Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If electromagnetic wave emitters with antenna directivity are used to simulate ionizing radiation, then the system cost is reduced, but the measurement precision deteriorates due to inability to accurately simulate homogeneous omnidirectional radiation
Solution Approach 1:
The patent changes the fundamental parameter of radiation emission pattern from directional (antenna-based) to omnidirectional (isotropic equivalent). By calculating equivalent isotropic radiation values based on directional antenna measurements and applying correction factors, the system achieves accurate homogeneous simulation without requiring expensive omnidirectional antenna arrays, thus resolving the contradiction between cost and precision
Solution Approach 2:
The patent introduces an intermediary computational layer that processes directional antenna measurements and converts them into equivalent omnidirectional radiation values. This mathematical intermediary (calculation unit with correction algorithms) allows the system to use simple directional antennas while achieving the measurement accuracy of complex omnidirectional systems, resolving the cost-precision contradiction
2Measurement precision
If complex omnidirectional antenna systems are used to simulate homogeneous ionizing radiation, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The patent extracts the omnidirectional radiation simulation capability from the physical antenna structure and relocates it to the computational domain. Instead of using complex physical omnidirectional antenna systems, the invention uses simple directional antennas combined with mathematical correction algorithms, thereby reducing device complexity while maintaining measurement precision
Solution Approach 2:
The patent replaces the mechanical/physical complexity of omnidirectional antenna systems with computational algorithms. The calculation unit performs mathematical transformations on signals from simple directional antennas to produce equivalent omnidirectional radiation measurements, substituting physical complexity with computational simplicity
3Ease of operation
If simple electromagnetic wave emitters are used for simulation, then the ease of operation is improved, but the measurement precision deteriorates due to antenna directivity issues
Solution Approach 1:
The patent enables the simple directional antenna emitter to self-correct its inherent directivity limitation through built-in calculation units that automatically compute equivalent omnidirectional values. The system performs self-calibration and self-correction using pre-stored antenna radiation patterns, maintaining ease of operation while achieving high measurement precision without requiring complex manual adjustment
