Battery Stack Plate Sealing Groove for Faster Module Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing board-shaped member designs for battery stacks require direct application of sealing material to the front and back faces of battery stack plates, which is time-consuming and inefficient.
Innovation Solution
A board-shaped member with a recessed fitting groove and a sealing material supply groove, allowing pre-filled sealing material to be extruded onto the faces when the conductive plate is fitted, facilitating easier application of the sealing material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sealing material is directly applied to the front and back faces of battery stack plates, then sealing is achieved, but work time increases and process efficiency decreases
Solution Approach 1:
The sealing material is pre-filled into the fitting groove before assembly, so that when the conductive plate is fitted into the groove, the sealing material is automatically extruded to the front and back faces. This preliminary preparation eliminates the need for separate sealing material application steps during assembly, reducing work time while ensuring reliable sealing.
2Ease of manufacture
If sealing material is pre-filled into the fitting groove, then sealing material application becomes easier and faster, but the board-shaped member structure becomes more complex
Solution Approach 1:
The board-shaped member is divided into distinct functional components: the insulating housing, the fitting groove, the sealing material supply groove, and the through hole. This segmentation allows the sealing material to be pre-filled into the fitting groove as a separate preparation step, simplifying the assembly process while the modular structure manages the added complexity in an organized manner.
3Temperature
If cooling air flows efficiently into the cooling passage, then cooling performance improves, but gaps between board faces must be filled with sealing material
Solution Approach 1:
The fitting groove serves multiple functions: it provides the sealing interface for the conductive plate, acts as a supply channel for the sealing material, and ensures proper positioning of components. By making the groove multi-functional, the design addresses the cooling air flow requirement while managing the gap filling need through the same structural feature, reducing overall device complexity.
