Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commonly used discrete drivers for surround technologies in audio devices are often inaccurate due to individual variations in ear shape, as they cannot compensate for unique responses to simulated sound stages.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If discrete drivers are used for surround technologies, then the device complexity is reduced, but the audio accuracy deteriorates due to individual variations in ear shape
Solution Approach 1:
The patent implements movable drivers that can be adjusted to different positions along arcs, allowing the audio device to adapt dynamically to individual user ear shapes. This dynamic adjustment capability resolves the contradiction by enabling personalized audio accuracy without requiring multiple fixed driver configurations, thus maintaining device simplicity while improving measurement precision.
Solution Approach 2:
The patent changes the positional parameters of the drivers along predetermined arcs to optimize audio performance for different users. By adjusting driver positions rather than changing the entire driver configuration, the system achieves high audio accuracy while keeping the overall device complexity manageable through parameter optimization rather than structural redesign.
2Measurement precision
If movable drivers are added to allow position adjustment, then the audio accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent divides the driver adjustment mechanism into independent segments, where each driver can be adjusted separately along its own predetermined arc. This segmentation allows for precise audio calibration without requiring a complex overall mechanism, as each segment operates independently with its own simple adjustment path.
Solution Approach 2:
The patent constrains driver movement to predetermined arcs rather than allowing full three-dimensional movement. This dimensional constraint simplifies the mechanical structure by reducing the degrees of freedom, while still providing sufficient adjustment capability to achieve high audio accuracy for different user geometries.
3Measurement precision
If custom fitting is implemented for each user, then the audio accuracy is enhanced, but the ease of operation is reduced
Solution Approach 1:
The patent enables users to perform their own audio calibration by adjusting drivers along predetermined arcs based on their ear shapes. The self-service capability allows users to achieve personalized audio accuracy without requiring professional assistance, thereby maintaining ease of operation while enhancing measurement precision.
Solution Approach 2:
The patent pre-establishes adjustment paths and guidelines for driver positioning that users can follow during setup. By providing predetermined arcs and calibration procedures in advance, the system simplifies the user operation process while still enabling custom fitting for high audio accuracy.
