Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional voice assistant control is used, then users can control audio devices verbally, but the control process becomes inefficient and frustrating due to complex interfaces and pre-training requirements

Engineering Contradiction:
Improvevoice control efficiencyVSAvoidinterface complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts and removes the pre-training requirement from the voice control system. The ML model is designed to process user input directly without needing pre-training with user-specific data, eliminating a complex setup phase and simplifying the overall system architecture while maintaining voice control functionality.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the ML model processing into distinct modules: audio capture, ML model processing, and control action execution. This segmentation allows each component to be optimized independently and simplifies the overall system structure, making the voice control more efficient and easier to implement without requiring full pre-training.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If pre-trained ML models are used for voice control, then accuracy can be improved, but the time and resources required for pre-training increase significantly

Engineering Contradiction:
Improvecontrol accuracyVSAvoidpre-training time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-configuring the ML model with general audio processing capabilities and control logic before deployment. The model is prepared in advance with the necessary structure and parameters to accurately interpret user input and determine control actions, eliminating the need for time-consuming on-device pre-training while maintaining high accuracy.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent changes the operational parameters of the ML model to function effectively without pre-training. By adjusting the model's architecture and processing parameters, it achieves accurate control action determination directly from user input, sacrificing the time-intensive pre-training phase while preserving measurement precision through optimized parameter configuration.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If simple button control is used, then the interface remains simple, but controlling audio devices becomes limiting and less intuitive

Engineering Contradiction:
Improvecontrol flexibilityVSAvoidcontrol convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent substitutes mechanical button control with a voice-based control system using an ML model. This replacement provides significantly greater control flexibility and adaptability, allowing users to issue complex commands naturally through speech while maintaining ease of operation. The ML model processes diverse voice inputs and translates them into appropriate control actions for various audio device functions.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Various implementations include approaches for voice control in audio devices. In some cases, a method includes: listening, using at least one audio capture device, for user input to control at least one attribute of an audio device; routing the user input through a machine learning (ML) model to determine a control action for the at least one attribute based on the user input; and causing the determined control action to be performed, wherein the ML model need not have been pre-trained with the user input to determine the control action for the at least one attribute of the audio device.
