Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional heat dissipation methods (fan, duct, Peltier device, heat pipe) are used, then heat dissipation effectiveness is improved, but device complexity and maintenance requirements increase
Solution Approach 1:
The patent extracts the heat dissipation function from complex active cooling systems (fans, Peltier devices, heat pipes) and implements it through a passive fin structure that utilizes natural convection, thereby simplifying the overall device architecture while maintaining effective heat dissipation
Solution Approach 2:
The fin structure performs heat dissipation autonomously through natural convection currents generated by temperature differences, without requiring external power sources or control systems, making the system self-regulating and maintenance-free
2Temperature
If conventional heat dissipation methods are used, then heat dissipation effectiveness is improved, but apparatus size increases
Solution Approach 1:
The fin structure extends the heat dissipation surface into the third dimension by creating multiple parallel surfaces that increase total heat exchange area without proportionally increasing the device's external volume, allowing efficient heat dissipation in a compact form factor
3Measurement precision
If high frame rate image capture is performed, then detection accuracy is improved, but temperature of the camera increases
Solution Approach 1:
The patent converts the harmful effect of high frame rate operation (heat generation) into a beneficial driving force for natural convection, where the temperature difference created by intensive operation automatically enhances heat dissipation through buoyancy-driven air flow, allowing sustained high-performance operation without thermal degradation
