Detachable Battery Cabinet Sidewall for Module Assembly Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high production costs and low assembly efficiency of batteries due to the integrally welded cabinet structure, which requires sequential hoisting of battery modules, leading to difficulties in automation and maintenance.
Innovation Solution
A battery design with a detachable side surface of the cabinet allows battery modules to be placed sideways, improving assembly and maintenance efficiency by enabling non-sequential placement and easy removal of faulty modules without affecting others.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the cabinet uses an integrally welded structure, then the structural strength is improved, but the assembly efficiency deteriorates due to sequential hoisting requirements
Solution Approach 1:
The cabinet is divided into a fixed part and a detachable side surface that can be separated. This segmentation allows the side surface to be removed for efficient module assembly while the fixed part maintains structural strength, resolving the contradiction between integrated structure and assembly efficiency.
2Stability of the object's composition
If battery modules are placed by sequential hoisting, then the structural integrity is maintained, but the production costs increase and automation becomes difficult
Solution Approach 1:
The cabinet transitions from a static integrated structure to a dynamic structure with detachable components. The side surface can be detached during assembly to enable flexible module placement and then reattached to maintain structural integrity, facilitating automation and reducing costs.
3Manufacturing precision
If the cabinet structure is fixed and integrated, then the manufacturing precision is improved, but the ease of repair deteriorates due to difficulty in module removal
Solution Approach 1:
The cabinet is segmented into fixed and detachable portions, allowing precise manufacturing of the fixed structure while enabling easy removal and replacement of battery modules through the detachable side surface for maintenance and repair.
4Stability of the object's composition
If sequential hoisting is used for module assembly, then the structural stability is maintained, but the loss of time increases due to inefficient assembly process
Solution Approach 1:
The cabinet structure dynamically changes during assembly by detaching the side surface to enable parallel placement of multiple battery modules simultaneously, significantly reducing assembly time while maintaining structural stability through proper reattachment.
