Solution Overview

Problem

Existing agent-type AI systems using generative AI struggle with controlling task execution propriety and situation through interactive dialogue, lack long-term storage of dialogue content, require specific and detailed user instructions, and often make unrealistic task determinations due to semantic similarity comparisons.

Innovation Solution

An agent system utilizing generative AI is configured with a dialogue unit, solution unit, execution unit, and monitoring unit, enabling autonomous task decomposition and execution, long-term storage of dialogue logs, and interactive task correction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple highly specialized AI agents are provided for respective services, then service specialization and response accuracy are improved, but system complexity and difficulty in realizing comprehensive response increase

Engineering Contradiction:
Improveresponse accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system segments AI agents into specialized service agents (e.g., reservation agent, recommendation agent) and a centralized task management agent. Each service agent handles specific tasks with high accuracy, while the task management agent coordinates them, resolving the contradiction between specialization and system complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A task management agent is introduced as an intermediary between the user and multiple specialized service agents. This mediator receives user instructions, decomposes them into subtasks, and assigns them to appropriate service agents, enabling comprehensive response without requiring the user to manage complex agent interactions directly.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If detailed user instructions are required for each task, then task execution precision is improved, but ease of operation and user burden deteriorate

Engineering Contradiction:
Improvetask execution precisionVSAvoiduser operation ease
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The task management agent performs preliminary actions by automatically decomposing user instructions into detailed subtasks and assigning them to appropriate service agents. This eliminates the need for users to provide detailed instructions manually, improving ease of operation while maintaining task execution precision through automated task breakdown.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system enables self-service by allowing the task management agent to autonomously analyze user instructions, determine required subtasks, and allocate them to suitable service agents without user intervention. This automated self-organization maintains precision while significantly improving ease of operation.

Inventive Principle:
Principle #25Self-service

3Productivity

If abstract user instructions are autonomously decomposed into specific tasks, then productivity and ease of operation are improved, but reliability of task determination deteriorates

Engineering Contradiction:
Improvetask execution efficiencyVSAvoidtask determination reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The task management agent implements feedback mechanisms by monitoring the decomposition and assignment process. It can review generated subtasks, verify their appropriateness, and adjust assignments based on service agent capabilities and current system state, thereby maintaining reliability while achieving high productivity through automated decomposition.

Inventive Principle:
Principle #23Feedback

4Adaptability or versatility

If generative AI is used for autonomous task decomposition and execution, then adaptability and ease of operation are improved, but measurement precision of task determination worsens

Engineering Contradiction:
Improvesystem adaptabilityVSAvoidtask determination precision
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system segments the task determination process into multiple stages: understanding user intent, decomposing into subtasks, and assigning to service agents. Each stage is handled by specialized components that maintain precision while leveraging generative AI's adaptability for overall task decomposition.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The task management agent serves as an intermediary that combines generative AI's adaptability in understanding diverse user instructions with rule-based precision in task decomposition and assignment. This mediator ensures that while the system is highly adaptable to different user needs, the actual task determination maintains precision through structured processing.

Inventive Principle:
Principle #24Intermediary (Mediator)
