Engineering Contradiction Analysis
1Ease of operation
If conventional disassemble and foldable scooter structures with outer tube tightly covering inner tube are used, then the scooter can be folded and disassembled, but the assembling processes become slower and more complicated
Solution Approach 1:
The patent applies nesting by having the outer tube tightly cover the inner tube, with the standing tube inserted into the roll tubes. This nested structure allows compact folding while enabling quick assembly through simple insertion and locking mechanisms rather than complex fastening procedures.
Solution Approach 2:
The scooter is divided into separable components (upper plate member, lower plate member, frames, standing tube, roll tubes) that can be independently assembled. The segmentation allows each component to be quickly connected through standardized interfaces like the hooking part and connection part, reducing overall assembly time and complexity.
2Ease of operation
If conventional foldable scooter structures are used, then the scooter can be folded, but the assembling processes are more complicated
Solution Approach 1:
The standing tube serves multiple functions: it provides structural support, acts as a locking mechanism through its hooking part, and enables pivotal connection to the roll tubes. This multi-functionality reduces the need for separate components, simplifying the overall structure while maintaining foldability and assembly ease.
Solution Approach 2:
The patent merges the frame structure with the folding mechanism by integrating the clip into the frame, which both supports the standing tube and enables the folding action. This combination reduces the number of separate parts and simplifies the assembly process.

AI summary
An electric scooter includes: an upper plate member including two roll tubes and a shaft tube pivotally connected to a standing tube and inserted into the roll tubes, the standing tube having a hooking part and a connection part disposed between the roll tubes and inserted by the shaft tube; a lower plate member including a pressing part positioning with the hooking part; two frames pivotally connected between the upper and lower plate members through bolts, each opened frame including a clip tightly covering the standing tube; a stopper disposed between the upper and lower plate members and positioning the closed frames; and a pivotal connection seat including two frame fitting members covering the tapered portions and having a quick release member, a tapered seat base having a top part combined with a cover frame of the seat cushion provided with a quick release member fixed to a positioning hole.
