Tricycle Tilting Mechanism for Cornering Agility

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Traditional tricycles lack agility in cornering and leaning, making them less maneuverable compared to two-wheeled vehicles, and electric motorcycles with increased battery weight become unwieldy.

Innovation Solution

A tricycle design featuring a vehicle tilting system with a track assembly and sliding base assembly, allowing only the front body to tilt while maintaining the rear body's stability during turns, utilizing an arcuate track and roller sets for smooth sliding and a tilt-positioning mechanism with electronic control for speed-dependent disc brake operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If the number of batteries is increased to extend the range of electric motorcycles, then the range is improved, but the vehicle weight increases and becomes difficult to maneuver

Engineering Contradiction:

ImproverangeVSAvoidvehicle weight

Core Design Contradiction:

Duration of action of moving objectVSWeight of moving object

Solution Approach 1:

The vehicle body is divided into front body and rear body sections, with the tilting mechanism allowing the front body to rotate independently. This segmentation enables the front portion to lean during turns while the rear body remains stable, improving maneuverability without requiring weight reduction

Inventive Principle:

Principle #1Segmentation

2Weight of moving object

If traditional tricycle structure is used to reduce weight, then the vehicle weight is reduced, but the vehicle lacks agility in cornering and leaning

Engineering Contradiction:

Improvevehicle weightVSAvoidcornering agility

Core Design Contradiction:

Weight of moving objectVSEase of operation

Solution Approach 1:

The patent introduces a dynamic tilting mechanism where the front body can rotate relative to the rear body through a track assembly and sliding base assembly. This dynamic capability allows the front body to lean into turns, providing cornering agility similar to two-wheeled vehicles while maintaining the lighter weight advantage of three-wheeled vehicles

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If the front body is allowed to tilt during turns, then cornering agility is improved, but the rear body stability may be compromised

Engineering Contradiction:

Improvecornering agilityVSAvoidrear body stability

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The vehicle is segmented into front body and rear body with independent motion capabilities. The front body can tilt independently while the rear body remains stable through the constraint mechanism, resolving the contradiction between cornering agility and rear body stability

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The track assembly and sliding base assembly act as intermediary mechanisms between the front and rear bodies. These components enable the front body to tilt while constraining the rear body to remain stable, mediating the conflicting requirements of agility and stability

Inventive Principle:

Principle #24Intermediary (Mediator)
