Optical Data Transmission via Display Screen Orientation Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in maintaining stable communication between electronic devices using optical signals due to misalignment between display screens and solar panels, leading to timing issues in data transmission.
Innovation Solution
An electronic device equipped with a display part, a detection system to determine the direction of the display screen, and a controller that transmits data as an optical signal only when the screen is aligned in a predetermined direction, typically the gravity direction, after a predetermined period has passed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data transmission is performed by changing display brightness using optical signals, then communication between electronic devices is enabled, but communication stability deteriorates due to timing mismatch between optical signal output and positioning completion
Solution Approach 1:
The detection part detects the display screen direction in advance before data transmission begins. The controller waits for the display screen to be properly positioned (detected in predetermined direction) before initiating the optical signal transmission, ensuring timing synchronization between positioning completion and communication start
Solution Approach 2:
The detection part continuously monitors the display screen direction and provides feedback to the controller. The controller uses this feedback to determine when positioning is complete and to synchronize the optical signal transmission timing with the positioned state, ensuring stable communication
2Speed
If optical signal transmission is initiated immediately, then communication speed is improved, but communication reliability deteriorates due to misalignment between display and solar panel
Solution Approach 1:
Positioning detection is performed in advance before data transmission. The controller confirms proper alignment between display and solar panel through the detection part before initiating optical signal transmission, ensuring both speed and reliability
Solution Approach 2:
The system dynamically adjusts transmission timing based on real-time positioning detection. The controller waits for the display screen to be detected in the predetermined direction (indicating proper alignment) before initiating transmission, optimizing both speed and reliability based on actual positioning state

AI summary
An electronic device includes a display part having a light source which transmits an optical signal, a direction detection part for detecting a direction of orientation of a display screen of the display part, and a controller for transmitting data by the optical signal from the display part to an electronic timepiece when the direction of orientation of the display screen detected by the detection part faces a predetermined direction.
