Remote controller for air conditioner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote controls for air-conditioning apparatuses with double liquid-crystal panels require increased size and weight to display detailed operating conditions, as they need to show information from both panels simultaneously, leading to an unnecessary enlargement of the device.
Innovation Solution
A remote control design that includes a cover opening/closing detection unit to switch between an enlarged display screen and a detail display screen based on the cover's position, allowing only necessary information to be displayed, thus avoiding the need for overlapping information and maintaining a compact size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the detail display unit displays both detailed operating conditions and enlarged display content simultaneously, then complete information is provided, but the display screen size increases
Solution Approach 1:
The patent implements dynamic display switching between two modes: when the cover is closed, the display shows an enlarged view of operating conditions; when the cover is opened, it switches to show detailed operating conditions. This dynamic switching allows the same display area to serve different functions, providing complete information without permanently increasing display screen size
Solution Approach 2:
The display alternates between enlarged display mode and detailed display mode based on the cover state. This periodic switching between different display configurations allows the system to provide both enlarged and detailed information sequentially, ensuring information completeness while maintaining a compact display area
2Loss of information
If the display screen size increases to show all information, then information completeness is improved, but the remote control weight increases
Solution Approach 1:
The system uses dynamic display switching based on cover state to provide different information views. When the cover is closed, it shows enlarged display; when opened, it shows detailed information. This eliminates the need for a permanently larger display, thereby preventing unnecessary weight increase while maintaining full information display capability
3Loss of information
If the display screen size increases to show all information, then information completeness is improved, but the remote control size increases
Solution Approach 1:
The patent employs dynamic display mode switching where the same display area shows enlarged information when the cover is closed and detailed information when the cover is opened. This dynamic adaptation allows complete information to be displayed without permanently increasing the remote control's physical dimensions, keeping it compact and portable

AI summary
A remote control for an air-conditioning apparatus includes: an outer button to be operated by a user for changing an operating condition of an air-conditioning apparatus body; an inner button to be operated by the user for changing the operating condition; a cover that is openable and closable and is configured to cover the inner button; a cover opening/closing detection unit configured to detect opening/closing of the cover; a display unit configured to display an enlarged display screen displaying at least one of an operation mode, a set temperature and a set humidity, and a detail display screen displaying a function of the inner button; and a display switching unit configured to, when the cover opening/closing detection unit detects that the cover is closed, make the display unit display the enlarged display screen, and when the cover opening/closing detection unit detects that the cover is open, make the display unit display the detail display screen.
