Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-function interface conversion device is used, then the device complexity is reduced, but the adaptability and versatility are insufficient to meet diverse user requirements
Solution Approach 1:
The patent implements multi-functionality by integrating a power adapter module with AC-to-DC conversion capability into an interface conversion device. The device can simultaneously perform interface conversion between different USB standards (Type-C, Type-A, Micro USB) and provide fast charging functionality, allowing one device to serve multiple purposes that previously required separate devices
Solution Approach 2:
The patent merges the power adapter module and interface conversion module into a single integrated device. The power adapter module includes AC-to-DC conversion units and power management units, while the interface conversion module handles different interface protocols, and both are combined in one device to achieve simultaneous power supply and interface conversion capabilities
2Power
If power is supplied during interface conversion, then the power output capability is improved, but the power management complexity increases due to switching between power output and input modes
Solution Approach 1:
The patent implements dynamic power management where the power management unit can dynamically switch between different operational modes: outputting second direct current to the first interface for fast charging, or pulling third direct current from the first interface to power the interface conversion module. This dynamic switching capability allows the device to adapt its power flow direction based on operational requirements
Solution Approach 2:
The device can self-power the interface conversion module by pulling current from the first interface when the power output terminal is not actively charging, eliminating the need for separate power supply circuits for the conversion module itself. This self-service approach reduces overall system complexity
