Engineering Contradiction Analysis
1Loss of energy
If higher transmission power is used to compensate for low transmission efficiency in wireless energy charge, then energy transmission efficiency is improved, but device complexity and control difficulty increase
Solution Approach 1:
The base station performs beamforming control procedures in advance to establish optimal beams for wireless energy charge before actual energy transmission begins. This preliminary beam establishment simplifies the control procedure during energy transmission by avoiding real-time complex adjustments.
Solution Approach 2:
The patent introduces beamforming as an intermediary technique between the base station and terminal for wireless energy charge. The beamforming mechanism mediates the energy transmission process, enabling efficient energy delivery without requiring direct complex control between the energy charging device and terminal.
2Productivity
If beamforming is applied to wireless energy charge, then transmission efficiency is improved, but control procedure details become more complex
Solution Approach 1:
The beamforming control procedure is segmented into distinct phases: beam indication from base station to terminal, beam determination by terminal, and beam application for energy reception. This segmentation simplifies the overall control complexity by breaking down the beamforming process into manageable, sequential steps.
Solution Approach 2:
The base station provides beam indications to the terminal, and the terminal determines and applies reception beams based on these indications. This feedback mechanism ensures that the beamforming control is coordinated and optimized for wireless energy charge while maintaining manageable complexity through structured information exchange.
