Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly difficulty between the current collector component and the electrode column in battery cells is high, leading to low production efficiency and poor production quality.
Innovation Solution
A mounting rack is provided between the first wall and the main body part of the electrode assembly, connecting the current collector component to stabilize and support it, reducing shaking and facilitating assembly and connection with the electrode column.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the current collector component is directly assembled without a mounting rack, then the assembly process is simpler, but the assembly difficulty between current collector component and electrode column increases, leading to poor production quality
Solution Approach 1:
The mounting rack serves as an intermediary component between the current collector component and the electrode column. It provides a standardized interface that facilitates precise alignment and connection, thereby improving connection quality without significantly complicating the assembly process. The mounting rack acts as a mediator that resolves the positioning and alignment challenges between the current collector component and electrode column.
2Manufacturing precision
If a mounting rack is added to stabilize the current collector component, then the production quality and stability improve, but the device complexity increases
Solution Approach 1:
The mounting rack is designed to perform multiple functions: it stabilizes the current collector component, facilitates assembly with the electrode column, provides structural support, and ensures proper positioning. By consolidating these multiple functions into a single component, the design avoids the need for multiple separate parts, thereby limiting the increase in device complexity while achieving improved production quality and stability.
3Stability of the object's composition
If the current collector component is stabilized with a mounting rack, then shaking and displacement are reduced, but the assembly time and production complexity increase
Solution Approach 1:
The mounting rack is pre-installed in the battery cell structure before the current collector component is assembled. This preliminary action prepares the assembly environment in advance, allowing the current collector component to be quickly positioned and secured without requiring complex alignment procedures during the assembly process. The pre-positioned mounting rack reduces assembly time and maintains production efficiency while ensuring component stability.

AI summary
A battery cell, a battery, and an electrical apparatus. The battery cell includes a shell, an electrode assembly, an electrode column, a current collector component, and a mounting rack. The shell has a first wall. The electrode assembly is accommodated inside the shell, and includes a main body part and a tab. Along the thickness direction of the first wall, the tab is set at one end of the main body part facing the first wall. The electrode column is installed on the first wall. The current collector component connects the electrode column and the tab. Along the thickness direction of the first wall, the mounting rack is set between the first wall and the main body part, and the current collector component is connected to the mounting rack.
