Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a hyper block structure is implemented for device allocation in UWB networks, then network performance and accuracy are enhanced, but device complexity and protocol overhead increase
Solution Approach 1:
The hyper block structure segments the time domain into multiple ranging blocks, each allocated to specific devices. This segmentation allows for organized device allocation and ranging operations, improving accuracy while managing complexity through structured division of the communication resource space.
Solution Approach 2:
The patent introduces a hierarchical dimension to the time domain structure by creating hyper blocks that contain multiple ranging blocks. This dimensional expansion allows for more sophisticated device allocation and ranging accuracy improvement without linearly increasing overall system complexity.
2Measurement precision
If device allocation information is transmitted for each ranging block, then device allocation accuracy is improved, but transmission overhead and energy consumption increase
Solution Approach 1:
The patent merges device allocation information for multiple ranging blocks into a single hyper block structure. This consolidation reduces the number of separate transmissions needed, thereby lowering energy consumption while maintaining accurate device allocation through the comprehensive hyper block allocation information.
3Productivity
If multiple ranging blocks are allocated within a hyper block, then network throughput and productivity are improved, but device complexity and resource management difficulty increase
Solution Approach 1:
The hyper block structure segments the network resource space into multiple ranging blocks, each assignable to different devices. This segmentation enables parallel ranging operations and improves network throughput while managing resource allocation complexity through the organized hierarchical structure.
Solution Approach 2:
The hyper block structure serves multiple functions simultaneously: it organizes device allocation, manages time resources, enables parallel ranging operations, and provides a framework for both single-device and multi-device scenarios. This multi-functionality improves productivity without proportionally increasing management complexity.
