Solution Overview

Problem

Existing media device docking stations interfere with sound reception and transmission, causing muffling and feedback between the speaker and microphone, which reduces sound quality.

Innovation Solution

The docking station incorporates acoustic interfaces, including gaps and channels, to allow unobstructed sound flow between the media device and the environment, with internal and external apertures that facilitate sound transmission and reception, reducing pressure and echo.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the media device is docked to the docking station, then the media device is securely positioned and charged, but the docking station structure interferes with and muffles sound transmission

Engineering Contradiction:
Improvesecure positioningVSAvoidsound muffling
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The docking station structure is segmented into separate functional zones: a docking interface for secure positioning and charging, and separate acoustic passages for sound transmission. This segmentation allows the docking function to be fulfilled while preserving acoustic pathways that prevent sound muffling.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Acoustic passages and gaps act as intermediaries between the media device and the external environment. These passages mediate the sound transmission by providing dedicated pathways that bypass the docking station's structural barriers, enabling clear audio transmission while maintaining the docking connection.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the media device is docked to the docking station, then the media device is securely positioned, but feedback or echo is created between speaker and microphone

Engineering Contradiction:
Improvesecure positioningVSAvoidfeedback or echo
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The acoustic pathways are segmented into separate channels for sound output and input. The speaker and microphone are positioned in relation to each other through the acoustic passage structure, which segments the acoustic field to prevent direct feedback loops while maintaining secure docking.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The acoustic passages serve as intermediaries that control the acoustic field between the speaker and microphone. By providing structured pathways, these passages mediate the acoustic interaction to prevent feedback and echo while allowing the docking connection to remain secure.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If gaps and acoustic passages are added to the docking station, then sound transmission is improved, but the device complexity increases

Engineering Contradiction:
Improvesound interferenceVSAvoiddocking station structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The acoustic passages and gaps are merged with the docking station's structural components rather than being separate add-on elements. The acoustic functionality is integrated into the existing docking structure, combining structural support and acoustic transmission functions to minimize additional complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The docking station structure is designed to serve multiple functions: providing secure mechanical docking, enabling electrical charging connections, and facilitating acoustic transmission. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity.

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