Energy Storage End Cover Terminal for Sealed External Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In energy storing apparatuses, the electrode cannot be directly led out for external electrical connection due to its integration within the housing, making it difficult to form a connection with external circuits.
Innovation Solution
The design includes a metal part with a protruding boss on the end cover, allowing the electrode to be electrically connected to the metal part and led out for external connection, facilitated by an insulating seal to prevent short circuits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the electrode is integrated within the housing, then the structural integrity is improved, but the ease of electrical connection to external circuits deteriorates
Solution Approach 1:
The patent extracts the electrical connection function from the housing structure by introducing a separate metal part with a protruding boss. This boss extends through the end cover to provide an external electrical connection point, while the housing maintains its integrated structure for structural integrity.
Solution Approach 2:
The metal part with the protruding boss serves as an intermediary element between the internal electrode and the external circuit. It provides a bridge for electrical connection without compromising the housing's structural integrity, as it connects to the electrode internally while extending externally through the end cover.
2Ease of operation
If a metal part with protruding boss is added, then the ease of electrical connection is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple functions into the metal part: it serves as both the electrical conductor and the structural support for the protruding boss. The end cover integrates the second opening and the insulating seal, combining sealing and electrical isolation functions in a single component.
Solution Approach 2:
The metal part performs multiple functions: it provides electrical connection, structural support for the protruding boss, and mounting surface for the insulating seal. The end cover also serves multiple purposes: sealing the housing, providing the second opening, and supporting the metal part assembly.
3Reliability
If an insulating seal is provided between the metal part and end cover, then the reliability is improved, but the manufacturing complexity increases
Solution Approach 1:
The insulating seal is implemented as a thin film or gasket that can be easily installed between the metal part and the end cover. This flexible sealing element provides reliable electrical insulation and sealing without requiring complex manufacturing processes or assembly steps.
