Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the package size is reduced to achieve higher integration density, then the device size is minimized, but the functionality and performance are limited
Solution Approach 1:
The waveguide structure incorporates adjustable slots that can dynamically change their geometric profiles (width, length, position) to modify electromagnetic wave characteristics. This dynamic adjustability allows a compact waveguide package to support multiple frequency bands and radiation patterns, effectively increasing functionality without increasing package size. The circuit controls the slot configurations to adapt to different operational requirements.
Solution Approach 2:
The invention changes physical parameters of the waveguide slots (geometric profile, position, size) to control electromagnetic wave frequency and radiation direction. By adjusting these parameters, the same compact waveguide structure can operate across different frequency bands and provide varied radiation patterns, resolving the contradiction between small size and multifunctionality.
2Measurement precision
If the geometric profile of apertures is adjusted to control electromagnetic wave frequency, then the frequency control precision is improved, but the device complexity increases
Solution Approach 1:
The waveguide structure serves multiple functions: it guides electromagnetic waves, radiates signals through adjustable slots, and provides frequency control through geometric profile adjustment. The same slot structure that controls frequency also affects radiation pattern and impedance, reducing the need for separate components and minimizing overall device complexity while maintaining precise frequency control.
Solution Approach 2:
The circuit adjusts the geometric parameters of the slots (width, length, position) to precisely control the resonant frequency and electromagnetic wave characteristics. This parameter adjustment mechanism provides accurate frequency control without requiring complex additional components, as the same structural elements are simply reconfigured.
3Measurement precision
If the distance between slots is adjusted to control radiation direction, then the beam steering precision is improved, but the mechanical complexity increases
Solution Approach 1:
The waveguide incorporates adjustable slots that can dynamically change their positions and configurations under circuit control. This dynamic adjustability enables precise beam steering and radiation pattern control without requiring complex mechanical assemblies. The slots can be repositioned or reconfigured electrically to achieve different radiation directions and patterns.
Solution Approach 2:
The invention replaces complex mechanical adjustment mechanisms with electrical control of the slot configurations. The circuit controls the geometric profiles and positions of the slots to achieve precise radiation direction control, substituting electrical actuation for mechanical systems and reducing overall mechanical complexity.
4Productivity
If multiple first apertures are used to form constructive interference, then the radiation efficiency is improved, but the manufacturing complexity increases
Solution Approach 1:
The waveguide radiation structure is segmented into multiple adjustable slots that can be independently controlled. Each slot contributes to the overall radiation pattern and can be optimized for constructive interference at specific frequencies and directions. This segmentation allows for improved radiation efficiency through coherent addition of electromagnetic fields while maintaining manufacturability through modular slot designs.
Solution Approach 2:
The multiple slots serve dual purposes: they individually contribute to radiation efficiency through constructive interference, and collectively provide frequency control and beam steering capabilities. This multi-functionality of the slot array reduces the need for separate components, simplifying manufacturing while achieving high radiation efficiency.
