Universal Micromobility Vehicle Ergonomics for Moderate Trips
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional micromobility transportation options are not well-suited for moderate distance trips (2-5 miles) in urban environments, leading to user fatigue and decreased selection of these options for such journeys due to discomfort and lack of suitable features for terrain navigation and cargo storage.
Innovation Solution
A universal micromobility electric vehicle with fixed dimensions and features, including a frame, footboard, seat, and handlebars, designed for a 'one-size-fits-all' approach to accommodate users of varying sizes, providing comfort, ease of use, and storage options, suitable for moderate distance trips across different terrains.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If conventional micromobility transportation options are used for moderate distance trips, then users can travel shorter distances, but users experience fatigue and discomfort on trips of 2-5 miles
Solution Approach 1:
The patent applies parameter changes by optimizing specific dimensional parameters of the vehicle - seat height (500-600mm from footboard), handlebar height (700-900mm from footboard), and footboard position (160-240mm from ground). These parameter adjustments create an ergonomic configuration that reduces user fatigue and discomfort during moderate distance trips of 2-5 miles, directly resolving the contradiction between extended trip duration and user comfort.
2Adaptability or versatility
If adjustable components are added to accommodate different user sizes, then versatility is improved, but device complexity and manufacturing costs increase
Solution Approach 1:
The patent implements universality by designing a fixed-configuration vehicle with standardized dimensions that serves all users within a population range. The seat is positioned at a fixed vertical distance of 500-600mm from the footboard, handlebars at 700-900mm from the footboard, and the footboard at 160-240mm from the ground. This universal design eliminates the need for adjustable components while accommodating diverse user sizes, thereby reducing device complexity and manufacturing costs while maintaining versatility.
3Ease of manufacture
If fixed dimensions are used for all components, then manufacturing and maintenance costs are reduced, but adaptability to different user sizes decreases
Solution Approach 1:
The patent resolves this contradiction by carefully selecting specific parameter ranges that work universally across different user sizes. The seat-to-footboard distance of 500-600mm, handlebar-to-footboard distance of 700-900mm, and footboard-to-ground distance of 160-240mm are optimized parameters that provide ergonomic comfort for a broad population without requiring adjustment mechanisms. These fixed parameters simplify manufacturing and maintenance while maintaining adequate adaptability.

AI summary
A micromobility vehicle for use in a vehicle share system includes a frame, a footboard fixed to the frame, a seat fixed to the frame, handlebars, and a computing device. The frame includes a horizontal portion and an angled portion. The seat is separated from the footboard in a vertical direction by a fixed distance. The handlebars are separated from the footboard in the vertical direction by a fixed distance. A cargo storage location is at least partially disposed between the seat and the footboard. The computing device is fixed to the frame and capable of executing a transportation matching system application.
