Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tracking and monitoring devices for vehicle speeding are cumbersome, expensive, and difficult to install, limiting their effectiveness in enforcing traffic laws and monitoring vehicle usage, especially in situations where resources for traffic enforcement are limited.
Innovation Solution
A system that determines the speed of a vehicle using GPS signals from wireless devices and generates notifications if the vehicle exceeds the speed limit, utilizing a wireless communication network to alert the driver or a third party, such as a parent or employer, and can be mandated for new vehicles as part of annual inspections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional tracking and monitoring devices are used to monitor vehicle speed, then speed monitoring capability is achieved, but device complexity and installation difficulty increase
Solution Approach 1:
The patent applies universality by enabling standard wireless devices (cell phones, PDAs, navigation systems) to perform speed monitoring functions that previously required specialized tracking devices. The system uses the wireless device's existing GPS capabilities and wireless communication functions to achieve speed monitoring, eliminating the need for separate dedicated monitoring hardware.
Solution Approach 2:
The wireless device serves itself by using its own GPS receiver and processing capabilities to determine its location and speed. The device independently calculates speed based on location changes over time and communicates this information wirelessely without requiring external monitoring infrastructure or specialized hardware.
2Reliability
If specialized tracking devices are deployed for speed monitoring, then enforcement capability is improved, but cost increases
Solution Approach 1:
The patent leverages the widespread availability of inexpensive wireless devices that consumers already own. Rather than deploying expensive specialized tracking hardware, the system uses readily available consumer electronics, dramatically reducing deployment costs while maintaining enforcement capability through wireless communication with authorities.
Solution Approach 2:
The system achieves enforcement capability through the wireless device's existing communication infrastructure rather than requiring specialized enforcement hardware. The wireless device can communicate speed information to law enforcement or third parties using standard wireless protocols, eliminating the need for expensive dedicated enforcement equipment.
3Productivity
If more traffic police are deployed to enforce speed limits, then traffic law enforcement improves, but municipal budget requirements increase
Solution Approach 1:
The patent replaces the mechanical system of human traffic police monitoring and enforcement with an automated electronic system. The wireless device automatically tracks speed via GPS, compares it to speed limits, and communicates violations without requiring human officers, thereby improving enforcement efficiency while reducing the need for physical law enforcement resources.
Solution Approach 2:
The system performs self-monitoring and self-reporting of speed violations. The wireless device independently determines when speed limits are exceeded and automatically communicates this information to authorities or third parties, eliminating the need for human observers and enabling continuous enforcement without additional personnel.
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
The system effectively monitors and enforces speed limits, reducing reckless driving by alerting drivers and stakeholders, thereby enhancing road safety and compliance with traffic regulations without the need for extensive law enforcement resources.
Implementation Method 1
The location of the wireless device is determined by a GPS receiver in the wireless device
Implementation Method 2
The speed is then calculated by dividing the distance between the two locations by the interval between the two times

AI summary
A vehicle speeding alert system is implemented on a GPS enabled wireless device in communication with a wireless network. The alert system periodically determines the speed of a vehicle by determining the speed of the wireless device carried therein, using GPS signals received by the wireless device. For example, speed can be calculated by dividing a certain distance that the wireless device travels by the time it takes to travel that distance. The vehicle's speed is then compared to the speed limit of the roadway on which the vehicle is traveling. The speed limit is determined by comparing the wireless device's location to map data relating to the geographic area around the location. The map data may be stored on the wireless device, or obtained from a map database accessible over the network. If the vehicle speed is above the speed limit, a notification or alert is issued.
