Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an electronic antenna performs complete signal searching by detecting all parameter combinations (direction, gain, polarity), then the optimum signal source can be found, but the convergence time increases significantly (about 0.5 second)
Solution Approach 1:
The patent segments the parameter detection process by dividing all possible parameter combinations into multiple groups. Instead of detecting all combinations sequentially, the system detects a first group of combinations, determines a first optimum signal source, then detects a second group of combinations based on the first result, and determines a second optimum signal source. This segmentation reduces the time required for complete signal searching while maintaining detection accuracy.
Solution Approach 2:
The patent applies preliminary action by performing initial detection of a first group of parameter combinations to obtain a first optimum signal source before proceeding to detect the second group of combinations. This preliminary detection provides guidance for subsequent detection, allowing the system to focus resources on more promising parameter combinations and reduce overall convergence time.
2Device complexity
If a fishbone antenna searches in one specific direction, then the device complexity is reduced, but the signal quality decreases when the signal direction differs from the antenna reception direction
Solution Approach 1:
The patent implements dynamics by enabling the antenna to dynamically adjust its reception direction based on detected signal parameters. Rather than being fixed in one direction like a traditional fishbone antenna, the system can change its orientation to match the direction of incoming signals, thereby maintaining high signal quality while keeping the antenna structure relatively simple.
Solution Approach 2:
The patent applies parameter changes by modifying the antenna's reception direction parameter based on detected signal characteristics. The system detects parameters such as direction of arrival and adjusts the antenna orientation accordingly, allowing the antenna to adapt to different signal directions without requiring complex multi-element arrays.

AI summary
A wireless signal receiving system, having an antenna, for receiving a wireless signal comprising a channel. The system also includes a tuner, coupling to the antenna, for converting the frequency of the wireless signal to generate a conversion signal. In addition, the system includes a processing unit, coupling to the tuner, for controlling the signal receiving direction of the antenna to detect the wireless signals of a first direction and a second direction, using the tuner to generate a first conversion signal and a second conversion signal so as to obtain a first reference value and a second reference value, and generating a control signal according to the first reference value and the second reference value to control the selected receiving direction of the antenna while the antenna is to receive the wireless signal of the channel.
