Conductive Pattern Signal Timing for Camera Interference Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in adjusting the strength of data signals transmitted through conductive patterns while operating cameras, leading to potential interference and image degradation.
Innovation Solution
The electronic device incorporates a communication processor that controls a first and second conductive pattern, adjusting the strength of the data signal to be lower than a preset strength when the camera is operated, and transmitting data signals through both patterns in different time periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data signal strength is increased for reliable transmission, then transmission reliability improves, but camera operation interference increases causing image degradation
Solution Approach 1:
The patent implements time-division multiplexing where data signal transmission occurs in specific time periods (first time period) while camera operation occurs in other time periods (second time period). This periodic separation allows both functions to operate at full strength without interference, resolving the contradiction between transmission reliability and camera operation quality.
Solution Approach 2:
The patent divides the operation into segmented time periods: first time period for data signal transmission through conductive patterns, and second time period for camera operation. This temporal segmentation allows each function to operate independently at optimal levels without mutual interference.
2Object-affected harmful factors
If data signal strength is reduced during camera operation, then camera operation interference decreases, but transmission reliability deteriorates
Solution Approach 1:
The system alternates between first time period (data transmission with full signal strength) and second time period (camera operation with reduced or no data transmission). This periodic action ensures that when camera operation occurs, interference is minimized, while transmission reliability is maintained during dedicated data transmission periods.
3Productivity
If multiple conductive patterns are used for data transmission, then transmission capacity increases, but noise and interference during camera operation increases
Solution Approach 1:
The patent controls multiple conductive patterns (first and second conductive patterns) to operate in a time-division manner. During the first time period, data signals are transmitted through one or more conductive patterns. During the second time period when the camera operates, data signal transmission is reduced or stopped. This periodic control allows multiple conductive patterns to provide high transmission capacity when needed while minimizing noise and interference during camera operation.

AI summary
An electronic device includes: a camera; a first conductive pattern separated from the camera by a first distance; a second conductive pattern separated from the camera by a second distance, the second distance; and a communication processor to transmit a data signal to an external electronic device and to receive a control signal from the external electronic device. The communication processor transmits a first data signal to the external electronic device by controlling the first conductive pattern and the second conductive pattern in a first time period indicated by the control signal transmitted from the external electronic device; transmits a second data signal to the external electronic device by controlling the second conductive pattern in a second time period; and adjust a strength of the first data signal to be lower than a preset strength.
