Solution Overview

Problem

Portable communications devices often mute audio outputs in inconspicuous locations, making it difficult for users to receive important audio messages, especially in situations where they need to remain silent but still want to be informed of incoming communications.

Innovation Solution

A portable communications device with a movable panel that switches between positions to mute or unmute the audio output interface, converting audio messages to visual messages when muted, allowing them to be displayed on a panel display, and storing these messages for later retrieval.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the audio output interface is muted using conventional switches, then the user can remain silent during meetings, but the user becomes unaware that the audio output is muted and cannot receive audio messages

Engineering Contradiction:
Improveaudibility of device during meetingsVSAvoiduser awareness of mute status
Core Design Contradiction:
Object-affected harmful factorsVSLoss of information

Solution Approach 1:

The patent uses visual display elements that change color or illumination state to indicate mute status. The display shows different visual cues (such as colored indicators or text messages) to inform users when the audio output is muted, resolving the contradiction between maintaining silence and providing awareness of the mute state.

Inventive Principle:
Principle #32Color changes

2Object-affected harmful factors

If the audio output interface is muted, then the user can maintain confidentiality during operations, but the user cannot receive or access audio messages

Engineering Contradiction:
Improveconfidentiality during operationsVSAvoidaccess to audio messages
Core Design Contradiction:
Object-affected harmful factorsVSLoss of information

Solution Approach 1:

The patent introduces a visual display as an intermediary that conveys message information when audio output is muted. The display shows visual representations of received messages (such as text or icons), allowing users to access message content without audio output, thus maintaining confidentiality while preserving information access.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the output parameter from audio to visual when mute mode is activated. Instead of outputting audio messages through the speaker, the system converts or presents message information in visual form on the display, allowing users to receive and access messages while the audio output remains muted.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If conventional mute switches are placed on the device, then the mute function is accessible, but the switches are located in inconspicuous locations making it difficult for users to locate and control the mute function

Engineering Contradiction:
Improvemute control accessibilityVSAvoidswitch location visibility
Core Design Contradiction:
Ease of operationVSDifficulty of detecting and measuring

Solution Approach 1:

The patent integrates the mute control function into the existing display interface, which serves multiple purposes (showing status, providing control, and giving feedback). Users can control mute status through the display, eliminating the need for separate physical switches and making the control function universally accessible through the main interface.

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

Solution Approach 2:

The display serves as an intermediary that provides both information about mute status and control capabilities. Instead of requiring users to locate and manipulate inconspicuous physical switches, the display presents clear visual indicators and accepts user input through familiar touchscreen or button interfaces, making mute control highly visible and accessible.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A portable communications device (100) having a panel (110) movable between a first position and a second position, a receiver to receive incoming audio messages, a memory (420) and an electronic processor (410). The electronic processor (410) determines whether the panel (110) is in a first position or a second position. The electronic processor (410) converts an audio portion of the incoming audio message to a visual message and displays the visual message on a display (145) of the portable communications device (100).
