Modular Toilet Cabin Standardized Panel Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Developing separate toilet cubicles for individuals with reduced mobility and able-bodied individuals for railway vehicles incurs significant development costs, as each type requires independent design and development.
Innovation Solution
A modular toilet cubicle design featuring a standardized rear wall and functional panel that can be adapted for both universal and standard cubicles by adding specific additional walls, with the majority of functional components carried by the panel to minimize structural modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate toilet cubicles are designed for able-bodied people and persons with reduced mobility, then each type can be optimized for its specific user needs, but development costs increase significantly due to independent design and development of each type
Solution Approach 1:
The toilet cubicle is divided into a standardized base structure (walls, floor, ceiling, door, functional panel) and variable components (additional walls, grab bars, toilet bowl type). This segmentation allows the core structure to be reused across different cubicle types while only modifying specific segments to meet different accessibility requirements.
Solution Approach 2:
The patent creates a universal base design that serves both able-bodied users and persons with reduced mobility. The standardized functional panel, wall structure, and layout provide universal functionality, while optional additional walls and modified door configurations enable the same base design to adapt to different user needs without requiring completely separate designs.
2Ease of manufacture
If a standardized base design is used for both universal and standard cubicles, then development costs are reduced through component reuse, but the ability to optimize for specific user needs may be compromised
Solution Approach 1:
The design incorporates dynamic adaptability through optional configuration elements. The base structure remains standardized, but additional walls can be added or removed, door positions can be modified, and grab bars can be installed as needed. This dynamic approach allows the same standardized base to be customized for specific user requirements while maintaining manufacturing efficiency.
Solution Approach 2:
The patent applies local quality by making specific modifications only where needed rather than redesigning the entire cubicle. The standardized base provides uniform quality across all cubicles, while local variations (additional walls for privacy, modified door locations, specific grab bar placements) are implemented only in the areas required to meet specific accessibility or user preference requirements.
