Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If beam tracking is performed by request when necessary, then device complexity is reduced, but speed of beam tracking decreases
Solution Approach 1:
The patent segments the filtering process into two distinct filtering units: a first filtering unit that processes link quality data at a normal speed, and a second filtering unit that processes the same data at an accelerated speed. This segmentation allows the system to obtain both stable baseline measurements and rapid change detection capabilities, enabling fast beam tracking when blockages occur without requiring complex continuous high-speed processing
Solution Approach 2:
The patent applies partial action by using the second filtering unit only when necessary for blockage detection, rather than continuously operating at maximum speed. The system compares the accelerated filtering results against the normal filtering baseline only when changes are detected, allowing rapid response to blockages while avoiding the continuous complexity and resource consumption of constant high-speed processing
2Reliability
If single filtering is used for blockage detection, then device complexity is reduced, but reliability of blockage detection decreases
Solution Approach 1:
The patent divides the filtering system into two parallel filtering units with different processing speeds. The first filtering unit provides stable baseline link quality measurements, while the second filtering unit detects rapid changes indicative of blockages. This segmentation enables reliable blockage detection by comparing accelerated processing results against normal processing baselines, improving detection reliability without requiring a single overly complex filtering system
Solution Approach 2:
The system implements feedback by continuously comparing the results from the first filtering unit and the second filtering unit. When the second filtering detects significant deviations from the first filtering's baseline, the system triggers beam tracking operations. This feedback mechanism ensures reliable blockage detection by using the normal filtering results as a reference for validating anomalies detected by the accelerated filtering
3Speed
If beam tracking is performed continuously, then beam tracking speed is improved, but loss of time for unnecessary tracking increases
Solution Approach 1:
The patent uses the second filtering unit to perform partial excessive processing only when blockage conditions are suspected. By accelerating the filtering process selectively and comparing it against the normal filtering baseline, the system can trigger beam tracking only when necessary, avoiding continuous tracking operations and reducing time wasted on unnecessary beam adjustments during stable transmission conditions
4Reliability
If rapid beam tracking is implemented, then stability of media transmission is improved, but device complexity increases
Solution Approach 1:
The patent segments the transceiver device into distinct functional units: a first filtering unit for normal operation, a second filtering unit for rapid blockage detection, and a beam tracking unit activated only when needed. This segmentation allows rapid beam tracking to be implemented without making the entire transceiver device complex, as each unit performs its specific function independently and the rapid tracking capability is activated only when stability issues are detected
