Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single power supply is used to simplify the power supply system, then device complexity is reduced, but the ability to supply various voltages to different electronic components is limited
Solution Approach 1:
The power supply system is segmented into multiple independent power supply units, each dedicated to supplying power to specific electronic components. This segmentation allows each unit to be optimized for its specific voltage requirements while maintaining overall system manageability through modular architecture.
Solution Approach 2:
The power supply system is designed with multi-functionality to supply various voltages (e.g., 3.3V, 5V, 12V) through a unified power management architecture. This universal power supply capability allows a single system to serve multiple different voltage requirements of various electronic components simultaneously.
2Adaptability or versatility
If multiple power supplies are added to supply various voltages, then adaptability to different electronic components is improved, but device complexity increases
Solution Approach 1:
Multiple power supply units are nested within a hierarchical power management structure, where higher-level power management controllers coordinate lower-level voltage regulation modules. This nesting approach allows complex multi-voltage supply capabilities to be organized in a manageable hierarchical framework.
Solution Approach 2:
Power management integrated circuits (PMICs) and voltage regulators serve as intermediary components between the main power source and various electronic components. These intermediaries simplify the interface between multiple power supplies and different voltage requirements, reducing overall system complexity.
3Adaptability or versatility
If voltage conversion circuits are added to provide various voltages, then functionality of the aerosol generation device is improved, but loss of energy increases
Solution Approach 1:
The system dynamically changes voltage parameters based on the specific requirements of different electronic components and operational modes. By optimizing voltage levels in real-time rather than using fixed voltage conversion ratios, energy loss during voltage conversion is minimized while maintaining full functionality.
Solution Approach 2:
Voltage conversion operations are performed periodically and on-demand rather than continuously, activating voltage conversion circuits only when specific voltage requirements arise. This periodic operation reduces unnecessary energy loss in voltage conversion while ensuring functionality is maintained when needed.
