Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single loop antenna is used for wireless communication, then the device structure is simple, but magnetic flux may not pass through the antenna effectively leading to poor communication
Solution Approach 1:
The patent divides the single loop antenna into two separate loop antennas (first loop antenna and second loop antenna) arranged at different orientations. This segmentation allows each antenna to capture magnetic flux from different directions, ensuring that at least one antenna can effectively receive the magnetic field regardless of the relative orientation between devices, thereby solving the communication reliability issue while maintaining relatively simple device structure
Solution Approach 2:
The patent implements a nested antenna configuration where the first and second loop antennas are positioned within the same device housing, with one antenna potentially placed above or below the other at different vertical levels. This nesting approach allows both antennas to coexist in a compact space, enabling effective magnetic flux capture from different orientations without significantly increasing the overall device footprint or complexity
2Reliability
If loop antennas are arranged to capture magnetic flux from different orientations, then wireless communication reliability is improved, but the device structure becomes more complex
Solution Approach 1:
The patent resolves the complexity issue by arranging the two loop antennas along the vertical dimension (z-axis) rather than spreading them horizontally. The first loop antenna is positioned at a first vertical level while the second loop antenna is positioned at a second vertical level, creating a multi-layered antenna structure. This vertical stacking approach enables both antennas to capture magnetic flux from different orientations while maintaining a compact horizontal footprint, thus improving communication reliability without proportionally increasing device complexity
Solution Approach 2:
Both loop antennas are designed with identical structural characteristics and are connected to the same controller, creating a universal antenna system where either antenna can perform the wireless communication function independently. This multi-functionality reduces the need for complex differential processing between antennas, as the system can switch between or combine signals from either antenna based on which one is effectively receiving magnetic flux, thereby managing complexity while maintaining reliability
3Area of stationary object
If a single loop antenna is used, then the device occupies less space, but the communication range is limited due to orientation constraints
Solution Approach 1:
By stacking the two loop antennas vertically at different height levels within the same device footprint, the patent extends the effective communication range in three-dimensional space. The vertical separation allows the antennas to capture magnetic flux from different spatial perspectives, enabling the device to maintain wireless communication over greater distances and with devices oriented at various angles, all while occupying the same horizontal area as a single-antenna device would
