Antenna Connection Diagnosis Device for Vehicle Cable Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems lack an efficient method to diagnose the connection states of multiple cables simultaneously, making it difficult to determine which cables are not connected, which can lead to communication failures between antenna devices and information output devices.
Innovation Solution
A connection cable and antenna connection diagnosis device with built-in connection diagnosis connectors and resistors that apply a control voltage and measure voltages to determine if cables are connected, using a diagnoser to identify non-connected cables by comparing measured voltages with predetermined values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional cable connection diagnosis methods are used, then individual cable diagnosis is possible, but simultaneous diagnosis of multiple cables is not achieved and system complexity increases
Solution Approach 1:
Multiple diagnosis functions are merged into a single integrated diagnosis device. The device combines multiple voltage measurement circuits, each equipped with a resistor and voltage measurer, to simultaneously diagnose multiple cables through a single unified system rather than requiring separate diagnosis mechanisms for each cable.
Solution Approach 2:
The diagnosis device is designed with multi-functionality to handle various cable connection scenarios. Each voltage measurer can measure voltages across different cables, and the determiner can identify disconnections in multiple cables simultaneously, making the single device universal for diagnosing the entire cable system.
2Measurement precision
If multiple cables are diagnosed individually, then accurate connection status is determined, but diagnosis time increases
Solution Approach 1:
The diagnosis device performs preliminary simultaneous measurements across all cables in a single operation. By equipping each measurement circuit with a resistor connected to ground and using multiple voltage measurers operating concurrently, the system obtains connection status information for all cables at once, rather than sequentially diagnosing each cable one by one.
3Reliability
If connection diagnosis functionality is added to existing cables, then cable connection status can be determined, but manufacturing cost increases
Solution Approach 1:
The cable system incorporates self-diagnosis capability through integrated resistors and voltage measurement circuits built into the cable structure itself. Each cable includes its own diagnosis components (resistors connected to ground and voltage measurers), enabling the cables to self-diagnose their connection status without requiring external complex diagnosis equipment, thereby reducing overall manufacturing costs.
