Solution Overview

Problem

In parking lot management systems, manually driven vehicles often park outside the designated lines, rendering the space unusable for autonomous vehicles, leading to inefficient use of parking lots.

Innovation Solution

A system that includes a vehicle parked position detection unit to identify vehicles not parked within the lines and a movement management unit to either move the vehicle or adjust the parking lines so that the vehicle is parked correctly inside the lines.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manually driven vehicles are allowed to park freely in the parking lot, then ease of operation is improved, but parking space utilization deteriorates due to vehicles parking outside lines

Engineering Contradiction:
Improveease of parkingVSAvoidparking space utilization
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The system continuously monitors vehicle positions using detection units and provides feedback to the management server. When a vehicle is detected outside the parking lines, the system generates notifications to the driver and automatically triggers corrective actions, creating a closed-loop feedback mechanism that maintains parking discipline while preserving driver convenience.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system enables manually driven vehicles to self-correct their parking positions through automated notifications and guidance. The detection units and management server work together to provide real-time feedback to drivers, allowing them to self-adjust their vehicle positions without requiring manual intervention from parking lot staff.

Inventive Principle:
Principle #25Self-service

2Productivity

If the parking lines are moved to accommodate vehicles parked outside, then parking space utilization is improved, but manufacturing precision deteriorates due to frequent line repositioning

Engineering Contradiction:
Improveparking space utilizationVSAvoidparking line position accuracy
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The system dynamically adjusts parking line positions based on real-time vehicle detection data. When vehicles are consistently detected outside certain areas, the management server automatically recalculates and repositions the virtual parking lines using the detection unit information, allowing the system to adapt to actual parking patterns while maintaining overall precision through automated calculations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the parameters of parking lines (position, orientation, boundaries) based on detected vehicle parking patterns. The management server processes detection data and automatically adjusts line parameters to optimize space utilization while maintaining accurate and consistent virtual boundary definitions through computational methods.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If automated detection and correction systems are implemented, then parking space utilization is improved, but device complexity increases

Engineering Contradiction:
Improveparking space utilizationVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The management server performs multiple functions including receiving detection data, analyzing vehicle positions, generating notifications, calculating corrected parking lines, and controlling output devices. This multi-functional approach consolidates complex operations into a single centralized system, reducing overall system complexity while maintaining high parking space utilization through automated management.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The management server acts as an intermediary between the detection units and the output devices (notifications, line adjustments). It processes raw detection data, makes decision logic, and generates appropriate control signals, simplifying the interaction between different system components and reducing the complexity of direct point-to-point connections.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Whether a vehicle is parked inside parking lines in a parking lot is detected. When the vehicle is detected not parked inside the parking lines, either the vehicle or the parking lines are moved in such a manner that the vehicle is parked inside the parking lines.
