Engineering Contradiction Analysis
1Duration of action of moving object
If conventional tablets are used for prolonged aviation operations, then navigation and communication functions are maintained, but overheating occurs leading to malfunction
Solution Approach 1:
The cooling system is divided into separate functional modules: active cooling components (Peltier coolers, fans) and passive cooling components (heat sinks, copper plate, liquid circulation system). This segmentation allows each component to perform its specific cooling function efficiently while working together to maintain tablet temperature during prolonged operations.
Solution Approach 2:
The cooling apparatus is positioned and activated before the tablet reaches critical temperature levels. The system proactively manages heat accumulation by continuously or periodically activating cooling mechanisms, preventing overheating before it causes malfunction and extending safe operational duration.
2Temperature
If active cooling components (fans, Peltier coolers) are added to the tablet cooling system, then cooling effectiveness is improved, but device complexity increases
Solution Approach 1:
Multiple cooling technologies (active Peltier cooling, active fan-driven air cooling, passive heat sink conduction, and passive liquid circulation) are merged into a single integrated cooling apparatus. This combination allows the system to leverage the strengths of each cooling method while managing complexity through unified design and control.
Solution Approach 2:
The cooling system incorporates self-regulating elements such as heat sinks that passively dissipate heat through conduction and convection without requiring external control, and liquid circulation that utilizes natural convection currents. These self-service mechanisms reduce the burden on active components and simplify overall system control.
3Temperature
If multiple cooling mechanisms are integrated into the tablet cooling apparatus, then temperature regulation is improved, but manufacturing complexity increases
Solution Approach 1:
The cooling apparatus is designed as a multi-functional unit that can cool different tablet models and configurations. The modular design with standardized components (copper plate, heat sinks, Peltier coolers, fans) allows the same basic apparatus to be adapted for various tablet sizes and heat generation patterns, simplifying manufacturing by using common parts across different applications.
