Connector Water Detection with Simultaneous Cable Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for detecting water in connectors are inefficient, as they require separate processes for water detection and cable recognition, increasing the time and complexity of determining whether foreign substances like water have been introduced into connectors, which can lead to corrosion.
Innovation Solution
An electronic device with a water detection circuit and a connection sensing circuit that simultaneously detect water and recognize cables using detection and sensing pins, allowing for simultaneous operation and reducing the time required for recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate processes are used for water detection and cable recognition, then each function can be performed independently, but the time required for detection and recognition increases
Solution Approach 1:
The patent combines water detection and cable recognition into a single integrated process. The water detection circuit and connection sensing circuit share common pins (CC1 and CC2) and operate simultaneously under unified control of the application processor, eliminating sequential execution overhead and reducing total detection time while maintaining both functions' reliability
2Reliability
If separate processes are used for water detection and cable recognition, then each function can be independently optimized, but the overall complexity of the system increases
Solution Approach 1:
The patent implements multi-functionality by enabling the CC1 and CC2 pins to serve dual purposes: both water detection and cable recognition. The same physical pins and circuits perform multiple functions through different detection modes controlled by the application processor, reducing the need for separate dedicated components and simplifying the overall system architecture
