Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Energy storage assemblies in electric vehicles face challenges in minimizing vibrations and undesired movements of battery cells, which can require additional reinforcement, thereby reducing the available volume for battery cells.
Innovation Solution
The energy storage assembly incorporates a housing with support brackets and tolerance adjustment members that have multiple configurations to securely position the battery cells, reducing vibrations and movements, allowing for a larger volume for battery cells without the need for additional reinforcement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional reinforcement is added to minimize vibrations and movements of the energy storage module, then the stability and reliability improve, but the volume available for battery cells decreases
Solution Approach 1:
The support structure is divided into multiple discrete brackets distributed around the energy storage module, with individual tolerance adjustment members at each bracket location. This segmentation allows localized vibration control without requiring a comprehensive reinforcement of the entire housing structure, thereby maintaining battery cell volume.
Solution Approach 2:
Tolerance adjustment members are introduced as intermediary elements between the support brackets and the energy storage module. These members actively compensate for dimensional variations and reduce vibrations, providing the necessary stability without adding rigid reinforcement structures that would consume battery cell volume.
2Reliability
If tolerance adjustment members with multiple configurations are used to reduce vibrations and movements, then the reliability improves, but the device complexity increases
Solution Approach 1:
The tolerance adjustment members utilize parameter changes in their extension dimensions to adapt to different assembly conditions. By providing multiple configuration options with different extension lengths, the system can optimize the support characteristics without requiring complex active control mechanisms, thus maintaining reliability while limiting complexity.
Solution Approach 2:
The tolerance adjustment members are designed with the capability to change their extension parameter dynamically during assembly or operation. This dynamic adaptability allows the support structure to optimize its characteristics for vibration reduction without requiring a permanently complex multi-component system.
