Engineering Contradiction Analysis
1Area of stationary object
If narrow-width personal transportation vehicles are used, then road space usage is minimized, but vehicle stability deteriorates
Solution Approach 1:
The patent introduces stabilization rails as intermediary elements that engage with the narrow-width vehicles to provide lateral support. These rails act as mediators between the vehicle and the track infrastructure, enabling narrow vehicles to maintain stability without requiring wider dimensions. The stabilization mechanism includes rails positioned at strategic locations that prevent vehicle overturning while preserving the narrow profile.
Solution Approach 2:
The vehicle stability system is segmented into multiple independent components: stabilization rails positioned at different locations, engagement mechanisms with specific geometric features, and modular support structures. This segmentation allows the narrow vehicle body to be supported by distributed contact points rather than requiring a wide base, thereby maintaining stability with minimal road space occupation.
2Productivity
If dedicated rail infrastructure is built, then transportation efficiency is improved, but infrastructure cost and complexity increases
Solution Approach 1:
The rail infrastructure is designed with multi-functionality to serve both guidance and stabilization purposes simultaneously. The same rail structure provides lateral support for vehicle stability while also defining the travel path for guidance. This universal design eliminates the need for separate guidance mechanisms and reduces overall infrastructure complexity compared to traditional dedicated rail systems.
Solution Approach 2:
The patent merges the guidance function and stabilization function into a single integrated rail system. Rather than having separate tracks for guidance and separate structures for stabilization, the design combines these functions into one infrastructure element, thereby reducing the number of components and simplifying the overall system while maintaining transportation efficiency.
3Quantity of substance
If traditional public transport vehicles are used, then passenger capacity is increased, but road congestion and travel time worsen
Solution Approach 1:
The passenger transport system is segmented into multiple narrow-width personal vehicles traveling in coordinated formation or along the same track infrastructure. Instead of one large bus occupying a wide lane and making multiple stops, multiple smaller vehicles can travel more efficiently, accessing different stops simultaneously and reducing overall travel time while collectively accommodating similar passenger capacity.

AI summary
Personal transportation system includes plurality of personal transportation vehicles (PTVs) driven on a track network with series of track sections. PTV main section has lateral width adapted to contain single occupant. PTV driving mechanism propels PTV and includes track engaging element protruding downwards from main section and having narrow lateral width such that main section is prone to fall over when PTV is at rest. The space between lateral width of main section and track engaging element can be occupied by public infrastructure. Each track section includes a ground portion, minimally adapted to accommodate track engaging element lateral width, and an empty space above ground portion, free of non-transient obstacles and minimally adapted to accommodate main section lateral width. A guidance mechanism guides PTV along track network and prevents PTV deviating from track sections. A stabilization mechanism stabilizes PTV along track network and prevents PTV from falling over when turning/merging/diverging.
