Solution Overview

Problem

Users cannot determine whether a user function is being operated based on a security function or not in electronic devices, leading to uncertainty about the safety of application operations.

Innovation Solution

A method and electronic device that receive a request for activating a security function, confirm the presence of a security indicator, and apply it to a security function screen image, allowing users to recognize the application of the security function.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a security function is implemented in an electronic device, then the security level is improved, but the user cannot determine whether the security function is being operated

Engineering Contradiction:

Improvesecurity levelVSAvoiduser awareness of security function operation

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent applies a security indicator (such as an icon or visual marker) that changes color or appears/disappears to indicate the operational state of the security function. This visual feedback mechanism allows users to immediately recognize whether security processing is active without adding complexity to the security function itself.

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The patent introduces a security indicator as an intermediary element between the security function and the user. This indicator serves as a visual mediator that communicates the security function's operational status to the user, resolving the information asymmetry without interfering with the security function's core operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of information

If a security indicator is added to indicate security function operation, then user awareness is improved, but the device complexity increases

Engineering Contradiction:

Improveuser awareness of security function operationVSAvoidsystem complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The patent uses a visual copy or representation (the security indicator) that mirrors the operational state of the security function. Instead of modifying the security function itself, a simplified visual copy is created and displayed to the user, providing information about security operation without adding functional complexity.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent separates the security function from its indication mechanism. The security function operates independently in the background, while the security indicator is a separate visual layer that communicates status. This segmentation allows the security function to remain simple while providing comprehensive user feedback.

Inventive Principle:

Principle #1Segmentation

AI summary

A method and an electronic device are provided for operating a security function. The method includes receiving a request for activation of a security function, confirming whether a security indicator is set, and when the security indicator is set, applying the security indicator to a security function screen image, based on activation of the security function, and outputting the security function screen image to a display of the electronic device.
