Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods fail to efficiently track, summarize, and analyze equipment faults caused by preset parts in household appliances, leading to inefficiencies in data collection and improvement processes.
Innovation Solution
A method and device that acquire operating parameter information and fault codes from household appliances, determine fault rates, and transmit them to a fault counting system when exceeding a preset threshold, enabling effective tracking and analysis of faults across appliances equipped with preset parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If after-sales personnel manually analyze and feedback faults on site, then fault information can be obtained, but the efficiency is not high and fault tracking is incomplete
Solution Approach 1:
The system implements automated feedback loops where fault data from multiple sources (manual reports, IoT devices, warranty cards) is continuously collected, processed, and fed back to improve fault tracking completeness and analysis efficiency. The feedback mechanism ensures that fault information flows systematically from collection to analysis to actionable insights.
Solution Approach 2:
The patent introduces an intermediary fault management system that acts as a bridge between various data sources (after-sales personnel, IoT devices, manufacturing systems) and the final analysis outputs. This intermediary system standardizes and consolidates fault data, enabling efficient tracking and analysis without requiring direct manual intervention for each fault event.
2Reliability
If preset parts are applied to household appliances, then product quality can be improved, but fault tracking and analysis of these parts cannot be performed
Solution Approach 1:
The system performs preliminary actions by pre-configuring tracking mechanisms for preset parts before they are deployed in appliances. Warranty card binding, IoT device association, and manufacturing data linkage are established in advance, ensuring that when faults occur, the preset parts can be automatically identified and tracked without requiring additional manual setup.
Solution Approach 2:
The fault management system is designed with universal capabilities to handle multiple types of data sources (manual reports, IoT sensors, warranty information, manufacturing data) and multiple part types simultaneously. This multi-functional approach enables comprehensive tracking of preset parts across different appliance models and failure modes, maintaining reliability while enabling complete fault analysis.
3Productivity
If manual fault collection methods are used, then implementation is simple, but data collection efficiency and analysis capability are insufficient
Solution Approach 1:
The system segments fault data collection into distinct modular channels: manual after-sales reporting, automated IoT device monitoring, warranty card information extraction, and manufacturing data integration. Each segment handles specific data types independently, then all segments feed into a unified analysis platform. This segmentation improves data collection efficiency while keeping the overall system complexity manageable through clear separation of concerns.
