Moving Walkway Seat Loop With Linear Motor Propulsion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing moving walkways lack the ability for passengers to sit while riding, making it difficult for individuals who cannot walk or stand for long durations.
Innovation Solution
A seat system for moving walkways that includes seat apparatuses with a propulsion system using linear motors and permanent magnets, supported by a frame, allowing seats to move in a horizontal or vertical loop, with transition zones for seamless direction changes, and controlled by a computer system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If moving walkways are designed only for standing, then the structure remains simple, but accessibility for those who cannot walk or stand long distances is limited
Solution Approach 1:
The moving walkway system is divided into separate functional modules: standing-only sections and seated sections. The seat apparatus is implemented as an independent module that can be integrated into specific segments of the moving walkway, allowing selective seating availability without redesigning the entire system.
Solution Approach 2:
The moving walkway is designed to serve multiple functions: it can accommodate both standing passengers and seated passengers. The seat apparatus is designed to be compatible with the existing moving walkway infrastructure, allowing the same system to provide both standing and seated travel options.
2Ease of operation
If seat apparatuses are added to moving walkways, then passenger comfort is improved, but the propulsion system and frame structure become more complex
Solution Approach 1:
The seat apparatus is merged with the existing moving walkway propulsion system. The same linear motors and track infrastructure that propel the walkway belt also propel the seat apparatuses, eliminating the need for separate propulsion systems and reducing overall complexity.
Solution Approach 2:
The seat apparatuses utilize the existing moving walkway infrastructure for their propulsion. The linear motors embedded in the walkway structure provide propulsion for both the belt and the seats, making the system self-sufficient and reducing the need for additional external propulsion components.
3Productivity
If seat apparatuses travel around a loop track, then continuous circulation is achieved, but the return side enclosure adds structural complexity
Solution Approach 1:
The seat apparatuses are nested within the existing moving walkway frame structure during their return trip. The frame enclosure that already exists for the moving walkway belt is utilized to house the return-side seat apparatuses, eliminating the need for separate enclosure structures.
Solution Approach 2:
The moving walkway frame structure serves multiple functions: it provides structural support for the belt, encloses the return-side seat apparatuses, and guides the circulation path. This multi-functional design reduces the need for additional specialized structural components.
