Elevated Train Circumambulation for Mobility Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The Grand Mosque in Mecca experiences large crowds during the Hajj pilgrimage, making it difficult for individuals in wheelchairs and with mobility issues to perform the ritual of tawaf around the Kaaba, as existing systems do not adequately facilitate their movement.
Innovation Solution
A train system with elevated tracks forming a closed loop around the Kaaba, featuring electric trains with adjustable seating heights and platforms for easy embarkation and disembarkation, allowing individuals with mobility issues to circumambulate the site without obstructing other pilgrims.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional ground-level path is used for circumambulation, then accessibility for all pilgrims is maintained, but people with mobility issues cannot effectively perform the ritual due to crowd obstruction and physical barriers
Solution Approach 1:
The patent introduces an elevated three-dimensional circumambulation path above the ground level, allowing pilgrims with mobility issues to circumambulate the Kaaba without interacting with the crowded ground level. This vertical dimension separation resolves the contradiction by providing accessible ritual performance while maintaining ground-level pilgrimage activities uninterrupted.
Solution Approach 2:
The elevated platform acts as an intermediary structure that mediates between the needs of pilgrims with mobility issues and the ground-level crowd. It provides a dedicated circumambulation route that neither interferes with nor depends on the ground-level path, enabling independent ritual performance for elevated passengers.
2Ease of operation
If an elevated train system is introduced to help pilgrims with mobility issues, then accessibility and unobstructed views are improved, but the complexity of the system increases
Solution Approach 1:
The elevated train system serves multiple functions simultaneously: it provides circumambulation for pilgrims with mobility issues, offers elevated viewing platforms, and maintains a closed-loop transport system that can operate independently. This multi-functionality justifies the increased system complexity by delivering comprehensive solutions to multiple pilgrimage needs.
Solution Approach 2:
The circumambulation system is segmented into separate functional components: the elevated train for mobility-impaired pilgrims, ground-level paths for able-bodied pilgrims, and stationary elevated viewing platforms. This segmentation allows each component to be optimized independently, managing overall system complexity through modular functional separation.
3Ease of manufacture
If seats are positioned at uniform height in the train carriages, then manufacturing and maintenance are simplified, but pilgrims with different mobility needs cannot all achieve optimal viewing and comfort
Solution Approach 1:
The seating arrangement implements local quality variation within the train carriages, with seats positioned at different heights (first seats closer to the window at higher positions, second seats at lower positions) to accommodate pilgrims with different mobility needs. This localized differentiation optimizes viewing and comfort for each passenger while maintaining overall system functionality.

AI summary
A train system for moving people within a religious site includes an elevated train track forming a closed loop within the religious site. An object of attention is located at a middle of the closed loop. The train system also includes at least one train on the elevated train track, at least one passenger platform for embarkation of at least one passenger onto the train, and at least one passenger platform for disembarkation of the at least one passenger from the train. The at least one train includes at least one carriage has an inside having a floor, a first seat located closer to the object of attention, and a second seat next to the first seat and farther away from the object of attention. The first seat and second seat have different distances from the floor of the carriage.
