Solution Overview
Problem
Traditional smart family control systems lack the ability to set and control electrical apparatuses based on user-specific time habits, leading to inflexible operation and mismatched activation times for devices like air-conditioning and television.
Innovation Solution
A control system that includes a sensing device and operation devices connected via a trigger policy, where the sensing device detects environmental changes and generates trigger instructions based on stored time data to execute corresponding actions at preset times, allowing users to set relationships between devices according to their habits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional real-time simultaneous action technology is used to control electrical apparatuses, then devices can be controlled remotely through network connection, but devices cannot be activated at different predetermined times according to user habits
Solution Approach 1:
The patent applies preliminary action by pre-configuring trigger policies with predetermined time delays in the control device. When a triggering event occurs (e.g., door sensor detection), the system automatically executes a sequence of device activations at predetermined times without requiring real-time user intervention. This resolves the contradiction by enabling flexible timed control while maintaining ease of operation through automated policy-based control.
Solution Approach 2:
The patent implements dynamics by introducing time-varying control capabilities where device activation times are dynamically determined based on predetermined time delays from triggering events. The system transitions from static real-time simultaneous control to dynamic timed sequential control, allowing different devices to be activated at different times according to user-defined policies while maintaining operational simplicity.
2Ease of operation
If devices are controlled to activate simultaneously when one device is triggered, then control operation is simplified, but user-specific time preferences and life habits cannot be accommodated
Solution Approach 1:
The system applies preliminary action by pre-configuring trigger policies that include time delay parameters and device sequences before execution. Users define their preferred timing patterns in advance, and the system automatically applies these predetermined settings when triggering events occur. This maintains operational simplicity while accommodating user-specific time preferences through pre-established policies.
Solution Approach 2:
The patent applies parameter changes by introducing time delay parameters into the control system. Instead of fixed simultaneous activation, the system allows flexible adjustment of activation time parameters for different devices based on user-defined policies. This enables the system to adapt to various user habits by changing the time parameter while maintaining simple policy-based operation.
3Adaptability or versatility
If time-based periodic control is implemented to accommodate user habits, then flexibility and adaptability are improved, but system complexity increases due to additional time management functions
Solution Approach 1:
The patent applies the intermediary principle by introducing a control device as a mediator between triggering events and target electrical apparatuses. The control device contains the time management logic and trigger policies, isolating the time-based control complexity from both the sensors and the controlled devices. This allows flexible time-based control while keeping the overall system architecture relatively simple through centralized policy management.
Solution Approach 2:
The system applies self-service by enabling automated execution of timed device activations based on pre-configured trigger policies. Once policies are defined, the system automatically determines activation times and executes device control without requiring continuous user intervention or complex real-time processing. This reduces operational complexity while maintaining flexibility through self-automated time-based control.
Data Source
AI summary
The present invention is to provide a control system including a sensing device capable of periodically driving a corresponding operation device based on a trigger policy, wherein the sensing device and the operation device have the same trigger policy stored therein. The control system is characterized in that the trigger policy at least includes a trigger code, a time data (such as “after 15 minutes”) and an operation data (such as “turn on a lamp”). When the sensing device detects a sensing signal, the sensing device generates and transmits a trigger instruction to the operation device. When the operation device determines that a trigger code carried in the trigger instruction matches with a second identification code stored therein, the operation device calculates an expiration time of the time data based on the current time, and then executes an action corresponding to the operation data at the expiration time.
