Domestic Appliance Wireless Service Mode Initiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Domestic appliances often require service mode access for maintenance, but conventional methods involve difficult-to-remember unique key sequences and varying entry methods across different appliances, complicating the process for technicians.
Innovation Solution
A domestic appliance with a control panel featuring a wireless transmitter and communication module that emits a predetermined code signal to identify the appliance and retrieve the necessary input sequence for entering service mode, facilitating a standardized and accessible service process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a unique key sequence is entered via user interface to place appliance into service mode, then service mode access is achieved, but the process becomes difficult to obtain or remember and varies between appliances
Solution Approach 1:
The patent replaces the mechanical/manual system of entering key sequences through physical button presses with an automated electronic system. The appliance controller automatically transmits the unique key sequence via wireless communication module to a remote terminal, eliminating the need for manual input and resolving the contradiction between reliable service access and ease of operation.
Solution Approach 2:
The appliance performs the service mode initiation automatically without requiring external manual input. The controller generates and transmits the unique key sequence autonomously to the remote terminal, allowing the system to serve itself in initiating the service mode connection process.
2Reliability
If conventional cable connection methods are used to access appliance for service, then secure physical connection is established, but the process is complicated and requires multiple cables
Solution Approach 1:
The patent extracts the key sequence transmission function from the physical cable connection process. The unique key sequence is transmitted wirelessly through the wireless communication module before the cable connection is established, separating the authentication phase from the physical connection phase and reducing overall system complexity.
Solution Approach 2:
The appliance controller performs preliminary action by automatically transmitting the unique key sequence to the remote terminal before the cable connection is physically established. This preliminary transmission of authentication data simplifies the overall service setup process by preparing the connection parameters in advance.
