Engineering Contradiction Analysis
1Reliability
If radio frequency couplers in the form of transmission lines terminated with matched loads are used, then wireless encoders can transmit signals, but the electromagnetic fields are not well contained and are strongly affected by the propagation environment, leading to inefficient encoding
Solution Approach 1:
A shielded enclosure acts as an intermediary structure between the radio frequency coupler and the external environment. The enclosure contains the electromagnetic fields generated by the coupler, preventing them from being affected by external propagation conditions while still allowing controlled interaction with wireless communication devices through designated apertures.
Solution Approach 2:
The shielded enclosure creates an electromagnetically controlled internal environment that isolates the radio frequency coupler from external interference. This inert electromagnetic atmosphere ensures stable field containment regardless of external propagation conditions, metal parts, or device form factors.
2Measurement precision
If a short-range, less powerful antenna is used to encode only the nearest wireless communication device, then individual encoding is achieved, but encoding efficiency and coverage are reduced
Solution Approach 1:
The shielded enclosure with selective apertures creates localized electromagnetic field regions that can be precisely directed at specific wireless communication devices. This allows the system to maintain individual device encoding precision while potentially encoding multiple devices in sequence or parallel through different aperture configurations.
Solution Approach 2:
The system can dynamically adjust which apertures are active or how the shielded enclosure is configured to adapt to different encoding scenarios. This dynamic control allows optimization between individual device precision and overall encoding throughput based on real-time requirements.
