Mobile Display Layout for Air Conditioner Test Operation Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack the ability to effectively display operating information necessary for assessing the test operation status of air conditioners, requiring servicemen to have extensive knowledge and experience, and existing dedicated devices are costly and labor-intensive to install.
Innovation Solution
A display device and application program that utilize a mobile terminal to display operating information of air conditioners, with a control unit arranging time information horizontally and first and second operating information display areas vertically, allowing for easy comparison and understanding of operating statuses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a centralized control system with dedicated devices is used to obtain and display air conditioner operating information, then the information can be collected from multiple units, but the device complexity and installation cost increase significantly
Solution Approach 1:
The patent applies universality by enabling a general-purpose mobile terminal to perform multiple functions: it acts as both the display device and the information collection device. The mobile terminal's existing communication capabilities are utilized to connect to air conditioners and retrieve operating information, eliminating the need for dedicated display devices and reducing system complexity while maintaining comprehensive information collection from multiple air conditioner units
Solution Approach 2:
The patent applies copying by using the mobile terminal's display screen to present copied representations of the air conditioner's operating information. The actual operating data from the air conditioner is replicated and displayed on the mobile device, allowing servicemen to view comprehensive operating information without requiring physical presence at each air conditioner unit or complex dedicated display hardware
2Loss of information
If dedicated display devices are installed to show operating information, then the information is always available, but the installation cost and labor increase
Solution Approach 1:
The patent applies self-service by leveraging the mobile terminal's existing hardware and software capabilities to perform the information display function. The mobile terminal already possesses a display screen, communication interfaces, and processing capabilities, so no additional dedicated display device needs to be manufactured or installed. The serviceman uses their own mobile device to access and display operating information, eliminating installation costs and labor while ensuring continuous information availability
3Measurement precision
If comprehensive operating information is displayed in detail, then the assessment accuracy improves, but the ease of understanding decreases due to information overload
Solution Approach 1:
The patent applies segmentation by dividing the comprehensive operating information into distinct functional categories or groups that can be selectively displayed. The mobile terminal interface can organize information such as temperature data, operational status, error codes, and performance metrics into separate sections, allowing servicemen to access detailed information when needed while maintaining an overview display for quick assessment. This segmented presentation maintains assessment accuracy by preserving all necessary data while improving ease of understanding through organized, hierarchical display structures
Data Source
AI summary
The present invention is intended to provide a general-purpose display device that is able to display on a display unit easily operating information required for assessing a test operation state, and an application program to be executed by the display device. Accordingly, in this display device which displays on the display unit the operating information of an air conditioner in which an outdoor unit provided with an outdoor heat exchanger and an indoor unit provided with an indoor heat exchanger are connected by a refrigerant pipe and a refrigerant is circulated by a compressor, a control unit of the display device controls the display unit so that time information is displayed horizontally and a first operating information display area and a second operating information display area for displaying first operating information and second operating information, respectively, corresponding to the time information are displayed vertically side by side.
