Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If an electrolytic capacitor is used as a power supply for flash memory, then the device structure is simple and manufacturing is easy, but the power supply capability is insufficient for large-capacity flash memory
Solution Approach 1:
The patent changes the chemical composition parameters of the electrolyte solution, specifically using propylene carbonate with 80 volume % or greater content. This parameter change enables the electric double layer capacitor to achieve high power supply capability (capacitance of 1000 μF or more) while maintaining a compact structure suitable for solid state drives.
Solution Approach 2:
The patent employs composite material design by combining propylene carbonate as the primary solvent with specific electrolytes (such as LiClO4, LiBF4, or LiPF6) to create an electrolyte solution that delivers superior power supply performance. This composite approach enables the capacitor to meet the high power demands of large-capacity flash memory.
2Quantity of substance
If the flash memory capacity is increased to store more data, then the storage capability is improved, but the power supply requirement increases beyond what conventional electrolytic capacitors can provide
Solution Approach 1:
By changing the electrolyte composition to use propylene carbonate (80 volume % or greater), the patent achieves high capacitance values (1000 μF or more) that can supply sufficient power to large-capacity flash memory devices, thereby enabling increased data storage capacity without power supply limitations.
3Reliability
If conventional electrolytic capacitors are used, then the device is compact and easy to manufacture, but the durability and heat resistance are insufficient
Solution Approach 1:
The patent improves durability and heat resistance by changing the electrolyte composition to use propylene carbonate, which has superior thermal stability compared to conventional electrolytes. This chemical parameter change enhances the capacitor's reliability under high-temperature conditions while maintaining manufacturing feasibility through standard electric double layer capacitor fabrication processes.
