Vehicle Closure Module Frame Structure for Energy Dispersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle frame structures concentrate impact loads during collisions, leading to potential damage and injury, as they lack the flexibility to adapt door types and effectively disperse collision energy.
Innovation Solution
A closure module frame structure featuring a platform with spaced cabin frames, middle connection parts, load path units, and a cabin unit that can be fastened to the frames, allowing for various door configurations and energy dispersion through a multi-load path structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional vehicle frame structure is used, then the structure is simple and easy to manufacture, but the impact load is concentrated on a specific part causing damage and injury
Solution Approach 1:
The frame structure is divided into multiple load path units (first, second, third, and fourth load path units) that are spatially separated and connected through cabin frames. This segmentation allows collision energy to be distributed across multiple distinct paths rather than concentrated at a single location, resolving the contradiction by creating a complex yet functional multi-path load distribution system.
Solution Approach 2:
The load path units are arranged in both longitudinal and lateral dimensions of the vehicle, creating a three-dimensional load distribution network. This multi-dimensional arrangement enables collision energy to be dispersed across different spatial planes, transforming a simple linear load path into a complex volumetric structure that effectively dissipates impact forces.
2Adaptability or versatility
If a fixed door type is used, then the structure is simple, but the vehicle cannot adapt to different purposes and space requirements
Solution Approach 1:
The closure module is designed as a detachable and replaceable component that can be dynamically changed based on vehicle requirements. Different door types (swing, sliding, hatchback, clamshell) can be installed by replacing the closure module, allowing the vehicle to adapt to various purposes such as passenger transport, cargo carrying, or space-constrained environments without permanent structural modifications.
Solution Approach 2:
The frame structure with standardized cabin frames and load path units serves as a universal platform that can accommodate multiple types of closure modules and cabin units. This multi-functional design enables the same basic structure to support different door configurations and vehicle purposes, resolving the contradiction between adaptability and complexity.
3Adaptability or versatility
If the cabin unit is permanently fixed, then the structure is stable, but the cabin cannot be detached or reconfigured for different uses
Solution Approach 1:
The cabin unit is pre-equipped with connection parts that align with corresponding structures on the load path units. This preliminary configuration ensures that when the cabin unit is attached, it automatically forms reliable load paths for collision energy dispersion. The pre-designed connection interfaces maintain structural integrity while allowing for detachable reconfiguration, resolving the contradiction between reliability and adaptability.
