Modular Cantilever Seat Mounting for Lightweight Train Interiors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seating arrangements for passenger transport vehicles, particularly commuter and regional trains, are heavy, require additional support from the side wall, and are often unique to a specific vehicle, necessitating modifications to the seat mounting structure or body shell.
Innovation Solution
A modular seating arrangement with a cantilever design featuring a support arm arrangement connected via axes, allowing easy interchangeability and flexibility, with components like first wall brackets and support arms that can be decoupled without unscrewing, and adjustable seat mounting elements for different configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If traditional seat mounting structures are used, then the seating arrangement is stable and strong, but the weight is high and flexibility is reduced
Solution Approach 1:
The support arm arrangement is divided into separate modular components: wall brackets, support arms, and axes that can be independently assembled and disassembled. This segmentation enables the seating arrangement to be lightweight yet adaptable to different vehicle types without requiring heavy integrated structures.
Solution Approach 2:
The wall brackets are designed as universal components that can be mounted on vehicle walls using standardized connection elements. The modular support arm arrangement can be configured for single, double, or four-seat configurations, providing multi-functionality across different vehicle types without requiring vehicle-specific modifications.
2Ease of operation
If modular design with quick-release mechanisms is used, then ease of assembly and disassembly is improved, but device complexity increases
Solution Approach 1:
The support arm arrangement uses segmented components connected by axes that can be quickly inserted and removed. The wall brackets, support arms, and connection elements are separate modules that simplify assembly and disassembly operations while maintaining structural integrity during use.
Solution Approach 2:
Connection elements act as intermediaries between the wall brackets and support arms, enabling quick attachment and detachment without complex fastening mechanisms. These standardized intermediaries simplify the assembly process while the overall system remains relatively simple in design.
3Productivity
If standardized components are used, then manufacturing cost is reduced and productivity is improved, but adaptability to different vehicle configurations is limited
Solution Approach 1:
The seating arrangement uses standardized segmented components that can be quickly assembled in different configurations. The modular wall brackets and support arms enable rapid exchange and assembly for single, double, or four-seat configurations, improving productivity while maintaining adaptability through combinatorial flexibility.
Solution Approach 2:
The support arm arrangement incorporates pivotable connections via axes, allowing dynamic adjustment and reconfiguration of seat positions. This dynamic capability enables standardized components to adapt to different vehicle configurations while maintaining quick assembly and exchange capabilities.
