Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional assembly line facilities for battery modules require redundant investment and increased space due to a linear logistics flow, making them unsuitable for manufacturing stacked battery modules without doubling the facility setup.
Innovation Solution
An assembly line system with a circulation structure of an 'E' shape, comprising first, second, and third facility lines, where the first-layer cell module assembly is reversed to enable a second-layer assembly, reducing redundant facilities and optimizing space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional assembly line facilities with linear logistics flow are used for stacked battery modules, then the manufacturing process can be implemented, but redundant facility investment and increased space are required
Solution Approach 1:
The patent inverts the conventional linear logistics flow by implementing a circulation structure where the assembly line returns to the origin after completing one layer assembly. This allows the same facility to be reused for assembling subsequent layers, eliminating the need for redundant facilities and reducing overall layout area while maintaining manufacturing capability
Solution Approach 2:
The circulation structure enables a single assembly line facility to perform multiple functions by assembling different layers sequentially. The facility that assembles the first layer then returns to assemble the second layer, making the same equipment serve multiple purposes throughout the production cycle, thereby reducing total facility investment
2Ease of manufacture
If conventional assembly line facilities with linear logistics flow are used for stacked battery modules, then the manufacturing process can be implemented, but the length and area of equipment layout increase
Solution Approach 1:
By inverting the linear flow into a circulation pattern, the equipment layout returns to the origin point after completing one layer assembly. This compact circulation path significantly reduces the overall length and area of the equipment layout compared to extending linear facilities for multiple layers, while preserving full manufacturing functionality
3Adaptability or versatility
If two facilities with the same concept are required for stacked battery module manufacturing, then complete assembly capability is achieved, but facility investment cost increases
Solution Approach 1:
The circulation structure transforms a single facility into a multi-functional system that can assemble multiple layers sequentially. The same equipment performs the complete assembly process for different layers by returning to the origin, eliminating the need for duplicate facilities while maintaining complete assembly capability, thus reducing facility investment
4Area of stationary object
If a circulation structure is implemented for assembly line facilities, then space efficiency is improved and redundant investment is reduced, but the logistics flow becomes more complex
Solution Approach 1:
The circulation structure inverts the simple linear flow into a reusable loop that returns to origin. While this creates a more complex path, the complexity is managed through systematic design of the circulation route, allowing space efficiency and investment reduction to outweigh the increased logistics complexity
