Foldable Cover Imaging Timing Control via Magnetic Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In flat-type electronic devices, it is difficult to accurately image a photographic subject due to the challenge of maintaining constant imaging timing when the lid cover section closes, as the tilt of the lid cover section is hard to detect and control.
Innovation Solution
An electronic device with a foldable protective cover that includes an open/close detecting section to detect the angle of the cover and output a signal for the imaging section, ensuring consistent imaging timing by pausing the cover at a predetermined angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the lid cover section merely closes to cover the front surface of the device case, then the structure is simple, but the imaging timing cannot be kept constant and imaging accuracy deteriorates
Solution Approach 1:
The patent replaces the mechanical tilt detection system with a magnetic field-based detection system. A magnet is attached to the lid cover section and a magnetic sensor is mounted on the device case. The magnetic sensor detects the position of the magnet to determine the tilt angle of the lid cover section, eliminating the need for complex mechanical tilt detection mechanisms while achieving precise imaging timing control.
2Ease of operation
If the lid cover section is tilted at an arbitrary angle, then the ease of operation is improved, but the imaging accuracy deteriorates due to inconsistent imaging timing
Solution Approach 1:
The patent implements a feedback control system where the magnetic sensor continuously monitors the position of the magnet on the lid cover section. When the lid cover section reaches the predetermined tilt angle, the magnetic sensor detects the magnet's position and generates a detection signal that triggers the imaging operation. This feedback mechanism ensures that imaging always occurs at the correct timing regardless of how the user tilts the lid cover section, maintaining imaging accuracy while preserving operational flexibility.
