Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple audio processing algorithms are executed in sequence and/or in parallel to provide sophisticated signal processing capabilities, then the hearing enhancement capability is improved, but the reliability of achieving desired signal processing goals deteriorates due to complex interplay between algorithms

Engineering Contradiction:
Improvesignal processing capabilityVSAvoidpredictability of signal processing goal
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where the processor continuously monitors the processed audio signal and compares it against the desired signal processing goal. Based on this comparison, the processor automatically adjusts parameters of one or more audio processing algorithms to ensure the desired goal is achieved. This closed-loop feedback system resolves the contradiction by providing continuous verification and adjustment, making the complex multi-algorithm system reliable and predictable.

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If audio processing algorithms are continuously optimized during runtime to meet changing user preferences and environmental conditions, then the adaptability is improved, but the computational complexity and processing time increase

Engineering Contradiction:
Improveruntime optimization capabilityVSAvoidprocessing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies partial action by selectively adjusting parameters of only those audio processing algorithms that are relevant to the current deviation from the desired signal processing goal, rather than re-optimizing all algorithms. The processor identifies specific algorithms needing adjustment based on the comparison between processed and desired signals, thereby reducing computational complexity while maintaining runtime adaptability.

Inventive Principle:
Principle #16Partial or excessive action

3Reliability

If the hearing device monitors and adjusts audio processing in real-time by comparing input and processed signals, then the reliability of achieving signal processing goals is improved, but the use of energy increases due to continuous processing

Engineering Contradiction:
Improvesignal processing goal achievementVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic action by continuously monitoring the processed audio signal and comparing it against the desired signal processing goal at regular intervals during runtime. This periodic comparison and selective adjustment of algorithm parameters ensures reliable achievement of signal processing goals while managing energy consumption through scheduled rather than constant full-system processing.

Inventive Principle:
Principle #19Periodic action
