Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current battery cell manufacturing processes are inefficient, leading to reduced manufacturing throughput and increased time due to the discontinuous assembly of battery electrode layer stacks and housings.
Innovation Solution
The implementation of a system utilizing two conveyor mechanisms, a screw-type conveyor mechanism for moving the electrode layer stack and cap, and a second conveyor mechanism that rotates the housing around a screw to align and secure it with the electrode layer stack and cap in a continuous fashion, allowing for uninterrupted assembly of battery cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional discontinuous assembly processes are used, then device complexity is reduced, but manufacturing throughput decreases and manufacturing time increases
Solution Approach 1:
The patent combines multiple assembly operations (electrode layer stack insertion, cap coupling, and housing assembly) into a single continuous process using integrated conveyor mechanisms. The first conveyor mechanism moves the electrode layer stack and cap together, while the second conveyor mechanism simultaneously provides housing, creating a merged assembly line that eliminates discontinuous transfer operations and increases manufacturing throughput.
Solution Approach 2:
The patent implements continuous assembly by ensuring that the conveyor mechanisms operate without interruption. The first conveyor mechanism continuously moves electrode layer stacks and caps, while the second conveyor mechanism continuously provides housing at a substantially similar rate. This continuous operation eliminates idle time and maintains constant productive action throughout the assembly process.
2Loss of time
If traditional batch assembly methods are used, then equipment simplicity is maintained, but manufacturing time increases
Solution Approach 1:
The patent divides the assembly system into two specialized conveyor mechanisms with distinct functions. The first conveyor mechanism is dedicated to moving electrode layer stacks and caps, while the second conveyor mechanism is dedicated to providing housing. This segmentation allows each mechanism to be optimized for its specific task, reducing overall manufacturing time while managing complexity through functional specialization.
Solution Approach 2:
The patent prepares components for assembly in advance by having the first conveyor mechanism pre-position electrode layer stacks and caps on the assembly line before the housing is provided by the second conveyor mechanism. This preliminary preparation of components eliminates waiting time during the assembly process and reduces total manufacturing time.
3Productivity
If continuous assembly is implemented, then manufacturing throughput increases, but alignment precision requirements increase
Solution Approach 1:
The patent synchronizes the two conveyor mechanisms to operate at substantially similar rates, creating an equipotential assembly rhythm. The first conveyor mechanism moves electrode layer stacks and caps at a rate matched by the second conveyor mechanism providing housing, ensuring that components are always available at the assembly point without causing misalignment or waiting, thus maintaining precision while enabling continuous high-speed operation.

Function Achieved in This Case
This approach significantly increases manufacturing throughput by ensuring continuous assembly with minimal downtime, allowing for rapid production of battery cells with precise alignment and secure housing of the electrode layers.
Implementation Method 1
The first conveyor mechanism can be or include a screw conveyor mechanism that translates the electrode layer stack and the cap via rotation of a screw
Implementation Method 2
The second conveyor mechanism can be or include a screw structured to translate a housing along a helical path around the screw. The screw of the second conveyor mechanism can receive a housing and can rotate the housing about the screw as the screw rotates

AI summary
A system to assemble a battery cell can include a first conveyor mechanism and a second conveyor mechanism. The first conveyor mechanism can move an electrode layer stack and a cap in a first direction. The electrode layer stack can abut the cap and extend from the cap in a second direction. The second conveyor mechanism can include a screw. The second conveyor mechanism can receive a housing, rotate the housing about the screw, and provide the housing over the electrode layer stack.
