Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If devices are registered in IoT-related applications to use IoT technology, then device control functionality is achieved, but the registration process becomes cumbersome and complex
Solution Approach 1:
The system enables automatic device registration through UWB-based proximity detection. When a remote control approaches a target device, the system automatically identifies and registers the device without requiring manual user registration in IoT applications, making the process self-service and eliminating complexity
Solution Approach 2:
The patent replaces the manual registration mechanism (user interaction with IoT applications) with an automated UWB-based detection system. The UWB anchors and sensors automatically detect device proximity and orientation, substituting the complex software registration process with a simple physical approach action
2Measurement precision
If precise positioning is implemented to identify device locations, then control accuracy is improved, but the system complexity and measurement requirements increase
Solution Approach 1:
The positioning system is segmented into multiple UWB anchors distributed in the environment. Each anchor independently measures distance to the remote control, and the system combines these segmented measurements to calculate precise 3D position through triangulation, achieving high accuracy without requiring a single complex positioning system
Solution Approach 2:
UWB anchors serve as intermediary elements between the remote control and the positioning system. These anchors facilitate precise measurement by acting as reference points for time-of-flight distance calculations, enabling accurate positioning without direct complex interaction between the remote control and central processing
3Measurement precision
If multiple UWB anchors are deployed to determine relative coordinates, then positioning accuracy is improved, but the system configuration becomes more complex
Solution Approach 1:
The UWB anchors are designed with multi-functionality, serving both as positioning reference points and as orientation detection aids. The same anchors used for distance measurement also provide angular information through their spatial arrangement, eliminating the need for separate orientation sensors and simplifying system configuration

AI summary
A remote control system may include a display device including a first ultra wideband (UWB) anchor that uses UWB communications, a second UWB anchor that uses UWB communications and is spaced apart from the firstUWB anchor by a specified distance or more, and a remote control. The remote control system may be configured to select a control target device and control it by identifying the relative coordinates of the remote control using UWB communications, and identify the orientation direction of the remote control using a 9-axis sensor value.
