Solution Overview

Problem

Conventional parking management systems face administrative burdens when valets park vehicles in shared facilities, requiring manual updates or payments to avoid citations, which is inefficient under time pressure.

Innovation Solution

An automated system using multiple cameras networked with a central computer to identify vehicles entering and exiting a parking facility, with a secondary camera at a valet/check-in area to create temporary permits, reducing the need for manual updates and payments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual updates are performed for each valet parking event, then parking citations can be avoided, but administrative time and efficiency deteriorate under time pressure

Engineering Contradiction:
Improveavoidance of parking citationsVSAvoidadministrative time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary action by capturing vehicle identifiers at the valet area before the vehicle enters the parking facility. The central computer proactively creates temporary permit records in advance, so that when the vehicle enters and is detected by entrance cameras, the permit is already established and no manual intervention is needed to avoid citations.

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If the parking monitoring system is updated for each valet parking event, then accurate tracking is achieved, but system complexity and operational burden increase

Engineering Contradiction:
Improvetracking accuracyVSAvoidsystem operational complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system implements self-service by automatically capturing vehicle identifiers at the valet area, comparing them against the database of authorized vehicles, and generating temporary permits without requiring any manual administrative action. The system serves itself by autonomously managing the entire permit creation and tracking process for valet vehicles.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary action by pre-capturing vehicle identifiers at the valet area before vehicles enter the parking facility. This advance capture and automatic database comparison eliminates the need for subsequent manual updates, maintaining tracking accuracy while reducing operational complexity.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If automated LPR cameras are used at entrance and exit, then parking session tracking is efficient, but valet vehicles incur unnecessary charges without manual intervention

Engineering Contradiction:
Improveparking session tracking efficiencyVSAvoidcharging accuracy
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system introduces an intermediary solution by creating a temporary permit record in the database that acts as a mediator between the automated LPR tracking system and valet vehicles. This intermediary permit record allows the automated system to efficiently track parking sessions while simultaneously preventing erroneous charges for authorized valet vehicles.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A parking facility employs an entrance camera and an exit camera to identify vehicles entering and exiting the parking facility in order to manage parking events. A secondary camera is located remote from the parking facility and nearby a hotel, restaurant or other venue where there exists a valet or check-in area. Each of the entrance, exit and secondary cameras are networked with a central computing system. Vehicles passing by the secondary camera are identified and a temporary parking permit for the parking facility can be quickly established based upon the data collected by the secondary camera so that hourly charges are not incurred when the vehicle parks in the parking facility.
