Solution Overview

Problem

Existing leaning vehicles face challenges in displaying various vehicle information due to limited space, particularly on the rear-view mirror, which restricts the enlargement of the display area.

Innovation Solution

The implementation of two display portions located in regions of space (i) or (ii) that are not visible from the front position but visible from the rear, allowing for the simultaneous display of different vehicle information visualizations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If vehicle information is displayed on the rear-view mirror, then the rider can see vehicle information, but the rear-view mirror size cannot be enlarged

Engineering Contradiction:
Improvevehicle information displayVSAvoidrear-view mirror area
Core Design Contradiction:
Loss of informationVSArea of stationary object

Solution Approach 1:

The display function is segmented from the rear-view mirror structure. The mirror body remains unchanged in size, while a separate display portion is added that can show vehicle information without requiring the mirror itself to be enlarged.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The display portion is positioned in a spatial region that is visible from the rear position but not from the front position. This utilizes a different spatial dimension for information display, allowing the mirror size to remain small while still providing comprehensive information display capability.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Loss of information

If various vehicle information is displayed, then the information completeness increases, but the display area requirement increases

Engineering Contradiction:
Improvevehicle information completenessVSAvoiddisplay area
Core Design Contradiction:
Loss of informationVSArea of stationary object

Solution Approach 1:

By positioning the display portion in a region visible from the rear but not from the front, the patent creates an additional display dimension that does not compete with the front-view mirror area, thereby enabling comprehensive information display without proportionally increasing the overall display area.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Loss of information

If display is added on the top face of the rear-view mirror, then vehicle information can be displayed, but the recognizability of vehicle state from front position deteriorates

Engineering Contradiction:
Improvevehicle information displayVSAvoidvehicle state recognizability from front
Core Design Contradiction:
Loss of informationVSDifficulty of detecting and measuring

Solution Approach 1:

The display portion is strategically positioned in a spatial region that is visible from the rear position but not from the front position. This dimensional separation ensures that information display does not interfere with the front-view recognizability of vehicle state, as the display is effectively in a different visual dimension for front observers.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

The present teaching provides a leaning vehicle that is capable of displaying various vehicle information. A leaning vehicle according to the present teaching includes: a seat; a meter; a left rear-view mirror; a right rear-view mirror; and a first display portion and a second display portion that are both located in the leaning vehicle, in a region of space (i) or (ii) as defined below, in such a manner as not to be visible from an in-front position but as to be visible from a rearward position with respect to the forward-backward direction of the leaning vehicle, and are configured to display a first display visualization and a second display visualization, respectively, at the same time to deliver a piece of vehicle information in tandem. The region of space (i) is defined by the overlap among: a region that is more upward than an upper end of the meter with respect to the upward-downward direction of the leaning vehicle; a region that is either one section or two adjacent sections of four sections into which an area that is, with respect to the leftward-rightward direction of the leaning vehicle, more rightward than a left end of the left rear-view mirror and more leftward than a right end of the right rear-view mirror is divided equally in the leftward-rightward direction; and a region that is more frontward than a front end of the seat with respect to the forward-backward direction of the leaning vehicle. The region of space (ii) is defined by the overlap between: either a region that is, with respect to the leftward-rightward direction of the leaning vehicle, more rightward than the left end of the left rear-view mirror and more leftward than a left end of the meter, or a region that is, with respect to the leftward-rightward direction of the leaning vehicle, more leftward than the right end of the right rear-view mirror and more rightward than a right end of the meter; and the region that is more frontward than the front end of the seat with respect to the forward-backward direction of the leaning vehicle.
