Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless power transfer and wireless data communication are executed simultaneously using electromagnetic waves, then both functions can operate, but interference occurs between the two operations reducing efficiency and reliability
Solution Approach 1:
The patent segments the wireless resource usage by dividing time, frequency, and antenna resources into separate allocations for wireless power transfer and wireless data communication. The base station schedules these resources to prevent simultaneous usage that would cause interference, while still enabling both functions to operate within the same system.
Solution Approach 2:
The patent implements dynamic scheduling where the base station continuously allocates and reallocates wireless resources (time slots, frequency bands, antenna elements) based on current system conditions, traffic demands, and power transfer requirements. This dynamic resource management allows the system to adaptively prevent interference while maintaining both communication and power transfer capabilities.
2Reliability
If wireless resources are allocated to prevent interference between power transfer and data communication, then reliability improves, but system complexity increases due to scheduling requirements
Solution Approach 1:
The patent employs a unified base station that performs multiple functions including wireless data communication, wireless power transfer coordination, and resource scheduling. This multi-functional approach consolidates control in a single entity rather than requiring separate coordination mechanisms, thereby managing complexity while achieving reliable interference prevention.
Solution Approach 2:
The base station acts as an intermediary that mediates between wireless data communication requests and wireless power transfer operations. It receives scheduling requests from both communication devices and power receiving devices, then allocates resources to prevent interference, serving as a central coordinating entity that simplifies the overall system architecture.
3Area of stationary object
If multiple wireless terminal apparatuses and wireless power transmitters coexist in a LAN area, then network coverage increases, but interference between multiple power transfers and data communications occurs
Solution Approach 1:
The patent applies local quality by allowing different wireless resources to be allocated to different spatial locations, devices, or service types within the LAN area. The base station can assign specific time-frequency antenna resources to specific terminal devices or power transfer operations based on their local requirements, enabling multiple operations to coexist without mutual interference while expanding overall coverage.
