Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing folding electric scooters have complex and time-consuming folding and unfolding mechanisms, making them inconvenient for users, especially those with mobility difficulties.
Innovation Solution
A folding scooter frame design featuring a linkage rod system that connects the front and rear frames, allowing the linkage rod to swing and drive a slider to slide, simplifying the folding and unfolding process through a pivotally connected seat support frame, along with a locking mechanism for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual folding mechanism with multiple steps is used, then the scooter can be folded, but the folding operation becomes complex and time-consuming
Solution Approach 1:
The patent combines multiple folding operations into a single action by linking the front frame folding with the seat support frame folding through a linkage rod. When the front frame is folded, the linkage rod automatically drives the seat support frame to fold simultaneously, reducing the number of manual operations required and decreasing total folding time.
Solution Approach 2:
The linkage rod acts as an intermediary mechanism between the front frame and the seat support frame. It translates the motion of folding the front frame into corresponding motion of the seat support frame, automating the coordination between different folding components and eliminating the need for separate manual folding operations.
2Ease of operation
If multiple mechanisms are used for folding, then the scooter can be folded, but the structure becomes complicated
Solution Approach 1:
The patent merges the folding mechanisms of the front frame and seat support frame into a single integrated system through the linkage rod. This reduces the number of independent mechanisms required and simplifies the overall structure while maintaining the folding functionality.
Solution Approach 2:
The linkage rod serves multiple functions: it connects the front frame to the seat support frame, transmits folding motion, and coordinates the folding sequence. This multi-functionality reduces the need for separate dedicated mechanisms for each folding operation, thereby reducing overall structural complexity.
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 significantly reduces the complexity and time required for folding and unfolding, enhancing convenience and usability for all users, including those with mobility issues.
Implementation Method 1
a linkage rod, a front end of the linkage rod is pivotally connected with the front frame, and a rear end of the linkage rod is pivotally connected with a slider
Implementation Method 2
the slider is slidably disposed on the rear frame, and the linkage rod is urged to swing as the front frame is folded, thereby driving the slider to slide
Implementation Method 3
the locking member is provided with a first locking position and a second locking position. Moreover, the locking bar is disposed at the rear frame. When folding, the locking bar is engaged with the first locking position of the locking member, alternatively when unfolding, the locking bar is engaged with the second locking position of the locking member
