Battery Module Assembly Jig with Segmented Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During the assembly of battery modules, the circuit board's orientation and distance from the battery cell are not consistently maintained, leading to improper attachment of connection members due to unintentional movement caused by external forces like soldering tools.
Innovation Solution
A jig with a housing featuring separate accommodation portions for the battery cell and circuit board, along with protective covers and support units, maintains the circuit board's orientation and distance from the battery cell, preventing unintentional movement and ensuring accurate attachment of connection members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the circuit board is disposed spaced apart from the battery cell during soldering, then the connection member can be attached to the circuit board, but the soldering tool may push the circuit board causing unintentional movement and non-uniform orientation
Solution Approach 1:
The patent introduces a support structure as an intermediary between the circuit board and the battery cell. This support structure includes a support portion that contacts the circuit board and a column portion that extends downward, providing stable positioning. The intermediary support structure prevents direct contact forces from the soldering tool from causing unintentional movement of the circuit board, thereby maintaining manufacturing precision while allowing the attachment operation to proceed.
2Stability of the object's composition
If the circuit board is held close to the battery cell, then stability is improved, but the connection member cannot be properly attached due to insufficient space for soldering operations
Solution Approach 1:
The patent segments the support structure into distinct functional portions: a support portion that contacts the circuit board to maintain its position, a column portion that extends downward to provide structural support, and a predetermined space between the circuit board and battery cell. This segmentation allows the circuit board to be held stably at a specific distance from the battery cell, providing sufficient space for soldering operations while maintaining positional stability.
3Productivity
If external force is applied to the circuit board during soldering, then the connection member can be attached, but the distance between circuit board and battery cell becomes non-uniform
Solution Approach 1:
The patent implements preliminary action by providing a support structure before the soldering operation begins. The support structure is positioned to contact the circuit board and maintain it at a predetermined distance from the battery cell. This preliminary positioning ensures that even when external forces are applied during the attachment process, the circuit board remains at the correct distance, maintaining manufacturing precision throughout the operation.
