Retrofitted Bus Interior With Progressive Floor Elevation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing buses face issues of outdated safety features, limited passenger comfort, and inefficient space utilization, with solutions like double-decker buses requiring significant capital investments and luxury coaches failing to address fundamental concerns.
Innovation Solution
A retrofitted bus design incorporating a progressive floor elevation system, elevated seating assemblies, stowage space, engine safety cover, swing-down egress mechanism, and roof-mounted air safety system, which can be installed on existing buses to enhance safety and comfort without replacing the entire fleet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If double-decker buses are introduced to increase passenger capacity and improve visibility, then passenger experience is improved, but height restrictions and capital investment requirements worsen
Solution Approach 1:
The bus interior is segmented into multiple levels through the progressive floor elevation system, creating distinct seating zones (first level seats near entrance, second level seats toward rear) without requiring a complete double-decker structure. This segmentation provides improved capacity and visibility while avoiding the complexity of full double-decker implementation.
Solution Approach 2:
The patent introduces vertical dimensionality through elevated flooring sections and raised seating assemblies, transforming the traditional single-level bus interior into a multi-level configuration. This dimensional change improves passenger capacity and visibility without requiring the extreme height of full double-decker buses.
2Ease of operation
If luxury coaches are developed to provide premium amenities and improve comfort, then user satisfaction is improved, but fundamental safety concerns and cost accessibility worsen
Solution Approach 1:
The patent applies local quality improvements through elevated seating assemblies with enhanced comfort features (cushions, headrests, armrests) and targeted safety enhancements (engine safety cover, swing-down egress mechanism) at specific locations within the bus, rather than requiring a complete luxury coach transformation. This provides improved comfort while maintaining safety and cost-effectiveness.
3Reliability
If existing bus fleets are replaced with new vehicles to improve safety and comfort, then passenger experience is improved, but capital investment and fleet obsolescence worsen
Solution Approach 1:
The patent implements preliminary safety actions by installing protective features (engine safety cover, swing-down egress mechanism, roof-mounted air safety system) and comfort improvements (progressive floor elevation, elevated seating) onto existing bus fleets before they reach obsolescence. This extends the service life and improves safety/comfort of current assets without requiring immediate fleet replacement.

AI summary
A retrofitted bus featuring a progressive floor elevation system that gradually increases the height of modular flooring sections from front to rear, creating additional underfloor storage space and improving passenger visibility. The bus incorporates elevated passenger seating assemblies with rigid support structures and adjustable footrests for enhanced comfort and accessibility. The retrofitted stowage space may include insulation, climate control, and video monitoring systems. An engine safety cover, constructed from fire-resistant, thermally insulating, and structurally reinforced materials, integrates an extinguishing system for fire suppression. A swing-down egress mechanism at the rear of the bus serves as a structural component during normal operation and converts to an evacuation slide or stairs during emergencies.
