Barrier-Separated Charging Interface for Safe High-Speed Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Intrinsic safety circuits in electronic devices limit high-speed data transmission by restricting electrical power, which is necessary for timely exchange of large data such as video or audio between devices.
Innovation Solution
A charging system with a physical and electrical barrier separating communication modules, allowing wireless data exchange without the need for intrinsic safety circuits, thus enabling high-speed data transfer while maintaining safety against overcurrent and electrical overload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If intrinsic safety circuits with safety components are used to limit maximum electrical power, then safety against overcurrent and electrical overload is improved, but high-speed data transmission capability deteriorates
Solution Approach 1:
The communication system is segmented into two separate communication modules: a first communication module operating without intrinsic safety limitations for high-speed data transmission, and a second communication module operating under intrinsic safety circuits for safe power-limited communication. This segmentation allows each module to be optimized for its specific function without compromise
Solution Approach 2:
A wireless communication link acts as an intermediary between the first and second communication modules, enabling data transmission from the high-speed module to the safety-constrained module without direct electrical connection. This intermediary wireless channel transfers data while avoiding the speed limitations imposed by intrinsic safety circuits
