Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single antenna is used in the mobile terminal, then the device structure is simple, but the communication quality deteriorates when the terminal approaches the human body or is held in different positions
Solution Approach 1:
The patent divides the antenna system into multiple independent antenna elements (first antenna and second antenna) with different spatial orientations. Each antenna is designed to be effective in specific holding scenarios, allowing the system to segment the coverage space and provide reliable communication across various user positions and gestures.
Solution Approach 2:
The patent implements dynamic antenna selection based on real-time detection of holding gestures using sensor modules. The system dynamically switches between different antennas according to the detected gesture state, making the antenna configuration adaptive to changing user interactions rather than fixed.
2Reliability
If multiple antennas are used to improve communication quality in different holding states, then the communication reliability improves, but the device complexity increases
Solution Approach 1:
The patent employs sensor detection modules that automatically detect holding gestures and trigger the corresponding antenna selection without user intervention. The system serves itself by using the sensor data to autonomously determine the optimal antenna configuration, reducing the need for complex manual control mechanisms.
Solution Approach 2:
The patent changes the operational parameters of the antenna system by switching between different antennas based on detected gesture parameters. Instead of using a single complex antenna, the system varies which antenna element is active according to the holding state, effectively managing complexity through parameter-based selection.
3Adaptability or versatility
If antenna switching is implemented based on gesture detection, then the adaptability to different holding states improves, but the system complexity increases
Solution Approach 1:
The patent uses a universal sensor detection module that serves multiple functions: detecting various holding gestures, determining orientation, and triggering appropriate antenna selections. This multi-functional approach reduces the need for separate detection systems for each gesture type, managing complexity through consolidated functionality.

AI summary
The present disclosure relates to an antenna matching method and apparatus, and mobile terminal. The antenna matching method comprises: determining whether the mobile terminal is currently in a communication state based on status information; in response to determining that an operation mode of the mobile terminal in the communication state is a first operation mode, obtaining gesture data of a user for the mobile terminal by using a sensor detection module; and selecting a target antenna corresponding to the holding gesture state from a plurality of antennas based on holding gesture state corresponding to the gesture data. Therefore, free switching of the antennas is achieved.
