Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies do not effectively enable seamless connectivity and full operation of a smartphone's screen and functions on a vehicle's touch screen, limiting the integration and usability of mobile devices with vehicle infotainment systems.
Innovation Solution
A controller mediates between a smartphone and a vehicle touch screen, transmitting video signals and touch actions, allowing the smartphone to respond to touch inputs on the vehicle screen, and switching between media computer and smartphone feeds to the touch screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile phone is connected to a vehicle media center, then information from the mobile phone can be displayed on the vehicle output unit, but the mobile phone cannot be fully operated via the vehicle touch screen
Solution Approach 1:
An interface computer is introduced as an intermediary between the mobile terminal and the vehicle operating unit. The interface computer receives information from the mobile terminal, processes it, and transmits it to the vehicle output unit for display. This mediator enables full operation of the mobile phone through the vehicle touch screen by translating touch inputs into corresponding mobile phone commands.
2Area of stationary object
If the touch screen of the mobile phone is displayed on the vehicle touch screen, then the display area is increased, but the touch coordinate mapping becomes complex
Solution Approach 1:
The patent replaces complex mechanical coordinate mapping systems with an electronic software-based solution. The interface computer uses software algorithms to automatically map touch coordinates from the vehicle touch screen to the mobile phone screen, eliminating the need for complex physical coordinate conversion mechanisms and simplifying the overall system.
3Adaptability or versatility
If various functions of the mobile phone are applied to the vehicle A/V system, then the functionality of the vehicle system is enhanced, but the system complexity increases
Solution Approach 1:
The interface computer is designed as a universal multi-functional device that can handle various mobile phone functions including display output, hands-free communication, camera operations, and navigation. By creating a single multi-functional interface rather than separate dedicated systems for each function, the patent reduces overall system complexity while maintaining enhanced functionality.

AI summary
Systems and methods for promoting connectivity between a mobile communication device having a touch screen and a vehicle touch screen installed in a vehicle are disclosed. According to an embodiments, a system may include a controller configured to: connect to the mobile communication device and to the vehicle touch screen. The controller may also be configured to receive video signal of a current screen video image shown on the touch screen of the mobile communication device and transmit the current video image to the vehicle touch screen, causing a corresponding video image of the current screen video image to be displayed on the vehicle touch screen. The controller may further be configured to receive a signal indicative of a touch action that was performed on the vehicle touch screen, and cause the mobile communication device to respond as if a touch action corresponding to the touch action that was performed on the vehicle touch screen was performed on the touch screen of the mobile communication device.
