Rotating Scooter Seat Unit with Elastic Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional children's scooters have a seat that occupies too much space when folded and lacks aesthetic appeal, as the folded seat does not integrate well with the handrail, limiting activity space and visual design.
Innovation Solution
A scooter design featuring a rotatable seat unit that converts into a handrail, utilizing a locking mechanism with elastic units and cavity structures to securely transition between seat and handrail positions, allowing for dual-purpose functionality and easy switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the seat is folded to one side of the handrail, then the seat can be stored when not in use, but the folded seat still occupies player's activity space and is not aesthetically pleasing
Solution Approach 1:
The patent merges the folded seat with the handrail structure by making the seat rotatably connected to the handrail, allowing the seat to integrate into the handrail when folded. This combination eliminates the need for separate storage space and improves aesthetic appearance while maintaining adaptability.
Solution Approach 2:
The handrail structure is designed to serve dual functions: as a support structure when the seat is in use, and as an integrated storage position for the folded seat. This multi-functionality allows the same structural element to fulfill multiple purposes, reducing overall space requirements.
2Adaptability or versatility
If the seat is folded to one side of the handrail, then the seat can be stored when not in use, but the folded seat is not aesthetically pleasing
Solution Approach 1:
The patent merges the folded seat with the handrail structure by making the seat rotatably connected to the handrail, allowing the seat to integrate into the handrail when folded. This combination eliminates the need for separate storage space and improves aesthetic appearance while maintaining adaptability.
3Reliability
If a locking mechanism is added to secure the seat unit, then the seat positioning reliability is improved, but the device complexity increases
Solution Approach 1:
The locking mechanism utilizes the weight of the seat unit itself and the elastic force of the first elastic unit to automatically engage and disengage the lock head with the cavity body. This self-service approach eliminates the need for additional actuators or complex control systems, maintaining simplicity while ensuring reliable positioning.
Solution Approach 2:
The patent replaces complex mechanical locking systems with a simpler elastic-based locking mechanism. The first elastic unit provides the necessary locking force through its elastic deformation, substituting for more complex mechanical actuators or multi-component locking systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design provides a compact, safe, and aesthetically pleasing solution by allowing the seat to fold into a stand column and handrail, offering a convenient and integrated handrail system while maintaining a simple structure.
Implementation Method 1
a first elastic unit is arranged between the lock head and the main body of the scooter
Implementation Method 2
a second elastic unit is arranged in the built-in cavity, the second elastic unit includes a pin head arranged at the through hole

AI summary
Disclosed is a scooter, including a seat unit, rotatably arranged on a main body of the scooter and including a first position as a seat after being unfolded and a second position as a handrail after being folded; and a locking unit, arranged on the main body of the scooter, the locking unit positioning the seat unit when the seat unit is in the first position and the second position. In the present disclosure, the seat unit matches with a handrail unit to provide a dual-purpose mode. The seat unit, when unfolded, serves as a seat, and the handrail unit serves as a handrail.
