Solution Overview
Problem
Existing home appliance systems face challenges in accurately transmitting fault or failure information due to location restrictions, signal interference, and data loss, particularly in outdoor installations, where conventional methods attenuate signals and suffer from environmental conditions.
Innovation Solution
The implementation of a sound output device and sound guide system within home appliances, such as laundry treatment machines, which converts product information into sound information and efficiently transmits it through a sound path to an external controller via an existing input device connection, ensuring accurate and clear signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional signal transmission methods are used in outdoor installations, then the home appliance can be installed flexibly, but signal attenuation and interference occur due to environmental conditions
Solution Approach 1:
The patent replaces electrical signal transmission with acoustic signal transmission. The sound output device converts electrical fault information into acoustic waves that propagate through air to the external controller, eliminating the need for direct electrical connection and avoiding signal attenuation issues in outdoor environments
Solution Approach 2:
The patent introduces acoustic waves as an intermediary medium for transmitting fault information. The sound guide structure acts as a mediator that efficiently couples the sound output device to the external controller, enabling reliable communication without direct electrical contact
2Loss of information
If electrical signals are transmitted through telephone networks, then fault information can be transmitted remotely, but data loss and signal interference occur
Solution Approach 1:
The patent extracts the fault information transmission function from the complex telephone network system and implements it directly through acoustic waves. This eliminates the need for telephone network infrastructure, modems, and complex communication protocols, reducing both data loss and system complexity
Solution Approach 2:
The patent creates a simplified copy of the communication function using acoustic waves instead of electrical signals through telephone networks. The sound guide structure replicates the information transmission capability in a more reliable and simpler manner
3Reliability
If sound output devices are added to transmit fault information, then transmission reliability improves, but device complexity increases
Solution Approach 1:
The patent merges the sound output device with the existing control panel structure. The sound guide is integrated into the control panel housing, and the sound output device is positioned to utilize existing openings or spaces, thereby adding transmission capability without significantly increasing overall device complexity
Solution Approach 2:
The sound guide structure serves multiple functions: it guides acoustic waves from the sound output device to the external controller, provides structural support, and integrates with the control panel design. This multi-functionality reduces the need for additional separate components

Data Source
AI summary
A home appliance and home appliance system are provided. The home appliance may include an input device, through which an input signal is received from a user, and a control panel, into which the input device is inserted and connected, including a sound through-hole through which sound information passes. The home appliance may further include a sound output device disposed on a rear surface of the control panel that outputs the sound information corresponding to product information of the home appliance through the sound through-hole to outside of the home appliance. A gap may be formed between the input device and the sound through-hole into which the input device is inserted. Therefore, the sound information output from the sound output device may be transmitted to the outside through the gap. The home appliance may further include a sound guide, such that the sound information transmitted from the sound output device may be efficiently transmitted to the sound through-hole.
