Foldable Electric Vehicle With Multi-Point Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current foldable electric vehicles are inefficient and inconvenient to fold, especially in crowded environments, requiring the entire body to be laid down, which hinders quick and easy operation.
Innovation Solution
A foldable electric vehicle design incorporating a handlebar assembly, steering pole assembly, pedal assembly, and wheel assembly with multiple folding components, including hinged bars, sliding sleeves, locking mechanisms, and elastic members to facilitate easy and compact folding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the whole body of the electric vehicle is laid down and then folded, then the vehicle can be folded, but it causes great inconvenience to operate in a crowded environment and is not applicable to the circumstance where people are getting on and off against time
Solution Approach 1:
The electric vehicle is divided into multiple independently foldable segments: the first folding component divides the vehicle into a first portion and a second portion, the second folding component further divides into a third portion and a fourth portion, and the third folding component separates front and rear pedal frames. This segmentation allows each segment to be folded independently and simultaneously, enabling the entire vehicle to be folded quickly without requiring sequential folding of the whole body, thus reducing folding time and improving operational convenience in crowded environments.
2Productivity
If multiple folding components are added to enable easy folding, then the folding efficiency is improved, but the device complexity increases
Solution Approach 1:
The folding mechanism is segmented into three independent folding components, each with its own locking mechanism. This segmentation allows each component to be designed and optimized separately, making the overall system more manageable despite the increased number of parts. Each folding component handles a specific portion of the vehicle, distributing the folding task across multiple simple units rather than one complex mechanism.
Solution Approach 2:
Each folding component incorporates a locking mechanism that can dynamically transition between locked and unlocked states. The locking mechanisms engage to secure the folded position and disengage to allow folding, providing dynamic control over the folding process. This dynamic capability enables quick, controlled folding operations without requiring complex continuous motion mechanisms.
