Backpack Self-Balancing Scooter Foot Steering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional self-balancing scooters require riders to use their hands for steering, limiting hand freedom and making them bulky for storage and transportation.
Innovation Solution
A backpack type self-balancing scooter with a foot-driven steering apparatus, featuring a dialing shuttle ring operated by the rider's foot, allowing hands-free steering and a compact design without traditional handles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manipulation handles are mounted on the scooter for steering control, then steering functionality is achieved, but the scooter becomes bulky and hands are not freely usable
Solution Approach 1:
The patent removes the traditional manipulation handles from the scooter structure and extracts the steering function to be performed by the rider's foot through the shuttle ring mechanism. This extraction eliminates the bulky handle structure while maintaining steering capability, directly resolving the contradiction between hand freedom and scooter volume.
Solution Approach 2:
The footrest platform is given multiple functions: it serves as both a support surface for the rider's feet and as the operational interface for steering control through the shuttle ring. This multi-functionality eliminates the need for separate handling components, reducing overall scooter volume while maintaining full steering capability.
2Ease of operation
If manipulation handles are mounted on the scooter for steering control, then steering functionality is achieved, but the scooter becomes bulky for storage and transportation
Solution Approach 1:
The steering function is extracted from the traditional handlebar structure and repositioned to the footrest area where the shuttle ring is operated by the foot. This extraction eliminates the need for bulky manipulation handles while preserving complete steering control functionality, making the scooter more compact for storage and transportation.
Solution Approach 2:
The steering control interface is moved from the upper dimension (hand-operated handles) to the lower dimension (foot-operated shuttle ring on the footrest). This dimensional transition allows the scooter to maintain full steering capability with a significantly reduced profile and volume.
3Volume of moving object
If the scooter is designed with a compact shape for easy carrying, then portability is improved, but traditional handling for steering is lost
Solution Approach 1:
The footrest platform is designed as a multi-functional element that simultaneously provides rider support and serves as the steering control interface through the shuttle ring mechanism. This allows the scooter to maintain a compact form factor while preserving complete steering functionality through foot operation.
Solution Approach 2:
The rider's foot, which naturally rests on the footrest for support, is also used to operate the steering function through the shuttle ring. This self-service approach eliminates the need for separate handling components, allowing the scooter to remain compact while maintaining full steering capability through the rider's own body movements.

AI summary
A backpack type self balancing scooter having a foot-driven steering apparatus mounted thereon is provided, including: two wheels having motors mounted thereon; a motor housing for mounting the motors therein in such a manner as to allow rotary shafts of the motors to be located linearly to each other; a footrest; a shuttle ring mounted on any one side of the footrest; an erecting housing, a controller mounted on the upper portion, a cover disposed coveringly on top thereof, and an insertion hole formed on the center of the cover; a saddle; and a backpack. The rider walks in the state of carrying the backpack on the back, or puts the backpack on the around, sits on the saddle to drive the self balancing scooter in the state where both hands are free, while conducting the direction changes through the shuttle ring turned with his or her foot.
