Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If voltage lowering and/or rectifying circuit is used to process power from city power or batteries, then power can be provided to electronic components, but a large amount of heat is generated causing the memory storage device to overheat
Solution Approach 1:
The power supply system is segmented into multiple independent voltage regulation modules, each responsible for specific voltage levels (e.g., 3.3V, 1.8V, 1.2V). This segmentation distributes the power processing load across multiple stages, reducing heat concentration in a single circuit and improving thermal management while maintaining efficient power conversion.
Solution Approach 2:
Different voltage regulation techniques are applied to different parts of the system based on local requirements. High-current paths use low-dropout regulators for efficiency, while low-current paths use switching regulators for better voltage conversion ratios. This localized optimization reduces overall heat generation while meeting specific power needs of different components.
2Adaptability or versatility
If larger voltage adjustment is made by voltage lowering circuit, then power voltage can be adapted to different components, but heat generation increases
Solution Approach 1:
The system employs dynamic voltage scaling capabilities where voltage levels are adjusted in real-time based on operational requirements. Multiple voltage rails (3.3V, 1.8V, 1.2V) can be dynamically enabled or disabled, and voltage levels can be adjusted according to workload demands, optimizing energy efficiency while maintaining adaptability to different component requirements.
Solution Approach 2:
The invention changes the operating parameters of the power supply system by introducing multiple discrete voltage levels instead of a single adjustable voltage. This allows each voltage level to be optimized for specific functions (e.g., 3.3V for I/O, 1.8V for logic, 1.2V for high-performance cores), reducing energy loss while maintaining versatility through parameter diversification.
3Reliability
If conventional voltage conversion method is used, then power can be supplied to components, but heat radiation increases reducing performance
Solution Approach 1:
The invention introduces intermediate voltage buffering stages between the power input and final component supply. Power is converted to intermediate voltage levels first, then distributed to various components through regulated pathways. This intermediary approach stabilizes power delivery while distributing thermal load, preventing excessive heat radiation and maintaining operational reliability.
Solution Approach 2:
The system replaces traditional linear voltage regulation (which generates significant heat) with switching regulation technology. This substitution uses electromagnetic field-based energy transfer instead of resistive voltage dropping, dramatically reducing heat radiation while maintaining stable power supply and improving overall system reliability.
