Battery Module Support Brackets for Vibration-Stable Energy Storage
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 the 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 the 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 battery cells, then stability and reliability improve, but device complexity and volume available for battery cells decrease
Solution Approach 1:
The patent introduces support brackets as intermediary elements between the housing and battery cells. These brackets serve as mediators that absorb and reduce vibrations and undesired movements, thereby protecting the battery cells without requiring extensive reinforcement of the housing structure itself. This intermediary approach resolves the contradiction by providing stability through added components rather than through complex structural reinforcement.
2Reliability
If additional reinforcement is added to minimize vibrations and movements of battery cells, then reliability improves, but the volume available for battery cells decreases
Solution Approach 1:
The support brackets act as compact intermediary elements that provide vibration reduction and stability without occupying significant volume. By placing these brackets strategically within the housing structure, the patent achieves reliable battery cell support while maximizing the remaining volume available for accommodating battery cells, thus resolving the volume-tradoff.
3Reliability
If the energy storage module is tightly constrained to reduce movements, then reliability improves, but manufacturing precision requirements increase
Solution Approach 1:
The patent employs tolerance adjustment members that can be configured in at least two different configurations, allowing the system to accommodate variations in manufacturing tolerances. By adjusting the extension of these members, the energy storage module can be securely positioned without requiring extremely tight manufacturing precision, thus resolving the contradiction between reliability and manufacturing precision requirements.
