Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Battery packs face challenges in maintaining stability when battery modules are arranged in a double-layer configuration, particularly in high electrical demand applications like electric vehicles, where space is limited and supporting stability is crucial.
Innovation Solution
A battery pack design featuring a double-layer battery module bracket with an upper and lower fixing member, a fastener passing through these members in the Z direction, and a supporting mechanism to securely hold the battery modules, enhancing structural rigidity and impact resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If battery modules are arranged in a double-layer manner to increase electrical capacity, then the electrical requirements can be met, but the supporting stability of the battery modules deteriorates
Solution Approach 1:
The bracket is divided into multiple segments including upper and lower fixing members with multiple fixing components distributed at different positions. Each fixing component independently supports the battery modules, creating a segmented support system that enhances overall stability while accommodating double-layer arrangement
Solution Approach 2:
The patent introduces multi-dimensional fixing by positioning fixing components not only in the horizontal plane but also at different vertical levels and depths. The fixing components extend in multiple directions (X, Y, Z axes) to provide comprehensive support for the double-layer battery module arrangement, transforming a simple vertical stacking problem into a multi-dimensional structural solution
2Volume of moving object
If battery modules are arranged in a double-layer manner to utilize limited height space, then space utilization improves, but the structural rigidity deteriorates
Solution Approach 1:
The bracket structure is pre-configured with multiple fixing components positioned to provide support before the battery modules are installed. The upper and lower fixing members are arranged in advance to create a stable framework that maintains structural rigidity from the outset, preventing deformation under the weight of double-layer battery modules
Solution Approach 2:
The patent introduces intermediate supporting structures including upper and lower fixing members that act as mediators between the battery modules and the bracket body. These intermediate components distribute loads and provide additional support points, enhancing structural rigidity without compromising the compact double-layer arrangement
