Home Appliance Command History Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home appliances fail to accurately perform previous operations as desired by users, as they simply rely on stored data without considering time changes, leading to unexpected re-execution of operations.
Innovation Solution
A home appliance system that includes a user input interface and a storage database to verify the type of command, determining whether to use stored data as is or generate new data based on command types, ensuring accurate re-execution of desired operations by considering time changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the home appliance simply accumulates data on previous operations in the history, then the previous operation function can be provided, but operations at a previous time unexpected to the user may be performed
Solution Approach 1:
The patent applies dynamics by making the history database structure adaptable and changeable. Instead of a static history storage, the system dynamically adjusts the history based on operation types, time intervals, and user behavior patterns. This allows the history to evolve and adapt to current usage contexts, ensuring that re-executed operations remain relevant and expected by users.
Solution Approach 2:
The patent changes parameters of the history database including time stamps, operation types, and validity periods. By tracking when operations were performed and what type of operation they were, the system can determine whether to include them in re-execution. Operations that exceed a certain time threshold or belong to categories that should not be re-executed are automatically excluded, improving reliability.
2Ease of operation
If the home appliance stores and re-executes operations from history, then user convenience is improved, but the result may differ from user expectation due to time lapse
Solution Approach 1:
The patent performs preliminary actions by storing not just the operation data but also contextual information such as time stamps, operation sequences, and validity indicators when operations are first recorded. This preliminary capture of temporal context ensures that when re-execution is requested, the system can evaluate whether the operation is still valid and relevant, preventing loss of temporal context.
Solution Approach 2:
The system provides feedback by evaluating the temporal context and operation type before re-execution. It determines whether an operation should be re-executed based on time intervals, operation categories, and current system state. This feedback mechanism ensures that only appropriate operations are re-executed, maintaining user expectations while preserving convenience.

AI summary
The present disclosure relates to a home appliance and an operating method thereof. The home appliance according to the present disclosure includes: a user input interface; a storage configured to store a database of a response history, and a controller configured to: in response to receiving an input requesting to perform a previous operation through the user input interface, verify whether a first operation, corresponding to the request for performing the previous operation, is present in the operation history; in response to there being the first operation, verify a type of a first command, mapped to the first operation, among commands included in the database; in response to the type of the first command being a first type, determine the first operation to be the previous operation; and in response to the type of the first command being a second type, generate a second operation corresponding to the first command, and determines the second operation to be the previous operation. Various other embodiments are also possible.
