Convertible Scooter with Pivotable Supporting Arm for Dual Usage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scooters with seats face constructional challenges and limited use when trying to maintain functionality as both a conventional scooter and a training bicycle, as the addition of a seat complicates the design and restricts standing position usage.
Innovation Solution
The supporting arm connected to the footboard is pivotably coupled to the guide bearing about an axis through the center of the rear wheel, allowing a 180° rotation for two usage positions, enabling the scooter to be used with a seat without compromising its conventional operation and allowing conversion into a training bicycle mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a seat is fixed to the supporting arm connecting the footboard with the guide bearing, then the scooter can be used with a seat, but the use of the scooter in a standing position is limited and additional constructional measures are required
Solution Approach 1:
The supporting arm is made dynamically reconfigurable through a locking mechanism that allows it to be pivoted between a first usage position (for conventional scooter use with footboard) and a second usage position (for training bicycle use with seat). This dynamic reconfiguration enables the same structure to serve multiple functions without requiring separate fixed installations for each mode.
Solution Approach 2:
The scooter is divided into separable functional modules: the supporting arm with seat can be independently positioned and locked relative to the guide bearing, while the footboard remains attachable to the supporting arm. This segmentation allows the seat-carrying supporting arm to be selectively activated without permanently compromising the conventional scooter configuration.
2Adaptability or versatility
If the supporting arm is made pivotable for dual usage positions, then versatility is improved, but the stability and consistent handling may be affected
Solution Approach 1:
The supporting arm transitions from a static to a dynamically adjustable component, allowing it to be locked in either the first usage position (conventional scooter) or the second usage position (training bicycle). The locking mechanism ensures that once positioned, the supporting arm remains stable and secure, maintaining handling consistency within each mode while enabling versatility across modes.
Solution Approach 2:
The locking mechanism is designed to maintain the supporting arm in its selected position without requiring continuous external intervention. Once locked, the mechanism self-maintains the position against operational forces, ensuring stable handling in both usage configurations without compromising structural integrity.

AI summary
A scooter or bicycle including a chassis is provided. The chassis has a guide bearing for a steering column holding a front wheel and for a supporting arm for a pivotable footboard having a rear wheel. The supporting arm includes a seat. The supporting arm, connected to the pivotable footboard, is pivotally coupled to the guide bearing. A portion of the chassis including the supporting arm and the pivotable footboard is transferable from a first usage position as a scooter, in which the pivotable footboard is substantially parallel with the road surface, by a rotation of 180° around an axis of the supporting arm into a usage position as a bicycle, in which the pivotable footboard supports the supporting arm facing rearwardly from the steering column. The seat is arranged on a side of the supporting arm facing away from the pivotable footboard.
