Motorized Extendable Chassis for Cargo Capacity and Maneuverability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric vehicles and electric bikes are limited in cargo capacity, power provision, and adaptability to regulatory requirements, making them inefficient for cargo deliveries and long commutes.
Innovation Solution
An electrically powered vehicle with an extendable chassis that includes a rear chassis for carrying cargo boxes, powered by a chassis motor and electrical wiring, allowing for configuration changes to meet regulatory adaptability and cargo needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the chassis is extended to increase cargo capacity, then the cargo load capacity is improved, but the vehicle size increases making it less suitable for bicycle lanes
Solution Approach 1:
The patent implements a motorized extendable chassis that can dynamically change its length between extended and retracted positions. The chassis includes a movable section that can be extended to increase cargo capacity or retracted to reduce vehicle size for navigating bicycle lanes and tight spaces, allowing the vehicle to adapt to different operational requirements
2Quantity of substance
If the chassis is extended to carry more cargo boxes, then the cargo capacity is improved, but the vehicle becomes less maneuverable in traffic
Solution Approach 1:
The motorized extendable chassis allows the vehicle to switch between extended configuration for maximum cargo capacity and retracted configuration for enhanced maneuverability. This dynamic adjustment capability enables the vehicle to optimize its performance based on whether cargo capacity or ease of navigation through traffic is the priority
3Ease of operation
If the vehicle is designed to be compact for bicycle lane navigation, then the ease of operation is improved, but the cargo capacity is reduced
Solution Approach 1:
The vehicle features a motorized chassis that can be retracted to a compact configuration for navigating bicycle lanes and tight urban spaces, then extended when cargo capacity is needed. This dynamic transformation allows the vehicle to have both compact dimensions for ease of operation and expanded capacity for cargo transport
4Device complexity
If the electrical wiring runs through the rear chassis to power the chassis motor, then the device complexity is reduced, but the structural integrity of the chassis may be compromised
Solution Approach 1:
The electrical wiring is routed through channels or conduits integrated into the rear chassis structure, allowing the wiring to pass through the chassis without compromising its structural integrity. This approach maintains the chassis strength while providing a simplified wiring configuration compared to external routing
Data Source
AI summary
The present disclosure relates to an electric vehicle having one or more rear wheels and one or more front wheels, a motor for rotating the one or more rear wheels, an energy source powering the motor, a pedal in combination with the motor for assisting in rotating the one or more rear wheels, a rear chassis configured to carry a plurality of cargo boxes, and a chassis motor coupled to the rear chassis for extending and retracting the rear chassis, wherein electrical wiring runs from the energy source and through the rear chassis to power the chassis motor. The rear chassis may be set up in multiple configurations for the electric vehicle to transport cargo boxes and containers.
