Air conditioner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioners with bidirectional radio wave communication face issues where unintended operation control can occur due to accidental remote control operation, making it difficult to verify the operating status of the air conditioner, especially when the remote control is used in a different room or when the air conditioner is not in the same radio wave range.
Innovation Solution
The air conditioner system displays the operating status of the air conditioner main body and the result of communication on the remote control, allowing users to easily determine the status by checking the remote control, and includes features like pairing settings and log information management to ensure accurate operation control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If bidirectional communication using radio waves is implemented between the remote control and air conditioner main body, then operation control convenience is improved, but unintended operation control may occur due to accidental operation
Solution Approach 1:
The patent implements a feedback mechanism where the remote control receives and displays communication results from the air conditioner main body. After operation control is transmitted via radio waves, the remote control shows whether the communication succeeded or failed, providing immediate feedback to the user. This allows users to verify if unintended operation occurred and take appropriate action, resolving the reliability issue while maintaining operational convenience.
2Ease of operation
If the remote control displays operating status and communication results, then verification of air conditioner status becomes easier, but device complexity increases
Solution Approach 1:
The patent uses the remote control as an intermediary device that simplifies status verification for the user. Instead of requiring direct interaction with the air conditioner main body or complex monitoring systems, the remote control receives communication results from the main body and presents them in an easily readable format. This intermediary role reduces the perceived complexity for the user while enabling comprehensive status verification.

AI summary
An air-conditioner indoor unit (2) includes an RF module (21) that receives a control signal to control operation from a remote control (1), and an RF module (21) that transmits operating information of an air-conditioner indoor unit (2) to the remote control (1). The remote control (1) includes an RF module (11) that transmits a control signal of operation control to the air-conditioner indoor unit (2), an RF module (11) that receives operating information transmitted from the air-conditioner indoor unit (2), an LCD unit (15) that displays control content of operation control and operating information, a display controller (14c) that controls display content of the LCD unit (15), and a reception-time limiting unit (14b) that sets the RF module (11) in a reception standby state when the RF module (11) transmits a control signal and that cancels the state in a predetermined length of time. The display controller (14c) displays an error on the LCD unit (15) when communication between the remote control (1) and the air-conditioner indoor unit (2) is not established during the reception standby state.
