1Length of stationary object
If electrodes are arranged in vertical stacking direction, then structural stability is maintained, but thickness reduction is limited
Solution Approach 1:
The patent transitions from vertical stacking arrangement to horizontal arrangement of electrodes, changing the spatial dimension of electrode configuration. This allows the capacitor to reduce thickness in the vertical direction while maintaining effective electrode area and structural integrity through the horizontal layout with complementary patterns.
2Productivity
If electrode area is increased to improve reaction efficiency, then volume increases, but device size reduction is constrained
Solution Approach 1:
By arranging electrodes horizontally with complementary patterns, the patent increases the effective reaction area within the same volume by utilizing horizontal space more efficiently. The complementary pattern design allows electrodes to interlock or interdigitate, maximizing the interface area for electrochemical reactions without increasing the overall volume of the capacitor.
Solution Approach 2:
The complementary pattern configuration allows one electrode structure to nest within or interdigitate with the other electrode structure, effectively increasing the reaction interface area within a compact volume. This nested arrangement enables more reaction points to be packed into the same space, improving reaction efficiency without volume expansion.
3Productivity
If complementary pattern is implemented to increase reaction area, then manufacturing complexity increases, but reaction efficiency improves
Solution Approach 1:
The complementary pattern divides each electrode into multiple segments or regions that interlock with the other electrode. This segmentation increases the reaction area by creating multiple interfaces, while the modular nature of the segmented design can simplify manufacturing by allowing standardization of the repeating pattern units.
