Innovation Solution

Incorporating a digital active noise reduction unit with a data interface that allows for software and firmware updates, as well as parameter adjustments, enabling wireless or wired communication for updating and adapting noise reduction controls and audio signal reproduction settings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If active noise reduction is implemented in headsets/earphones, then noise reduction performance is improved, but the system cannot be updated or adapted to changing noise environments

Engineering Contradiction:

Improvenoise reduction performanceVSAvoidadaptability to changing noise environments

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements a data interface that enables dynamic updates of the active noise reduction system through software and firmware updates. This allows the system to adapt to changing noise environments over time without hardware modifications, resolving the contradiction between maintaining reliable noise reduction performance and enabling adaptability to new conditions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent allows for parameter adjustments and updates of the active noise reduction algorithms through the data interface. By enabling parameter changes via software updates, the system can optimize noise reduction performance for different noise environments while maintaining the core hardware architecture, thus resolving the contradiction between stability and adaptability.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If software and firmware updates are enabled, then adaptability and continuous improvement are achieved, but device complexity increases

Engineering Contradiction:

Improvesoftware update capabilityVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a data interface that serves multiple functions: it enables software updates, firmware updates, parameter adjustments, and communication between the active noise reduction unit and other system components. By making the interface universal and multi-functional, the patent adds update capability without proportionally increasing overall system complexity.
