Foldable Vehicle Frame Segmentation for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bicycles and scooters are bulky, making them inconvenient for urban short-distance travel and difficult to carry or store, especially in crowded urban areas where space is limited.
Innovation Solution
A foldable vehicle design featuring a front wheel frame and rear wheel frame that pivot against a central joint, allowing the vehicle to be compactly folded for storage in a backpack, with a handlebar assembly and seat assembly that can be easily secured and released for use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional bicycles and scooters are used, then they provide adequate mobility for urban travel, but they are bulky and difficult to carry and store
Solution Approach 1:
The vehicle frame is divided into multiple segments (front wheel frame, rear wheel frame, handlebar assembly, seat assembly) connected by pivot joints, allowing each segment to be independently positioned during folding and unfolding operations
Solution Approach 2:
The vehicle employs dynamic folding mechanisms with pivot joints that allow the frame segments to rotate and collapse from a rigid rideable configuration to a compact folded configuration, transforming the vehicle's spatial dimensions on demand
2Volume of stationary object
If the vehicle is made compact for easy storage, then it can be stored in a backpack, but it must be foldable with multiple joints and assemblies
Solution Approach 1:
The folded vehicle frame is designed to nest within a backpack, with the collapsed frame segments fitting inside the backpack's interior space, maximizing portability and utilizing the backpack as a containing structure
Solution Approach 2:
The handlebar assembly and seat assembly are separated as distinct components that can be independently folded and positioned, allowing them to be stored within the backpack when not in use

AI summary
A foldable vehicle includes a front wheel frame having a front wheel pivotably connected thereto, the front wheel frame having a front circular opening for receiving the front wheel. The vehicle also has a rear wheel frame having a rear wheel pivotably connected thereto, the rear wheel frame having a rear circular opening for receiving the rear wheel. A pivot joint connects the front wheel frame and the rear wheel frame, with the front wheel frame and the rear wheel frame being pivotable against each other via the pivot joint. A front vertical support extends from the front wheel frame and has a handlebar assembly pivotably secured to the front vertical support, and a rear vertical support extends from the rear wheel frame and has a seat assembly removably secured to the rear vertical support.
