Solution Overview

Problem

Existing vehicle rearview mirrors primarily reflect monotonous road conditions and lack flexibility in image display, failing to provide a comprehensive view of the vehicle's surroundings.

Innovation Solution

An image display method and system for vehicle rearview mirrors that captures and displays multiple images, including vehicle environment images and multimedia content, in a split-screen manner on the rearview mirrors, using external and internal image obtaining modules, and allows users to select target images for full-screen display via a touch module.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional single-image reflection is used in rearview mirrors, then the mirror structure remains simple, but the image display flexibility and information richness are limited

Engineering Contradiction:
Improveimage display flexibilityVSAvoidmirror system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The rearview mirror display surface is segmented into multiple independent display regions, each capable of showing different images (rear camera view, front camera view, navigation, media). This segmentation allows the mirror to display multiple types of information simultaneously while maintaining a unified mirror structure, resolving the contradiction between display flexibility and system complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The rearview mirror is transformed into a multi-functional device that can display various types of content (surrounding environment, navigation, media playback) on a single display surface. This universal display capability eliminates the need for separate displays for different functions, improving adaptability while controlling overall system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Loss of information

If multiple images are displayed simultaneously on the rearview mirror, then the information richness and comprehensive view are improved, but the image processing and display control complexity increases

Engineering Contradiction:
Improvesurrounding environment informationVSAvoidimage processing complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The display surface is divided into multiple independent regions, with each region dedicated to displaying specific information (e.g., rear view, front view, navigation). This spatial segmentation allows simultaneous display of multiple information types without requiring complex dynamic switching or processing, reducing the overall image processing complexity while maximizing information richness.

Inventive Principle:
Principle #1Segmentation

3Area of moving object

If only flat mirrors are used for inner rearview mirrors, then the manufacturing is simple, but the field of vision enlargement capability is limited

Engineering Contradiction:
Improvedriver's field of visionVSAvoidmirror manufacturing simplicity
Core Design Contradiction:
Area of moving objectVSEase of manufacture

Solution Approach 1:

The patent employs convex mirrors for external rearview mirrors to expand the driver's field of vision. The curved surface of the convex mirror captures a wider angular range of the rear environment, projecting it onto the display surface. This curvature-based solution achieves field of vision enlargement while maintaining relatively simple manufacturing processes.

Inventive Principle:
Principle #14Spheroidality (Curvature)
