Solution Overview
Problem
Freight trains with fixed chassis sizes face inefficiencies in transporting goods of varying sizes, leading to wasted space or inability to load containers, which affects transportation efficiency and volume in railway transportation.
Innovation Solution
A modular freight train chassis system comprising a first chassis module, connecting modules, and adjustable second chassis modules, allowing for flexible adjustment of length to accommodate different container sizes through connecting members, tensioners, and adjusting plates, enhancing adaptability and space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed size chassis is used for freight train, then the manufacturing process is simple and production is efficient, but the adaptability to different sizes of containers is poor leading to wasted space or inability to load
Solution Approach 1:
The chassis is divided into multiple independent modules (first chassis module, second chassis modules) that can be connected or disconnected based on cargo requirements. Each module has standardized connection interfaces allowing flexible reconfiguration to match different container sizes, thereby improving adaptability without requiring complete redesign of the entire chassis structure.
Solution Approach 2:
The chassis transitions from a fixed static structure to a dynamic reconfigurable system. The connecting modules enable the chassis length and configuration to be changed according to cargo needs, allowing the same chassis to adapt to various container sizes through modular assembly and disassembly operations.
2Productivity
If a fixed size chassis is used for freight train, then the manufacturing cost is controlled, but the space utilization rate is low when transporting different sized goods
Solution Approach 1:
By segmenting the chassis into standardized modules, the system can be configured to match the actual cargo volume, eliminating unnecessary empty space in the chassis while maintaining manufacturing efficiency through standardized module production and assembly.
Solution Approach 2:
The chassis configuration parameters (length, module arrangement) can be changed to optimize space utilization for different cargo types. This allows the chassis to be adjusted to the minimum necessary size for each cargo load, reducing wasted space and improving transportation efficiency.
3Strength
If a welded overall structure is used for the chassis, then the structural strength is high, but the flexibility to adjust size for different cargo is lost
Solution Approach 1:
The chassis is segmented into modular units with standardized connection interfaces that provide sufficient strength to bear cargo loads. The connection between modules is designed to maintain structural integrity while allowing for easy assembly and disassembly, thus preserving both strength and flexibility.
Solution Approach 2:
Multiple chassis modules are merged through standardized connecting modules to form the complete chassis structure. The connection design combines the benefits of modular flexibility with the strength of integrated structure, ensuring that the assembled chassis maintains the structural strength of a welded overall structure while retaining the ability to reconfigure.
