Solution Overview
Problem
Existing methods for operating mobile devices in motor vehicles are limited by the need for the vehicle to be connected to the internet for software and data access, and they do not effectively utilize the advanced computing capabilities of modern mobile devices, restricting the use of modern applications and input devices.
Innovation Solution
A method that enables bidirectional data exchange between a mobile device and a motor vehicle, allowing an application program to run on the mobile device, which communicates with external networks to access and use data and software, even if the vehicle is not connected to the internet, utilizing the mobile device's computing power and the vehicle's input devices for enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the vehicle is connected to the internet for software and data access, then the vehicle can access external networks and data, but the device complexity and requirement for internet connectivity increase
Solution Approach 1:
The system segments the computing functions by allowing the mobile device to run the application program independently while the vehicle provides only input devices and display. This separation eliminates the need for the vehicle to have internet connectivity capabilities, as the mobile device handles all software processing locally.
Solution Approach 2:
The mobile device acts as an intermediary between the user and the vehicle system. It receives input from vehicle input devices, processes the input through the application program, and outputs results to vehicle display devices, thereby eliminating the need for the vehicle to directly access external networks.
2Adaptability or versatility
If the vehicle uses its own computing capacity for running applications, then the vehicle can execute software directly, but older vehicles without sufficient computing power cannot use modern applications
Solution Approach 1:
The computing functions and application programs are extracted from the vehicle system and placed on the mobile device. This allows modern applications with advanced computing requirements to run on the mobile device while the vehicle system remains simple, enabling older vehicles to support modern applications through the mobile device's computing power.
Solution Approach 2:
The mobile device serves multiple functions: it runs the application program, processes input from various vehicle input devices, generates output for display, and manages communication with the vehicle system. This universal approach allows a single device to provide the computing capacity needed for modern applications across different vehicle platforms.
3Power
If the vehicle provides all input and output functions, then the vehicle system is self-sufficient, but the mobile device's computing capabilities are underutilized
Solution Approach 1:
Instead of the vehicle providing all input and output functions and the mobile device merely displaying information, the system is inverted: the mobile device becomes the primary processing unit that runs applications and generates all output, while the vehicle provides only basic input devices and display hardware. This inversion maximizes utilization of the mobile device's computing capabilities.
