Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the frequency of signals transmitted by antenna modules is increased to achieve broader bandwidth and faster speeds, then bandwidth and transmission speed are improved, but radiation loss worsens leading to decreased antenna gain and heat accumulation
Solution Approach 1:
The patent applies local quality by introducing a dielectric layer with spatially varying dielectric constant within the antenna module. The dielectric constant changes at different locations (different layers with different constants), creating localized electromagnetic property variations that reduce radiation loss in specific regions while maintaining high-frequency signal transmission capabilities, thereby resolving the contradiction between transmission speed and radiation loss
Solution Approach 2:
The patent employs composite materials by combining multiple dielectric layers with different dielectric constants within the antenna structure. This composite dielectric structure optimizes electromagnetic wave propagation at high frequencies while reducing overall radiation loss, enabling both high transmission speed and reduced energy loss simultaneously
2Adaptability or versatility
If the frequency of signals transmitted by antenna modules is increased to achieve broader bandwidth, then bandwidth is improved, but radiation loss worsens leading to decreased antenna gain
Solution Approach 1:
The patent uses local quality by implementing a dielectric layer with position-dependent dielectric constant that optimizes electromagnetic field distribution across different frequency bands. This localized optimization maintains stable antenna gain across the broad bandwidth range, preventing the gain degradation that normally occurs at higher frequencies
Solution Approach 2:
The patent applies parameter changes by varying the dielectric constant parameter of the insulating layer at different spatial locations. This parameter variation compensates for frequency-dependent losses, maintaining consistent antenna gain performance across the expanded bandwidth operating range
3Speed
If the frequency of signals transmitted by antenna modules is increased, then transmission speed is improved, but heat accumulation occurs due to increased radiation loss
Solution Approach 1:
The patent converts the harmful effect of high-frequency radiation loss into a beneficial outcome by using the dielectric layer with varying dielectric constant to redirect and contain electromagnetic energy. This prevents energy from being lost as radiation and heat, instead guiding it through the optimized dielectric path, thereby maintaining high transmission speed while reducing heat accumulation
