Vehicle Device Installation Tool With Data Bus Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aftermarket installers face challenges in simplifying the installation and configuration of devices in vehicles with data bus systems due to variations in communication protocol standards and unique wiring configurations, requiring access to vehicle-specific information and technical support, often necessitating remote assistance and complex troubleshooting.
Innovation Solution
A tool system that includes a module connected to the vehicle's data bus in wireless communication with a handheld processor, such as a smartphone or tablet, providing access to vehicle-specific information, technical support, and enabling testing, troubleshooting, and configuration of devices, with features like logging data messages and sharing experiences among installers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If installers access vehicle-specific information through remote computer terminals, then technical support is available, but installation time increases and convenience decreases
Solution Approach 1:
The patent introduces a portable computing device as an intermediary between the installer and the remote server. This device provides local caching of vehicle-specific information and wireless communication capabilities, allowing installers to access technical data on-site without returning to remote terminals, thus reducing installation time while maintaining reliable access to vehicle-specific information
Solution Approach 2:
The system performs preliminary actions by pre-fetching and caching vehicle-specific information, wiring diagrams, and technical data onto the portable computing device before the installer arrives at the vehicle. This allows immediate access to required information during installation without needing to query remote terminals in real-time
2Reliability
If installers contact device manufacturers for technical assistance, then troubleshooting support is available, but installation process is interrupted
Solution Approach 1:
The portable computing device empowers installers with self-service capabilities by providing on-device access to wiring diagrams, technical manuals, and troubleshooting guides specific to the vehicle and device being installed. Installers can resolve issues independently without interrupting the installation process to contact manufacturers, thereby maintaining both reliable technical support and installation efficiency
3Manufacturing precision
If testers verify actuator movement by physical observation, then installation accuracy is confirmed, but additional personnel are required
Solution Approach 1:
The patent replaces the mechanical observation method with electronic/digital verification. The portable computing device can communicate with vehicle actuators and sensors through the data bus, allowing the installer to verify actuator movement and installation accuracy by viewing real-time status on the device's display, eliminating the need for a second person to physically observe and confirm actuator operation
Data Source
AI summary
A device installation system for providing a tool for use by installers to assist in obtaining vehicle specific information such as wiring diagrams, technical information and direct access to technical support technicians. The system further provide for testing, trouble shooting and configuration of installed vehicle devices.
