Solution Overview
Problem
Conventional remote control systems for household electric appliances do not effectively handle overlapped reservations made from remote controllers and mobile terminals, leading to inefficiencies in operation start and stop times.
Innovation Solution
A household electric appliance and system that prioritize the earlier start or stop time when overlapped reservations are set from both remote controllers and mobile terminals, with a server apparatus communicating with these devices to ensure timely operation based on reserved settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the appliance accepts reservation settings from both remote controllers and mobile terminals independently, then user convenience and accessibility are improved, but conflicts arise when reservations overlap in time
Solution Approach 1:
The control unit proactively detects overlapping reservations before they are executed, compares the operation start times, and determines which reservation to prioritize. This preliminary detection and resolution mechanism prevents timing conflicts from occurring, ensuring reliable operation execution while maintaining the convenience of multiple input methods.
2Adaptability or versatility
If the appliance executes both overlapping reservations, then all user preferences are honored, but operation timing conflicts cause uncertainty and potential errors
Solution Approach 1:
The control unit changes the operational parameters by comparing operation start times and selecting the earlier time when overlaps occur. This parameter-based decision rule (selecting earlier start time) provides a clear, deterministic method for resolving conflicts, eliminating timing uncertainty while preserving user flexibility in making reservations through multiple channels.
3Measurement precision
If the appliance prioritizes the earlier start time in overlapping reservations, then operation timing precision is improved, but some user preferences may be overlooked
Solution Approach 1:
The control unit implements a feedback mechanism that monitors reservation inputs from both remote controllers and mobile terminals, detects overlaps, and applies a consistent rule (selecting earlier start time) to resolve conflicts. This feedback loop ensures precise timing execution while maintaining system adaptability, as users can still make reservations through either interface and the system will appropriately handle their preferences according to the established resolution rule.

AI summary
Provide are a household electric appliance, household electric system and server apparatus that perform operation start or stop at reserved set times and that are convenient with regard to reserving operation. A household electric appliance capable of a reserved operation of performing an operation start or stop at a set time comprises: a receiving unit that receives a setting signal indicative of an operation start time in the reserved operation of the household electric appliance from each of a remote controller and a mobile terminal; a storage unit that stores the setting signal; and a control unit that controls operation of the household electric appliance. The control unit, in the case of overlapping of an operation time zone defined by the setting signal from the remote controller and the operation time zone defined by the setting signal from the mobile terminal, selects the earlier time and performs the operation start.
