Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If speech processing systems provide personalized content to users, then user engagement and satisfaction improve, but system complexity and computational resources increase

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

Solution Approach 1:

The patent replaces complex manual analysis and tracking of user interactions with automated machine learning models and natural language processing systems. These computational systems automatically analyze user feedback, determine personalization metrics, and adjust content delivery without requiring complex manual intervention or system reconfiguration.

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

Solution Approach 2:

The system automatically monitors user interactions, collects feedback, and adjusts personalization levels without requiring explicit user configuration. The speech processing system self-adjusts by analyzing user responses and autonomously determining appropriate personalization metrics, reducing the need for complex external control mechanisms.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If the system tracks and analyzes user feedback for personalization, then content relevance improves, but data processing time and computational load increase

Engineering Contradiction:
Improvepersonalization metric accuracyVSAvoiddata processing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system pre-processes and stores user feedback data as it is collected, organizing it into structured formats suitable for later analysis. By preparing data in advance and maintaining ready-to-analyze feedback repositories, the system reduces the computational burden and time required when personalization metrics need to be calculated.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Machine learning algorithms and natural language processing systems automatically analyze user feedback in real-time, replacing manual or batch processing methods. These computational models efficiently extract meaningful patterns from feedback data without requiring extensive human intervention or time-consuming analysis procedures.

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

3Adaptability or versatility

If the system provides highly personalized content, then user experience quality improves, but consistency across different user profiles becomes difficult to maintain

Engineering Contradiction:
Improvecontent personalizationVSAvoiduser experience consistency
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent implements a universal personalization framework that applies consistent methodology and metrics across all user profiles. The same speech processing algorithms, feedback analysis methods, and personalization calculation approaches are used for every user, ensuring methodological consistency even as personalized content varies by individual preferences and behaviors.

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

AI summary

Techniques for determining a level of personalization for content presented to users are described. A system may determine the level of personalization based on the number of users that receive the same content within a given time period, where if a large number of users receive the same content than the output is not personalized. The personalization level can be used to determine whether more or less personalized content is to be provided to a user, which may be on a domain-basis, user feedback basis, etc. The personalization level can also be used to prompt the user to configure certain settings which can help increase or decrease the amount of personalized content the user receives.
