Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If millimeter wave band is used in SL transmission system to improve transmission rate, then transmission speed is improved, but resource selection complexity increases
Solution Approach 1:
The patent changes the parameter of transmission frequency to millimeter wave band to achieve higher transmission rates. This parameter change enables faster data transmission but simultaneously increases the complexity of resource selection due to the specific characteristics of millimeter wave propagation and beamforming requirements.
2Reliability
If spatial domain transmission filters are used to optimize resource allocation, then transmission reliability is improved, but device complexity increases
Solution Approach 1:
The patent applies spatial domain transmission filters (beamforming) in advance to pre-optimize the transmission resources. By determining resources based on spatial domain characteristics before actual data transmission, the system improves transmission reliability while managing device complexity through preliminary resource configuration.
Solution Approach 2:
The patent applies spatial domain transmission filters to create direction-specific transmission paths. Different spatial regions are assigned different transmission characteristics and resources, improving reliability for specific directional communications while maintaining manageable device complexity through localized optimization.
3Productivity
If transmission resources are allocated by base station, then resource allocation efficiency is improved, but transmission delay increases
Solution Approach 1:
The patent enables terminal devices to autonomously determine their own transmission resources based on spatial domain transmission filter characteristics. This self-service approach eliminates the need for base station allocation, improving transmission speed while reducing transmission delay by allowing terminals to immediately select appropriate resources without waiting for network coordination.
