Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent replaces manual mechanical arrangement of heat sources with an automated electronic control system. The BMC controller generates driving signals that automatically control the heating module, substituting manual operations with electronic automation. This resolves the contradiction by maintaining ease of implementation through automated control while significantly improving verification reliability through precise power dissipation control.

Inventive Principle:

Solution Approach 2:

The patent implements precise control of heating power dissipation parameters through the driving signal generated by the BMC. By controlling the driving signal parameters (voltage, current, duration), the system can precisely adjust the power dissipation of the heating module to match server heat characteristics. This resolves the contradiction by enabling reliable verification through parameter precision while keeping the system easy to implement through standardized control interfaces.

Solution Approach 2:

The patent introduces the BMC controller and driving signal as intermediary components between the verification system and the heating module. This intermediary layer enables precise control of heat status simulation by mediating between the control logic and the physical heating elements. The intermediary resolves the contradiction by providing precise parameter control while keeping the overall system structure manageable and not excessively complex.
