Washing Machine Remote Setting Control to Reduce Engineer Visit Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washing machines require engineer visits for setting value changes, leading to time and cost inefficiencies for both users and manufacturers, as users often need to adjust settings to resolve issues that could be addressed through remote control.
Innovation Solution
A washing machine equipped with a communicator, storage, and controller that allows remote change of setting values, enabling users to modify settings without engineer intervention, including adjustments to detergent input, LED lighting, sound output, and drum rotation based on received signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If engineer visits are used to change setting values and resolve faults, then reliable fault resolution is achieved, but time and cost efficiency deteriorate
Solution Approach 1:
The washing machine automatically transmits fault information and usage history to the manufacturer's server, which then automatically determines and transmits appropriate setting values back to the washing machine, eliminating the need for engineer visits and enabling self-service fault resolution
Solution Approach 2:
A communication system acts as an intermediary between the washing machine and the manufacturer's server, enabling automatic transmission of fault information and setting values, thereby resolving faults without requiring physical engineer intervention
2Ease of repair
If engineer visits are dispatched based on user inquiry contents, then fault resolution is provided, but cost efficiency deteriorates
Solution Approach 1:
The system performs preliminary analysis of fault information and usage history on the server side before dispatching engineers, automatically determining appropriate setting values in advance, which prevents unnecessary engineer dispatches and reduces costs
Solution Approach 2:
The system establishes a feedback loop where usage history and fault information are continuously transmitted to the server, which analyzes the data and provides appropriate setting values back to the washing machine, enabling cost-effective automated fault resolution
3Loss of time
If setting values are changed remotely through communication, then time and cost efficiency improve, but system complexity increases
Solution Approach 1:
The communication unit serves multiple functions including transmitting fault information, receiving setting values, and enabling remote control operations, thereby managing complexity through multi-functionality rather than adding separate dedicated components for each function

AI summary
The present disclosure is directed to providing a washing machine that can change a setting value stored in advance in the washing machine remotely from the outside, it is possible to quickly solve the problem without an engineer's visit in a counselling process with a user, and increase the user's satisfaction by reducing the time and cost waste, a system including the same and a method of controlling the washing machine. The washing machine includes a communicator configured to communicate with the outside; a storage configured to store a setting value; and a controller configured to change the setting value stored in the storage based on the setting value received by the communicator, and to control the washing machine based on the changed setting value.
