Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current people-carrying vehicles are not easily foldable, making them inconvenient for storage and transportation, and existing separable designs require significant time and labor to disassemble.
Innovation Solution
A foldable people-carrying vehicle with a chassis, pivoted seat, footrest, rear wheel assembly, front wheel assembly, and a telescopic steering device that can be lowered for a compact configuration, along with an auxiliary wheel assembly for easy movement in a folded state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle structure is made rigid and stable for reliable operation, then operational reliability is improved, but the vehicle cannot be folded for compact storage and transportation
Solution Approach 1:
The vehicle is divided into multiple separable components including the seat assembly, footrest assembly, steering device, and wheel assemblies. Each component can be independently folded or detached, transforming the rigid structure into a compact folded configuration while maintaining structural integrity during operation
Solution Approach 2:
The vehicle employs dynamic structural elements including pivoted connections between seat and chassis, telescopic steering columns, and collapsible wheel assemblies. These dynamic elements allow the vehicle to transition between an expanded operational state with reliable stability and a compact folded state for storage
2Ease of operation
If the vehicle is designed as a separable structure for easy folding, then storage convenience is improved, but significant time and labor are required to separate the vehicle
Solution Approach 1:
The vehicle incorporates pre-configured folding mechanisms and quick-release connections that have been prepared in advance during manufacturing. Users simply need to activate the folding action or release latches, and the pre-engineered joints and pivots automatically guide the components into their folded positions, eliminating complex manual disassembly procedures
Solution Approach 2:
The vehicle is divided into multiple separable components including the seat assembly, footrest assembly, steering device, and wheel assemblies. Each component can be independently folded or detached, transforming the rigid structure into a compact folded configuration while maintaining structural integrity during operation
3Ease of operation
If the steering device is kept in a raised position for operational use, then steering functionality is maintained, but the overall vehicle height increases reducing compactness
Solution Approach 1:
The steering device incorporates a telescopic column that can dynamically adjust its length and position. During operation, the column extends to provide proper steering height and functionality. When folding, the column retracts or pivots to reduce overall vehicle height, enabling compact storage without compromising operational capabilities

AI summary
A vehicle includes a chassis body, a footrest member pivoted to a front end of the chassis body, a rear wheel assembly joined on the chassis body, a seat, a front wheel assembly in front of the footrest member, and a steering device; the seat is pivoted on an upper end of a supporting mechanism, which is pivoted on the chassis body, and can be moved between a raised in-use position and a lowered not-in-use one; the steering device includes a telescopic part, and is pivoted on a pivotal component protruding from an axle of the front wheel assembly to be movable between a raised in-use position and a lowered not-in-use one; an auxiliary wheel assembly is arranged in front of the footrest member and above the front wheel assembly so that the vehicle can be moved on the auxiliary wheel assembly when it is in a folded configuration.
