Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current intercirculation boxes for railway vehicles are heavy, bulky, and require multiple versions for different car widths, complicating assembly and maintenance due to limited access for wiring and connectors.
Innovation Solution
A modular intercirculation box with a support and guide structure comprising lateral guide modules that can be assembled in multiple configurations to adapt to different car end widths, allowing for flexible installation and improved accessibility during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single fixed-width box is manufactured for each car width, then the box provides precise fit and structural integrity, but it increases device complexity and requires multiple box versions
Solution Approach 1:
The box structure is divided into modular components including lateral guide modules, connection modules, and grounding modules that can be assembled in different configurations. This segmentation allows a single box design to adapt to multiple car widths without requiring separate box versions for each width.
Solution Approach 2:
The box employs adjustable and reconfigurable elements such as lateral guide modules with multiple assembly positions and connection modules with complementary orifices. These dynamic features enable the box to be reconfigured for different car widths, providing versatility while maintaining a single standardized design.
2Ease of manufacture
If the box is pre-assembled to match car width, then structural integrity is maintained, but assembly difficulty increases and handling becomes complex
Solution Approach 1:
The box is provided as separate modular components (lateral guide modules, connection module, grounding module) rather than a pre-assembled unit. This segmentation enables easier handling and assembly by a single operator while maintaining structural integrity through standardized connection interfaces with fixing members.
Solution Approach 2:
The modular components are designed with pre-defined assembly features including assembly orifices, complementary orifices, and fixing member locations. This preliminary preparation of connection points simplifies the assembly process while ensuring proper structural integrity when components are correctly assembled.
3Ease of operation
If access to wiring and connectors is provided only from the top, then the box structure remains simple, but assembly risk increases due to limited accessibility
Solution Approach 1:
The box structure incorporates lateral access through the connection module with its longitudinal passage opening that extends laterally. This adds a lateral dimension to access pathways, allowing operators to reach wiring and connectors from both top and lateral directions, improving accessibility without significantly complicating the overall box structure.
