Flame-Retardant Sheet Alignment on Inclined Battery Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The attachment of flame-retardant sheets to battery modules, especially those with inclined surfaces, faces challenges in alignment accuracy, which affects the effectiveness of heat transfer delay and safety in battery packs.
Innovation Solution
A device and method utilizing a first pressurizing device to align and restrict movement in one direction, and a second pressurizing device to align and slide the flame-retardant sheet in a perpendicular direction, ensuring accurate positioning and attachment to battery modules, even on uneven surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flame-retardant sheet with an inclined surface is attached to a battery module, then the heat transfer between battery modules is reduced, but the alignment accuracy of the flame-retardant sheet deteriorates
Solution Approach 1:
The pressurizing device is divided into two independent pressurizing units that can apply pressure in different directions separately. This segmentation allows independent control of pressure application in the first direction (perpendicular to sheet) and second direction (parallel to sheet for alignment), resolving the contradiction between achieving proper attachment and maintaining alignment accuracy on inclined surfaces
Solution Approach 2:
The pressurizing devices are designed to be movable and adjustable, allowing dynamic positioning and pressure application. The first pressurizing device can move to restrict movement in the first direction, while the second pressurizing device can move to enable controlled movement in the second direction, adapting to the inclined surface geometry while maintaining alignment accuracy

AI summary
A flame-retardant sheet attaching device is disclosed. The flame-retardant sheet attaching device may include a first pressurizing device configured to move in a first direction and apply pressure to a flame-retardant sheet, and a second pressurizing device configured to move in the first direction, the second pressurizing device having at least a portion inserted into a groove of the flame-retardant sheet. The flame-retardant sheet may be configured to move, based on the movement of the second pressurizing device, in a second direction, perpendicular to the first direction. The first pressurizing device may be configured to restrict the movement of the flame-retardant sheet in the first direction, when the flame-retardant sheet moves in the second direction.
