Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a conventional air guiding lid is used to guide air flow toward high-heat-generating chip modules, then heat dissipation at specific locations is improved, but the system cannot adapt to dynamic temperature variations at different locations
Solution Approach 1:
The patent applies the dynamics principle by making the air guiding lid movable and adjustable. The lid can dynamically change its position and orientation to redirect air flow toward different chip modules based on real-time temperature conditions, enabling the system to adapt to varying thermal patterns across the mainboard
Solution Approach 2:
The patent implements feedback by using temperature sensors to monitor thermal conditions at different locations and automatically adjusting the air guiding lid's position in response to detected temperature variations, creating a closed-loop control system that adapts to changing thermal requirements
2Productivity
If chip modules are densely packed to meet complex layout requirements, then computing capability is improved, but heat dissipation becomes insufficient at various locations
Solution Approach 1:
The patent applies segmentation by dividing the air flow control into multiple independent adjustable sections along the air guiding lid, allowing each section to be independently positioned to target specific heat-generating chip modules, thereby enabling precise heat dissipation control for densely packed components
Solution Approach 2:
The patent implements local quality by enabling different regions of the mainboard to receive customized air flow based on their specific thermal requirements, with the adjustable lid directing cooling air to locations with highest heat generation rather than distributing it uniformly
