Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless power transfer and wireless data communication are processed simultaneously, then user convenience is improved, but interference between the two services occurs
Solution Approach 1:
The patent segments the wireless resource allocation into separate control and data portions. The base station divides time-frequency resources into control regions (for power transfer coordination) and data regions (for communication), allowing simultaneous operation while preventing interference through spatial and temporal separation of the two services
Solution Approach 2:
The base station acts as an intermediary that coordinates between the wireless terminal apparatus and power transmitter. It manages resource allocation, schedules power transfer and data communication separately, and prevents direct interference by controlling the timing and frequency resources of both services
2Adaptability or versatility
If multiple wireless terminal apparatuses and power transmitters coexist in a LAN area, then system versatility is improved, but interference between multiple power transfers and data communications occurs
Solution Approach 1:
The patent introduces additional dimensions for resource allocation beyond simple time division. It uses frequency division, spatial division (different beams/antennas), and power level differentiation to allow multiple power transfer operations and data communications to coexist in the same time period without interfering with each other
Solution Approach 2:
The system dynamically adjusts resource allocation based on real-time conditions. The base station continuously monitors the state of multiple terminal apparatuses and power transmitters, and adaptively reconfigures time-frequency-power resources to optimize coexistence and prevent interference as devices are added or removed from the network
3Use of energy by moving object
If electromagnetic waves are used for both power transfer and data communication, then energy efficiency is improved, but frequency interference occurs
Solution Approach 1:
The patent assigns different frequency characteristics and power levels to different spatial locations and service types. Power transfer uses specific frequency bands with higher power in designated regions, while data communication uses other frequency bands or time slots, creating local quality differentiation that prevents frequency interference while maintaining energy efficiency
