Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If millimeter wave links are used for wireless communication, then transmission speed is improved, but signal attenuation and power consumption increase
Solution Approach 1:
The patent changes the operating parameters by switching between millimeter wave links and low-frequency links based on communication conditions. When millimeter wave links experience high signal attenuation or blockage, the system transitions to low-frequency links, thereby adjusting the operational parameters to maintain reliable communication while reducing power consumption.
Solution Approach 2:
The patent implements dynamic link selection and switching between millimeter wave and low-frequency links based on real-time communication conditions. This dynamic adaptation allows the system to respond to changing environmental conditions, switching to more reliable links when millimeter wave signals are degraded, thus optimizing power consumption while maintaining transmission speed.
2Speed
If millimeter wave links are used for wireless communication, then transmission speed is improved, but coverage distance is reduced
Solution Approach 1:
The patent changes the frequency parameter of the wireless link based on coverage requirements. When millimeter wave links are used for high-speed transmission but encounter coverage limitations or blockage, the system switches to low-frequency links that provide longer coverage distance, thereby adjusting operational parameters to balance speed and coverage.
Solution Approach 2:
The patent implements dynamic switching between millimeter wave and low-frequency links based on real-time assessment of coverage conditions. This dynamic adaptation ensures that the system uses millimeter wave links for high-speed transmission when coverage is adequate, but switches to low-frequency links when coverage distance is insufficient, optimizing both speed and coverage.
3Productivity
If multiple links are established in multi-link devices, then communication efficiency is improved, but device complexity increases
Solution Approach 1:
The patent implements multi-link devices that can operate in multiple frequency bands (millimeter wave and low-frequency) simultaneously. This multi-functionality allows a single device to leverage the high speed of millimeter wave links and the long coverage of low-frequency links, improving overall communication efficiency while managing complexity through unified device architecture.
Solution Approach 2:
The patent introduces dynamic link management and switching mechanisms that allow multi-link devices to adaptively select and switch between different frequency bands based on communication conditions. This dynamic control simplifies the management of multiple links by automatically selecting the most appropriate link for each communication task, thereby improving efficiency without proportionally increasing complexity.
