Redundant Power Supply Circuit Layout to Prevent Cross-Circuit Faults
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supply systems lack redundancy, which can lead to failure when one component fails, disrupting power supply to load devices.
Innovation Solution
A power supply system with multiple power supply circuits and connection circuits, where connection devices are strategically placed to isolate and connect circuits to maintain redundancy, preventing overcurrent flow and short circuits, and utilizing power storage devices to ensure continuous power supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connection devices are placed close together in the power supply system, then the system structure is simpler, but the redundancy is reduced and the risk of simultaneous failure increases
Solution Approach 1:
The connection circuit is divided into two separate connection devices (first connection device and second connection device) positioned at opposite ends of the circuit. This segmentation isolates potential failure points and maintains redundancy even if one connection device fails, as the other end remains functional.
Solution Approach 2:
The connection devices are distributed along the spatial dimension of the connection circuit rather than being concentrated at a single location. By placing one connection device at one end and another at the opposite end, the system creates spatial redundancy that enhances reliability without significantly increasing overall system complexity.
2Reliability
If multiple power supply circuits are added to increase redundancy, then the reliability improves, but the system complexity and cost increase
Solution Approach 1:
The power supply system uses identical power supply circuits (first power supply circuit and second power supply circuit) that can interchangeably serve different load devices. Each circuit is designed with the same functionality, allowing any circuit to supply power to any load, thereby providing redundancy without requiring complex specialized configurations for each circuit.
