Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If passive cooling is used, then power consumption is reduced, but heat removal effectiveness is insufficient
Solution Approach 1:
The patent employs a pendulum assembly that oscillates mechanically to generate air flow for cooling. The pendulum's periodic motion creates convection currents that enhance heat removal from electronic components without requiring electrical power, thus resolving the contradiction between low power consumption and effective heat removal.
Solution Approach 2:
The cooling system utilizes periodic oscillation of the pendulum assembly to generate intermittent air flow. This periodic action maintains cooling effectiveness while consuming minimal energy, as the system leverages gravitational potential energy conversion during the pendulum's swing cycle rather than continuous electrical power input.
2Reliability
If active cooling is used, then heat removal effectiveness is improved, but power consumption increases
Solution Approach 1:
The pendulum assembly serves itself by converting its own gravitational potential energy into kinetic energy during oscillation, which drives the air flow for cooling. This self-service mechanism eliminates the need for external electrical power input while maintaining effective heat removal, resolving the contradiction between cooling effectiveness and power consumption.
Solution Approach 2:
The patent replaces the typical electrical fan or pump system with a mechanical pendulum-based oscillation system. This substitution uses gravitational potential energy and mechanical motion instead of electrical power to generate the necessary air flow for cooling, thereby reducing power consumption while maintaining heat removal effectiveness.
