Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multilayer capacitors lack thermal stability, requiring separate cooling devices, which increases costs, and existing assembly processes are complex and costly, leading to instability due to elongated shapes from unidirectional stacking.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrolytic capacitors or film capacitors are used to achieve high capacitance and high voltage resistance, then thermal stability is poor requiring separate cooling devices, but using thermally stable multilayer capacitors increases the cost of the multilayer capacitor itself
Solution Approach 1:
The product is segmented into multiple individual multilayer capacitors that are stacked together, allowing each capacitor to maintain its own thermal characteristics while collectively achieving the desired performance. This segmentation enables the use of thermally stable multilayer capacitors without requiring a single large expensive component.
Solution Approach 2:
Multiple multilayer capacitors are merged into a single stacked structure, combining their individual thermal stability advantages while achieving high capacitance and voltage resistance collectively. This merging eliminates the need for separate cooling devices while maintaining cost-effectiveness through the use of standard multilayer capacitor components.
2Reliability
If multiple multilayer capacitors are attached to each other to achieve high capacitance and thermal stability, then cooling devices can be omitted, but the assembly process becomes complex and costly
Solution Approach 1:
A frame structure is introduced as an intermediary component to simplify the assembly of multiple multilayer capacitors. The frame provides a standardized mounting platform with extension portions that facilitate easy attachment and alignment of the capacitors, reducing assembly complexity while maintaining thermal stability.
Solution Approach 2:
The frame structure serves multiple functions: it provides mechanical support, enables thermal management through its design, facilitates electrical connections, and simplifies the attachment process. This multi-functionality reduces the need for separate assembly components and procedures, thereby reducing overall assembly complexity.
3Ease of manufacture
If multilayer capacitors are stacked in a single direction to simplify assembly, then the product becomes entirely elongated in one direction, but this deteriorates stability
Solution Approach 1:
The frame structure is designed with asymmetric extension portions that extend in multiple directions rather than a single direction. This asymmetric design allows capacitors to be arranged in a balanced configuration, improving product stability while maintaining assembly simplicity through the standardized frame interface.
Solution Approach 2:
The capacitor stacking is extended from a single linear dimension to multiple dimensions through the frame's extension portions. This dimensional expansion allows capacitors to be arranged in a two-dimensional pattern on the frame, achieving both assembly simplicity and improved product stability through better weight and stress distribution.
