Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wound capacitors in existing technologies are prone to breakage or cracks at the bends of their conductive pins during bending processes.
Innovation Solution
A wound capacitor package structure that includes a pin protection assembly with a first and second pin protection layer covering the exposed portions of the conductive pins, which are either prefabricated or post-production coatings, to prevent breakage or cracking during bending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the conductive pins are bent to achieve desired routing, then the capacitor can be installed in different positions, but the conductive pins are prone to breakage or cracks at the bends
Solution Approach 1:
The pin protection assembly is installed on the conductive pins before the bending operation. This preliminary protective measure ensures that when the pins are subsequently bent for installation, the protected portions remain free from cracks and breakage, resolving the contradiction between bending adaptability and structural integrity
Solution Approach 2:
The pin protection assembly acts as a cushioning layer that is applied beforehand to the conductive pins. This protective layer absorbs and distributes the stress during bending operations, preventing crack formation at critical locations while allowing the pins to be routed and installed in various positions
2Adaptability or versatility
If the conductive pins are made longer to expose more connection points, then more connection options are available, but the exposed portions become more susceptible to damage
Solution Approach 1:
The pin protection assembly is installed on the exposed portions of the conductive pins before they are subjected to handling or installation processes. This preliminary protection allows the pins to be made longer for additional connection options while preventing damage to the extended exposed portions
Solution Approach 2:
The pin protection assembly functions as a flexible protective shell or thin film that covers the exposed portions of the conductive pins. This flexible covering provides durability protection to the extended pin sections while maintaining the necessary adaptability for various connection configurations

AI summary
A wound capacitor package structure includes a wound assembly, a conductive assembly, a package assembly, a bottom seat plate and a pin protection assembly. The conductive assembly includes a first and a second conductive pin. The package assembly is configured for enclosing the wound assembly. The bottom seat plate is disposed on a bottom side of the package assembly. The pin protection assembly includes a first pin protection layer configured to partially cover the first conductive pin, and a second pin protection layer configured to partially cover the second conductive pin. The first conductive pin includes a first exposed portion exposed outside the package assembly, and the second conductive pin includes a second exposed portion exposed outside the package assembly. The first and the second pin protection layer are disposed on the first and the second exposed portion for protecting the first and the second conductive pin, respectively.
