Solution Overview

Problem

Drivers face safety risks due to the need to turn their eyes away from the road to operate side-view mirrors, which can lead to missed collisions and accidents, as existing systems require manual input to view lateral rear images through a smart room mirror.

Innovation Solution

A device and method using a smart room mirror equipped with a camera sensor and motion sensor to recognize 3D gestures, allowing drivers to view lateral rear images from side-view mirrors without looking away, by displaying corresponding image information through a display unit based on gesture recognition and central processing analysis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the driver operates the button switch or touch key switch on the room mirror to view lateral rear images, then the driver can check the left and right side conditions of the vehicle, but the driver must turn eyes away from the road, causing safety risks

Engineering Contradiction:

Improveoperation of side-view mirror displayVSAvoiddriving safety

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent replaces the mechanical button switch or touch key switch operation with a gesture recognition system using camera sensors and motion sensors. The driver's gestures are captured by sensors and processed to control the display of lateral rear images, eliminating the need for manual switching operations that require eye diversion from the road.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces gesture recognition technology as an intermediary between the driver and the room mirror display system. The camera sensor and motion sensor act as intermediaries to detect driver gestures and translate them into control signals for displaying lateral rear images, allowing indirect control without manual switch operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the driver keeps eyes forward during driving, then driving safety is improved, but the driver cannot operate additional equipment or check side-view mirrors

Engineering Contradiction:

Improvedriving safetyVSAvoidaccess to vehicle equipment

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces manual mechanical operation of vehicle equipment with gesture-based control. The gesture recognition system allows the driver to operate the room mirror display and access vehicle equipment information through hand movements detected by camera and motion sensors, eliminating the need to divert eyes from the road.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system provides self-service by automatically detecting and interpreting driver gestures to control the display. The gesture recognition system autonomously translates driver intentions into system commands, allowing the driver to access equipment information without manual intervention or eye diversion.

Inventive Principle:

Principle #25Self-service

3Device complexity

If manual switch operation is used to view lateral rear images, then the system structure is simple, but the driver's attention is diverted from the road

Engineering Contradiction:

Improvecontrol system structureVSAvoiddriving safety

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent replaces simple mechanical switch operation with an electronic gesture recognition system. While this increases device complexity by adding camera sensors, motion sensors, and processing units, it eliminates the safety risk of eye diversion by allowing contactless, gesture-based control of the lateral rear image display.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
