Modular Carrier Board Locking Elements for Battery Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cell contacting systems for lithium ion battery modules are inflexible and cannot efficiently accommodate various battery types with different numbers of cells and wiring configurations, limiting their application in producing diverse battery types with minimal manufacturing overhead.
Innovation Solution
A carrier board element with uniformly spaced cell holders and locking elements that allow multiple cell connectors to be captively locked, enabling flexible configuration and adaptation to different battery types by using a tongue-and-groove connection or plastic welding, and featuring snap-in hooks or hot-pressed pins for secure locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional carrier plates with fixed geometry are used, then the system is simple to manufacture, but it cannot accommodate different battery types with varying wiring configurations
Solution Approach 1:
The carrier board is divided into multiple modular carrier board elements, each with standardized locking elements. This segmentation allows flexible assembly to accommodate different battery configurations while maintaining manufacturing simplicity through standardized components.
Solution Approach 2:
The locking elements are designed with universal geometry that can accommodate multiple cell connectors with the same connector geometry. This universal design enables a single locking element type to serve various battery types and wiring configurations, increasing adaptability without proportionally increasing device complexity.
2Adaptability or versatility
If multiple different cell connector geometries are used to accommodate different battery types, then adaptability improves, but manufacturing overhead and device complexity increase
Solution Approach 1:
The locking elements are designed with universal geometry that can accommodate multiple cell connectors with the same connector geometry. This universal design enables a single locking element type to serve various battery types and wiring configurations, increasing adaptability without proportionally increasing device complexity.
Solution Approach 2:
The system achieves adaptability through parameter changes in the arrangement and number of locking elements rather than changing the geometry of the locking elements themselves. This allows the same locking element design to be used across different battery types by simply adjusting configuration parameters.
3Ease of manufacture
If carrier plates are designed for specific wiring types, then manufacturing is simplified, but the system cannot cover multiple battery types with different wiring
Solution Approach 1:
The carrier board is divided into multiple modular carrier board elements, each with standardized locking elements. This segmentation allows flexible assembly to accommodate different battery configurations while maintaining manufacturing simplicity through standardized components.
Solution Approach 2:
The system transitions from static, wiring-specific carrier plates to a dynamic, reconfigurable carrier board system. The modular elements with standardized locking elements can be dynamically assembled to match different wiring configurations, achieving both manufacturing simplicity and wiring flexibility.
