Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If scheduling information is transmitted using existing UWB network methods, then device communication can be maintained, but transmission efficiency and resource allocation optimization are insufficient
Solution Approach 1:
The scheduling information is segmented into multiple information elements (IEs), each serving specific functions. The first IE carries block structure configuration information while the second IE carries scheduling information for specific devices or device groups. This segmentation allows efficient processing and reduces overall complexity by organizing data into manageable, purpose-specific units.
Solution Approach 2:
The patent introduces a hierarchical dimension to scheduling information transmission by organizing data across multiple IEs with different levels of abstraction. The first IE provides structural context while the second IE provides device-specific scheduling details, creating a multi-layered information architecture that improves transmission efficiency without proportionally increasing complexity.
2Productivity
If address indexing is not defined in UWB networks, then device identification can be simplified, but resource allocation and device management become inefficient
Solution Approach 1:
The patent introduces an address indexing mechanism that acts as an intermediary between device identifiers and resource allocation. The indexing system maps device addresses to scheduling information, enabling efficient resource allocation without requiring complex direct mapping between all devices and all resources. This intermediary layer simplifies the overall system while improving allocation efficiency.
3Loss of information
If comprehensive scheduling information is transmitted to all devices, then complete information availability is achieved, but transmission overhead and processing load increase
Solution Approach 1:
The scheduling information is tailored to local needs of specific devices or device groups rather than providing universal information to all devices. The second IE contains scheduling information targeted at specific devices or groups, reducing transmission overhead while ensuring each device receives the complete information it needs for its specific operations.
Solution Approach 2:
By segmenting scheduling information into device-specific or group-specific IEs, the system transmits only necessary information to each device. This segmentation prevents unnecessary transmission overhead and processing load on devices that do not need certain scheduling information, while maintaining complete information availability for devices that do need it.
