Head Unit Handset Interface Direct Asset Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for linking mobile devices, such as Bluetooth technology, require synchronization of assets like contact lists, leading to duplicate copies that can become obsolete and require frequent updates, complicating the user experience, especially in environments like moving vehicles where direct access and clear communication are challenging.
Innovation Solution
A method and system that enable direct communicative coupling between handheld mobile devices and head units, allowing the head unit to emulate the mobile device's user interface and access its assets without duplication, using wireless technologies like WiFi or NFC for linking, and allowing the head unit to act as a proxy for the mobile device in operations like phone calls and text messaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Bluetooth technology is used to link mobile devices, then wireless communication between devices is enabled, but asset synchronization creates duplicate copies that become obsolete and require frequent updates
Solution Approach 1:
The patent extracts the asset data from the mobile device and transmits it directly to the head unit device, eliminating the need for synchronization between duplicate copies. The head unit obtains direct access to the mobile device's assets through a direct communication link, removing the intermediary synchronization step that causes complexity and obsolescence issues.
Solution Approach 2:
The patent introduces a direct communication channel as an intermediary between the mobile device and head unit, allowing assets to be accessed and transmitted without requiring synchronization protocols. This direct link acts as a mediator that enables the head unit to obtain fresh data directly from the source without creating and managing duplicate copies.
2Reliability
If assets are synchronized between devices, then both devices have access to the same data, but duplicate copies become obsolete and require frequent updates
Solution Approach 1:
The patent extracts asset data directly from the mobile device and transmits it to the head unit, eliminating the synchronization process that creates obsolete duplicate copies. The head unit receives data directly from the source, ensuring reliability without the time loss associated with frequent updates and synchronization checks.
Solution Approach 2:
The patent performs preliminary transmission of asset data from the mobile device to the head unit before use. By extracting and transmitting assets in advance through direct communication, the system ensures data availability at the head unit without requiring subsequent synchronization updates, eliminating time loss from frequent refreshes.
3Ease of operation
If the head unit emulates the mobile device interface, then user interaction is simplified in noisy environments, but direct access to assets requires established communication link
Solution Approach 1:
The patent introduces a communication application as an intermediary that establishes a direct link between the mobile device and head unit. This intermediary handles the complex communication protocols and asset access requirements, allowing the head unit to emulate the mobile device interface seamlessly while managing the technical complexity of direct asset access through the communication channel.
Data Source
AI summary
A method of communicatively coupling a handheld mobile device and a head unit comprising monitoring, by the handheld mobile device, a port of the handheld mobile device; sending, by the handheld mobile device, an application to the head unit when the head unit device contacts the handheld mobile device via the port of the handheld mobile device; and conducting, by the handheld mobile device, an operation of the handheld mobile device, using the head unit device as the user interface for the handheld mobile device.
