Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitoring systems for vehicle entry and exit, such as ticketing systems and access control systems, face issues with accuracy, user distraction, and inconvenience due to the need for physical tickets or dedicated devices, especially in environments like underground carparks and residential buildings, where satellite positioning is inaccurate or unavailable, and Bluetooth beacons suffer from interference.
Innovation Solution
A system using reflector antennas with transmitters to define detection areas, where mobile devices determine their location based on signal strengths from multiple transmitters, allowing accurate detection and communication with access control systems without the need for physical tickets or additional devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If satellite positioning systems are used for vehicle monitoring, then coverage area is improved, but measurement precision deteriorates in underground environments
Solution Approach 1:
The patent introduces wireless transmitters installed at strategic locations within the parking facility as intermediary devices. These transmitters create local wireless zones that enable position determination without relying on satellite signals, thus solving the problem of poor positioning accuracy in underground environments while maintaining broad coverage through distributed transmitter placement.
Solution Approach 2:
The patent replaces satellite-based mechanical/electromagnetic positioning systems with a wireless infrastructure-based positioning approach. Instead of relying on external satellite signals that penetrate poorly through concrete structures, the system uses locally generated wireless signals from installed transmitters to determine vehicle positions accurately within the facility.
2Device complexity
If Bluetooth beacon systems are used for position detection, then device complexity is reduced, but measurement precision deteriorates due to environmental interference
Solution Approach 1:
The patent uses wireless transmitters as intermediary devices that create controlled signal zones. By strategically positioning multiple transmitters throughout the facility, the system establishes distinct wireless coverage areas that enable accurate position determination through signal strength comparison, overcoming Bluetooth's vulnerability to environmental interference while maintaining system simplicity.
Solution Approach 2:
The patent applies local quality by creating distinct wireless signal zones around each transmitter. Each transmitter serves a specific local area with optimized signal characteristics, allowing the system to determine position based on which local zone the mobile device is in, thereby improving detection accuracy while keeping individual transmitter devices simple.
3Reliability
If physical ticketing systems are used for access control, then reliability is improved, but ease of operation deteriorates due to driver distraction
Solution Approach 1:
The patent implements self-service by enabling automatic identification and position determination of vehicles through wireless transmitters and mobile devices. The system automatically tracks vehicle entry and exit without requiring drivers to manually present tickets or interact with access control devices, thereby maintaining reliable access control while eliminating driver distraction and improving ease of operation.
Solution Approach 2:
The patent replaces the mechanical ticket handling system with a wireless-based automatic identification system. Instead of physical tickets that require manual collection, presentation, and validation, the system uses wireless signal detection and position tracking to automatically manage access control, improving both driver convenience and operational reliability.
4Measurement precision
If manual ticket collection and insertion is required, then measurement precision is maintained, but productivity deteriorates due to extensive queues
Solution Approach 1:
The patent implements self-service positioning and identification where mobile devices automatically interact with wireless transmitters to determine vehicle position and validate access. This eliminates the need for manual ticket handling at entry and exit points, allowing multiple vehicles to be processed simultaneously without queues, thereby dramatically improving productivity while maintaining accurate position determination through wireless signal measurement.
Solution Approach 2:
The patent enables continuous operation by allowing simultaneous processing of multiple vehicles through automatic wireless-based identification and position determination. Unlike manual ticket systems that require sequential processing, the wireless system can handle multiple vehicles concurrently, maintaining continuous vehicle throughput without interruption or queue formation.
