Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Full-screen mobile devices face radio frequency interference issues due to high camera frame rates during video shooting or video chatting, which affect the antenna's signal, and existing hardware upgrades provide limited improvements at increased costs.
Innovation Solution
An electromagnetic interference control method that involves determining the operating frequencies of the camera and antenna, adjusting the camera's frame rate to minimize interference by selecting alternative frequencies with lower interference impact, and using pre-configured mapping relationships to optimize the camera's operating frequency and frame rate settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the camera frame rate is increased to improve video quality, then video shooting quality is improved, but interference to the antenna's radio frequency signal increases
Solution Approach 1:
The patent dynamically adjusts the camera frame rate based on the operating state of the antenna. When the antenna is actively transmitting or receiving signals, the system automatically reduces the camera frame rate to minimize electromagnetic interference, while allowing higher frame rates when the antenna is inactive. This dynamic adaptation resolves the contradiction by making the frame rate flexible rather than fixed.
Solution Approach 2:
The system changes the operating parameters of the camera (frame rate) based on the antenna's operational status. By monitoring the antenna's working state and adjusting the camera's frame rate parameter accordingly, the patent optimizes both video quality and radio frequency signal stability, resolving the interference issue without permanent hardware modifications.
2Object-affected harmful factors
If hardware upgrades are implemented to reduce interference, then interference reduction effect is achieved, but device cost increases
Solution Approach 1:
The patent replaces physical hardware modifications with a software-based control mechanism. Instead of adding shielding materials, filters, or other physical components to reduce interference, the system uses intelligent software algorithms to dynamically adjust the camera frame rate based on antenna operational status, achieving interference reduction without increasing device cost.
Solution Approach 2:
The system implements self-service interference management by automatically monitoring the antenna's operating state and autonomously adjusting the camera frame rate to minimize interference. This self-regulating mechanism eliminates the need for additional hardware components or manual intervention, reducing both cost and complexity while maintaining effective interference control.

AI summary
Disclosed are an electromagnetic interference control method and a related product. The method comprises: when a video function of a camera is enabled, acquiring a first working frequency of the camera, and acquiring a second working frequency of an antenna; if the second working frequency is subjected to interference, acquiring a target frame rate range; determining, according to a pre-set mapping relationship between a working frequency of the camera and a frame rate of the camera, a working frequency of the camera corresponding to each frame rate in the target frame rate range, and constituting a working frequency list by means of working frequencies of the camera corresponding to all frame rates; determining, in the working frequency list, at least one third working frequency with the interference thereof to the second working frequency being less than the interference of the first working frequency to the second working frequency; and selecting a third working frequency from among the at least one third working frequency as a first target working frequency, determining a first target frame rate, and realizing the video function according to the first target working frequency and the first target frame rate. Thus, when a video function is realized, the interference of a frame rate to an antenna is reduced.
