Cooking Appliance Remote Control with Time-Limited Access for Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking appliances face issues with remote control functionality, including network errors, hacking, and difficulty in re-operating the appliance after cooking is finished, due to lack of time control and security measures in remote control modes.
Innovation Solution
A cooking appliance with a communicator, input unit, and controller that allows users to set remote control mode duration, extends it if needed, and blocks communication when the preset maximum time limit is exceeded, ensuring secure operation and preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote control is maintained indefinitely after cooking is finished, then user convenience is improved, but security risks and network errors increase
Solution Approach 1:
The patent implements dynamic remote control availability by allowing the cooking appliance to transition between different operational states. The remote control function is enabled during cooking operations and can be extended afterward based on user needs, but automatically expires after a maximum time limit. This dynamic approach balances user convenience with security by adapting the system's accessibility to the current operational context.
Solution Approach 2:
The system employs periodic time-based control where remote control access is granted for specific time intervals. The controller monitors the duration of remote control usage and automatically terminates access after a preset maximum time limit, creating a periodic pattern of enabled/disabled states that prevents indefinite access while allowing sufficient operational flexibility.
2Reliability
If remote control mode is automatically cancelled when cooking is finished, then security is improved, but user convenience deteriorates due to inability to re-operate the appliance
Solution Approach 1:
The patent applies preliminary action by pre-setting a maximum time limit for remote control availability that extends beyond the cooking operation duration. This allows users to initiate cooking operations remotely and have the appliance remain accessible for additional adjustments or monitoring after the cooking cycle completes, without requiring re-authentication or manual intervention.
Solution Approach 2:
The system changes the time parameter of remote control availability based on the cooking operation status. During active cooking, remote control is available in real-time. After cooking finishes, the system automatically extends availability by a preset time period, effectively changing the accessibility parameter from 'cooking-duration-only' to 'cooking-duration-plus-extension' without compromising security.
3Ease of operation
If remote control communication is continuously enabled, then ease of operation is improved, but susceptibility to hacking and network errors increases
Solution Approach 1:
The patent implements preliminary anti-action by proactively limiting remote control availability to a maximum time period rather than allowing continuous access. This preemptive measure reduces the window of opportunity for potential hackers or network errors to exploit the system, while still providing sufficient access time for legitimate user operations and monitoring.
Solution Approach 2:
The system rushes through the remote control session by enforcing a maximum time limit that compels users to complete their remote operations within a specified timeframe. This approach minimizes the duration of vulnerability to network threats while ensuring that essential user interactions can be completed efficiently without prolonged exposure to potential security risks.

AI summary
Disclosed herein is a cooking appliance including a communicator configured to perform communication with a terminal, an input unit configured to receive information from a user, and a controller configured to, when information on time until which remote control using the terminal is available is received via at least one of the communicator and the input unit, control the communication with the terminal. According to the present disclosure, by allowing a user to set a time at which a remote control mode is automatically cancelled after cooking is finished, the remote control is available during a time set by the user even after cooking is finished, and thus the usability of the remote control mode can be improved. According to the present disclosure, by limiting performance time of the remote control mode to be within a preset amount of time and limiting an infinite input of a remote control command into a terminal while the remote control mode is activated, a network error can be prevented, and erroneous operation of a cooking appliance due to hacking can be prevented.
