Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If base stations configure a large number of antennas for massive MIMO technology, then wireless charging capability is improved, but system complexity and resource management difficulty increase
Solution Approach 1:
The patent segments the wireless charging request handling by introducing specific message types (e.g., RRC Reconfiguration message with wireless charging configuration, RRC Release message with suspend configuration) that divide the charging process into distinct phases. This segmentation allows the base station to manage wireless charging functionality independently from communication functions, reducing system complexity while maintaining versatility.
Solution Approach 2:
The patent implements multi-functionality by enabling base stations to simultaneously perform communication and wireless charging functions using the same antenna resources. The core network can configure antennas for either communication or wireless charging based on service requirements, making the system universal and adaptable to different operational modes without increasing overall complexity.
2Measurement precision
If wireless charging requests are transmitted through the core network, then charging control accuracy is improved, but signaling overhead and network load increase
Solution Approach 1:
The patent applies preliminary action by having the core network pre-configure wireless charging parameters (such as power levels, antenna resources, and timing) before actual charging begins. This pre-configuration is transmitted through RRC Reconfiguration messages, allowing the base station to execute charging operations with high accuracy without requiring continuous real-time signaling, thereby reducing overall signaling overhead.
Solution Approach 2:
The patent introduces the RRC layer as an intermediary between the core network and the physical charging process. The core network sends high-level charging instructions through RRC messages, which then translate these into specific base station actions. This intermediary approach maintains charging control accuracy while reducing the need for direct, detailed signaling between the core network and charging components.
3Productivity
If wireless charging is performed during communication operations, then resource utilization is improved, but interference between charging and communication signals increases
Solution Approach 1:
The patent implements periodic action by alternating between communication and wireless charging operations in time-division multiplexed fashion. The base station configures specific time periods for each function, switching between them based on service requirements. This periodic switching allows both communication and charging to occur with high resource utilization while minimizing mutual interference through temporal separation.
Solution Approach 2:
The patent applies local quality by assigning different spatial and frequency resources to communication and wireless charging functions within the base station. Specific antenna elements or beam directions are dedicated to one function while others serve the other function, creating localized quality differences that reduce interference. This allows simultaneous operation in different spatial domains with minimal mutual interference.
4Productivity
If wireless charging configuration is dynamically adjusted based on terminal conditions, then charging efficiency is improved, but processing complexity and response time requirements increase
Solution Approach 1:
The patent implements feedback mechanisms where the terminal reports its charging status, power needs, and environmental conditions back to the base station and core network. Based on this feedback, the system dynamically adjusts charging parameters through RRC Reconfiguration messages. This feedback loop enables high charging efficiency while distributing processing complexity across multiple network elements rather than concentrating it in one location.
Solution Approach 2:
The patent introduces dynamics by enabling real-time adjustment of wireless charging configurations based on changing terminal conditions. The RRC protocol allows dynamic reconfiguration of charging parameters such as power levels, antenna resources, and timing without requiring system reconfiguration. This dynamic capability improves charging efficiency while managing processing complexity through standardized protocol-based adjustments.
