Battery Cell Spacer Structure for Stable Processing Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Battery cells tend to displace and fall over during processing due to instability, affecting processing quality and efficiency.
Innovation Solution
A spacer with a plate body and a restraint member is used to limit the position of the battery cell, preventing movement and ensuring stability by fitting between the plate body and the restraint member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If batteries are stacked and clamped by external force to keep them stable, then stability of battery cells is improved, but device complexity increases due to need for clamping mechanisms
Solution Approach 1:
The restraint function is extracted from external clamping mechanisms and integrated directly into the spacer structure through protrusions that extend from the plate body. This eliminates the need for separate clamping devices while maintaining stability.
Solution Approach 2:
The spacer structure provides its own restraint function through the protrusions that automatically limit battery cell positions without requiring external active control or additional clamping mechanisms. The structure serves both as a support and a restraint system.
2Stability of the object's composition
If restraint members are added to limit battery cell position, then stability is improved, but manufacturing complexity increases
Solution Approach 1:
The restraint member is merged with the plate body to form an integrated spacer structure. The protrusion is directly formed as part of the plate body, eliminating the need for separate restraint components and simplifying manufacturing processes.
3Ease of manufacture
If spacer structure is simplified, then ease of manufacture is improved, but reliability of battery cell positioning may worsen
Solution Approach 1:
The plate body has different local structures: a flat main body for support and protrusions for positioning. This local differentiation provides both manufacturing simplicity and reliable positioning without requiring complex overall structure.

AI summary
A spacer includes a plate body and a restraint member. The plate body has a first surface. The restraint member is connected to the plate body and extends along a direction leaving the first surface. The restraint member is configured to limit a position on an outer side of a battery cell, to block the battery cell from moving along the direction leaving the first surface.
