Solution Overview

Problem

Flexible display devices face challenges in maintaining audio quality due to bending, which can occlude microphones and speakers, degrading sound recording or broadcasting performance.

Innovation Solution

A system dynamically monitors the bend profile of flexible devices and uses microfluidics mechanisms to reposition audio devices, ensuring they are no longer occluded and maintain a threshold level of audio quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the flexible device is bent or folded to improve portability and durability, then the device becomes more portable and durable, but the audio devices (microphones and speakers) become occluded, degrading sound quality

Engineering Contradiction:

ImproveportabilityVSAvoidaudio quality

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements dynamic adjustment of audio device positions based on the real-time bend profile of the flexible device. Sensors detect the bending state, and actuators automatically reposition audio devices to maintain optimal acoustic orientation, allowing the system to adapt dynamically between folded (portable) and unfolded (audio quality) states

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system uses sensors to continuously monitor the bend profile and provides feedback to the control system. This feedback loop enables real-time detection of occlusion conditions and triggers automatic repositioning actions to maintain audio quality while preserving the flexibility and portability benefits

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If the flexible device is bent to improve portability, then the device becomes more portable, but the position of audio devices changes, degrading sound recording or broadcasting performance

Engineering Contradiction:

ImproveportabilityVSAvoidsound recording or broadcasting performance

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system performs preliminary repositioning of audio devices before occlusion occurs by monitoring bend profiles in advance. When a bending pattern that would cause occlusion is detected, the actuators proactively adjust audio device positions to predetermined optimal locations, preventing performance degradation before it happens

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces actuators as intermediary mechanisms between the flexible device structure and the audio devices. These actuators serve as mediators that actively adjust the position and orientation of audio devices in response to bend profile changes, decoupling the structural flexibility from audio performance requirements

Inventive Principle:

Principle #24Intermediary (Mediator)
