Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a full frequency search is performed by searching one by one all communication channels at all possible reading directions, then optimal parameters for each channel can be found, but the searching process consumes much time
Solution Approach 1:
The patent segments the full frequency search process into two distinct phases: a coarse search phase that quickly identifies candidate channels and directions, and a fine search phase that precisely determines optimal parameters. This segmentation allows the system to avoid exhaustive searching while still achieving accurate parameter optimization.
Solution Approach 2:
The patent performs preliminary actions by first conducting a coarse search to identify candidate channels and reading directions before performing the fine search. This preliminary identification narrows down the search space, enabling the system to achieve optimal parameters without consuming excessive time on exhaustive searching.
2Reliability
If the smart antenna parameters are adjusted to track environmental variations and maintain optimal performance, then signal receiving performance is improved, but the system complexity increases
Solution Approach 1:
The patent implements a self-service mechanism where the smart antenna system automatically performs parameter adjustment and channel tracking without requiring complex external control systems. The system uses the recorded optimal parameters from the frequency search to autonomously adjust its configuration in response to environmental variations, simplifying the overall system architecture while maintaining high reliability.
Solution Approach 2:
The patent employs parameter changes as the core mechanism for adapting to environmental variations. By recording optimal parameters during the frequency search and adjusting these parameters based on channel status changes, the system achieves reliable signal reception without requiring complex structural modifications or additional hardware components.

AI summary
An adjusting method for a smart antenna is provided. The adjusting method divides all possible reading directions of the smart antenna into a plurality of scanning directions and a plurality of idle directions by a first form. In searching for the optimal parameters of each of a plurality of communication channels, the adjusting method firstly adjusts the reading direction according to the plurality of scanning directions, and then adjusts the reading direction according to the plurality of idle directions. Further, the first form remain updated in accordance the process of searching for the optimal parameters of each of the communication channels, thus effectively saving the time spent on the full frequency scanning process. Further, the optimal parameters of each of the communication channels are recorded in a second form, so that the smart antenna is regulated according to the second form.
