Closed-Loop Battery Stack Assembly to Cut Floor Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional battery assembly processes require multiple stations and increased floor space, leading to complexity and prolonged production times due to the sequential addition of battery components in electric vehicle and energy grid storage batteries.
Innovation Solution
An automated battery assembly system utilizing a closed-loop transport track with multiple stations and a control system to move pallets in a predetermined sequence, allowing for the synchronized or asynchronous addition of battery components, such as cathode, anode, and separator plates, to efficiently assemble battery stacks.

Engineering Contradiction Analysis
1Productivity
If multiple battery components are added at a single station, then production time is reduced, but device complexity increases
Solution Approach 1:
The system divides the battery assembly process into multiple discrete stations (first assembly station, second assembly station, third assembly station, etc.), each responsible for adding specific battery components. This segmentation allows parallel processing of different components while maintaining manageable complexity at each individual station.
Solution Approach 2:
Each assembly station is designed as a multi-functional unit capable of adding different types of battery components (electrode plates, separators, terminals, casings). The stations can perform multiple operations including receiving components, assembling them onto the battery stack, and quality control, thereby reducing the need for specialized single-purpose stations.
2Ease of manufacture
If traditional assembly line with multiple stations is used, then battery components can be assembled, but floor space requirement increases
Solution Approach 1:
The system transitions from a linear horizontal arrangement of assembly stations to a vertical three-dimensional configuration where multiple stations are stacked at different heights. The transfer mechanism moves battery stacks vertically between floors, dramatically reducing the horizontal floor space required while maintaining the sequential assembly process.
Solution Approach 2:
The assembly system is nested within a multi-story building structure, with assembly stations located on different floors. The transfer mechanism is integrated within the building structure itself, nesting the transport function within the spatial framework of the assembly system.
