Electrochemical Stack Assembly with Movable Enclosure Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrochemical stack systems require changing the specifications of bus bars and terminal blocks whenever the number of stacked cells is altered, leading to inconvenience and increased production costs.
Innovation Solution
An electrochemical stack assembly design that allows a single specification for bus bars and terminal blocks by using an enclosure and enclosure cover with adjustable fastening members, enabling the enclosure cover to move relative to the enclosure, thus accommodating varying numbers of cells without needing new bus bar and terminal block specifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of stacked cells is changed, then the electrochemical stack configuration is modified, but the bus bar and terminal block specifications must be changed accordingly
Solution Approach 1:
The enclosure cover is designed with a movable structure that can accommodate different numbers of cells using the same bus bar and terminal block specifications. The cover includes a movable portion that shifts position based on cell quantity, allowing a single universal design to serve multiple configurations without requiring separate specifications for each cell number.
Solution Approach 2:
The enclosure cover incorporates a movable portion that can dynamically adjust its position along the enclosure in the stacking direction. This dynamic adjustment allows the same bus bar and terminal block to be used with varying numbers of cells, as the movable cover portion compensates for changes in stack height and positioning requirements.
2Power
If the number of stacked cells is increased, then the power output is improved, but new bus bar and terminal block specifications are required
Solution Approach 1:
The movable enclosure cover design enables a single set of bus bar and terminal block specifications to serve multiple power levels by accommodating different cell quantities. This universality simplifies manufacturing processes and inventory management while still allowing the system to scale power output by simply adding or removing cells.
3Reliability
If the bus bar and terminal block specifications are changed for each cell configuration, then the electrical connection is optimized, but the production cost increases
Solution Approach 1:
The movable enclosure cover creates a universal mounting structure that maintains reliable electrical connections across different cell configurations using the same bus bar and terminal block specifications. This eliminates the need to manufacture and inventory multiple specification variants, thereby reducing production costs while preserving connection reliability.
