Portable Vehicle Communication Device for External Operator Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle operators, such as police officers and commercial truck drivers, face challenges in communicating effectively with their vehicle-installed communication systems when outside the vehicle, limiting their ability to access routine functions, report emergencies, or detect vehicle theft in real-time.
Innovation Solution
A vehicle communication device comprising a portable unit that wirelessly communicates with a vehicle-installed unit, enabling operators to access vehicle information, report emergencies, and detect vehicle movement, using Bluetooth, GPRS/CDMA, and GPS technologies for seamless communication and location tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the operator uses the vehicle installed unit only when inside the vehicle, then the communication system remains simple, but the operator cannot access vehicle functions or report emergencies when outside the vehicle
Solution Approach 1:
A portable unit serves as an intermediary device that the operator carries outside the vehicle. This portable unit wirelessly communicates with the vehicle installed unit, enabling the operator to access vehicle functions, report emergencies, and receive notifications while outside the vehicle, without requiring complex modifications to the vehicle installed unit itself
Solution Approach 2:
The communication system is divided into two separate components: a vehicle installed unit that remains in the vehicle and a portable unit that the operator carries. This segmentation allows the operator to access vehicle functions outside the vehicle while keeping the vehicle installed unit relatively simple and dedicated to vehicle-based operations
2Adaptability or versatility
If the operator carries a cell phone for calls outside the vehicle, then communication is possible, but the operator cannot access vehicle-specific information or functions
Solution Approach 1:
The portable unit combines the functionality of a standard communication device with access to vehicle-specific information and functions. By integrating these capabilities into a single portable unit that the operator carries, the system eliminates the need for separate cell phones while providing comprehensive communication and vehicle access capabilities outside the vehicle
3Reliability
If the vehicle installed unit does not provide external communication capability, then the system remains simple, but the operator cannot report emergencies or access help when outside the vehicle
Solution Approach 1:
The portable unit acts as an intermediary that enables emergency reporting and external communication. When the operator needs to report an emergency or access help while outside the vehicle, the portable unit wirelessly communicates with the vehicle installed unit, which then interfaces with external communication networks, providing reliable emergency capability without significantly complicating the vehicle installed unit
4Reliability
If the operator does not receive immediate notification when the vehicle is stolen, then the system remains passive, but the operator cannot respond quickly to vehicle theft
Solution Approach 1:
The vehicle installed unit continuously monitors vehicle status and provides immediate feedback to the portable unit when abnormal conditions such as unauthorized movement or theft are detected. This automated feedback mechanism enables the operator to receive real-time notifications of vehicle theft or unauthorized use, allowing for immediate response without requiring the operator to actively check on the vehicle

AI summary
An example vehicle communication device includes a vehicle installed unit and a portable unit in communication with the vehicle installed unit. The portable unit communicates a message through the vehicle installed unit to a remote location, and the vehicle installed unit adds information to the message.
