Management device, display switch system, and air-conditioning system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing management devices for apparatuses, such as air-conditioning systems, require complex operations for users to change language or text size settings, especially when unfamiliar languages are used, and struggle to adapt to user preferences, leading to difficulty in use, particularly for elderly users or in multi-national settings.
Innovation Solution
A management device connected to an apparatus with a display unit, wireless communication unit, and control unit that adjusts display settings based on a mobile terminal's settings when in close proximity, automatically adapting to user preferences by wirelessly communicating with a mobile terminal to change language and text size settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If display settings are manually changed by users consulting instruction manuals, then language and text size settings can be adjusted, but the operation becomes complicated and time-consuming
Solution Approach 1:
The management device automatically detects the mobile terminal's display settings (language, text size) and adjusts its own display settings accordingly without requiring manual user input. The control unit receives setting information from the mobile terminal via wireless communication and automatically configures the display unit, enabling the system to serve itself rather than requiring user configuration
Solution Approach 2:
The mobile terminal stores display setting information in advance, and when the management device detects the mobile terminal, it automatically retrieves and applies these pre-stored settings. This preliminary preparation of setting data eliminates the need for users to manually configure settings at the moment of use
2Adaptability or versatility
If unfamiliar languages are used as default languages, then multi-national settings are supported, but changing display settings becomes further difficult
Solution Approach 1:
The system automatically detects the mobile terminal's language setting and adjusts the management device's display language accordingly, eliminating the need for users to manually navigate through unfamiliar language menus to change settings. The control unit automatically configures the display based on the detected mobile terminal settings
3Productivity
If text size is reduced to display more information on one screen, then miscellaneous settings can be performed, but text becomes hard to read for elderly users
Solution Approach 1:
The system applies different text sizes to different display contexts based on the mobile terminal's settings. When the mobile terminal indicates a preference for larger text, the management device adjusts its display unit to show larger text, making it readable for elderly users while still allowing access to all necessary functions and settings
Solution Approach 2:
The display settings of the management device are made dynamic and adjustable based on the detected mobile terminal settings. The control unit automatically changes text size, language, and other display parameters according to the mobile terminal's configuration, allowing the display to adapt to different user needs rather than maintaining a fixed small text size

AI summary
A management device is connected to an apparatus and is configured to manage the apparatus. The management device includes a display unit, a wireless communication unit, and a control unit. The display unit is configured to display information about the apparatus. The wireless communication unit is configured to wirelessly communicate with a mobile terminal. The control unit is configured to, when a distance between the management device and the mobile terminal is shorter than a threshold, adjust display settings of the display unit to display settings of the mobile terminal.
