Sensor-Based Antenna Selection for Mobile Handling Conditions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices face challenges in determining their handling conditions, which affect antenna performance and overall system operation, as existing technologies do not effectively account for how the device is being held or positioned relative to the user's body.
Innovation Solution
A mobile device equipped with left and right capacitive proximity sensors, an accelerometer, and an ambient light proximity sensor, along with a processor that combines data from these sensors to determine the handling condition, allowing for adjustments in antenna selection and configuration based on the device's orientation and proximity to the user's head.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors are used to detect handling condition, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The sensor system is segmented into specialized sensors placed at specific locations: left capacitive proximity sensor on the left side, right capacitive proximity sensor on the right side, ambient light proximity sensor inside the device, and accelerometer. Each sensor segment detects specific aspects of handling condition, and the processor integrates these segmented measurements to achieve comprehensive and precise handling condition detection.
2Reliability
If antenna selection is optimized based on handling condition, then communication reliability is improved, but processing requirements increase
Solution Approach 1:
The system performs preliminary detection of handling condition using multiple sensors before antenna selection is made. The processor continuously monitors sensor inputs (capacitive proximity, ambient light, accelerometer data) to determine handling condition in advance, then selects the appropriate antenna based on this pre-determined condition, optimizing communication reliability without requiring complex real-time processing during actual transmission.
