Detachable Battery Module Assembly for Adjustable Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery systems lack flexibility in adjusting capacity and weight based on specific use cases, such as varying power demands in devices like electric vehicles, without compromising power supply during module detachment.
Innovation Solution
A battery module assembly with detachable groups of battery modules, where a first group remains mounted while a second group can be detached, maintaining power supply, and controlled by a management unit to optimize electrical connections and capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all battery modules are mounted on the frame, then power supply capacity is maximized, but weight and capacity cannot be adjusted for different use cases
Solution Approach 1:
The battery modules are divided into a first group (permanently mounted) and a second group (detachably mounted). This segmentation allows the second group to be removed for weight reduction while the first group remains to ensure continuous power supply, resolving the contradiction between adaptability and reliability.
2Adaptability or versatility
If battery modules are made detachable for weight adjustment, then adaptability improves, but system complexity increases
Solution Approach 1:
The battery system is segmented into permanently mounted modules (first group) and detachably mounted modules (second group). This segmentation simplifies the overall system by maintaining a clear distinction between essential and optional components, reducing the complexity of mounting and electrical connection systems while preserving flexibility.
3Adaptability or versatility
If battery modules are arranged in a fixed configuration, then manufacturing simplicity is maintained, but adaptability to different power demands is limited
Solution Approach 1:
The battery modules are segmented into two groups with different mounting characteristics. The first group uses fixed mounting for manufacturing simplicity, while the second group uses detachable mounting for adaptability. This segmentation allows the system to achieve both manufacturing ease and adaptability to varying power demands.
Solution Approach 2:
The battery module assembly is designed with universal mounting interfaces that accommodate both permanently mounted and detachably mounted modules. This multi-functionality allows the same mounting structure to serve dual purposes: providing stable fixed mounting for the first group and enabling easy detachment for the second group, thereby maintaining ease of manufacture while achieving adaptability.
