Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional hearing devices provide limited predefined settings for self-fitting, then ease of operation is improved, but adaptability deteriorates

Engineering Contradiction:
Improveease of self-fittingVSAvoidcustomization options
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic fitting strategies that allow users to adjust parameters in real-time based on their hearing needs. The system transitions from static predefined settings to dynamic, user-adjustable parameters that can be modified on-the-fly, enabling both ease of operation and high adaptability simultaneously.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent enables users to modify multiple fitting parameters (gain, frequency response, compression ratios) independently rather than being constrained to fixed predefined settings. This parameter-level control provides extensive customization while maintaining user-friendly operation through systematic parameter adjustment.

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If hearing devices rely on hearing health care professionals for adjustments, then manufacturing precision is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvefitting accuracyVSAvoidease of adjustment
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The patent empowers users to perform their own fitting adjustments through intuitive controls and real-time feedback mechanisms. Users can independently modify fitting parameters without requiring professional intervention, achieving both high fitting accuracy and ease of operation through self-directed adjustment.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system incorporates real-time feedback loops that monitor user response to different fitting parameters and guide users toward optimal settings. This feedback mechanism ensures fitting accuracy while maintaining ease of operation by providing clear directional guidance during the self-fitting process.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If hearing devices use complex software and sophisticated models for fitting, then adaptability is improved, but device complexity increases

Engineering Contradiction:
Improvepersonalization capabilityVSAvoidsoftware complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the complex fitting process into discrete, manageable parameter groups (gain settings, frequency responses, compression parameters). This segmentation allows sophisticated personalization to be achieved through systematic adjustment of individual parameter groups rather than requiring users to navigate complex integrated software.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements a universal fitting framework that handles multiple hearing loss types and severity levels through a unified parameter adjustment system. This multi-functional approach provides extensive adaptability across different user needs while maintaining consistent, manageable device complexity through standardized control mechanisms.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Device complexity

If hearing devices offer limited predefined settings, then device complexity is reduced, but adaptability deteriorates

Engineering Contradiction:
Improvesystem simplicityVSAvoidpersonalization options
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent transforms the system from static predefined settings to dynamic user-adjustable parameters. This dynamic approach maintains relative system simplicity while dramatically increasing adaptability, as users can create personalized fitting configurations through straightforward parameter modification rather than selecting from limited presets.

Inventive Principle:
Principle #15Dynamics

AI summary

An exemplary hearing device is configured to be fit for a user. The hearing device maintains data representative of a first and a second fitting strategy for the hearing device, the first and the second fitting strategy comprising a first and a second set of values, respectively, for a plurality of parameters that specify an operation of the hearing device. The hearing device receives a value for a mixing setting that specifies a weighting between the first and the second fitting strategy. The hearing device determines, based on the value for the mixing setting, a custom fitting strategy comprising a custom set of values for the plurality of parameters, the custom set of values including combinations of the first and second sets of values that are weighted in accordance with the value for the mixing setting. The hearing device bases outputting of a signal on the custom fitting strategy.
