Device control system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing device control systems face challenges in efficiently displaying necessary information on remote controls, leading to overcrowding and legibility issues when the number of information pieces increases, as they present communication and target information together without separation.
Innovation Solution
A device control system that includes a wireless device, a handheld operation terminal, and a wireless operation terminal, allowing selective transmission of only necessary information to the display unit based on the situation, using a wireless LAN router and an external connector to manage communication modes and reduce information overload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If registration information is displayed on the remote control, then the device can be connected to the network, but the display space is insufficient and text becomes illegible when multiple information items are shown together
Solution Approach 1:
The patent segments registration information into two distinct types: communication information (for connecting the remote control to the mobile terminal) and target information (for specifying the air conditioner). These segmented information types are then displayed on separate displays - the first display shows communication information, while the second display shows target information. This segmentation resolves the contradiction by providing dedicated space for each information type, ensuring both connection reliability and display legibility.
2Loss of information
If all registration information is presented together on one display, then complete information is provided, but the display space decreases and text becomes smaller
Solution Approach 1:
The patent transitions from a single-dimension display approach to a multi-dimensional display architecture by introducing multiple displays (first display and second display) arranged in different spatial dimensions. Communication information is presented on the first display while target information is presented on the second display, effectively utilizing dimensional separation to maintain information completeness while preserving adequate display area and text legibility for each information type.

AI summary
A device control system includes: a wireless device including a device to be controlled and external connector that is connected to the device to be controlled, transmits/receives information to/from the device to be controlled, and is wirelessly connected to a wireless LAN router; a handheld operation terminal that includes a display unit for displaying information and operates the device to be controlled; and a wireless operation terminal that is a terminal different from the handheld operation terminal and operates the device to be controlled via the external connector. When the wireless device receives, from the handheld operation terminal, an information acquisition request for first information that is information necessary for connecting the wireless operation terminal to the external connector, the wireless device selectively transmits the first information to the handheld operation terminal, and the display unit displays the first information.
