Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate power supply designs are used for different voltage regions, then compatibility with regional mains power standards is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The power supply system is designed to provide multiple output voltages (110V and 220V AC) using a single unified architecture. The energy storage modules can be configured in different series/parallel arrangements to generate different voltages, eliminating the need for separate power supply designs for different regions and reducing device complexity.
Solution Approach 2:
The system dynamically reconfigures the energy storage modules between series and parallel connections based on the required output voltage. Switching elements enable real-time transformation of the module configuration, allowing the same hardware to adapt to different voltage requirements without physical changes or additional components.
2Adaptability or versatility
If energy storage modules are reconfigured between series and parallel connections, then output voltage adjustability is improved, but switching complexity and potential interruptions increase
Solution Approach 1:
The switching elements are pre-configured in the circuit architecture, with all necessary switches and connections prepared in advance. This allows rapid reconfiguration of the energy storage modules without complex real-time decision-making or additional switching components, reducing switching complexity while maintaining output voltage adjustability.
3Reliability
If a coupled choke is added to manage magnetic flux and loop currents, then power supply stability is improved, but device complexity and component count increase
Solution Approach 1:
The coupled choke integrates two functions into a single component: managing magnetic flux from the switching operations and limiting loop currents between parallel energy storage modules. This merged design provides enhanced stability without proportionally increasing device complexity, as one component performs multiple critical functions.

AI summary
An electrical system with selectable output voltage is disclosed. An example system includes a first set of energy storage modules, a second set of energy storage modules, a choke connected to the first set of energy storage modules and the second set of energy storage modules, and a switch configured to switch between a first state and a second state. Upon switching the switch to the first state, the first set of energy storage modules are connected in parallel with the second set of energy storage modules to provide a first voltage to at least one output. Upon switching the switch to the second state, the first set of energy storage modules are connected in series with the second set of energy storage modules to provide a second voltage to the at least one output.
