Straddle Monorail Escape Passage Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Straddle-type monorail trains face high costs, large occupied space, and stability issues due to the complex structure of their escape passages, which include additional frames and floors that increase weight and space requirements.
Innovation Solution
A rail transport system with a rail vehicle design where compartments are hinged sequentially along the rail, with bogies straddling the rail and forming an integrated escape passage, reducing the need for additional structures and minimizing weight and space occupancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional frames and floors are provided to form an escape passage on the rail, then passenger evacuation capability is improved, but device complexity and construction costs increase
Solution Approach 1:
The escape passage is merged with the rail structure itself. The rail is designed with an integrated escape passage that forms part of the rail's cross-sectional structure, eliminating the need for separate frames and floors. This integration reduces device complexity while maintaining evacuation capability.
Solution Approach 2:
The rail structure serves multiple functions: it provides structural support for the monorail system and simultaneously serves as an integrated escape passage for passenger evacuation. This multi-functionality eliminates the need for dedicated escape structures, reducing overall complexity.
2Reliability
If frames and floors are laid on the rail to form an escape passage, then evacuation capability is improved, but the occupied space increases
Solution Approach 1:
The escape passage is combined within the rail's cross-sectional area rather than being added as external structures. The rail's internal structure is configured to provide an escape route, ensuring that the escape passage occupies space that would otherwise be structural material, thereby minimizing additional occupied space.
3Reliability
If frames and floors are erected on the rail for escape passage, then evacuation capability is improved, but the weight borne by the rail increases, adversely affecting stability
Solution Approach 1:
The escape passage is integrated into the rail's structural cross-section, meaning the materials used for the escape passage are part of the rail's load-bearing structure. This eliminates the need for additional weight-bearing frames and floors, maintaining rail stability.
Solution Approach 2:
The rail's cross-sectional parameters are modified to incorporate the escape passage. By changing the internal configuration of the rail's cross-section, the escape passage is formed without adding external weight, as the escape structure becomes part of the rail's own material composition.
