Oscillating Circuit for Battery Connector Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery connector systems are prone to accidental connections between pads, leading to discharge, electrolysis, and deterioration, especially due to parasitic conductances like humidity, which can result in false detection and equipment malfunction.
Innovation Solution
An oscillating circuit is integrated between the battery and equipment connectors, ensuring that only a complete connection activates the safety circuit, preventing parasitic conductances from causing electrolysis or false detections by using capacitive links that only transmit current when the oscillator is operational.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If the connector pads are energized permanently or periodically to detect equipment presence, then equipment presence detection is enabled, but electrolysis and deterioration of the pads occur due to parasitic conductances like humidity
Solution Approach 1:
The patent applies periodic action by using an oscillating circuit that operates only during specific periods when equipment is properly connected. The circuit oscillates at a defined frequency only when the complete connection path exists, thereby enabling detection without continuous energization that would cause electrolysis. The periodic oscillation allows detection while minimizing harmful effects.
Solution Approach 2:
The patent changes the parameter of electrical state from continuous DC energization to AC oscillation at a specific frequency. By transforming the detection mechanism from steady-state voltage/current to frequency-based oscillation detection, the system can distinguish between parasitic conductances (which cannot sustain oscillation) and proper equipment connections (which complete the oscillating circuit).
2Reliability
If a safety circuit is introduced to prevent accidental connections, then protection against discharge and electrolysis is improved, but device complexity increases
Solution Approach 1:
The patent merges the detection function and safety function into a single integrated oscillating circuit system. The same oscillating circuit that detects equipment presence also serves as the safety mechanism by preventing current flow unless oscillation is detected. This eliminates the need for separate detection and safety circuits, thereby reducing overall complexity while maintaining reliability.
Solution Approach 2:
The oscillating circuit serves itself dual purposes: it detects equipment presence and simultaneously provides safety protection. The circuit's own oscillation state indicates both detection and safety conditions, eliminating the need for additional dedicated safety components and reducing system complexity.
