Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual cleaning of air pathways is performed, then cleaning effectiveness is improved, but maintenance cost and time increase significantly
Solution Approach 1:
The system employs an automated cleaning mechanism that uses a spray nozzle to inject cleaning fluid into the air pathways through the heat exchanger, enabling the display apparatus to clean itself without manual intervention. This self-service approach maintains cleaning effectiveness while eliminating the time-consuming manual maintenance process.
2Reliability
If manual cleaning operation is performed, then cleaning effectiveness is improved, but safety risks increase when installed at high positions
Solution Approach 1:
The automated cleaning system eliminates the need for personnel to manually access or clean the air pathways at high installations. The spray nozzle automatically delivers cleaning fluid through the heat exchanger, removing the safety hazards associated with manual operations at elevated positions while maintaining effective cleaning.
3Temperature
If frequent maintenance is performed, then heat dissipation efficiency is maintained, but operational time is reduced
Solution Approach 1:
The system performs cleaning actions automatically and periodically without requiring operational interruptions. By pre-scheduling maintenance operations during off-peak times or using rapid automated cleaning cycles, the heat dissipation efficiency is maintained while minimizing the impact on operational duration.
4Extent of automation
If cleaning device is added to the system, then automated cleaning capability is improved, but device complexity increases
Solution Approach 1:
The heat exchanger serves dual functions: it facilitates heat dissipation from the display apparatus and simultaneously acts as a conduit for delivering cleaning fluid to the air pathways. This multi-functionality reduces the need for separate dedicated cleaning components, thereby limiting the increase in device complexity while achieving automated cleaning capability.
