Battery Cell Stack Mounting Using Film Guidance Without Frame Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in mounting a battery cell stack to a frame without deforming or distorting the frame, while also preventing space utilization deterioration and ensuring the battery cell stack is not damaged during the process.
Innovation Solution
An apparatus and method utilizing a support member, roller member, film guide member, and pressing member to guide the battery cell stack into the frame along a film, allowing it to be mounted without deformation or damage, and incorporating a film damage prevention member to prevent film tearing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery cell stack is inserted into the U-shaped frame by deforming the side cover outward, then the battery cell stack can be mounted to the frame, but the frame may be permanently deformed and distorted
Solution Approach 1:
A guide member is introduced as an intermediary component between the battery cell stack and the U-shaped frame. The guide member has a guide groove that receives the battery cell stack and guides it into the frame, while the guide protrusion on the side cover interacts with the guide groove to control the insertion process. This intermediary structure enables mounting without directly deforming the frame's side covers, thus resolving the contradiction between mounting ease and frame shape stability.
2Ease of operation
If a predetermined space is formed between the U-shaped frame and the battery cell stack to facilitate mounting, then the battery cell stack can be easily mounted, but the space utilization of the battery module decreases and the total volume increases
Solution Approach 1:
The side cover is pre-deformed to an intermediate state where the guide protrusion is positioned to engage with the guide groove, but the side cover is not fully spread outward. This preliminary positioning allows the battery cell stack to be guided into the frame along the guide groove without requiring excessive clearance. The space is optimized by only creating the minimum necessary gap for the guide mechanism to function, thereby resolving the contradiction between mounting ease and volume efficiency.
3Volume of moving object
If the inner length of the U-shaped frame is made identical or extremely similar to the entire length of the battery cell stack, then space utilization is maximized, but there is substantially no clearance for mounting
Solution Approach 1:
The solution moves the mounting facilitation from the length dimension to the width dimension. Instead of increasing the inner length L1 of the frame to create clearance, the side covers are deformed outward in the width direction to create space for the guide member and battery cell stack insertion. This dimensional shift allows the length to remain optimized for volume while providing sufficient clearance through width expansion, resolving the contradiction between volume efficiency and mounting ease.

AI summary
An apparatus for mounting a battery cell mounts a battery cell stack to a frame that includes a base cover and a pair of side covers respectively extending from both ends of the base cover. The apparatus includes a support member to support the battery cell stack, a roller member around which a film fixed to the support member is wound, and a film guide member configured to move the film into the frame. When the film guide member moves the film into the frame, the support member and the frame move toward each other, and the battery cell stack is movable along the film to be mounted to the frame.
