Battery Pack Housing Rib Structure for Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery packs face challenges in durability and reliability due to uneven distribution of load and lack of rigidity in supporting structures.
Innovation Solution
A battery pack design featuring a housing with protrusions and ribs extending in different directions, connected by fastening bosses and ribs, which distribute the load and enhance rigidity by connecting multiple battery modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple housing structure is used, then manufacturing cost and complexity are reduced, but load distribution and structural rigidity deteriorate
Solution Approach 1:
The housing is segmented into multiple functional components: housing protrusions that extend into the battery module, multiple housing ribs extending in different directions from each protrusion, and multiple housing bosses for fastening. This segmentation allows each component to perform its specific function optimally while collectively providing superior load distribution and structural rigidity compared to a simple monolithic housing structure.
Solution Approach 2:
The housing ribs extend in multiple directions (different dimensions) from each housing protrusion, creating a three-dimensional rib network structure. This multi-directional arrangement distributes loads along multiple pathways and enhances structural rigidity by engaging the housing in multiple spatial dimensions, rather than relying on a single-plane reinforcement approach.
2Strength
If housing ribs are added to enhance rigidity, then structural integrity is improved, but device complexity increases
Solution Approach 1:
The housing ribs are merged with the housing protrusions, forming an integrated structure where the ribs extend directly from the protrusions. This merging eliminates the need for separate reinforcement components, reducing overall device complexity while still providing enhanced structural rigidity through the rib network.
Solution Approach 2:
The housing protrusions serve multiple functions: they provide attachment points for the battery module, serve as structural reinforcement elements, and act as connection points for multiple housing ribs that distribute loads in different directions. This multi-functionality reduces the need for additional specialized components, maintaining simplicity while enhancing strength.
