Engineering Contradiction Analysis
1Reliability
If external fault detection means are added to existing systems, then safety is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple detection functions (current detection, voltage detection, external fault detection) into a single integrated output stage. The current detection means and voltage detection means are merged with the output switches to form a unified safety monitoring system, eliminating the need for separate detection devices and reducing overall system complexity.
Solution Approach 2:
The output stage is designed to perform multiple functions simultaneously: it provides control voltage to the consumer, detects current flow, monitors voltage levels, and identifies external faults. This multi-functional design eliminates the need for separate dedicated detection systems, thereby improving safety without proportionally increasing device complexity.
2Reliability
If current detection means are added between output switches and terminals, then fault detection capability is improved, but device complexity increases
Solution Approach 1:
The current detection means is integrated directly into the output stage circuitry between the output switches and terminals P/M. This merging approach allows fault detection without requiring separate external detection devices, thereby improving reliability while minimizing the increase in device complexity.
