Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional professional fitting process is used, then fitting accuracy can be maintained, but fitting efficiency is extremely low and service cost is high
Solution Approach 1:
The patent enables users to perform hearing threshold tests and gain value adjustments independently through mobile devices and hearing earphones with built-in microphones. The system automatically calculates target compensation gain values and guides users through the fitting process, eliminating the need for professional audiologists to perform manual testing and adjustment, thus dramatically improving fitting efficiency while maintaining accuracy through automated algorithms
Solution Approach 2:
The patent replaces traditional mechanical/professional fitting systems with an automated electronic system. Mobile devices and hearing earphones with integrated microphones substitute for professional pure tone test equipment. The system uses automated sound delivery and recording through the earphone's own speaker and microphone, replacing the need for external audiometric equipment and professional操作
2Measurement precision
If traditional professional fitting process is used, then fitting accuracy can be maintained, but service cost pushes up hearing earphone cost
Solution Approach 1:
By enabling users to perform their own fitting through mobile applications and automated guidance, the system eliminates the need for expensive professional fitting services. The automated system uses algorithms to calculate target compensation gain values based on user age, gender, and hearing threshold data, removing the need for paid audiologist time while maintaining fitting accuracy
Solution Approach 2:
The patent uses the hearing earphone's own speaker and microphone to create a self-contained testing system. Instead of requiring expensive external pure tone test equipment, the system plays test tones through the earphone speaker and records the user's responses through the earphone microphone, copying the functionality of professional equipment into the consumer device itself
3Productivity
If automated fitting is implemented, then fitting efficiency and accessibility are improved, but professional skill requirement is reduced
Solution Approach 1:
The system incorporates automated feedback loops where the hearing earphone records the user's hearing threshold responses, the server calculates appropriate gain values, and the system guides the user through adjustments. This automated feedback mechanism replaces the need for professional audiologists to interpret test results and make manual adjustments, enabling lay users to complete the fitting process independently while maintaining scientific accuracy
