Detachable Capacitor Connection for Storage Device RMA
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connection methods for capacitors in storage devices, such as direct soldering to a printed circuit board, complicate testing, repair, and replacement in mass production and return merchandise authorization (RMA) operations, as they require reflow and manual rework to remove and replace failed capacitors.
Innovation Solution
A detachable capacitor connection structure is introduced, featuring connection elements like dual in-line package sockets, right angle sockets, headers, and sockets with crimp structures, and connectors with fingers and pin headers, allowing capacitors to be easily connected and disconnected from the circuit board, facilitating easy replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct soldering is used to connect capacitors to the circuit board, then the connection is stable and reliable, but the complexity of testing, repair, and replacement increases significantly
Solution Approach 1:
The connection structure is divided into separate components: a connector mounted on the circuit board and a corresponding socket on the capacitor module. This segmentation allows the capacitor module to be detached and replaced independently without affecting the circuit board, resolving the contradiction between connection stability and repair ease.
Solution Approach 2:
A connector-socket interface acts as an intermediary between the circuit board and the capacitor module. This intermediary provides a reliable electrical connection while enabling easy detachment and replacement, thus maintaining connection stability while dramatically improving ease of repair and replacement.
2Stability of the object's composition
If direct soldering is used to connect capacitors, then the connection is permanent and secure, but manual rework is required for removal and replacement
Solution Approach 1:
The connection system is segmented into a permanent connector mounted on the circuit board and a detachable socket on the capacitor module. The connector provides permanent, secure attachment to the board, while the socket enables quick detachment, eliminating the need for time-consuming soldering rework.
Solution Approach 2:
The connection structure transitions from a static soldered joint to a dynamic detachable interface. The connector-socket mechanism allows the connection to be easily made and broken, reducing the time required for capacitor replacement while maintaining connection security during operation.
3Device complexity
If capacitors are soldered directly to the circuit board, then the structure is simple, but testing and repair operations become complicated
Solution Approach 1:
The connection structure is segmented into a connector on the circuit board and a socket on the capacitor module. This segmentation maintains relative structural simplicity while dramatically improving ease of testing and repair, as the capacitor module can be easily detached and replaced without complex soldering operations.

AI summary
A detachable capacitor connection structure is provided for a storage device. In an embodiment, a connection element detachably connects a capacitor module including one or more capacitors to a circuit board such that the capacitor module is stacked over the circuit board. The connection element includes: a first connector including two pin headers, mounted on a bottom plane of the capacitor module; and a second connector including two sockets, mounted on a top plane of the circuit board corresponding to the bottom of the capacitor module, suitable for connecting the first connector to the circuit board.
