Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple feedthrough multilayer capacitors are loaded to achieve parallel capacitance connections, then the required capacitance value can be obtained, but the mount space in the electronic device increases
Solution Approach 1:
The patent combines multiple capacitance components into a single feedthrough multilayer capacitor by integrating multiple internal electrode groups within one capacitor element body. Each internal electrode group forms a separate capacitance component, and these components are connected in parallel through throughhole conductors, achieving the desired total capacitance value while occupying only one mounting position instead of multiple positions.
Solution Approach 2:
The patent nests multiple internal electrode groups within a single capacitor element body. Each internal electrode group consists of signal internal electrodes and ground internal electrodes arranged in specific layers, with these groups nested concentrically or adjacently within the same dielectric structure, allowing multiple capacitance components to coexist in a compact configuration.
2Quantity of substance
If multiple internal electrode groups are arranged to create separate capacitance components, then parallel connection is achieved, but the number of layers increases
Solution Approach 1:
The patent transitions from a vertical stacking arrangement to a radial or planar arrangement of internal electrode groups. Instead of placing electrode groups in separate layers along the vertical axis, the patent arranges multiple signal internal electrodes and ground internal electrodes in different radial positions or adjacent regions within the same layers, connected through throughhole conductors that extend vertically, thereby reducing the number of layers required.
Solution Approach 2:
The patent segments the capacitor element body into multiple internal electrode groups, each comprising signal internal electrodes and ground internal electrodes. These segmented groups are distributed across different regions of the capacitor element body and connected through throughhole conductors, allowing the capacitance components to be arranged in a space-efficient manner that minimizes the number of layers.
3Adaptability or versatility
If throughhole conductors are used to connect internal electrodes, then parallel circuit implementation is achieved, but the manufacturing complexity increases
Solution Approach 1:
The patent incorporates throughhole conductors as integral parts of the capacitor element body structure during the manufacturing process. The throughhole conductors are formed by punching holes through the dielectric layers and filling them with conductive material before the final sintering process, allowing the parallel circuit connections to be established automatically during manufacturing without requiring additional post-assembly steps.
Solution Approach 2:
The throughhole conductors serve dual functions: they provide mechanical support for the internal electrodes and simultaneously establish the electrical connections required for parallel circuit configuration. The conductors are positioned and sized to automatically connect the corresponding internal electrodes from different groups, eliminating the need for separate connection processes and reducing manufacturing complexity.
