Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If continuous operation is maintained to improve productivity, then productivity increases, but temperature rises causing reliability to deteriorate
Solution Approach 1:
The control circuit proactively activates the cooling fan before temperature reaches critical levels by detecting temperature increases during continuous operation. This preliminary cooling action prevents temperature-related defects before they occur, allowing continuous operation to maintain both productivity and reliability
2Temperature
If external cooling techniques are used to reduce temperature, then temperature control improves, but temperature sensing accuracy deteriorates
Solution Approach 1:
A transparent heat dissipation plate is introduced as an intermediary between the storage device and cooling fan. This plate allows accurate temperature sensing through its transparent structure while simultaneously enabling effective heat dissipation, thus maintaining both temperature control and sensing accuracy
3Reliability
If cooling fan is always operated to maintain temperature, then reliability improves, but energy consumption increases
Solution Approach 1:
The cooling fan operates dynamically based on real-time temperature conditions detected by the control circuit. The fan speed and operation mode are adjusted according to current temperature levels, ensuring reliable cooling when needed while minimizing energy consumption during normal operation
