Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional antenna structures are used to transmit radio waves, then electromagnetic field transmission can be achieved, but the field strength decreases rapidly with distance due to radiation field characteristics
Solution Approach 1:
The patent changes the fundamental parameter of electromagnetic field propagation by transitioning from radiation fields to guided surface waves. The Zenneck waveguide probe structure modifies the field configuration to create a guided mode that travels along the Earth's surface, fundamentally altering how distance attenuation occurs compared to conventional free-space radiation.
Solution Approach 2:
The patent introduces the Earth's surface as an intermediary medium for electromagnetic wave propagation. By utilizing the ground as a guiding surface, the system creates a Zenneck surface wave that is confined to propagate along the terrestrial medium, effectively using the Earth as a waveguide to maintain field strength over distance.
2Length of stationary object
If Zenneck surface wave transmission is implemented, then field strength can be maintained over distance, but accurate measurement and analysis of transmission efficiency remains difficult
Solution Approach 1:
The patent segments the measurement system into distributed components: multiple metering devices positioned at different locations along the transmission path, a central controller that coordinates data collection, and a computing environment for analysis. This segmentation allows field strength to be measured at multiple points, enabling reconstruction of transmission characteristics over distance.
Solution Approach 2:
The patent implements feedback mechanisms through the central controller that receives measurements from distributed metering devices, processes this data in real-time, and provides feedback for analyzing transmission efficiency. The system continuously monitors field strength at multiple locations and uses this feedback to characterize the Zenneck wave propagation.
3Measurement precision
If multiple metering devices are deployed to measure field strength at different locations, then transmission efficiency can be assessed, but system complexity increases
Solution Approach 1:
The patent designs the metering devices with multi-functionality, where each device can measure multiple field parameters (electric field strength, magnetic field strength) and operate at different locations. The standardized design allows the same basic device type to be deployed throughout the network, reducing operational complexity while maintaining comprehensive measurement capability.
Solution Approach 2:
The patent merges the functionality of multiple distributed measurement points into a unified data processing system. The central controller aggregates data from all metering devices and integrates it with transmission parameters to calculate overall transmission efficiency, combining what would otherwise be separate analysis tasks into a single comprehensive assessment.
