Modular Assembly Pallet with Adjustable Positioning for Battery Cell Stacks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing assembly pallets are not adaptable to various vehicle battery pack shapes and sizes, leading to inefficiencies in production, storage, and assembly, as they are not specifically designed for cell stacks and can interfere with the supporting blocks.
Innovation Solution
A modular assembly pallet with a positioning engagement member and restraining mechanism that allows for the assembly of cell stacks with different geometries by adjusting folding pins and restraining rods, enabling flexible positioning and secure assembly of multiple types of cell stacks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed supporting block is used on the pallet, then the pallet structure is simple, but the pallet cannot be adapted to different battery pack types and may interfere with the battery pack
Solution Approach 1:
The supporting block is designed to be movable rather than fixed, allowing it to be adjusted or removed according to different battery pack types. This dynamic configuration enables the same pallet to accommodate various battery pack geometries without structural interference, resolving the contradiction between adaptability and structural simplicity.
2Adaptability or versatility
If different assembly pallets are used for different vehicle battery packs, then each battery pack type can be properly assembled, but production efficiency decreases due to frequent pallet changes
Solution Approach 1:
The pallet is designed with universal adaptability through movable supporting blocks and adjustable positioning engagement members that can accommodate multiple battery pack types. This multi-functional design allows a single pallet to serve various assembly purposes, eliminating the need for frequent pallet changes and thereby improving production efficiency while maintaining compatibility with different battery pack shapes.
3Adaptability or versatility
If a movable positioning engagement member is added to enable selective assembly of different cell stacks, then adaptability improves, but the device complexity increases
Solution Approach 1:
The positioning engagement member is designed as a segmented, modular component that can be independently adjusted. This segmentation allows for simplified construction and easier adjustment mechanisms compared to a monolithic positioning system, thereby reducing the overall device complexity while maintaining the capability for selective assembly of different cell stack geometries.

AI summary
An assembly pallet is assembled a cell stack to. The cell stack that includes a cell group in which a plurality of electric cells are stacked, end plates arranged in a position between which the cell group is interposed, and a restraining member for applying a restraint that restrains the cell group to the end plates. The assembly pallet includes a positioning engagement member that is engaged with the restraining member to effect positioning of the cell stack.
