Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a portable and easy-to-use speed control system for various vehicles that can enforce speed limits without requiring special software or training, particularly to address the challenges of teenage drivers exceeding speed limits and to conserve fuel.
Innovation Solution
A system comprising a GPS device connected to a speed limit processor that communicates with a database to provide real-time speed limit information, allowing the system to interface with vehicle processors to adjust speed, using commercially available GPS devices like Garmin or Tom Tom, and featuring automatic updates and emergency response capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a portable speed control system is used, then ease of operation is improved, but reliability may worsen due to potential disconnects between portable device and vehicle processor
Solution Approach 1:
The patent employs an intermediary communication interface that bridges the portable speed control device and the vehicle processor. This intermediary layer handles data transmission and protocol conversion, ensuring reliable communication while maintaining the portability and ease of operation of the control device.
2Adaptability or versatility
If the system interfaces with various vehicle processors, then adaptability is improved, but device complexity increases due to multiple interface requirements
Solution Approach 1:
The speed control device is designed with universal communication capabilities that can interface with multiple types of vehicle processors through standardized protocols. This multi-functionality approach allows a single device design to work across different vehicle types without increasing complexity, as the device automatically adapts to the connected processor type.
3Productivity
If real-time speed control is implemented, then productivity is improved through fuel conservation, but use of energy increases due to continuous monitoring and control operations
Solution Approach 1:
The system implements periodic speed control actions rather than continuous intervention. The portable speed control device monitors vehicle speed continuously but only activates control signals when speed deviations are detected, thereby achieving fuel conservation through targeted interventions while minimizing energy consumption during idle monitoring periods.
Data Source
AI summary
A system, a method and device for controlling speed of a moving vehicle, using portable and repositionable global positioning devices, speed limit processors, and a database of legal vehicle speed limits is in communication with the speed limit processor. Computer instructions instruct the speed limit processor to match the current location of the moving vehicle with a legal vehicle speed limit for a defined location using the database. The speed limit processor communicates the legal vehicle speed limit to the vehicle processor to control the speed of the moving vehicle.
