In-Vehicle Pairing via Intermediate Mediator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Passengers in commercial passenger vehicles face challenges in accessing a wide variety of entertainment content through their personal electronic devices due to cumbersome and repetitive pairing processes with in-vehicle entertainment systems, which can lead to signal interferences and unsuccessful pairing operations.
Innovation Solution
The implementation of an automatic pairing process between wireless electronic devices and in-vehicle entertainment systems using a pairing support software application, which simplifies the connection by storing pairing information and initiating the pairing operation without the need for passengers to manually repeat the process for multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual pairing process is used for each wireless electronic device, then pairing information can be accurately transmitted, but the pairing operation becomes cumbersome and time-consuming
Solution Approach 1:
The system performs preliminary actions by storing pairing information of wireless electronic devices in advance in the intermediate device. When a passenger wants to connect a device, the pairing information is already available, eliminating the need for repetitive manual pairing operations and reducing pairing time.
Solution Approach 2:
An intermediate device is introduced as a mediator between the source device (in-vehicle entertainment system) and wireless electronic devices. The intermediate device stores pairing information and facilitates automatic pairing operations, simplifying the connection process for passengers.
2Adaptability or versatility
If multiple pairing operations are performed simultaneously, then multiple devices can be connected, but signal interferences occur and pairing fails
Solution Approach 1:
Pairing information for multiple devices is stored in advance in the intermediate device. When pairing is needed, the system retrieves pre-stored information sequentially rather than performing simultaneous pairing operations, avoiding signal interference while maintaining the ability to connect multiple devices.
Solution Approach 2:
The pairing process is segmented into individual sequential operations for each device, with pairing information retrieved and processed one at a time from the stored data. This segmentation prevents signal interference that would occur with simultaneous pairing attempts while still enabling multiple device connections.
3Ease of operation
If automatic pairing is implemented, then pairing process is simplified, but pairing information security may be compromised
Solution Approach 1:
The intermediate device acts as a secure intermediary that stores and manages pairing information. It controls the automatic pairing process by retrieving and transmitting pairing information only to authorized devices, maintaining security while enabling simplified automatic pairing operations.

AI summary
An apparatus for assisting a pairing operation is provided. The apparatus comprises: a processor included in an intermediate device in communication with a source device to which a wireless electronic device is to be wirelessly connected through the pairing operation; and a storage included in the intermediate device and in communication with the processor, the storage configured to store pairing information of the wireless electronic device, the pairing information including a profile of the wireless electronic device that enables to complete the pairing operation with the source device. The storage further stores instructions, upon being executed, to instruct the processor to: determine to initiate the pairing operation for the wireless electronic device; and provide the pairing information of the wireless electronic device to the source device such that a wireless communication link is established between the wireless electronic device and the source device based on the pairing information of the wireless electronic device.
