Communication Shield Assembly for Audio Secrecy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shield devices fail to effectively maintain the secrecy of audio information transmitted through mouthpieces during communication, especially in environments like sporting events where tactical instructions need to be kept confidential.
Innovation Solution
A shield device integrated with an audio headset, featuring a microphone with a pivotable arm and a shield that covers the mouthpiece, providing lateral and vertical adjustability to ensure complete coverage of the mouth, thereby preventing eavesdropping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a shield device is added to cover the mouthpiece, then the secrecy of audio information is improved, but the device complexity increases
Solution Approach 1:
The shield device is merged with the existing headset structure by coupling it to the microphone assembly. The shield shares the same mounting mechanism and spatial arrangement as the microphone, integrating security functionality into the communication device without requiring a completely separate system.
Solution Approach 2:
The shield incorporates a pivotable arm member that allows dynamic adjustment of the shield's position and orientation. This enables the shield to adapt to different user positions and communication scenarios while maintaining effective coverage, rather than being a fixed static structure.
2Loss of information
If the shield is made to fully cover the mouth, then the secrecy of audio information is improved, but the ease of operation deteriorates due to reduced mouthpiece adjustability
Solution Approach 1:
Both the shield and mouthpiece are made dynamically adjustable through pivotable arm members. The shield can pivot to maintain coverage while the mouthpiece can independently adjust for comfort and positioning, allowing both functions to operate optimally simultaneously rather than being locked in fixed positions.
Solution Approach 2:
The adjustable mechanism is segmented into independent components - the shield assembly with its own pivotable arm and the mouthpiece with its separate positioning capabilities. This allows each component to be adjusted independently without interfering with the other, maintaining both coverage and usability.
3Loss of information
If the shield structure is made more complex to ensure complete coverage, then the secrecy of audio information is improved, but the manufacturing complexity increases
Solution Approach 1:
The pivotable arm member serves multiple functions: it positions the shield for coverage, allows adjustment for different users, and enables the shield to adapt to various communication angles. This single component achieves what would otherwise require multiple separate structural elements, simplifying manufacturing while ensuring complete coverage.
Solution Approach 2:
The shield's effectiveness is achieved through adjustable parameters (position, orientation, angle) rather than through complex fixed geometry. By allowing the shield to be positioned at different angles and locations through the pivotable mechanism, complete coverage is achieved without requiring a complex multi-component structure.

AI summary
A communication shield assembly covers a mouth of a wearer when the wearer speaks into a mouthpiece. The assembly includes an audio headset including a head strap and a speaker. The speaker is coupled to the head strap. A microphone has an arm member and a mouthpiece. A first end of the arm member is coupled to the audio headset and a second end of the arm member is coupled to the mouthpiece. The mouthpiece extends in front of a mouth of a user for transmitting audio information to an external receiver when the user speaks into the mouthpiece. A shield is coupled to the microphone and is positioned adjacent to the mouthpiece wherein the shield covers the mouth of the user when the user speaks into the mouthpiece.
