Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional static hearing-based methods are used to control audio signal output, then the fitting procedure can be completed, but the system fails to account for dynamic changes in hearing ability over time and environment
Solution Approach 1:
The patent transforms the static hearing threshold measurement into a dynamic system by continuously or periodically remeasuring hearing thresholds and adjusting audio signal output levels in real-time. The hearing aid device dynamically adapts to changing hearing conditions by updating the output level determination based on current hearing threshold measurements rather than relying on fixed historical data
Solution Approach 2:
The system performs self-adjustment by automatically remeasuring hearing thresholds and recalibrating output levels without requiring external intervention. The device monitors its own performance and autonomously adjusts parameters based on detected changes in hearing ability, enabling self-optimization of the audio output
2Productivity
If hearing tests and fitting are performed separately as in conventional methods, then the procedure follows standard protocol, but the system cannot capture real-time hearing improvements
Solution Approach 1:
The patent implements continuous hearing threshold measurement and output level adjustment, replacing the discrete, periodic nature of conventional fitting procedures. The system continuously monitors hearing ability and maintains optimal audio output levels through ongoing adaptation, eliminating gaps between fitting sessions where hearing changes go undetected
Solution Approach 2:
The system establishes a closed-loop feedback mechanism where hearing threshold measurements continuously inform output level adjustments. The device measures hearing thresholds, determines appropriate output levels based on these measurements, applies the adjustments, and then remeasures to verify effectiveness, creating a self-correcting cycle that responds to hearing changes in real-time
3Ease of operation
If audio signal output is adjusted based on static hearing thresholds, then the initial fitting can be achieved, but subsequent hearing improvements are not utilized
Solution Approach 1:
The system automatically performs the complex task of hearing threshold measurement and output level optimization without requiring user intervention. The device self-adjusts audio parameters based on its own measurements of hearing ability, eliminating the need for users to manually adjust settings while maintaining optimal performance
Solution Approach 2:
The patent implements automatic feedback-driven adjustment where the system measures hearing thresholds, processes this information to determine optimal output levels, and applies adjustments autonomously. This closed-loop system continuously monitors and responds to hearing changes without requiring user awareness or action
