Bidirectional Wireless Communication for Electric Blanket Status Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric blankets lack bidirectional communication between remote controllers and mobile terminals, leading to asynchronous operation and display, which can result in incorrect usage and reduced service life.
Innovation Solution
An electric blanket system with a first and second wireless module, a main control circuit, and a display circuit that allows for bidirectional communication between the electric blanket body and remote controller, enabling simultaneous display of operating information on either device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electric blanket is controlled by a remote controller with unidirectional communication, then the control operation can be performed, but the operation status cannot be fed back to the mobile terminal for synchronous display
Solution Approach 1:
The patent implements bidirectional communication between the remote controller and mobile terminal, enabling the electric blanket to send operation status feedback to the mobile terminal. The main control circuit transmits real-time status information including heating state, temperature settings, and operational mode back to the user's mobile device, ensuring synchronous display and eliminating information loss.
2Device complexity
If the electric blanket uses unidirectional control from remote controller, then the device structure can be simple, but the display operation is not synchronous leading to wrong operations
Solution Approach 1:
The system establishes a feedback loop where the main control circuit continuously monitors and transmits operational status to the mobile terminal. This includes real-time data on heating element state, selected temperature levels, and active functions, allowing users to verify control actions and prevent erroneous operations through synchronous visual confirmation.
3Loss of information
If the electric blanket implements bidirectional communication, then the operation status can be displayed synchronously, but the communication system becomes more complex
Solution Approach 1:
The remote controller serves multiple functions: it acts as both a control interface for user input and a display terminal for receiving and showing operation status feedback. The wireless communication module handles both transmitting control commands from the user and receiving status information from the electric blanket, consolidating multiple functions into existing components without requiring separate dedicated systems.
4Duration of action of stationary object
If the electric blanket uses conventional unidirectional control, then the service life may be shorter due to wrong operations, but the communication protocol can be simple
Solution Approach 1:
The bidirectional communication system provides real-time feedback on operational status, allowing users to confirm that control actions are executing as intended. This prevents wrong operations that could damage the electric blanket or create unsafe conditions, thereby extending service life through error prevention rather than through complex structural modifications.
