Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If electrostatic loudspeakers are stacked to increase output power, then the power output is improved, but the potential difference among plural sets of electrostatic loudspeakers becomes zero, causing no vibration
Solution Approach 1:
The patent divides the electrostatic loudspeaker into multiple independent stacking units, each consisting of a first electrode, a second electrode, and a vibrating membrane. Each unit maintains its own potential difference and vibration capability, allowing multiple units to be stacked without causing the potential difference to become zero across all units simultaneously.
Solution Approach 2:
The patent introduces a vertical stacking dimension to arrange multiple electrostatic loudspeaker units in series. By connecting the second electrode of one unit to the first electrode of the next unit vertically, the system achieves increased power output while maintaining potential differences through the alternating connection pattern across dimensions.
2Power
If electrostatic loudspeakers are stacked to increase output power, then the power output is improved, but the vibrating membranes between electrodes cannot move due to lack of potential difference
Solution Approach 1:
The patent segments the electrostatic loudspeaker system into discrete units with independent vibrating membranes. Each segment maintains its own electrical potential difference, ensuring that the vibrating membranes can move independently without being constrained by the lack of potential difference in stacked configurations.
Solution Approach 2:
The patent implements dynamic potential difference maintenance through alternating connections in the stacking configuration. The electrical potential differences are dynamically preserved across the vibrating membranes through the series connection pattern, allowing continuous vibration and sound generation even in stacked configurations.
