Autonomous E-Bicycle Track Stand and Self-Repositioning Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transportation solutions for short distances within city centers are often inconvenient, inflexible, and costly, with traditional public transport lacking coverage, taxis being expensive and traffic-prone, and bikeshare services requiring extensive infrastructure and maintenance.
Innovation Solution
An autonomous electronic bicycle system that provides on-demand transportation by dispatching self-repositioning bicycles equipped with direct drive motors and advanced sensor systems, allowing riders to pedal manually after autonomous navigation to their destination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bikeshare services saturate the service area with many static pickup points and vehicles, then service availability is improved, but infrastructure cost and maintenance expense increase significantly
Solution Approach 1:
The bicycle transitions from a static parked state to a dynamic autonomous moving state, allowing the same vehicle to serve multiple locations sequentially. The bicycle can autonomously navigate to different pickup points based on demand, replacing the need for simultaneous presence at multiple static locations with a single dynamic vehicle that moves between locations as needed.
Solution Approach 2:
The bicycle autonomously repositions itself without requiring manual intervention or infrastructure support. The self-balancing mechanism and autonomous navigation system enable the vehicle to service itself by moving between locations independently, eliminating the need for human operators or complex infrastructure management.
2Quantity of substance
If traditional public transportation is used, then large numbers of people can be transported, but service coverage and flexibility to specific locations are reduced
Solution Approach 1:
The transportation system is segmented into multiple autonomous bicycles that can operate independently. Each bicycle serves as an individual unit that can be dispatched to specific locations based on demand, providing flexible point-to-point service while collectively transporting multiple passengers across the service area.
Solution Approach 2:
The system changes the operational parameters from fixed-route, high-capacity public transport to on-demand, flexible-location autonomous bicycles. By adjusting the deployment density and distribution of bicycles across the service area, the system achieves both adequate passenger capacity and flexible location coverage.
3Ease of operation
If taxi or rideshare services are used for short trips, then door-to-door transportation is provided, but cost increases and traffic congestion worsens
Solution Approach 1:
The system replaces the driver-operated mechanical transportation system with an autonomous electric bicycle system. The direct drive hub motors provide efficient electric propulsion, substituting the combustion engine and driver control mechanism with automated electronic control and electric power delivery.
Solution Approach 2:
The system changes key operational parameters including vehicle size (from cars to bicycles), power source (from combustion to electric), and control mode (from manual to autonomous). These parameter changes enable door-to-door service for short trips while reducing energy consumption and traffic impact through smaller, more efficient vehicles.

AI summary
An autonomous electronic bicycle comprises a frame, a front wheel that can be powered by a first electronic motor, a rear wheel that can be powered by a second electronic motor, and handlebars that can steer the front wheel which can be controlled by a third electronic motor. The autonomous electronic bicycle can operate autonomously, traveling to a chosen destination. When operating autonomously the autonomous electronic bicycle can shift between a set of balance modes, including a mode used when moving and a mode used when stationary but balanced. To transition between modes, a transition sequence of control commands can be selected and used.
