Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing V2X communication systems face inefficiencies due to the broadcast of unnecessary messages, leading to resource waste, as they lack effective measures for selective communication with external electronic devices.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If V2X communication systems broadcast messages using standard protocols, then communication coverage and compatibility are improved, but resource waste increases due to unnecessary messages being delivered to all external electronic devices
Solution Approach 1:
The patent segments the broadcast message into two distinct parts: a first message using a first protocol that can be received by all external electronic devices (ensuring compatibility), and a second message using a second protocol that contains specific connection information for targeted communication (reducing resource waste). This segmentation allows the system to maintain broad compatibility while efficiently directing resources only to relevant devices.
2Adaptability or versatility
If V2X communication systems broadcast connection requests to all external devices, then communication reach is improved, but communication efficiency deteriorates due to handling responses from unnecessary devices
Solution Approach 1:
The patent applies preliminary action by first broadcasting a connection request using a first protocol to identify potential communication targets, then selectively establishing second protocol-based communication only with devices that respond positively. This preliminary filtering step ensures broad reach while improving efficiency by avoiding unnecessary communication setup with irrelevant devices.
3Device complexity
If the system uses a single communication protocol for all messages, then system complexity is reduced, but communication precision deteriorates due to inability to selectively target specific external electronic devices
Solution Approach 1:
The patent applies local quality by using different communication protocols for different purposes: a first protocol for broad broadcasting and device identification, and a second protocol for precise targeted communication. This allows the system to maintain simplicity where needed while achieving precision where required, with each protocol optimized for its specific function.

AI summary
An electronic device includes at least one communication circuit, and a processor electrically connected with the at least one communication circuit. The processor may be configured to select an external electronic device in response to a user input, broadcast, through the at least one communication circuit using a first protocol, a connection request for a second protocol-based communication with the external electronic device, receive a response to the connection request from the external electronic device through the at least one communication circuit, and perform communication with the external electronic device through the at least one communication circuit using a second protocol, based on connection information about the external electronic device for the second protocol-based communication, the connection information being contained in the response.
