Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple inverters are used in custom-designed UPS for specific voltages, then voltage adaptability is improved, but device complexity increases and efficiency decreases
Solution Approach 1:
The patent implements a universal UPS design where a single inverter can operate with battery sets configured in different series/parallel arrangements to support multiple voltage scenarios. The inverter is designed to universally accept various DC voltage inputs from the battery configurations and convert them to the required AC output voltage, eliminating the need for multiple voltage-specific inverters while maintaining adaptability to different voltage requirements
2Adaptability or versatility
If multiple inverters are used in custom-designed UPS, then voltage adaptability is improved, but energy efficiency deteriorates
Solution Approach 1:
The patent merges the functionality of multiple voltage-specific inverters into a single inverter unit. This single inverter is capable of handling multiple voltage scenarios by receiving DC power from battery sets that can be configured in different series or parallel connections. The consolidation eliminates redundant conversion stages and reduces overall energy losses associated with having multiple separate inverter systems
3Manufacturing precision
If fixed battery sizing is used in custom-designed UPS, then manufacturing precision is improved, but adaptability deteriorates
Solution Approach 1:
The patent implements a dynamic battery configuration system where the battery sets can be reconfigured between series and parallel connections based on the voltage requirements. This dynamic reconfigurability allows the same physical battery sets to adapt to different voltage scenarios without requiring custom-designed battery banks for each voltage level, thus maintaining manufacturing precision while achieving high adaptability
4Adaptability or versatility
If multiple inverters are used in custom-designed UPS, then voltage adaptability is improved, but heating issues worsen
Solution Approach 1:
The patent extracts and eliminates the redundant inverter components from the system design. By using a single inverter instead of multiple inverters for different voltage scenarios, the design removes the unnecessary power conversion hardware that would generate excess heat. The single inverter handles all voltage conversions efficiently, reducing the total heat generation in the system
