Hearing Aid Fitting System Hash Key Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional hearing aid fitting methods are time-consuming due to the need to read out and verify large amounts of data, which can be prone to errors and inefficiently handled, leading to prolonged fitting times.
Innovation Solution
A method involving the generation and comparison of hash keys for data stored in the hearing aid and an external memory to verify data integrity, allowing for quicker validation and reduced data transfer, thereby shortening the fitting process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional data readout and verification methods are used, then data integrity can be ensured, but fitting time is significantly increased
Solution Approach 1:
The patent extracts the essential verification information from the complete data set by generating hash keys. Instead of reading and verifying all hearing aid data, the system extracts compact hash representations that capture the essential integrity information, dramatically reducing verification time while maintaining reliability
Solution Approach 2:
The patent transforms the verification approach by changing the parameter being verified from complete data sets to condensed hash key representations. This parameter transformation allows verification to be performed on compact data structures rather than large audio processing data, resolving the contradiction between thorough verification and time efficiency
2Measurement precision
If complete data is transferred between hearing aid and fitting device, then verification accuracy is improved, but data transfer time and complexity increase
Solution Approach 1:
The patent creates hash key copies of the complete data sets stored in both the hearing aid and the fitting device. These hash copies serve as efficient verification representations that maintain the essential integrity information without requiring transfer of the complete original data sets, thus reducing transfer time while preserving verification accuracy
3Reliability
If traditional verification methods are used, then data correctness can be confirmed, but processing complexity and time are increased
Solution Approach 1:
The patent replaces the mechanical approach of reading, transferring, and comparing complete data sets with a computational hash-based verification system. This substitution uses cryptographic hash functions to generate compact verification keys, simplifying the processing complexity while maintaining or improving verification reliability through more robust error detection capabilities
