Wireless Air Conditioner Remote Display for Communication Errors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioners with bidirectional radio wave communication face issues such as unintended operation changes when the remote control is used from another room, making it difficult to verify changes and preventing accidental startup, due to lack of clear status indication.
Innovation Solution
The air conditioner system includes a remote controller with a display unit that shows the operating status and communication results, using a reception-time limiting unit or power-saving standby unit to set the receiver in a standby state and display error indications when communication fails, ensuring the user can determine the air conditioner's status by checking the remote control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If bidirectional communication using radio waves is implemented between remote control and air conditioner, then operation control functionality is improved, but unintended operation changes occur when remote control is used from another room
Solution Approach 1:
The patent implements a feedback mechanism where the air conditioner transmits operating status information back to the remote control via radio waves. The remote control displays this status information to provide users with feedback about the actual operation state, allowing them to verify whether unintended operations occurred and to understand the current status of the air conditioner.
Solution Approach 2:
The patent introduces a display unit on the remote control as an intermediary that mediates between the air conditioner's operation and the user's perception. This display unit shows operating status information, serving as a communication bridge that confirms whether operations were executed as intended, thereby preventing unintended operation changes.
2Adaptability or versatility
If radio wave communication is used for remote control operation, then control flexibility is improved, but it becomes difficult to verify operation status and communication success
Solution Approach 1:
The air conditioner's operation status information is transmitted back to the remote control through radio wave communication, and this information is displayed on the remote control's display unit. This feedback loop ensures that operation status and communication success are clearly communicated to the user, preventing information loss despite the use of wireless communication.
Solution Approach 2:
The remote control serves multiple functions: it transmits control signals to the air conditioner, receives operating status information, and displays both control content and status information. This multi-functionality ensures that verification of operation status and communication success is integrated into the existing remote control device.
3Speed
If the remote control receiver remains in standby state continuously, then communication responsiveness is improved, but power consumption increases
Solution Approach 1:
The remote control receiver operates in periodic intervals rather than continuously. It switches between standby state and reception state at predetermined intervals, allowing it to maintain communication responsiveness while significantly reducing power consumption during periods when reception is not required.
Solution Approach 2:
The receiver's operational state is dynamically adjusted based on communication needs. The system transitions between different states (standby and reception) depending on whether communication is required, optimizing the balance between responsiveness and power consumption.

AI summary
An air conditioner includes a remote controller that performs bidirectional communication using radio waves with an air-conditioner main body. The air-conditioner main body includes a main-body receiver that receives a control signal from the remote controller and a main-body transmitter that transmits operating information to the remote controller. The remote controller includes a remote-control transmitter that transmits a control signal to the main-body receiver, a remote-control receiver that receives the operating information from the main-body transmitter, a display unit that displays the operating information, a display controller that controls the display unit. The display controller displays, on the display unit, the operating information when the display controller receives the operating information from the main-body transmitter, and an indication of communication error when the display controller failes to receive the operating information, when communication between the remote controller and the air-conditioner main body is not established.
