Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing leaning vehicles face challenges in providing a function switch for canceling accident notifications when overturned, as conventional switches are often obscured or require larger vehicle designs, making it difficult for riders to operate them in various overturned positions.

Innovation Solution

The leaning vehicle is equipped with a first cancel switch positioned in a center region visible in multiple horizontal directions during an overturned state, allowing easy operation by the rider, and optionally includes a second cancel switch with a cover or different visibility characteristics to enhance recognition.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the cancel switch is provided in the right switch box, then it is easily accessible during normal operation, but it becomes obscured and difficult to operate when the vehicle overturns to the right

Engineering Contradiction:

Improveaccessibility of cancel switchVSAvoidvisibility of cancel switch during overturn

Core Design Contradiction:

Ease of operationVSDifficulty of detecting and measuring

Solution Approach 1:

The cancel switch function is segmented into two separate switches: a first cancel switch in the right switch box and a second cancel switch in the left switch box. This segmentation ensures that regardless of which side the vehicle overturns to, at least one cancel switch remains visible and accessible to the rider.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different switch boxes are assigned different functions based on their location. The right switch box contains the first cancel switch for right-side overturn scenarios, while the left switch box contains the second cancel switch for left-side overturn scenarios. Each switch box is optimized for its specific operational context.

Inventive Principle:

Principle #3Local quality

2Difficulty of detecting and measuring

If the cancel switch is provided in the left switch box, then it becomes visible when overturned to the left, but it is difficult to see when overturned to the right

Engineering Contradiction:

Improvevisibility of cancel switch during overturnVSAvoidaccessibility of cancel switch

Core Design Contradiction:

Difficulty of detecting and measuringVSEase of operation

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The switch configuration is asymmetrically designed with different switch boxes serving different purposes. The right switch box is optimized for right-side operations and visibility, while the left switch box is optimized for left-side operations and visibility, creating an asymmetric but functionally balanced system.

Inventive Principle:

Principle #4Asymmetry

3Difficulty of detecting and measuring

If cancel switches are provided in both left and right switch boxes, then visibility and accessibility are improved during overturn, but the vehicle size increases

Engineering Contradiction:

Improvevisibility of cancel switch during overturnVSAvoidvehicle size

Core Design Contradiction:

Difficulty of detecting and measuringVSVolume of moving object

Solution Approach 1:

The switch boxes are designed to serve multiple functions. In addition to containing cancel switches, the switch boxes also house other vehicle control switches and operational components. This multi-functionality allows the system to provide comprehensive cancel switch coverage without significantly increasing overall vehicle size.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

This invention provides a novel function switch in a leaning vehicle. The leaning vehicle includes a first cancel switch for cancelling notification of overturn occurrence information to outside of the leaning vehicle by a leaning-vehicle-overturn-notification-system. A handle includes one or more right switch boxes that are disposed to the left of a right handle grip, and one or more left switch boxes that are disposed to the right of a left handle grip. The first cancel switch is disposed at a position that, in the leaning vehicle in an upright state, is within a center region located between a plane perpendicular to the left-right direction that includes the left end of a right switch box which is disposed furthest to the left among the one or more right switch boxes, and a plane perpendicular to the left-right direction that includes the right end of a left switch box which is disposed furthest to the right among the one or more left switch boxes. The first cancel switch is disposed at a position that is visible in one or more horizontal directions in the leaning vehicle in an overturned state.
