Solution Overview

Problem

Existing sound collection apparatuses primarily receive sound statically, resulting in suboptimal sound reception, especially when sound sources are not aligned with the microphones, leading to difficulties in sound identification.

Innovation Solution

A method and device utilizing at least three microphones to calculate the position of a sounding point in a three-dimensional space and adjust the physical position and orientation of the apparatus to align with an optimal sound receiving region, ensuring better sound reception by either containing or approaching the sound source within this region.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the apparatus receives sound statically in certain positions, then the device complexity is reduced, but the sound reception quality deteriorates

Engineering Contradiction:
Improvedevice complexityVSAvoidsound reception quality
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent applies the dynamics principle by enabling the apparatus to dynamically adjust its physical position and orientation based on the calculated sounding point location. Instead of remaining static, the apparatus actively moves and reorients itself to optimize sound reception, resolving the contradiction between simplicity and reception quality

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements feedback by using the sound data from multiple microphones to calculate the sounding point position, then using this information to adjust the apparatus position, and continuing to monitor sound quality for further adjustments. This closed-loop feedback system ensures optimal sound reception while maintaining manageable device complexity

Inventive Principle:
Principle #23Feedback

2Ease of operation

If the apparatus is statically located, then the ease of operation is improved, but the sound identification accuracy deteriorates

Engineering Contradiction:
Improveease of operationVSAvoidsound identification accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent applies preliminary action by calculating the sounding point position before adjusting the apparatus position. This pre-calculation step ensures that the apparatus moves to the correct location in advance, maintaining ease of operation while improving sound identification accuracy

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The apparatus performs self-service by automatically calculating its own optimal position and orientation based on sound data, then adjusting itself accordingly. This self-directed adjustment improves sound identification accuracy without requiring complex external control systems

Inventive Principle:
Principle #25Self-service
