Variable Length Vehicle Telescopic Rear Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Two-wheeled vehicles with additional cargo space often compromise maneuverability due to increased length or wheel span, affecting cornering and overall handling.
Innovation Solution
A vehicle with adjustable overall length, featuring extendable supports between a front and rear module, where the front wheel is locked to prevent movement while the rear module is driven relative to the front, allowing for extension or retraction of the vehicle's length to accommodate cargo needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the vehicle is built with additional built-in cargo space (elongated structure), then cargo carrying capacity is improved, but maneuverability deteriorates
Solution Approach 1:
The vehicle employs a telescopic mechanism that allows the distance between front and rear modules to be dynamically adjusted. The rear module can be extended backward to create cargo space when needed, and retracted forward to minimize vehicle length for maneuvering. This dynamic structural change enables the vehicle to switch between cargo-carrying mode and maneuvering mode, resolving the contradiction between cargo capacity and ease of operation.
2Quantity of substance
If the vehicle length is increased to provide cargo space, then cargo carrying capacity is improved, but cornering performance deteriorates
Solution Approach 1:
The telescopic mechanism enables the vehicle to dynamically adjust its length. During cornering maneuvers, the rear module can be retracted forward to minimize the wheel span and vehicle length, improving cornering performance. When cargo needs to be transported, the rear module extends backward to provide cargo space. This dynamic adjustment resolves the contradiction between cargo capacity and cornering performance.
3Ease of operation
If the vehicle is made shorter to improve maneuverability, then ease of operation is improved, but cargo carrying capacity deteriorates
Solution Approach 1:
The vehicle maintains a compact base configuration for improved maneuverability, but incorporates a telescopic mechanism that allows the rear module to extend backward when cargo space is required. This dynamic extension provides cargo carrying capacity only when needed, while maintaining short vehicle length for ease of operation during normal travel and maneuvering.
4Strength
If the vehicle structure is made rigid to provide structural integrity, then strength is improved, but adaptability deteriorates
Solution Approach 1:
The vehicle is divided into separate front and rear modules that can move relative to each other through a telescopic mechanism. This segmentation allows the vehicle to maintain rigid structural integrity within each module while enabling overall length adjustment between modules. The modular design provides both strength (through rigid modules) and adaptability (through relative movement capability).

AI summary
A vehicle including a front module including a front wheel and a rear module selectively moveably connected to the front module, the rear module including a rear wheel. The vehicle further includes an electric motor assembly, a mode selector, at least one extension assembly connected between the front module and the rear module for selectively extending and retracting to provide a selective variation in an overall length of the vehicle; and a vehicle control unit being communicatively connected between the mode selector and the electric motor assembly. The vehicle control unit performs a method for selectively changing the overall vehicle length. The method includes receiving from the mode selector an indication to change the overall length, determining that the front wheel is rotationally locked, and causing an electric motor to drive the rear wheel such that the rear module translates relative to the front module.
