Remote control for air-conditioning apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote controls for air-conditioning apparatuses with double liquid-crystal panels display both detailed and enlarged operating conditions simultaneously, leading to increased size and weight due to overlapping information on the display screens.
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, allowing the display unit to show only necessary information based on the cover's open or closed state, eliminating the need for overlapping displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the detail display unit displays both detailed operating conditions and enlarged display contents simultaneously, then complete information is provided, but the display screen size and remote control size increase
Solution Approach 1:
The patent applies dynamics by making the display content switchable between two modes: when the cover is closed, the display shows enlarged operating conditions; when the cover is opened, the display switches to show detailed operating conditions. This dynamic switching allows the same display area to serve different functions based on usage context, eliminating the need for a larger fixed display area while maintaining information completeness.
Solution Approach 2:
The patent implements periodic action through the regular opening and closing of the cover, which triggers periodic switching between display modes. Each cover opening/closing cycle activates a corresponding display mode change, allowing the system to provide different information densities at different times based on user interaction patterns.
2Loss of information
If the detail display unit displays both detailed operating conditions and enlarged display contents simultaneously, then complete information is provided, but the remote control weight increases
Solution Approach 1:
The dynamic display switching mechanism allows the remote control to maintain a lightweight design by not requiring additional display hardware for showing detailed information. The same display unit dynamically adapts its content based on cover position, eliminating the need for extra heavy components that would be required to display all information simultaneously on a larger screen.
3Ease of operation
If the cover opening/closing detection unit and display switching unit are added, then display optimization is achieved, but device complexity increases
Solution Approach 1:
The system applies self-service by automatically detecting cover opening/closing actions and autonomously switching display modes without requiring user intervention. The cover opening/closing detection unit triggers the display switching unit to automatically select the appropriate display mode, making the system self-regulating and reducing the need for complex user interface controls.
Solution Approach 2:
The patent implements feedback through the cover opening/closing detection unit that continuously monitors the cover position and provides feedback to the display switching unit. This feedback loop enables the system to automatically adjust display content based on real-time cover position, optimizing the user experience without adding complex manual control mechanisms.

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.
