Parking Stall Control Device Using Camera and Proximity Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unauthorized use of parking stalls by individuals other than the authorized user leads to misuse, resulting in improper use of the stall, financial loss, and potential shortages in parking availability, as existing systems lack effective control mechanisms.
Innovation Solution
A device mounted in the parking stall equipped with a camera, proximity sensors, a communication system, and a control unit that determines authorized use, emits audible warnings, and allows authorized users to approve or deny access, enabling live video streaming and payment options for unauthorized vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no control system is installed in the parking stall, then the stall remains accessible and easy to use, but unauthorized use occurs and revenue is lost
Solution Approach 1:
The system automatically detects vehicle presence via proximity sensors, identifies authorized users through camera-based recognition, and controls stall access without requiring manual intervention from parking authorities, enabling the system to serve itself
Solution Approach 2:
The patent replaces traditional mechanical parking control methods (physical barriers, manual signs) with electronic and optical systems including proximity sensors, cameras, and communication systems that automatically manage parking stall access
2Reliability
If a control system is installed to prevent unauthorized use, then parking control reliability improves, but the device complexity and cost increase
Solution Approach 1:
The control system performs multiple functions using integrated components: proximity detection, vehicle identification, authorized user verification, audible/visual warning, and communication all within a single unified apparatus that can be mounted on existing structures
Solution Approach 2:
The system uses adjustable parameters such as detection thresholds, warning message content, and communication protocols to adapt to different parking scenarios without requiring custom hardware design for each situation
3Productivity
If the stall is left uncontrolled, then the authorized user has full access, but the stall may remain unused leading to loss of revenue
Solution Approach 1:
The communication system provides real-time feedback to authorized users about stall availability and vehicle presence, enabling them to make informed decisions about when to use the stall and when to allow other authorized users access
Solution Approach 2:
The system dynamically adjusts stall accessibility based on real-time conditions, allowing the authorized user to grant temporary access to other authorized vehicles while maintaining overall control, thus optimizing parking utilization without permanent loss of revenue
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively prevents unauthorized use, ensures proper utilization of parking stalls, reduces revenue loss, and enhances parking availability by providing a controlled access system that alerts and deters unauthorized vehicles while allowing authorized users to manage access and payments.
Implementation Method 1
at least one proximity sensor and/or ultrasonic sensor arranged to detect entry of the vehicle into the parking stall
Implementation Method 2
at least one proximity sensor and/or ultrasonic sensor arranged to detect entry of the vehicle into the parking stall
Data Source
AI summary
An apparatus is provided for controlling parking in a parking stall including a camera to take images of a vehicle entering the parking stall, a proximity or ultrasonic sensor arranged to detect entry of the vehicle into the parking stall and a device for broadcasting an audible message to the driver. The device communicates with a web site associated with a plurality of stalls each having an associated control apparatus where the web site contains and provides data to a customer relating to any one or more of the associated stalls where authorized use can be purchased.
