Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If complex setups with moveable test antennas and complicated measuring hardware are used, then measurement precision is improved, but device complexity increases and ease of operation deteriorates
Solution Approach 1:
The patent replaces the mechanical moveable test antenna system with a fixed array of radar receivers that directly detect and visualize the beam pattern through LED indicators. This substitution eliminates the need for complex mechanical positioning while maintaining measurement capability through the array geometry itself providing spatial information.
Solution Approach 2:
The patent creates a visual copy of the electromagnetic beam pattern by using LED indicators that directly represent the presence and intensity of radar signals at different spatial positions. This visual copying allows operators to interpret beam patterns intuitively without requiring complex data processing or specialized knowledge.
2Measurement precision
If complex setups with moveable test antennas are used, then measurement precision is improved, but ease of operation deteriorates due to requiring highly skilled personnel
Solution Approach 1:
The patent uses color-changing LED indicators to represent different signal intensities and beam pattern characteristics. This visual encoding allows operators to quickly interpret measurement results without requiring specialized knowledge of radar signal processing, thereby reducing the skill level needed while maintaining measurement accuracy.
Solution Approach 2:
The visual copy of the beam pattern created by the LED array provides an intuitive representation that can be directly interpreted by operators. This eliminates the need for trained personnel to analyze complex raw data or operate sophisticated equipment, as the measurement results are immediately visible and interpretable.
3Ease of operation
If fixed radar receiver arrays are used instead of moveable antennas, then ease of operation is improved, but measurement precision may deteriorate
Solution Approach 1:
The patent uses a two-dimensional array of receivers to capture spatial information, transforming the measurement from a single-point temporal measurement (moveable antenna) to a distributed spatial measurement. This dimensional change allows the fixed array to achieve equivalent measurement capability without requiring mechanical movement, maintaining precision while improving ease of operation.
