Motorized Cycle with Collapsible Frame for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motorized scooters face challenges in compact storage and transportation, and they often lack sufficient cargo space, making them difficult to use comfortably and efficiently for carrying items like shopping bags.
Innovation Solution
A motorized cycle with a rigid frame that can retract into a collapsed position for easy storage and transportation, featuring a telescopic rear end for additional storage, a steering mechanism with fixed handlebars, and a motor connected to a battery and throttle switch, along with a resilient suspension system for comfort and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the scooter is designed with a rigid frame and fixed components, then structural strength and stability are improved, but transportability and storage convenience deteriorate
Solution Approach 1:
The scooter frame is divided into separable components including a main frame and a removable extension frame. The extension frame can be detached and stored separately, allowing the main frame to be compacted for storage while maintaining structural integrity during operation. This segmentation enables the scooter to transition between a compact storage state and a structurally sound operating state.
Solution Approach 2:
The scooter incorporates telescopic frame elements that can dynamically adjust between extended and retracted positions. The frame includes movable joints and locking mechanisms that allow the structure to transform from a compact configuration for storage to an extended configuration providing structural strength during operation, enabling adaptive structural properties.
2Quantity of substance
If the scooter frame is extended to provide cargo storage space, then cargo capacity is improved, but vehicle compactness and storage ease deteriorate
Solution Approach 1:
The cargo storage system is segmented into an integrated storage compartment within the main frame and a separate removable extension frame. The extension frame can be attached when cargo capacity is needed and removed or collapsed when compact storage is required, allowing the scooter to adapt between providing maximum cargo space and maintaining compact dimensions for easy storage.
Solution Approach 2:
The frame includes telescopic sections with locking mechanisms that allow dynamic adjustment of frame length. When extended, the frame provides additional cargo carrying capacity; when retracted, it returns to a compact configuration for easy storage, enabling the vehicle to dynamically adapt its volume to match storage or cargo needs.
3Ease of operation
If the scooter is designed with collapsible frame sections, then storage convenience is improved, but structural reliability and ride stability deteriorate
Solution Approach 1:
The collapsible frame is divided into rigid main frame sections and removable extension sections. The main frame maintains permanent rigid structural elements that ensure reliability during operation, while the extension sections can be collapsed or removed for storage. This segmentation allows the critical structural components to remain rigid and reliable while non-critical sections provide collapsibility for storage convenience.
Solution Approach 2:
The frame incorporates telescopic sections with positive locking mechanisms that maintain rigid structural integrity when extended for operation. The locking mechanisms ensure that when the frame is in its operational extended state, it provides reliable structural support, while allowing easy transition to a collapsed state for storage, thus dynamically adjusting between reliability and storage convenience.

Function Achieved in This Case
The solution provides a compact, easy-to-transport, and comfortable vehicle with enhanced cargo capacity, inhibiting theft through a key-locked on/off switch and ensuring ease of use with adjustable suspension and braking mechanisms.
Implementation Method 1
The resilient suspension member is preferably at least one spring shock absorber or at least one elastomeric cushion fixed between the rear cross member and the extension frame cross member for cushioning the frame from impacts to the rear wheels
Implementation Method 2
The resilient suspension member is preferably at least one spring shock absorber

AI summary
A vehicle for a person to ride on a ground surface includes a rigid frame that has front and rear ends and at least a seat on a top side of the frame. A steering mechanism disposed proximate the front end of the frame is adapted for allowing the person to steer a front wheel. A steering fork may include two lower fork members each selectively detachable from two upper fork members of the steering fork at two telescoping attachment arrangements that includes a front suspension arrangement. A rigid frame extension has a front end that is pivotally fixed proximate the rear end of the frame. The frame extension includes at least one rear wheel fixed with a rear end of the frame extension. A motor is fixed with the front wheel and is electrically connected with at least one battery and a throttle switch fixed with the steering mechanism.
