Solution Overview

Problem

Current smartphones face challenges in providing a user-friendly method to manage the mute function during active voice or video calls, especially when the screen is turned off, as users cannot easily determine if the mute function is activated and must navigate through unlocking and accessing the interface to un-mute, which is time-consuming and frustrating.

Innovation Solution

A system and method that provides a persistent visual indication of the mute function's status using a status indicator, allowing users to toggle between mute and un-mute states through predefined gestures or voice commands without needing to activate the screen or unlock the interface, utilizing detection modules for facial and hand characteristics to control the mute function.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the touchscreen display shuts off to conserve battery life, then energy consumption is reduced, but the user cannot see the mute function status and must unlock the device to manage it

Engineering Contradiction:
Improvebattery lifeVSAvoidease of managing mute function
Core Design Contradiction:
Use of energy by moving objectVSEase of operation

Solution Approach 1:

The patent introduces a status indicator LED as an intermediary element that communicates the mute function status without requiring the display to be on. The LED serves as a mediator between the mute function state and the user, providing visual feedback through light emission while the device remains in low-power mode with the display off.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system provides self-service by automatically managing the display state based on interaction patterns. When the user interacts with the device (such as answering a call), the display turns on automatically. When interaction ceases, the display automatically shuts off to conserve battery, while the mute status continues to be indicated by the LED without requiring user intervention.

Inventive Principle:
Principle #25Self-service

2Reliability

If the user must unlock the device and navigate to the phone application display to un-mute, then security is maintained, but time is lost and user frustration increases

Engineering Contradiction:
Improvedevice securityVSAvoidtime to un-mute
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements immediate visual feedback through the status indicator LED that shows the mute function status without requiring device unlocking. The LED provides real-time information about whether the microphone is muted, allowing users to understand the device state instantly while maintaining security by not requiring the display or full interface to be accessed.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent extracts the essential status indication function from the main display interface and places it in the status indicator LED. This separation allows the mute status to be viewed and managed independently from the main display, enabling quick status checks and reducing the need to unlock the device just to see or change the mute state.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If the display remains on to show the user interface, then the user can easily manage communication functions, but energy consumption increases

Engineering Contradiction:
Improvevisibility of user interfaceVSAvoidenergy consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent segments the user interface information into two separate components: the main display (which can be turned off to save energy) and the status indicator LED (which provides essential feedback with minimal energy consumption). The LED is divided into segments that can independently indicate different states (muted vs. not muted), allowing critical information to be displayed without requiring the entire display to remain active.

Inventive Principle:
Principle #1Segmentation

AI summary

A system includes a first mobile device configured to initiate communication with at least one other mobile device. The first mobile device includes a status indicator configured to provide a persistent visual indication to a user of the status of a mute function of the first user device during the active communication. The first mobile device further includes a user interface configured to receive predefined user input and allow the user to toggle between mute and un-mute states based on the user input regardless of whether a display of the device is shut off and/or the user interface is locked.
