Segmented Siderails for One-Wheeled Vehicle Stability and Clearance

Solution Overview

Problem

Existing one-wheeled electric vehicles lack effective siderails that provide improved stability, rear end clearance, and foot support, especially during downhill operations.

Innovation Solution

The implementation of siderails with a structural rail design featuring a rearmost section extending rearward at an upward angle, a frontmost section extending forward at an upward angle, and additional segments arranged at specific angles to enhance stability and clearance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If traditional straight siderails are used, then the structure is simple, but the vehicle lacks stability and rear end clearance during downhill operations

Engineering Contradiction:

Improvevehicle stabilityVSAvoidsiderail structure complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The siderail is divided into multiple segments (first segment, second segment, third segment) with different orientations. The first segment extends forward at an upward angle, the second segment extends backward at an upward angle, and the third segment connects them. This segmentation allows each segment to serve a specific function: the first segment provides front stability, the second segment provides rear clearance and downhill stability, and the third segment connects them while maintaining structural integrity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The siderail transitions from a traditional single-plane straight structure to a three-dimensional multi-segment structure with varying orientations. The segments are arranged at different angles relative to the vehicle's longitudinal axis, creating a spatial configuration that provides both longitudinal stability and lateral clearance. This dimensional transformation enables the siderail to address multiple functional requirements simultaneously.

2Ease of operation

If the siderail is designed with multiple segments at specific angles, then rear end clearance and maneuverability are improved, but the manufacturing complexity increases

Engineering Contradiction:

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

The siderail is divided into multiple segments (first segment, second segment, third segment) with different orientations. The first segment extends forward at an upward angle, the second segment extends backward at an upward angle, and the third segment connects them. This segmentation allows each segment to serve a specific function: the first segment provides front stability, the second segment provides rear clearance and downhill stability, and the third segment connects them while maintaining structural integrity.

Inventive Principle:

3Length of stationary object

If the rear section of the siderail extends at an upward angle, then rear end clearance is improved for downhill operations, but the overall structural integrity may be compromised

Engineering Contradiction:

Improverear end clearanceVSAvoidsiderail structural integrity

Core Design Contradiction:

Length of stationary objectVSStrength

Solution Approach 1:

The siderail is divided into multiple segments (first segment, second segment, third segment) with different orientations. The first segment extends forward at an upward angle, the second segment extends backward at an upward angle, and the third segment connects them. This segmentation allows each segment to serve a specific function: the first segment provides front stability, the second segment provides rear clearance and downhill stability, and the third segment connects them while maintaining structural integrity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different segments of the siderail have different local properties optimized for their specific functions. The second segment, which provides rear clearance, is designed with specific geometric properties that balance clearance provision with structural strength. The connection segments are designed to transfer loads effectively between the upward-angled portions and the vehicle frame, ensuring overall structural integrity while maintaining the clearance benefit.

AI summary

A siderail for a one-wheeled vehicle may include an elongate structural rail having a web extending from a first longitudinal end to a second longitudinal end. The rail is defined by four segments: a central segment defining a horizontal reference, a rear segment extending directly away from the central segment at an upward angle, a first forward segment extending directly away from the central segment at a downward angle, and a second forward segment extending directly away from the first forward segment at an upward angle.
