Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If transmission power is increased to compensate for low transmission efficiency in wireless energy charge, then energy charge effectiveness is improved, but interference to coexisting wireless communication systems occurs
Solution Approach 1:
The patent segments the resource allocation into distinct communication resources and energy charge resources. The base station allocates specific time-frequency resources for energy charge transmission separate from communication resources, allowing high-power energy transmission without interfering with communication signals. This segmentation resolves the contradiction by enabling effective energy charge while protecting communication systems through resource isolation.
Solution Approach 2:
The patent implements periodic time-division multiplexing where energy charge transmission occurs in dedicated time slots alternating with communication time slots. During energy charge periods, high transmission power is used for efficient energy transfer, while during communication periods, normal communication operations resume without interference. This periodic action allows the system to achieve both high energy charge effectiveness and maintain communication quality.
2Adaptability or versatility
If wireless energy charge is performed without clear scheduling procedures, then energy charge functionality is achieved, but scheduling control and system coordination become unclear
Solution Approach 1:
The patent extends existing universal wireless communication scheduling mechanisms to also manage energy charge operations. The base station uses the same resource allocation framework, signaling protocols, and coordination procedures for both communication and energy charge. This multi-functionality approach enables energy charge functionality while maintaining clear, standardized scheduling control without increasing system complexity.
Solution Approach 2:
The base station acts as an intermediary that coordinates between communication users and energy charge receivers. It receives energy charge requests, allocates appropriate resources, and manages the scheduling of energy charge transmissions. This intermediary role provides clear scheduling control and system coordination, resolving the ambiguity that would otherwise exist in uncoordinated energy charge operations.
3Loss of energy
If high transmission power is used for wireless energy charge, then energy charge efficiency is improved, but the impact on human body and radio wave interference increase
Solution Approach 1:
The patent applies local quality by concentrating high transmission power only in the specific spatial region and time slots where energy charge is required, rather than broadcasting high power universally. The base station directs energy charge transmissions to specific receivers using beamforming or directional antennas, limiting the spatial footprint of high-power radiation. This reduces overall interference and human body exposure while maintaining high energy charge efficiency at the target location.
