Solution Overview
Problem
Existing commercial vehicle chassis designs are inflexible and require significant effort to modify, limiting the arrangement of large functional components due to fixed structural configurations, often necessitating the division of large components into smaller ones and requiring cumbersome adapter solutions.
Innovation Solution
A modular and reconfigurable vehicle chassis system with interchangeable modules, featuring a rear support structure with multiple connection nodes and a frame overhang, allowing for adjustable positioning and connection of longitudinal members via brackets and clamping elements, enabling flexible arrangement of axles and components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a fixed one-piece continuous longitudinal beam chassis design is used, then structural integrity and stability are ensured, but flexibility and adaptability for different applications are reduced
Solution Approach 1:
The chassis is divided into modular segments including longitudinal beams with integrated connection nodes, allowing the structure to be assembled in different configurations. The connection nodes enable detachable connections between modules, providing adaptability while maintaining structural integrity through standardized joining mechanisms.
Solution Approach 2:
The chassis design transitions from a static fixed structure to a dynamic reconfigurable system. The detachable connection nodes allow the chassis to be reconfigured between different application requirements, enabling the same basic structure to adapt to various load cases and functional demands throughout the vehicle's service life.
2Manufacturing precision
If the chassis design is fixed and manufactured, then manufacturing precision and structural consistency are achieved, but subsequent modifications require considerable effort and may compromise structural integrity
Solution Approach 1:
The chassis is segmented into standardized modules with integrated connection nodes that facilitate detachable connections. This segmentation allows modifications to be made by simply disconnecting and reconnecting modules rather than performing complex welding or structural alterations, thereby maintaining manufacturing precision while enabling easy modifications.
Solution Approach 2:
The connection nodes are designed with universal functionality to accommodate different configuration requirements. The same connection node design can be used across multiple chassis modules and applications, providing a standardized interface that simplifies both initial manufacturing and subsequent modifications without compromising structural consistency.
3Device complexity
If large functional components are mounted on a fixed chassis, then component integration is simplified, but space constraints limit the arrangement of components
Solution Approach 1:
The chassis modules with standardized connection nodes provide a flexible platform for mounting functional components. Large components can be positioned at different locations along the modular chassis structure, and the detachable connections allow for easy repositioning or removal of components to optimize space utilization according to specific application requirements.
Solution Approach 2:
The modular chassis design enables dynamic reconfiguration of component arrangements. As application requirements change or components need to be upgraded, the standardized connection nodes allow for straightforward repositioning of functional components without requiring complex structural modifications, thereby maintaining both integration simplicity and arrangement flexibility.
