Transformable Electric Scooter Frame with Dual-Position Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transforming scooters lack a seamless and secure mechanism to transition between stand-on and ride-on configurations, often requiring complex folding mechanisms that can be cumbersome and prone to accidental unlocking during use.
Innovation Solution
A scooter design featuring a movable frame member that slides and locks at different positions on a fixed frame, allowing for easy conversion between stand-on and ride-on configurations, with a locking mechanism that includes a primary and secondary lock to ensure secure positioning in either mode, and a telescoping steering column for adjustable handlebar height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a folding mechanism is used to transform between stand-on and ride-on configurations, then the scooter can switch between configurations, but the mechanism becomes complex and prone to accidental unlocking
Solution Approach 1:
The scooter frame member is designed to be dynamically reconfigurable, allowing it to transition between a horizontal position (stand-on configuration) and an inclined position (ride-on configuration). This dynamic transformation enables the scooter to adapt between two distinct operational modes without requiring complex folding mechanisms, thereby resolving the contradiction between adaptability and device complexity.
2Reliability
If a locking mechanism is added to secure the frame position, then the scooter becomes more stable in each configuration, but the device complexity increases
Solution Approach 1:
The locking mechanism is designed to automatically engage and secure the frame member in either the horizontal or inclined position without requiring additional complex components or manual intervention. The mechanism self-activates during the transformation process, providing reliable configuration stability while minimizing the increase in device complexity.
3Ease of operation
If the frame member is made movable and slidable, then the transformation between configurations becomes easier, but the structural stability may be compromised
Solution Approach 1:
The frame member is designed with movable and slidable characteristics that enable easy transformation between configurations. The dynamic design allows the frame to move smoothly during transformation while maintaining structural integrity through proper engineering of the sliding interface and locking mechanism, thereby resolving the contradiction between ease of operation and structural stability.
4Volume of moving object
If the scooter is designed to fold for compact storage, then the storage space requirement decreases, but the device complexity increases
Solution Approach 1:
The scooter incorporates a dynamic folding capability that allows the frame member to transition between extended and compact positions. This dynamic design enables the scooter to fold into a compact configuration for reduced storage volume while integrating the folding function into the existing movable frame structure, thereby minimizing the increase in device complexity.

AI summary
An electric transformable scooter that can transform between a stand-on configuration and a ride-on configuration. The scooter has a fixed frame member at the front to which the front wheel and handlebar are mounted, and movable frame member that extends between the rear wheel and the fixed frame member. The front end of the movable frame member slides or otherwise adjusts to either a lower position or an upper position on the fixed frame member. When the movable frame member is at the lower position and locked thereat, it is generally horizontal, and its top surface defines a stand-on floorboard for stand-on operation. When the movable frame member is slid to its upper position and locked thereat, it is inclined from front to rear, and portion rotates away and locks thereat to become a seat for ride-on operation.
