Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users face safety hazards while walking and using mobile terminals for instant messaging, as the device's screen blocks their view of the road, leading to inconvenience and potential safety risks.

Innovation Solution

A method and apparatus that enable switching the background of an instant messaging window on a mobile terminal to a real-time image captured by the device's camera, allowing users to view their surroundings without interrupting message viewing or sending.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the user views or replies to a message on the mobile terminal screen, then the instant messaging function is improved, but the user's view of the road condition is blocked causing safety hazards

Engineering Contradiction:

Improveinstant messaging convenienceVSAvoidroad safety hazard

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent switches the camera from capturing images in the traditional front-facing dimension to capturing images from the rear dimension (behind the device). This allows the rear camera to capture road conditions that are blocked by the device when held in front of the user during messaging activities

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent introduces a rear camera as an intermediary device to capture road condition images. This intermediary captures the blocked view and presents it to the user through the screen, allowing the user to see road conditions without moving the device away from their viewing position

Inventive Principle:

Principle #24Intermediary (Mediator)

2Stability of the object's composition

If the mobile terminal blocks the road condition view, then the device can be held in position for messaging, but the user safety is compromised

Engineering Contradiction:

Improvedevice positioning stabilityVSAvoiduser safety

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The rear camera acts as an intermediary that captures the road view without requiring the device to be moved from its stable positioning in front of the user. The captured image is then displayed on the screen, providing visual information about road conditions while maintaining device stability

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent displays the rear camera captured image on the screen with appropriate visual presentation, allowing the user to perceive road conditions through the display without changing the physical position or orientation of the device

Inventive Principle:

Principle #32Color changes
