Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional diagnostic system is used in home appliances, then error detection capability is limited, but user-friendly data communication and real-time error detection are improved
Solution Approach 1:
The patent introduces a tag device as an intermediary between the home appliance and the mobile device. The tag device stores diagnostic data and enables communication between the appliance system and the user's mobile device through NFC technology, making error detection and diagnosis user-friendly without requiring technical expertise
Solution Approach 2:
The patent replaces traditional mechanical or manual diagnostic systems with an electronic-based system using NFC (Near Field Communication) technology. This substitution enables wireless, contactless data transfer between the home appliance and mobile device, improving ease of operation while maintaining reliable error detection
2Ease of operation
If diagnostic data is stored and transmitted in real-time, then user convenience is improved, but data communication complexity increases
Solution Approach 1:
The patent extracts the diagnostic data storage and communication functions into a separate tag device. This extracted component handles all data storage and NFC communication operations, simplifying the overall system architecture while enabling real-time diagnostic data access for users
Solution Approach 2:
The tag device autonomously stores diagnostic data and manages NFC communication without requiring complex control logic in the main appliance system. The system performs self-service by automatically maintaining diagnostic data readiness for user access through simple NFC tapping

Implementation Method 1
A home appliance diagnosis system that includes a tag device for storing and transmitting state and diagnosis data, and a mobile device for receiving and displaying this data via Near Field Communication (NFC)
Data Source
AI summary
A home appliance and a method of controlling the same are provided. The home appliance may include a controller that processes state data. The state data may include raw data representing an operation state of the home appliance. The controller may also output diagnosis result data representing whether or not an error has occurred in the home appliance. A tag device including a tag storage device may store the state data and the diagnosis result data, and a transmitting and receiving device may transmit the state data and the diagnosis result data when an external device is tagged.
