Engineering Contradiction Analysis
1Measurement precision
If UWB network configuration is used for positioning, then positioning accuracy is improved, but communication range is limited by typical UWB limits
Solution Approach 1:
The patent combines multiple UWB networks into a mesh network structure, where multiple user terminals act as relays to extend the communication range. By merging individual UWB networks that would otherwise be limited in range, the system achieves both accurate positioning within each network segment and extended overall coverage through the interconnected mesh structure.
Solution Approach 2:
The patent transitions from a single-point UWB communication model to a multi-dimensional mesh network structure. By adding spatial dimensions to the network topology (multiple nodes connected in a mesh pattern), the system extends communication range beyond typical UWB limits while maintaining positioning accuracy through the distributed nature of the mesh architecture.
2Area of stationary object
If multiple UWB networks are connected for multi-user interaction, then communication coverage is expanded, but network complexity increases
Solution Approach 1:
The patent segments the overall positioning and communication system into multiple independent but interconnected UWB network segments. Each segment operates autonomously with its own user terminals and objects, reducing the complexity burden on any single node while collectively achieving expanded communication coverage through the segmented mesh architecture.
Solution Approach 2:
The patent implements a universal mesh network protocol that enables user terminals to perform multiple functions: acting as endpoints for positioning, serving as relays for extending coverage, and functioning as intermediate nodes for multi-user interaction. This multi-functionality reduces overall system complexity by using standardized protocols across all nodes rather than requiring specialized configurations for each function.
3Ease of operation
If graph settings are used to configure UWB networks, then network management becomes systematic, but configuration complexity increases
Solution Approach 1:
The patent implements automatic graph-based network configuration where user terminals autonomously discover each other, generate appropriate graph structures, and establish connections without manual intervention. The system self-configures the mesh network topology based on detected UWB signals and spatial relationships, making network management systematic through automated graph algorithms while reducing configuration complexity for end users.
Solution Approach 2:
The patent uses feedback mechanisms where user terminals continuously monitor UWB signal strength, position information, and network connectivity status to dynamically adjust graph configurations. This feedback loop enables the system to automatically optimize network management parameters and reconfigure the graph structure in response to changing environmental conditions, making the system adaptable without increasing user configuration burden.

AI summary
An operating method of a user terminal, the operating method includes: configuring a first ultra-wide band (UWB) network corresponding to a target user based on first objects including the user terminal dependent on the target user, a UWB communication module including any one or any combination of any two or more of a UWB sensor, a UWB antenna, and a UWB tag; searching for a second UWB network corresponding to a multi-user adjacent to the first UWB network; obtaining, based on a result of the searching, relative position information between the target user and the multi-user by connecting the first UWB network to the second UWB network; and performing, based on the relative position information, interaction and information sharing between the target user and the multi-user.
