Solution Overview

Problem

Existing communication systems lack the ability to effectively utilize contextual attributes from interactions to generate tailored and accurate responses in real-time, leading to suboptimal customer engagement and service provision.

Innovation Solution

A host platform utilizing large language models (LLMs) to identify and vectorize contextual attributes from customer interactions, enabling retrieval and generation of customized responses based on previous conversations, mood, and items of interest, and storing these in a vector database for enhanced real-time communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional communication systems are used, then system simplicity is maintained, but the ability to generate personalized responses based on contextual attributes is lost

Engineering Contradiction:
Improveability to generate personalized responsesVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a vector database as an intermediary component between the communication system and the response generation mechanism. This vector database stores contextual attributes in vector format, enabling the system to retrieve and utilize historical interaction data without directly complicating the core communication flow. The vector database acts as a mediator that transforms unstructured interaction data into structured, queryable representations.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the communication system into distinct functional modules: interaction content reception, contextual attribute identification, vectorization processing, vector database storage, and response generation. This segmentation allows each component to perform its specific function independently, making the overall complex system manageable and maintainable while enabling personalized response capabilities.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If contextual attributes are identified and stored for every interaction, then response accuracy is improved, but data processing time and storage requirements increase

Engineering Contradiction:
Improveresponse accuracyVSAvoiddata processing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by vectorizing and storing contextual attributes immediately when interactions occur, rather than processing them in real-time when needed. The vector database pre-stores these transformed representations, so when a response is needed, the system can quickly retrieve pre-processed vector data without performing time-consuming analysis at the moment of interaction.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces traditional text-based contextual analysis with vector-based representation. Instead of storing and searching through raw text interactions, the system transforms interaction data into numerical vector formats that enable efficient mathematical operations and similarity searches, significantly reducing processing time while maintaining or improving accuracy.

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

3Productivity

If vector databases and LLMs are implemented, then customer engagement is improved, but system cost and complexity increase

Engineering Contradiction:
Improvecustomer engagementVSAvoidsystem architecture complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent makes the vector database serve multiple functions within the communication system: storing historical interaction data, enabling contextual attribute retrieval, supporting response generation, and facilitating pattern recognition. This multi-functionality reduces the need for separate specialized components, thereby managing complexity while delivering enhanced customer engagement through personalized responses.

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