Sliding Plate Battery Cell Tray for Curved Cells
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery cell trays fail to accommodate and securely fix curved battery cells, leading to potential damage and fire risks during charging and discharging.
Innovation Solution
A battery cell tray design featuring a lower and upper plate that slide relative to each other, with protrusions and grooves allowing for secure accommodation and fixation of curved cells, and an additional plate for stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wide tray is used to accommodate curved battery cells, then the battery cells can be accommodated, but the battery cells can move and damage the exterior and create fire risk
Solution Approach 1:
The tray employs a movable upper plate that can slide between an opened state (for battery cell insertion) and a closed state (for secure fixation). This dynamic structure allows the tray to adapt to curved battery cells while preventing movement during charging and discharging, thereby resolving the contradiction between accommodation capability and safety
Solution Approach 2:
The tray is divided into a lower plate and an upper plate that can move independently. The lower plate provides the accommodation space while the upper plate provides the closing function. This segmentation allows each part to perform its specific function optimally - the lower plate accommodates the curved battery cells and the upper plate secures them by closing the opening
2Reliability
If the upper plate closes the opening to fix the battery cell, then the battery cell is secured, but the battery cell cannot be inserted or removed
Solution Approach 1:
The upper plate is designed to be movable rather than fixed, allowing it to slide between opened and closed positions. This dynamic design enables the tray to provide secure fixation when closed while allowing easy insertion and removal when opened, resolving the contradiction between fixation stability and ease of operation
Solution Approach 2:
The tray structure is pre-configured with guides and supports that automatically position the battery cell correctly as it is inserted. This preliminary positioning action ensures that when the upper plate closes, the battery cell is already in the correct position for secure fixation, making the insertion process straightforward and the fixation reliable

AI summary
The present disclosure relates to a battery cell tray and a battery cell tray assembly, and the battery cell tray includes a lower plate where an accommodation portion accommodating one end of the battery cell is formed and an upper plate formed to be penetrated by the battery cell, wherein the lower plate and the upper plate may be coupled to each other in a sliding movable way between a first state where an opening of the accommodation portion is opened and a second state where an opening of the accommodation portion is at least partially closed. The battery cell tray and the battery cell tray assembly according to the present disclosure may accommodate, fix and move curved battery cells, and reduce the risk of damage to curved battery cells and fire during charging and discharging.
