Foldable Electric Scooter Frame with Removable Battery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric mobility vehicles (EMVs) are either bulky and difficult to transport, sacrificing stability for portability, or they are lightweight and unstable, failing to meet the needs of individuals with disabilities, recreational users, and industrial applications simultaneously while being aesthetically unpleasing and limited in functionality.
Innovation Solution
A three-wheel, foldable, battery-powered electric personal transporter with a dual beam support frame that allows easy folding into smaller components without tools, featuring a removable seat and battery pack for enhanced portability and stability, designed to accommodate both standing and sitting users, and suitable for various environments and uses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the EMV is designed to be lightweight for easy transport, then portability is improved, but stability deteriorates
Solution Approach 1:
The vehicle is divided into separable components including a removable battery pack and a foldable frame structure. The battery pack can be detached to reduce weight for transport, while the foldable frame allows the vehicle to be collapsed into a compact configuration. This segmentation enables users to optimize between weight and stability based on whether the vehicle is in use or being transported.
Solution Approach 2:
The vehicle incorporates a dynamic folding mechanism that transforms the rigid frame into a collapsible structure. The dual beam support frame with pivot points and locking mechanisms allows the vehicle to transition between an extended stable configuration for operation and a folded compact configuration for transport, dynamically adapting the structure to different operational requirements.
2Stability of the object's composition
If the EMV is designed to be bulky for stability, then stability is improved, but ease of transport deteriorates
Solution Approach 1:
The vehicle structure is segmented into modular components that can be folded and collapsed. The dual beam frame with pivot points allows sections to be folded relative to each other, reducing the overall footprint from a bulky stable configuration to a compact transport configuration, while maintaining structural integrity through locking mechanisms.
Solution Approach 2:
The vehicle employs dynamic folding mechanisms that enable transformation between extended and collapsed states. The pivot points and locking systems allow the frame to be easily folded by users without requiring tools, facilitating simple transport while maintaining stability during operation through the locked extended configuration.
3Volume of moving object
If the EMV uses a complex folding mechanism to reduce size, then portability is improved, but device complexity increases
Solution Approach 1:
The folding mechanism is segmented into discrete functional elements: pivot points at key joints, locking mechanisms at folding joints, and a dual beam frame structure. Each element performs a specific function, and the modular nature allows the complex folding action to be achieved through simple, tool-free operations at each segment rather than a single complex mechanism.
4Adaptability or versatility
If the EMV is designed to accommodate both standing and sitting users, then versatility is improved, but device complexity increases
Solution Approach 1:
The vehicle incorporates a removable seat that can be installed or detached based on user needs. The underlying platform and footrest area are designed to accommodate both standing and sitting positions, making the vehicle universally adaptable to different user preferences and requirements without requiring separate vehicle configurations.

AI summary
A three wheeled stand-up or sit down foldable and portable electric personal mobility vehicle for fulfilling the needs of a broad spectrum of users including the handicapped and recreational users. The personal mobility vehicle has two major parts, including a front wheel frame assembly and a rear frame chassis assembly. These major parts are configured to easily fold into a smaller size so that the vehicle can be easily transportable and more conveniently stored. Furthermore, a versatile seat and seat post are implemented to enable a user to sit or stand, and the seat can be easily removed, without tools, to create more space should a user wish.
