Micromobility Rear Triangle Configuration for Concealed Component Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Legacy micromobility vehicle designs expose components such as batteries, cables, and locks, making them susceptible to theft and vandalism, and lack efficient use of rear triangle space.
Innovation Solution
A rear triangle configuration featuring a wishbone seat stay, rotatable lock cable, and complementary dropout structures to conceal and secure components, including a channel for motor cables and a battery compartment within the downtube.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If components are exposed on legacy micromobility vehicles, then accessibility and ease of operation are improved, but security and vulnerability to theft/vandalism worsen
Solution Approach 1:
The patent extracts vulnerable components (battery, control unit, lock mechanism) from exposed positions and relocates them into concealed compartments within the rear triangle structure, removing them from harm's way while maintaining functional accessibility when needed
Solution Approach 2:
The patent nests multiple components within the rear triangle structure, placing the battery, control unit, and lock mechanism inside concealed compartments that are integrated into the existing frame geometry, thereby hiding components while utilizing available space efficiently
2Device complexity
If rear triangle space is left unused in legacy designs, then structural simplicity is maintained, but space utilization and component concealment worsen
Solution Approach 1:
The patent makes the rear triangle structure multi-functional by using it both for its primary structural support role and as a concealment housing for multiple components, thereby eliminating wasted space without adding separate dedicated housings
Solution Approach 2:
The patent merges the function of component housings with the rear triangle frame structure itself, combining what were previously separate elements (frame and component enclosures) into a single integrated structure that provides both structural support and component concealment

AI summary
Techniques are disclosed for a rear triangle configuration for a micromobility transit vehicle. In accordance with one or more embodiments, a micromobility transit vehicle is provided. The micromobility transit vehicle may include a seat tube, a wishbone seat stay including a fork and post connecting the fork to the seat tube, a collar connected to the post and rotatable about an axis defined by the post, and a lock cable connected to the collar to rotate about the post. The fork may be connected to a pair of chain stays, such as via a pair of rear dropouts, to extend around a portion of a rear wheel. The rear dropouts may include a vertical dropout structure and positively lock to an electric motor, such as via complementary structures. A channel may be disposed in a rear dropout to receive a motor cable running to the electric motor.
