Solution Overview

Problem

The rapid advancement and global distribution of home devices create a need for improved quality management systems that can efficiently provide operation and maintenance instructions, troubleshooting procedures, and up-to-date information for both new and existing devices, as existing methods struggle to keep pace with the accelerating progress of technology.

Innovation Solution

A computer-based quality management platform that includes a knowledge repository with a knowledge graph and a query engine, which extracts and organizes information from various sources such as user manuals, social media, and customer service records, allowing for efficient querying and response to user requests regarding device operation and faults.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional quality management methods are used to manage home device information, then information can be stored and retrieved, but the system cannot keep pace with the accelerating progress of new devices and cannot efficiently distribute information globally

Engineering Contradiction:
Improveinformation distribution speedVSAvoidtime to update and distribute information
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent replaces traditional mechanical information distribution systems with an Internet-based electronic platform. The quality management platform uses web servers, databases, and electronic communication networks to distribute device information globally and instantly, eliminating the delays and inefficiencies of manual or traditional distribution methods.

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

Solution Approach 2:

The patent creates digital copies of device information, manuals, and support data that can be replicated and distributed infinitely across the network without degradation. This allows simultaneous distribution to unlimited users worldwide, keeping pace with rapid device proliferation.

Inventive Principle:
Principle #26Copying

2Reliability

If comprehensive information is maintained for both new and existing devices, then complete support is provided, but the complexity of managing and updating this information increases

Engineering Contradiction:
Improvecompleteness of device informationVSAvoidcomplexity of information management system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments device information into structured categories including device specifications, operation manuals, troubleshooting guides, and maintenance schedules. The system organizes data by device type, model, and functional category, making comprehensive information manageable through systematic segmentation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates a universal quality management platform that serves multiple functions: storing information, distributing updates, providing customer support, enabling device registration, and facilitating feedback collection. This multi-functional system manages comprehensive device information through a single integrated platform rather than separate systems.

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

3Ease of operation

If manual methods are used to distribute troubleshooting procedures and maintenance instructions, then information can be provided, but the process cannot keep pace with rapidly introduced new devices

Engineering Contradiction:
Improveease of information accessVSAvoidspeed of information delivery
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent replaces manual information distribution with automated electronic delivery systems. The platform uses web-based interfaces, email notifications, and automatic downloads to provide troubleshooting procedures and maintenance instructions instantly, eliminating the slowness of manual distribution methods.

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

Solution Approach 2:

The patent enables users to independently access and download the information they need through self-service functionality. Users can search for their device model, access manuals and troubleshooting guides, and obtain maintenance instructions without requiring manual intervention from support staff, thereby accelerating information delivery.

Inventive Principle:
Principle #25Self-service

AI summary

A quality management platform for home devices is implemented on a computer system and comprises a knowledge repository and a query engine. The knowledge repository includes a knowledge graph of nodes connected by edges. The nodes represent concepts relating to home devices and their operation and faults, and the edges represent relations between the concepts. The query engine receives requests relating to home devices, queries the knowledge graph based on the requests, and returns responses based on the query results.
