Battery Module Bracket With Elastic Cell Positioning During Adhesive Curing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of battery modules is inefficient due to the need for a positioning tool to remain until structural adhesive cures, limiting tool utilization and increasing mass production difficulties, and there is a risk of cell shifting during adhesive curing and aging, leading to potential welding failures.
Innovation Solution
A bracket with a base and positioning devices featuring elastic structures that surround placement grooves, allowing cells to be directly loaded and aligned without a positioning tool, maintaining stability during adhesive curing and use, and providing balanced support to prevent shifting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a positioning tool is used to hold cells during adhesive curing, then cell position stability is improved, but assembly efficiency deteriorates because the tool cannot be removed until curing completes
Solution Approach 1:
The bracket itself provides positioning functionality through elastic structures that directly contact and stabilize cells during adhesive curing, eliminating the need for external positioning tools. The bracket serves dual functions: structural support and positioning, enabling self-service positioning without additional equipment
Solution Approach 2:
The positioning function is extracted from a separate positioning tool and integrated directly into the bracket structure through elastic positioning structures, allowing the bracket to perform both support and positioning functions simultaneously without requiring external tooling
2Manufacturing precision
If a positioning tool is used to prevent cell shifting during adhesive curing, then positioning accuracy is improved, but device complexity increases due to additional tooling requirements
Solution Approach 1:
The positioning function is merged with the bracket structure itself through integrated elastic positioning structures. The bracket combines structural support and positioning functions in a single component, eliminating the need for separate positioning tools and reducing overall system complexity
Solution Approach 2:
The bracket is designed with multi-functionality, serving both as the structural mounting component and as the positioning device through its elastic structures. This universal design eliminates the need for specialized positioning tooling, simplifying the overall assembly process
3Strength
If structural adhesive is used to fix cells to the bracket, then bonding strength is improved, but assembly time increases due to required curing duration
Solution Approach 1:
Elastic positioning structures are installed on the bracket in advance, providing immediate mechanical support and positioning for cells during assembly. This preliminary mechanical stabilization occurs before adhesive curing, allowing cells to be securely positioned without waiting for adhesive to set
Solution Approach 2:
Elastic positioning structures act as intermediary mechanical elements between the bracket and cells during the adhesive curing process. These intermediaries provide continuous physical support and positioning, compensating for the time-dependent nature of adhesive curing by offering immediate mechanical stability
