Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IoT systems face challenges in easily setting and controlling multiple home appliances due to difficulties in identifying their positions and managing remote control access, leading to user inconvenience.
Innovation Solution
A display device with a wireless communication interface, controller, and display that generates a home map showing appliance positions, supports do-not-disturb modes, and uses ultra-wideband communication for precise positioning and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually set and change names and types of home appliances, then control functionality is achieved, but it becomes difficult to identify appliance positions and requires repeated manual updates when positions change
Solution Approach 1:
The system enables appliances to automatically register their positions and update control information without manual user input. The localization unit automatically determines appliance positions, and the control information generation unit automatically creates and updates control information based on detected positions, eliminating the need for users to manually set and update appliance details.
Solution Approach 2:
The system performs preliminary localization and control information generation before user control operations. By pre-establishing the relationship between appliance positions and control information, the system prepares the control framework in advance, so when users want to control appliances, the correct control information is already available without requiring manual setup at that moment.
2Adaptability or versatility
If multiple users can remotely control appliances in a space, then accessibility is improved, but users experiencing the space face inconvenience from unauthorized control
Solution Approach 1:
The system applies different control permissions to different spatial locations. When a user terminal is detected in a specific space, the system generates control information that allows control of appliances in that space. This creates location-based access control where control rights are tied to physical presence rather than universal remote access, preventing unauthorized control while maintaining accessibility for legitimate users.
Solution Approach 2:
The system introduces a localization unit and control information generation unit as intermediaries between user terminals and appliances. These intermediary components verify the spatial relationship and generate appropriate control information, acting as a mediator that grants or denies control access based on location rather than allowing direct universal access.

AI summary
A display device according to an embodiment of the present invention comprises: a wireless communication interface which transmits and receives signals to and from at least one peripheral device; a controller which acquires location information of the peripheral device; and a display which displays a home map in which the peripheral device is arranged in a plan view on the basis of the location information of the peripheral device. Upon receiving a control command for the at least one peripheral device displayed on the home map, the controller transmits a control signal to the peripheral device so that the peripheral device operates according to the control command.
