Folding Bracket Mechanism for Compact Personal Vehicle Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric personal vehicles, such as scooters and bicycles, face challenges in transportability due to their size, weight, and difficulty in being folded into a compact form, making them hard to store and transport in urban areas, where space is limited and theft risk is high.
Innovation Solution
A folding system that allows personal vehicles to be quickly transformed from a driving position to a compact walking position, utilizing a pivotable bracket and handle mechanism, enabling easy transportation and storage by rolling on their own wheels, with a lock mechanism to secure the folded configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the vehicle structure is made compact and foldable, then transportability and storage ease are improved, but structural complexity increases
Solution Approach 1:
The vehicle frame is divided into multiple segments including handlebar assembly, deck, and wheel assemblies that can be independently folded and reconfigured. The handlebar assembly can be folded downward, the deck can be folded, and wheel assemblies can be detached, allowing the vehicle to transition from an extended operational configuration to a compact folded configuration for easy transport and storage.
2Weight of moving object
If the vehicle is designed to be lightweight for easy handling, then portability is improved, but structural strength may be compromised
Solution Approach 1:
The vehicle frame utilizes composite materials including aluminum alloy components and high-strength plastics to achieve an optimal balance between weight and structural strength. The aluminum alloy handlebar assembly and frame components provide sufficient strength for supporting rider weight and withstanding operational forces while keeping the overall vehicle weight low enough for easy portability and manual handling.
3Area of moving object
If the vehicle occupies more space for user comfort, then riding comfort is improved, but storage and transport difficulty increase
Solution Approach 1:
The vehicle incorporates dynamic folding mechanisms that allow it to transition between a large extended configuration for comfortable riding and a compact folded configuration for storage and transport. The handlebar assembly can be folded downward, the deck can be folded, and the overall footprint can be reduced, enabling the vehicle to adapt its spatial requirements based on whether it is being used for riding or stored/transported.

AI summary
A folding, personal vehicle includes a frame having a foot deck, a front wheel, a bracket, and a handle. The bracket is pivotally connected to the frame and has a bottom position and a top position. The handle is connected to the bracket and is positioned at least partially elevationally above the foot deck of the frame when the bracket is in the top position and is positioned at least partially elevationally below the foot deck of the frame when the bracket is in the bottom position. A folding mechanism for a personal vehicle includes a bracket with a first bracket profile and a second bracket profile. The first bracket profile engages a rear side of a bottom rod when the bracket is in a top position. The second bracket profile engages a front side of the bottom rod when the bracket is in a bottom position.
