Solution Overview
Problem
Existing radio-wave communication devices for vehicles are limited in controlling additional information from connected electronic devices through the car radio and have complex installation processes due to multiple power cables and connectors.
Innovation Solution
A radio-wave communication device with a two-way radio module and an interfacing module that uses a single electronic connection port associated with the car radio's antenna input, incorporating a modulation circuit and a processing unit to control and display various types of information, and simplifies installation with a single cable connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple power cables and connectors are used to interface the communication device with the car radio, then the connection reliability is improved, but the installation complexity increases
Solution Approach 1:
The patent combines multiple separate connection functions (power supply, audio signal transmission, control signals) into a single integrated cable connection between the communication device and the car radio. This single cable replaces the traditional multiple separate cables and connectors, thereby reducing installation complexity while maintaining all necessary connection functions through integrated design
2Device complexity
If a single cable connection is used to simplify installation, then the installation complexity is reduced, but the control of additional information from connected devices is limited
Solution Approach 1:
The single cable connection is designed with multi-functional capability to handle multiple types of signals simultaneously. The interface supports power supply, audio signal transmission, and control signals for displaying additional information from connected electronic devices on the car radio display, thereby achieving universal compatibility and full functionality through a simplified single-cable connection
