Dual-Display Relay Meter Layout for Mounting-Independent Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Relays with integrated meter and protection functions face challenges in visibility and user convenience due to the complexity of displaying multiple functions on a single screen, limiting efficiency and effectiveness in power system management.
Innovation Solution
The use of two separate displays, one rectangular and horizontal, and the other rectangular and vertical, configured orthogonally within the same housing, allowing for independent display of meter and relay functions regardless of the device's mounting direction, enhancing visibility and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single LCD screen is used to display both meter function information and relay function information, then the device complexity is reduced, but the visibility and user convenience deteriorate due to the complexity of displaying multiple functions simultaneously
Solution Approach 1:
The display system is segmented into multiple independent screens, where each screen is dedicated to displaying specific function information (meter function on one screen, relay function on another). This segmentation eliminates the complexity of displaying multiple functions on a single screen while improving visibility and user convenience by allowing users to view relevant information on dedicated displays.
2Device complexity
If a single LCD screen is used to display both meter and relay functions, then the device structure is simplified, but the information visibility is reduced
Solution Approach 1:
The display structure is segmented into multiple screens, with each screen optimized for displaying specific types of information. This allows all necessary information to be displayed simultaneously with high visibility, as each screen can be dedicated to a specific function without competing for space with other functions.
3Ease of operation
If two or more displays are used to display meter and relay function information separately, then the visibility and convenience are improved, but the device complexity increases
Solution Approach 1:
The device uses multiple displays that are independently configured for specific functions, eliminating the need for complex software control to manage a single multi-functional screen. Each display operates independently, simplifying the overall system control while maintaining high user convenience.
4Ease of manufacture
If a single screen displays both meter and relay functions, then the manufacturing cost is reduced, but the operational efficiency deteriorates
Solution Approach 1:
By using multiple dedicated displays instead of a single multi-functional screen, the system improves operational efficiency through enhanced visibility and easier information access. The increased manufacturing cost is offset by the significant improvement in operational efficiency and user convenience.

AI summary
An electric device having multiple displays, and a control method therefor are proposed. The electric device is mounted on a supporting body, and includes a first display (10) and a second display (20), which are configured in a same housing (30) and are facing a front, wherein one of the first display (10) and the second display (20) provides a rectangular horizontal screen and displays information about a meter function, and the other of the first display (10) and the second display (20) provides a rectangular vertical screen and displays information about a relay function.
