1Quantity of substance
If internal electrodes are arranged to overlap and form multiple electrical functional units, then integration density is improved, but edge effects between electrodes increase
Solution Approach 1:
The patent introduces a third dimension by having electrodes extend from side surfaces in addition to end surfaces. Multiple internal electrodes (first, second, third, and fourth electrodes) are arranged to overlap in three-dimensional space, creating multiple electrical functional units within the same component volume. This dimensional approach increases integration density while the specific geometric arrangement minimizes edge effects between adjacent electrodes.
Solution Approach 2:
The component is segmented into multiple independent electrical functional units, each formed by specific combinations of internal electrodes and ceramic layers. The first electrical functional unit is formed by first and second internal electrodes, while the second electrical functional unit is formed by third internal electrode overlapping with first and second electrodes. This segmentation allows independent functionality of each unit while maintaining compact integration.
2Adaptability or versatility
If multiple internal electrodes are arranged to form independent functional units, then functional independence is improved, but device complexity increases
Solution Approach 1:
The internal electrodes serve multiple functions simultaneously. The first and second internal electrodes form the first electrical functional unit, while the third internal electrode overlaps with both to form the second electrical functional unit. This multi-functionality allows a single electrode structure to create multiple independent functional units, reducing overall device complexity while maintaining functional independence.
Solution Approach 2:
The electrode arrangement follows a nested structure where the third internal electrode overlaps with both first and second internal electrodes, creating a hierarchical arrangement. The fourth internal electrode similarly overlaps with first and second electrodes to create additional functional units. This nesting approach allows multiple functional units to be packed efficiently within the component volume without requiring completely separate electrode structures for each unit.
