Solution Overview

Problem

Catering areas in railway vehicles often have limited space, making them inaccessible to people with reduced mobility, who are thus excluded from conviviality zones and services like refueling facilities and toilets.

Innovation Solution

Designing a car with a central zone that includes a spacious catering area with wide access doors, a flat floor, and a corridor layout allowing easy passage for two people in wheelchairs, along with universal toilets and automatic refueling installations, ensuring all passengers can access and move freely within the catering space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the catering area is designed with limited space to fit within the vehicle carriage, then the vehicle structure remains compact and efficient, but accessibility for people with reduced mobility is compromised

Engineering Contradiction:
Improvecatering area spaceVSAvoidaccessibility for people with reduced mobility
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The catering area is segmented into distinct functional zones: a service counter area for transactions, a dedicated corridor for wheelchair passage, and seating areas. This segmentation allows the limited space to be efficiently organized while ensuring that the corridor provides adequate access and maneuverability for people with reduced mobility without compromising the overall compactness of the vehicle carriage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The corridor adjacent to the refueling facility is designed with locally enhanced properties: increased width and improved flooring characteristics specifically in the access pathway. This local quality improvement ensures that people with reduced mobility can easily access the catering area and maneuver within it, while the rest of the catering area maintains its compact efficient layout for general use.

Inventive Principle:
Principle #3Local quality

2Device complexity

If the catering area is designed without a counter managed by employees, then the layout becomes simpler and more accessible, but service delivery mechanisms must be fundamentally rethought

Engineering Contradiction:
Improvecatering area layoutVSAvoidservice accessibility
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The catering area is designed as a self-service facility where customers can directly access refueling facilities and obtain food and beverages without requiring employee assistance behind a counter. This eliminates the need for a traditional employee-managed counter, simplifying the layout and improving accessibility for people with reduced mobility who can independently navigate and use the facilities.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The catering area is designed with universal accessibility features that serve all customers regardless of mobility requirements. The same corridor and access points serve both wheelchair users and able-bodied passengers, and the self-service refueling facilities provide the same functionality to all users, creating a universally accessible environment without requiring separate service mechanisms.

Inventive Principle:
Principle #6Universality (Multi-functionality)
