Energy Storage Suspension Assembly for Compact Module Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in assembling large energy storage modules in a compact and simple manner while ensuring sufficient strength and modularity for heavy-duty vehicles, such as trucks and construction equipment, to support electric traction motors.
Innovation Solution
An energy storage suspension arrangement comprising a first and second member connected by a rod through a nut with internal threads, allowing for stacked layers of modules to be suspended and easily assembled, with optional additional members for further layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If energy storage modules are assembled in a compact stacked arrangement, then the space utilization and vehicle range are improved, but the assembly complexity and difficulty of providing sufficient suspension strength increase
Solution Approach 1:
The suspension arrangement is divided into discrete members (first member, second member) with specific apertures and connection points, allowing each component to be independently manufactured and assembled in a standardized sequence, thereby reducing overall assembly complexity while enabling compact stacking
Solution Approach 2:
The first and second members are designed with universal features (apertures, support surfaces, geometric axis alignment) that allow them to serve multiple functions: structural support, modular connection points for stacking, and standardized assembly interfaces, simplifying the overall assembly process across multiple layers
2Strength
If the energy storage suspension arrangement provides sufficient strength to support heavy modules, then the load-bearing capacity is improved, but the assembly simplicity and ease of installation deteriorate
Solution Approach 1:
The nut is pre-positioned in the second aperture before final assembly, and the rod is designed to pass through pre-aligned apertures and connect to pre-positioned support surfaces, allowing the heavy-duty connection to be made in a simple sequential assembly process without requiring complex alignment or adjustment during installation
3Adaptability or versatility
If the suspension arrangement uses a modular stacked design, then the adaptability and ease of configuration are improved, but the structural integrity and strength may deteriorate
Solution Approach 1:
The rod merges the first and second members into a unified load-bearing structure by passing through both members and connecting to their respective support surfaces, creating a continuous structural path that maintains high structural integrity while preserving the modular stacked configuration
