Engineering Contradiction Analysis
1Productivity
If multiple antenna modules are used to enable transmission and reception of wireless signals in various frequency bands and wireless power transmission and reception, then data transfer rate and wireless power transfer rate are improved, but device size increases and space for antenna modules is limited
Solution Approach 1:
The patent combines multiple antenna modules into a single integrated structure that can operate across multiple frequency bands. The antenna device includes multiple antenna elements arranged in a compact configuration that enables both communication signals and power transfer signals to be transmitted and received simultaneously or sequentially, thereby improving data transfer rates without proportionally increasing device size.
Solution Approach 2:
The antenna device is designed to perform multiple functions: transmitting and receiving communication signals in various frequency bands, wireless power transmission and reception, and potentially sensing functions. This multi-functionality allows a single antenna module to replace what would traditionally require multiple separate modules, optimizing space utilization while maintaining high data transfer capabilities.
2Power
If multiple antenna modules are used to enable transmission and reception of wireless signals in various frequency bands, then wireless power transfer rate is improved, but space for antenna modules is restricted
Solution Approach 1:
The antenna elements are arranged in a nested or layered configuration where smaller antenna structures are positioned within or between larger ones. This nesting approach allows multiple antenna modules to be packed into a smaller overall footprint, enabling high wireless power transfer rates without requiring proportionally more space.
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement of antenna elements rather than simple planar expansion. By arranging antenna modules in multiple layers or dimensions, the design achieves high wireless power transfer capability while constraining the two-dimensional footprint, effectively transitioning from area-based to volume-based optimization.
3Reliability
If discrete elements are disposed on the coil and connected through via, then signal processing is optimized and voltage separation is achieved, but device complexity increases
Solution Approach 1:
The antenna device separates different voltage domains and signal processing functions by placing discrete passive elements (capacitors, inductors, resistors) at specific locations on the coil structure. Each element handles a specific function such as voltage separation, signal filtering, or impedance matching, which improves overall signal processing reliability while allowing modular optimization of each segment.
Solution Approach 2:
Passive elements are introduced as intermediary components between the coil and active circuits. These discrete elements mediate signal transitions, provide voltage isolation, and enable efficient power transfer without requiring complex active circuitry, thereby improving reliability while keeping the overall device complexity manageable through the use of simple passive components.
