Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If dual CPU arrangement is adopted to achieve high performance, then processing capability is improved, but chassis length and heat dissipation performance deteriorate
Solution Approach 1:
The controller module is divided into multiple independent functional modules (CPU module, memory module, storage module, interface module) that can be independently selected and arranged. This segmentation allows the system to achieve high processing capability through modular configuration without requiring a longer chassis to accommodate dual CPU arrangements, as the functional modules can be efficiently packed in the available space.
2Power
If dual CPU arrangement is adopted to achieve high performance, then processing capability is improved, but heat dissipation performance deteriorates
Solution Approach 1:
Different functional modules are positioned to optimize heat dissipation characteristics. The controller module with high-power components is placed in the rear end area with direct airflow access, while heat-generating components are arranged to utilize natural convection currents. The middle board design facilitates targeted cooling paths, allowing efficient heat removal without requiring the extended chassis length that would be needed for dual CPU configurations.
3Productivity
If modules are densely packed to maximize space utilization, then cost-effectiveness is improved, but module versatility deteriorates
Solution Approach 1:
The controller module employs standardized functional modules (CPU module, memory module, storage module, interface module) that can be independently selected and configured. This universal module design allows the same chassis structure to accommodate various functional configurations while maintaining dense packing. The middle board provides standardized interfaces that enable versatile module combinations without compromising space efficiency, as each module type serves multiple potential functions depending on the application requirements.
