solution

A management system that includes a setting unit for defining a management area, an authentication unit for verifying vehicle usage, a tracking unit for monitoring vehicle position, and a notification unit that alerts users when they are outside the designated area, along with a penalty processing unit that imposes fines or usage restrictions for prolonged misuse.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If automated valet parking is made convenient and accessible, then user satisfaction and facility utilization improve, but misuse by non-facility users increases

Engineering Contradiction:

Improveconvenience of automated valet parkingVSAvoidmisuse by non-facility users

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system continuously monitors the portable terminal's position and provides feedback through alarm notifications when the user exits the management area. This feedback loop creates psychological suppression of misuse by making users aware of their location status and potential penalties

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs preliminary authentication before allowing parking lot usage, verifying that the user is associated with the facility. This preliminary action prevents non-facility users from accessing the automated valet parking service in the first place

Inventive Principle:

Principle #10Preliminary action

2Reliability

If penalty conditions are set to be strict and immediate, then deterrence of misuse improves, but false penalties for erroneous exits increase

Engineering Contradiction:

Improveaccuracy of penalty impositionVSAvoidcomplexity of penalty condition evaluation

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system notifies the user of alarm conditions before imposing penalties, giving advance warning and opportunity to return to the management area. This preliminary notification action prevents false penalties for erroneous exits while maintaining deterrence against intentional misuse

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The penalty system dynamically evaluates multiple conditions including duration of absence, number of alarm notifications, and whether the user returns before penalty imposition. This dynamic evaluation adapts to different usage scenarios and reduces false penalties while maintaining strict enforcement against deliberate misuse

Inventive Principle:

Principle #15Dynamics
