Apparatus Control Device Authorization Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote control devices for electrical apparatuses in buildings can inadvertently change the operational state of an apparatus if controlled by a different device after initial operation, leading to unintended changes.
Innovation Solution
An apparatus control device that associates mobile terminal identification information with controllable electrical apparatuses, ensuring that control commands are only transmitted if the mobile terminal is authorized to control the target apparatus, based on pre-set correspondence information and restriction conditions such as time zones, presence, or power consumption levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple mobile terminals can control any electrical apparatus, then ease of operation is improved, but reliability deteriorates due to unintended operational changes
Solution Approach 1:
The patent segments the control authority by dividing electrical apparatuses into different controllable groups based on mobile terminal identification. Each mobile terminal is assigned specific apparatuses it can control, creating distinct control zones. This segmentation resolves the contradiction by maintaining ease of operation within authorized scope while preventing unauthorized changes that would compromise reliability.
Solution Approach 2:
The patent applies local quality by assigning different control permissions to different mobile terminals for different electrical apparatuses. The control authority is not uniform across all devices but varies locally based on the specific terminal-apparatus pairing. This allows authorized terminals to operate apparatuses freely while blocking unauthorized terminals, thus maintaining both ease of operation and reliability.
2Reliability
If control restrictions are imposed on mobile terminals, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent implements preliminary action by pre-establishing correspondence relationships between mobile terminals and controllable electrical apparatuses before actual operation. The control permission settings are configured in advance, so that during operation, the system can automatically determine whether a terminal can control a specific apparatus without requiring real-time authorization checks. This preliminary setup ensures reliability through consistent access control while maintaining ease of operation by eliminating runtime permission verification.
3Adaptability or versatility
If all mobile terminals can control all electrical apparatuses, then adaptability is improved, but object-generated harmful factors increase due to unintended operational changes
Solution Approach 1:
The patent applies dynamics by making the control permission structure flexible and configurable rather than fixed. The correspondence between mobile terminals and electrical apparatuses can be dynamically adjusted based on user needs, time, or other conditions. This dynamic approach allows the system to adapt to different scenarios while maintaining reliability by ensuring that only authorized terminals can control specific apparatuses, thereby preventing harmful unintended changes.

AI summary
An apparatus control device includes a first communicator which communicates with a mobile terminal, a second communicator which communicates with a plurality of electrical apparatuses, a setter which sets correspondence information in which identification information of the mobile terminal is associated with identification information of an electrical apparatus controllable by the mobile terminal, and a controller which controls, when the first communicator receives a control request to control a target electrical apparatus from the mobile terminal, communication of the second communicator such that the second communicator transmits a control command to the target electrical apparatus if the identification information of the mobile terminal is associated with identification information of the target electrical apparatus, and such that the second communicator does not transmit the control command to the target electrical apparatus if the identification information of the mobile terminal is not associated with the identification information of the target electrical apparatus.
