Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different power supply protocol management apparatuses are designed for different CPU types, then each CPU can have its specific power supply requirements met, but the device complexity increases and resource wastage occurs due to lack of universality
Solution Approach 1:
The power supply apparatus is designed with a universal interface that can work with different CPU types through protocol identification and adaptation. The system automatically detects the CPU type and selects appropriate control parameters, allowing one power supply apparatus to serve multiple CPU models without requiring separate dedicated designs for each CPU type.
Solution Approach 2:
A protocol identification and conversion module is introduced as an intermediary between the power supply apparatus and the CPU. This module detects the CPU type, identifies the appropriate VID protocol, and converts control signals accordingly, enabling compatibility between different CPU types and power supply apparatuses without requiring each CPU to have a dedicated power supply design.
2Reliability
If separate power supply circuits are designed for different power supply protocol management apparatuses, then each device can operate optimally, but resource wastage increases due to multiple incompatible power supplies in the market
Solution Approach 1:
The power supply apparatus incorporates a universal design that can adapt to different CPU types through automated protocol detection and parameter adjustment. This eliminates the need for multiple incompatible power supply models, allowing consumers to use a single power supply apparatus across different CPU generations and types, thereby reducing resource wastage while maintaining optimal performance for each specific CPU.
Solution Approach 2:
The system dynamically adjusts power supply parameters based on the detected CPU type and VID protocol. By changing control parameters rather than hardware architecture, the same physical power supply apparatus can deliver optimal performance to different CPU types, eliminating the need for separate power supply circuits for each CPU model.
3Manufacturing precision
If each CPU type has a dedicated power supply protocol management apparatus, then power supply control precision is optimized for each CPU, but the ease of operation decreases due to incompatibility issues
Solution Approach 1:
A protocol conversion module serves as an intermediary that automatically detects the CPU type and translates control signals into the appropriate VID protocol format. This eliminates the need for users to manually configure or select power supply apparatuses for different CPU types, as the system automatically adapts the control parameters while maintaining precise power supply control for each specific CPU.
Solution Approach 2:
The power supply apparatus performs automatic CPU type detection and protocol adaptation without requiring user intervention. The system self-configures the appropriate VID protocol and control parameters based on the connected CPU, making the power supply compatible with different CPU types while maintaining optimal control accuracy, thereby simplifying operation for end users.

AI summary
A power supply system includes a PWM power supply connected to and supplying power to a power-consuming unit and a power supply protocol management apparatus connected to the power-consuming unit through a transmission bus for acquiring a VID protocol of the power-consuming unit and acquiring a VID code conversion table matching the VID protocol. The power supply protocol management apparatus converts a VID code output by the power-consuming unit (on the basis of the VID protocol) into a required voltage of the power-consuming unit according to the VID code conversion table, compares the required voltage with a voltage at an output end of the PWM power supply to generate a feedback voltage value, and transmits the generated feedback voltage value to the PWM power supply which adjusts its output voltage according to the feedback voltage value.
