Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a higher transmission rate is used with wider bandwidth and higher operating frequency, then transmission speed is improved, but signal attenuation increases and communication dead spots occur more frequently
Solution Approach 1:
The patent implements dynamic adjustment of antenna azimuth angles based on real-time signal quality detection. The system continuously monitors transmission quality and rotates the external antenna to optimal angles, making the antenna orientation dynamic rather than fixed, thereby maintaining reliable connection even at high transmission rates
Solution Approach 2:
The system changes physical parameters (antenna azimuth angles) to optimize signal reception. By adjusting the antenna orientation parameters to different angles, the system adapts to environmental conditions and maintains signal stability while using high-frequency transmissions
2Reliability
If automatic channel selection function is used to select channels with less interference, then transmission quality is improved, but the solution does not consider user device wireless parameters such as antenna pattern and access point channel utilization
Solution Approach 1:
The patent implements a feedback mechanism where the system detects broadcast information from multiple access points, evaluates channel utilization and interference levels, and uses this information to select the optimal access point and antenna angle. This closed-loop feedback system adapts to real-time environmental conditions and device-specific parameters
Solution Approach 2:
Before establishing a wireless connection, the system performs preliminary detection of broadcast information from all available access points, evaluating channel utilization and interference levels in advance. This preliminary action allows the system to select the optimal access point and antenna orientation before actual data transmission begins
3Reliability
If external directional antenna is used with azimuth angle adjustment, then signal reception is improved, but device complexity increases
Solution Approach 1:
The system performs self-adjustment by automatically detecting signal quality and rotating the external antenna to optimal angles without user intervention. The processing circuit autonomously monitors transmission quality and controls antenna orientation, making the complex system self-managing and reducing the perceived complexity for the user
