Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the capacitors have small capacitance, then the size and cost are reduced, but the battery is fully charged in a moment and part of the generated electric power is wasted
Solution Approach 1:
The patent applies parameter changes by determining the optimal capacitance value based on specific parameters including the duration of power generating action, electromotive force, and internal resistance of the power generating device. By calculating and setting the capacitance to an energy-maximizing value rather than using fixed small or large values, the system achieves optimal energy storage efficiency while avoiding waste and excessive size/cost
2Loss of energy
If the capacitance is not optimized, then the system is simpler to design, but energy waste increases and system performance deteriorates
Solution Approach 1:
The patent applies feedback by using the actual operating parameters of the power generating device (duration of action, electromotive force, internal resistance) to determine the optimal capacitance value. This feedback-based determination ensures energy efficiency is optimized based on real system characteristics without requiring complex iterative design processes
