Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If shielding material is used to package camera module, then camera impact on antenna performance is decreased, but connector of camera module still leaks some signals affecting antenna performance
Solution Approach 1:
The patent changes the operating parameters of the camera module, specifically adjusting the camera clock frequency and control signals, to eliminate intermodulation interference with the antenna while maintaining normal camera functionality
Solution Approach 2:
The patent implements a feedback mechanism where the system detects antenna signal quality and dynamically adjusts camera module parameters in real-time to prevent interference, ensuring continuous optimal performance
2Volume of moving object
If camera is placed closer to antenna to reduce device size, then device compactness is improved, but intermodulation interference between camera signal and antenna signal increases
Solution Approach 1:
The patent adjusts camera clock frequency parameters dynamically to avoid generating intermodulation products that interfere with antenna operating frequencies, enabling compact layout without performance degradation
Solution Approach 2:
The patent makes the camera module parameters dynamic and adjustable based on antenna usage state, allowing the system to adapt between compact operation and interference-free operation as needed

AI summary
Embodiments of the present invention relate to the field of communications technologies, and provide a method and an apparatus for preventing a camera from interfering with an antenna, and an electronic device. The method includes: after a camera is started, detecting whether an electronic device successfully camps on a network; if the electronic device successfully camps on the network, obtaining a network resource on which the electronic device camps, and a current configuration parameter of the camera; determining whether an antenna is interfered by a signal generated by the camera; if the antenna is interfered by the signal generated by the camera, obtaining a configuration parameter by using which the antenna is not interfered; and modifying the current configuration parameter of the camera by using the obtained configuration parameter by using which the antenna is not interfered. The present invention resolves a problem that a connector of a camera module leaks some signals, and consequently antenna performance of the electronic device is affected. Therefore, interference from the camera to the antenna is eliminated and stability of antenna performance is improved.
