Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the power supply circuit is turned off after projector operation, then energy consumption is reduced, but the heat dissipation device stops functioning causing remaining heat to damage the projector
Solution Approach 1:
The rechargeable cell is charged during the projector's normal operation when power is available, storing energy in advance for the post-power-off cooling phase. This preliminary energy storage enables the heat dissipation device to continue functioning after the main power is cut off, resolving the contradiction between energy conservation and continuous heat management.
Solution Approach 2:
The system ensures continuous heat dissipation operation by transitioning from mains power to rechargeable cell power seamlessly when the power supply is turned off. The heat dissipation device maintains its cooling function throughout the entire operation cycle including the post-power-off period, preventing thermal damage while managing energy consumption efficiently.
2Reliability
If the heat dissipation device operates continuously after power off, then remaining heat is effectively dissipated, but additional power is required from the power supply circuit
Solution Approach 1:
The rechargeable cell accumulates electrical energy during the projector's operational phase when the power supply is active. This pre-stored energy is then utilized to power the heat dissipation device after the main power is turned off, enabling continued heat dissipation without requiring additional power from the external power supply circuit.
3Reliability
If a rechargeable cell is added to power the heat dissipation device after power off, then heat dissipation continues extending service life, but device complexity increases
Solution Approach 1:
The rechargeable cell serves multiple functions: it acts as an energy storage device during normal operation and as a power source for the heat dissipation device after power off. This multi-functionality allows a single component to address both operational and post-operational heat management needs, reducing the need for separate dedicated systems and thereby limiting the increase in overall device complexity.
