Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If device modules are made draw-able for easy maintenance, then ease of operation is improved, but heat dissipation efficiency deteriorates when modules are pulled out
Solution Approach 1:
The patent applies dynamics by making the cooling system adaptive rather than static. The BMC controller dynamically adjusts fan operation modes based on real-time position detection of device modules. When modules are pulled out, the system transitions from normal cooling mode to enhanced cooling mode, ensuring heat dissipation efficiency is maintained despite the structural change in module positioning.
Solution Approach 2:
The patent implements feedback through the position detection mechanism using infrared induction modules. The system continuously monitors whether device modules are in their installed or pulled-out positions and feeds this information back to the BMC controller, which then adjusts fan operation accordingly. This closed-loop feedback ensures that heat dissipation efficiency is maintained regardless of module position.
2Ease of operation
If device modules are pulled out for testing, then ease of operation is improved, but temperature control deteriorates leading to overheating
Solution Approach 1:
The patent applies preliminary action by proactively detecting when device modules are pulled out before overheating occurs. The infrared induction module detects the position change and triggers the BMC controller to switch to enhanced cooling mode in advance, preventing temperature rise before it becomes a problem. This proactive approach maintains temperature control reliability during testing operations.
Solution Approach 2:
The patent implements preliminary anti-action by preparing the cooling system to counteract the potential overheating effect before it occurs. When module removal is detected, the system preemptively increases cooling capacity through fan mode switching, creating a counterbalancing effect that prevents temperature rise and maintains reliability during maintenance operations.
3Temperature
If heat-dissipating fans are positioned for installed modules, then heat dissipation efficiency is improved, but temperature control deteriorates for pulled-out modules
Solution Approach 1:
The patent makes the temperature control system dynamic by enabling it to adapt between different operating conditions. The BMC controller switches between normal cooling mode for installed modules and enhanced cooling mode for pulled-out modules. This dynamic adaptation allows the system to maintain heat dissipation efficiency for installed modules while also providing adequate temperature control for pulled-out modules through fan-directed airflow.
Solution Approach 2:
The patent applies universality by designing a cooling system that serves multiple functions through a single unified approach. The same fan module and control system handle both installed and pulled-out module cooling scenarios, switching between modes as needed. This multi-functional capability eliminates the need for separate cooling systems for different module positions while maintaining temperature control effectiveness in both scenarios.
