Home Appliance Acoustic Program Update System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home appliance systems face challenges in updating product operating programs, particularly when users cannot accurately diagnose and update faults, and there are location restrictions for connecting appliances to telephone networks, making it difficult to upgrade programs efficiently.
Innovation Solution
A home appliance system that allows users to output sound-based product information, which is received and analyzed by a management device to determine if an update is necessary, and then sends acoustic signals with update information for the user to update the appliance's program, using a sound input device, inverse conversion device, and controller to facilitate remote program updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users call service center or visit service center to update product operating program, then program update can be performed, but it requires on-site service visits and cannot be done remotely
Solution Approach 1:
The system enables users to update product operating programs themselves through remote communication. The user terminal collects product information, determines update needs, and transmits update programs back to the home appliance, eliminating the need for service center visits and allowing users to perform updates independently at any location.
Solution Approach 2:
A user terminal acts as an intermediary between the home appliance and the service center. It collects product information from the appliance, analyzes whether updates are needed, and if so, retrieves and transmits the update program back to the appliance, enabling remote updates without direct service center involvement.
2Adaptability or versatility
If modem is connected to home appliance for fault information transmission, then fault information can be sent to service center, but home appliances installed outdoors cannot be connected to telephone network
Solution Approach 1:
The user terminal serves multiple functions: it collects product information from the home appliance, determines whether updates are needed, retrieves update programs, and transmits them back to the appliance. This multi-functional approach replaces the specialized modem connection, enabling communication for appliances in any location including outdoor installations.
Solution Approach 2:
The physical modem connection to telephone network is replaced with a wireless communication system using a user terminal. This substitution eliminates the need for physical connection infrastructure, allowing home appliances to communicate fault information and receive updates regardless of their installation location.
3Measurement precision
If user cannot accurately diagnose fault, then correct program update cannot be performed, but with the system user can accurately diagnose and update
Solution Approach 1:
The system implements feedback by having the user terminal collect product information from the home appliance, analyze it to determine whether updates are needed, and then transmit appropriate update programs. This feedback loop ensures accurate fault diagnosis and appropriate update selection without requiring users to understand complex diagnostic procedures.
Solution Approach 2:
The user terminal acts as an intelligent intermediary that handles the complex analysis of product information and determination of update needs. This shields users from complexity while enabling accurate fault diagnosis and appropriate program updates through automated decision-making processes.

AI summary
A home appliance and a home appliance system are provided. The home appliance receives input of a sound including update information, and updates a product operating program. The home appliance system receives a sound including product information from the home appliance, judges whether to update the product operating program of the home appliance, and transmits update information.
