Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If sequential search and communication are performed, then system complexity is reduced, but latency increases and productivity decreases
Solution Approach 1:
The system performs preliminary actions by initiating the search channel to find alternative base stations before the current base station connection fails or before optimization is needed. This allows the search process to be completed in advance, reducing latency when handover is actually required while maintaining high data transmission speeds during normal operation.
Solution Approach 2:
The patent introduces a parallel dimension by operating both the communication channel (for data transmission) and search channel (for base station discovery) simultaneously. This dimensional separation allows search and communication functions to execute in parallel rather than sequentially, eliminating the trade-off between search completeness and transmission speed.
2Reliability
If all RF chains are used for communication, then communication reliability is improved, but device complexity and resource consumption increase
Solution Approach 1:
The system segments the RF chain functionality by dedicating specific RF chains to communication tasks and others to search tasks. This segmentation allows the communication channel to maintain high reliability through dedicated resources while the search channel independently explores alternative base stations, avoiding the need to allocate all RF chains to communication and reducing overall device complexity.
Solution Approach 2:
The search channel is designed as a multi-functional component that can operate independently of the communication channel. It serves multiple purposes: discovering alternative base stations, measuring signal quality, and preparing handover parameters. This universality allows the system to maintain communication reliability without requiring all RF chains to be dedicated to communication, thereby reducing device complexity.
3Adaptability or versatility
If base station search is performed during data transmission, then network adaptability is improved, but computational complexity increases
Solution Approach 1:
The search channel performs preliminary actions to identify and evaluate alternative base stations during normal data transmission. By conducting this search in advance rather than reactively when problems arise, the system improves network adaptability while the computational burden is distributed over time rather than concentrated during critical transmission moments, effectively managing computational complexity.
Solution Approach 2:
The patent resolves the computational complexity issue by creating a separate dimensional space for search operations. The search channel operates as an independent dimension that can process search queries and evaluate base stations simultaneously with data transmission, rather than sharing the same computational resources. This dimensional separation allows network adaptability to be improved without proportionally increasing computational complexity during active transmission.
