Solution Overview

Problem

Conventional language processing systems face speed, accuracy, and efficiency deficiencies in quickly disambiguating spoken utterances, often leading to slow and inaccurate results due to time-consuming queries to resolve user intent.

Innovation Solution

A hierarchical multi-tier digital platform with a processor and non-transitory memory, utilizing a multi-tier tree architecture database and natural language processing engine to route verbal requests by identifying matching modules and compiling a result set for comprehensive and tailored responses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If conventional language processing systems use traditional processing methods, then they can handle basic utterance processing, but they suffer from slow processing speed and inability to quickly disambiguate utterances

Engineering Contradiction:
Improveprocessing speedVSAvoidtime-consuming queries
Core Design Contradiction:
SpeedVSLoss of time

Solution Approach 1:

The patent segments the language processing system into multiple independent modules organized in a hierarchical tree structure with at least three tiers. Each module handles specific aspects of utterance processing, allowing parallel processing and faster disambiguation without requiring sequential time-consuming queries to the speaker.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary processing actions by pre-organizing processing modules in a hierarchical structure and pre-computing potential interpretations. This allows the system to quickly disambiguate utterances by selecting from pre-prepared options rather than engaging in time-consuming interactive queries.

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If conventional systems engage in time-consuming queries to disambiguate utterances, then they may achieve accurate results, but the processing time increases significantly

Engineering Contradiction:
ImproveaccuracyVSAvoidprocessing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

By segmenting the processing into hierarchical modules, the system can accurately disambiguate utterances at different levels of specificity without requiring time-consuming user queries. Each tier refines the interpretation progressively, achieving accuracy through structured processing rather than interactive clarification.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs partial disambiguation at each hierarchical tier, gathering sufficient information to make accurate decisions without completing exhaustive analysis. This allows the system to achieve adequate accuracy for practical purposes without the time cost of complete disambiguation.

Inventive Principle:
Principle #16Partial or excessive action

3Productivity

If conventional systems process utterances without hierarchical structure, then the system architecture is simpler, but the processing efficiency and accuracy deteriorate

Engineering Contradiction:
Improveprocessing efficiencyVSAvoidsystem architecture complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The hierarchical module segmentation improves processing efficiency by organizing functions into specialized tiers that can process information in parallel and progressively refine interpretations. The modular structure enables efficient resource utilization while maintaining manageable complexity through clear separation of concerns.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a hierarchical dimension to the system architecture, organizing modules across multiple tiers rather than using a flat structure. This dimensional organization improves processing efficiency by enabling progressive refinement and parallel processing while keeping each individual module relatively simple.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
