Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminals and home appliances lack an efficient method for easily displaying management and diagnostic data screens based on sound output, hindering user convenience in fault diagnosis and data access.
Innovation Solution
A mobile terminal with a display, communication unit, microphone, and controller that transmits requests for management and diagnostic data to home appliances and displays corresponding screens based on sound outputs, while home appliances include a memory, communication unit, and sound output unit to provide data in audible form.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If home appliances output data through traditional display interfaces, then data can be viewed, but user convenience and ease of operation deteriorate when accessing management and diagnostic data
Solution Approach 1:
The patent replaces traditional mechanical display interfaces with acoustic output. The home appliance converts management and diagnostic data into sound waves that can be captured by the mobile terminal's microphone, transforming visual information access into an auditory communication channel. This substitution enables easier access to diagnostic data without requiring complex interface interactions.
Solution Approach 2:
The patent introduces sound waves as an intermediary medium between the home appliance and the mobile terminal. Instead of direct visual display or wired data transmission, the appliance outputs data as acoustic signals that the mobile terminal captures and processes. This intermediary approach simplifies the interaction mechanism while maintaining data accessibility.
2Loss of information
If home appliances provide comprehensive management and diagnostic data, then data completeness improves, but device complexity increases
Solution Approach 1:
The patent extracts only the necessary management and diagnostic data from the home appliance system and converts it into acoustic signals. Instead of transmitting all possible data types through complex protocols, the system selectively outputs only the relevant information needed for monitoring and diagnosis, reducing overall system complexity while maintaining data completeness for essential functions.
Solution Approach 2:
The patent changes the parameter of data representation from visual/display-based to acoustic/sound-based. By transforming data into sound wave parameters (frequency, amplitude, duration), the system simplifies the transmission mechanism while preserving the completeness of information. The mobile terminal then converts these acoustic parameters back into readable data formats.

AI summary
A mobile terminal includes a display, a communication unit, a microphone, and a controller configured to perform a control operation to transmit a request for management data to an artificial Intelligence home appliance through the communication unit according to a management mode input and to display a management data screen on the display based on first sound acquired from the home appliance, and perform a control operation to transmit a request for diagnostic data to the home appliance through the communication unit according to a diagnosis mode input and to display a diagnostic data screen on the display based on second sound acquired from the home appliance. The management data screen and diagnostic data screen may be easily displayed based on the sound output from the home appliance.
