Triangular Partition Wall for Wheelchair Cabin Accessibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional train coach layouts with wheelchair-accessible cabins located at the extremities face challenges in providing sufficient space for wheelchair users to turn and access cabins, often resulting in increased aisle widths or oversized doors that compromise cabin space.
Innovation Solution
A train coach layout featuring a partition wall section arranged in a triangular shape extending from the corridor towards a cabin accessible by wheelchair, allowing for a wider doorway and minimizing space loss, enabling wheelchair accessibility anywhere along the coach, including the middle section.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the aisle width is increased to allow wheelchair access to cabins, then wheelchair accessibility is improved, but the space available for compartments is reduced
Solution Approach 1:
The patent introduces a triangular-shaped partition wall section that extends from the corridor towards the cabin, creating a three-dimensional turning space within the existing two-dimensional corridor footprint. This allows wheelchair users to perform turning maneuvers without requiring the corridor width to be increased, thereby maintaining compartment space while improving wheelchair accessibility.
2Ease of operation
If oversized doors are used to accommodate wheelchair access, then wheelchair accessibility is improved, but the compartment space is reduced and other problems arise
Solution Approach 1:
The triangular partition wall section is positioned in advance before the doorway, creating a dedicated turning area that allows wheelchair users to orient themselves properly before approaching the door. This preliminary positioning space eliminates the need for oversized doors, as wheelchairs can be maneuvered into the correct orientation using the triangular space, thereby preserving cabin space while ensuring accessibility.
3Ease of operation
If accessible cabins are located at the extremity of the train coach, then wheelchair access is simplified, but the layout flexibility and space utilization are reduced
Solution Approach 1:
The patent applies the triangular partition wall configuration specifically at locations where accessible cabins are positioned, rather than requiring all cabins to be at extremities. This localized adaptation allows accessible cabins to be placed anywhere along the coach length, providing layout flexibility while maintaining wheelchair accessibility through the dedicated turning space created by the triangular partition.

AI summary
A train coach layout adapted for wheelchair access to a cabin of a train coach includes a plurality of cabins. The location of the cabin is different from an extremity of the train coach. The train coach layout includes a partition wall section of the train coach arranged with a triangular shape extending from a corridor of the train coach towards the cabin accessible by wheelchair. Each of two adjacent cabins include one partition wall corresponding to one side of the triangular shape. The cabin also includes a cabin access door, has dimensions and orientations to both allow movement of wheelchair and minimize loss of space in cabin.
