Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional UPS provides only AC backup power, then AC equipment can be protected during power disruptions, but DC equipment cannot receive backup power simultaneously
Solution Approach 1:
The UPS device is designed to provide both AC and DC power outputs simultaneously through a single unified system. The power module can concurrently output AC power to AC outlets and DC power to DC outlets, eliminating the need for separate UPS systems for different equipment types.
Solution Approach 2:
The patent combines AC and DC power supply functions into a single integrated UPS device. The power module integrates both AC inversion and DC output capabilities, merging what were previously separate systems into one unified power protection solution.
2Reliability
If separate AC and DC UPS systems are used, then each equipment type receives appropriate backup power, but system complexity and installation difficulty increase
Solution Approach 1:
A single UPS device performs multiple functions by providing both AC and DC backup power simultaneously. This multi-functional approach ensures reliable protection for both AC and DC equipment while simplifying system installation and management compared to using separate dedicated UPS systems.
3Device complexity
If a single power module provides both AC and DC output, then unified power management is achieved, but the switching control complexity increases
Solution Approach 1:
The controller monitors the power module's output and automatically adjusts switching between AC and DC power delivery based on real-time conditions. This feedback mechanism enables automated control of the power distribution, managing the complexity of simultaneous AC and DC output through intelligent monitoring and adjustment.
Solution Approach 2:
The power module employs dynamic switching capability to adaptively distribute power between AC and DC outputs. The controller can dynamically adjust the power distribution based on load requirements and input power availability, enabling flexible and adaptive power management.
