Vehicle Wireless Device Connection Management with Switchover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing short-range wireless communication systems in vehicles often limit the ability to easily switch between multiple connected devices, restricting the primary connected device and offering limited functionality to secondary devices, which can be inconvenient for users with multiple mobile devices.
Innovation Solution
A method for managing short-range wireless communications in vehicles that allows for the switchover of primary connected devices based on received wireless signals, using protocols like NFC and Bluetooth, enabling the vehicle electronics to disconnect one device and connect another, thereby optimizing device priority and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the vehicle restricts operation to a single primary connected device, then system complexity is reduced and management is simplified, but user convenience and adaptability deteriorate when users need to switch between multiple devices
Solution Approach 1:
The patent implements dynamic device priority management where the primary connected device can be switched based on received wireless signals. The system transitions from a static single-device restriction to a dynamic multi-device support system, allowing the primary device designation to change over time based on user needs and signal conditions, thereby resolving the contradiction between simplified management and adaptability
Solution Approach 2:
The vehicle system automatically detects wireless signals from mobile devices and autonomously performs the switchover process without requiring manual user intervention. The system self-manages the complexity of device switching by implementing automatic signal detection, priority determination, and connection management, thus maintaining simplicity while enabling multi-device adaptability
2Adaptability or versatility
If the vehicle supports multiple connected devices simultaneously, then adaptability and user convenience are improved, but device management complexity and system resource requirements increase
Solution Approach 1:
The patent applies different quality levels to different connected devices by designating one device as primary with full functionality and allowing secondary devices with limited functionality. This local differentiation approach allows the system to support multiple devices simultaneously while managing complexity by providing different service levels, thus resolving the contradiction between multi-device support and management complexity
Solution Approach 2:
The system implements partial action by providing full vehicle functionality to the primary device while offering limited functionality to secondary devices. This approach allows the system to support multiple devices without the full complexity of managing equal-level connections for all devices, effectively balancing adaptability with manageable system complexity
