Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a traditional antenna is closely attached to the glass window, then the aesthetic and transparency of the glass window is improved, but the antenna cannot effectively radiate electromagnetic energy due to strong attenuation by glass, resulting in low antenna gain
Solution Approach 1:
The patent transitions from a single-layer antenna design to a dual-layer substrate structure with radiation parts on both sides of the glass window. This dimensional change allows the antenna to radiate electromagnetic energy in both directions, overcoming the attenuation problem caused by glass while maintaining transparency and aesthetic appearance from both sides of the window.
Solution Approach 2:
The patent employs a composite structure combining dielectric substrates, metal radiation parts, and glass windows. The dielectric substrates provide mechanical support and electrical isolation, while the metal radiation parts enable electromagnetic radiation. This composite material approach allows the antenna to achieve both transparency (through thin dielectric and metal layers) and effective radiation (through optimized radiation part designs).
2Illumination intensity
If a traditional antenna is used with a transparent glass window, then transparency is maintained, but the aesthetic of the whole surface is influenced and radiation efficiency is reduced
Solution Approach 1:
By placing radiation parts on both sides of the glass window, the antenna can radiate energy in both directions, effectively utilizing the space around the glass rather than being constrained to one side. This reduces energy loss due to glass attenuation while maintaining the transparent appearance from both sides.
Solution Approach 2:
The patent optimizes parameters such as the thickness of dielectric substrates, the size and shape of radiation parts, and the spacing between layers to achieve a balance between transparency and radiation efficiency. By carefully controlling these parameters, the antenna minimizes energy loss while maintaining aesthetic appearance.
3Illumination intensity
If the antenna structure is designed to maintain transparency, then aesthetic integration is improved, but the complexity of the antenna structure increases
Solution Approach 1:
The antenna is segmented into multiple functional layers: first and second dielectric substrates, reference electrode layers, radiation parts, and feeding structures. Each layer has a specific function, allowing the overall structure to achieve transparency while maintaining effective radiation. The segmentation enables independent optimization of each component for both aesthetic and performance requirements.
Solution Approach 2:
The dielectric substrates serve multiple functions: providing mechanical support, electrical isolation, and structural integrity. The radiation parts on both sides enable bidirectional radiation while maintaining transparency. This multi-functionality reduces the need for additional components, managing structural complexity while achieving the desired transparency and performance.
