Suspendable Battery Module Layout for Heavy-Vehicle Frame Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of securely connecting and efficiently assembling large and heavy energy storage modules to the frame of heavy-duty vehicles, particularly in electric traction systems, while allowing for easy disconnection during maintenance, is addressed.
Innovation Solution
The energy storage arrangement features individually suspendable energy storage modules connected by frame connecting members and protection plates, allowing each module to be securely attached to the vehicle frame without load-bearing structures between them, facilitating easy disassembly and reducing twist motions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If energy storage modules are connected using load-bearing structures between modules, then structural strength is improved, but device complexity and assembly difficulty increase
Solution Approach 1:
The energy storage system is divided into independent modules that are suspended individually from the frame. Each module has its own frame connecting member, eliminating the need for complex load-bearing structures between modules. The modules are arranged side by side with geometric gaps, and protection plates extend across these gaps to provide structural integrity without direct load-bearing connections between modules.
2Stability of the object's composition
If energy storage modules are rigidly connected to form a uniform structure, then structural rigidity is improved, but ease of maintenance deteriorates
Solution Approach 1:
The system uses individually suspendable modules that can be independently removed from the frame. The protection plates extend across geometric gaps between modules but do not create rigid load-bearing connections, allowing modules to be detached separately for maintenance while maintaining overall structural stability during operation.
3Volume of moving object
If modules are directly connected without geometric gaps, then structural compactness is improved, but stress transmission and twist motion increase
Solution Approach 1:
Geometric gaps are introduced between adjacent energy storage modules, and protection plates extend across these gaps. The gaps act as intermediaries that decouple the modules, preventing twist motions and stress from being transmitted between them while the protection plates provide necessary structural support and protection.
