Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual control of heat dissipation device is implemented, then heat dissipation function is achieved, but user experience deteriorates due to requiring manual operation
Solution Approach 1:
The heat dissipation device automatically detects when the display apparatus is placed on it and activates heat dissipation without requiring manual user intervention. The system serves itself by using the presence of the display apparatus as the trigger condition, eliminating the need for users to manually control the heat dissipation function.
Solution Approach 2:
The patent replaces manual mechanical control (user pressing a switch) with an automatic detection mechanism that senses the weight or presence of the display apparatus. This substitution eliminates the need for manual operation while maintaining the heat dissipation function.
2Reliability
If heat dissipation device is always on, then overheating is prevented, but energy consumption increases
Solution Approach 1:
The heat dissipation device operates periodically rather than continuously - it activates only when the display apparatus is detected on the device and deactivates when removed. This periodic operation ensures overheating prevention is maintained during use while minimizing energy consumption during non-use periods.
Solution Approach 2:
The system uses feedback from weight sensors or presence detection to control heat dissipation activation. When the display apparatus is detected (feedback signal), heat dissipation activates; when removed (feedback signal changes), it deactivates. This feedback mechanism ensures reliability only when needed, optimizing energy consumption.
3Extent of automation
If automatic weight-based control is implemented, then automation is improved, but device complexity increases
Solution Approach 1:
The patent extracts the control logic from manual user action and embeds it in an automatic weight-based detection system. By separating the detection function (weight sensing) from the execution function (heat dissipation activation), the system achieves automation while keeping each component relatively simple.
Solution Approach 2:
The weight detection mechanism serves multiple purposes: it detects the presence of the display apparatus, triggers heat dissipation activation, and can potentially control other functions. This multi-functionality reduces the need for separate control mechanisms, managing complexity while maintaining automation.
