Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If hearing care professionals rely on guesswork for initial fitting, then the fitting process is simple and quick, but the fitting accuracy and user comfort deteriorate
Solution Approach 1:
The system performs preliminary actions by collecting user profile information, fitting history, and device data before the fitting session. This advance preparation enables the algorithm to generate accurate initial sound processing parameters without requiring complex real-time adjustments during the fitting session, thereby improving fitting accuracy while maintaining process simplicity.
Solution Approach 2:
The patent introduces an intermediary algorithm that acts as a mediator between the user's historical data and the sound processing parameters. This algorithm automatically processes fitting history, user preferences, and device characteristics to generate optimized initial settings, eliminating the need for professionals to rely on guesswork while avoiding manual complexity.
2Ease of operation
If user experience values are not considered in initial fitting, then the fitting session is shorter and simpler, but user comfort and satisfaction worsen
Solution Approach 1:
The system enables self-service by allowing the algorithm to automatically determine user experience values and adjust sound processing parameters based on fitting history and user profiles. This automated self-adjustment improves user comfort through personalized settings while keeping the fitting session brief, as the system performs the complex analysis without requiring extended professional intervention.
Solution Approach 2:
The patent implements feedback mechanisms by utilizing fitting history data to inform initial parameter selection. The system feeds historical fitting outcomes, user preferences, and comfort levels back into the algorithm, which then optimizes initial settings accordingly. This feedback loop enhances user comfort while maintaining efficient fitting sessions.
3Productivity
If hearing care professionals adjust parameters manually during fitting sessions, then flexibility and adaptability are improved, but time consumption and complexity increase
Solution Approach 1:
The patent replaces the manual mechanical adjustment process with an automated computational system. Instead of professionals manually tweaking parameters based on experience, the system uses algorithms to automatically calculate and apply optimized sound processing parameters. This substitution dramatically improves fitting efficiency while the underlying complexity is managed by the automated system rather than requiring complex manual procedures.
Solution Approach 2:
The system efficiently manages complexity by systematically changing parameters based on user profiles and fitting history. The algorithm automatically adjusts multiple sound processing parameters simultaneously according to predetermined relationships and user-specific factors, improving productivity while keeping the parameter adjustment process organized and manageable rather than chaotic or overly complex.
