Sliding Screen Magnetic Field Detection for System State Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional notebook computers with removable screens cannot enter a dormant state when the lid is closed at positions other than a preset sliding range, limiting user flexibility in operating modes.
Innovation Solution
An electronic device featuring a host, a first screen slidably connected to the host via a magnet module and a magnetic induction module, which detects the magnetic field to switch the host's system state regardless of the screen's position between slide positions, allowing the host to enter a dormant or operating state based on magnetic field strength thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the screen is allowed to slide to any position for user flexibility, then the adaptability is improved, but the system cannot enter dormant state at non-preset positions, reducing reliability
Solution Approach 1:
The patent replaces the mechanical position-detection system with a magnetic field detection system. Instead of using mechanical switches or sensors that only work at preset positions, the magnetic induction module continuously detects the magnetic field strength generated by the magnet module, enabling dormant state entry at any screen position along the sliding range.
Solution Approach 2:
The patent changes the detection parameter from discrete mechanical position signals to continuous magnetic field strength values. By monitoring the strength of the magnetic field rather than specific positional triggers, the system can determine screen closure state at any position along the sliding range, not just at predetermined locations.
2Adaptability or versatility
If magnetic field detection is used to enable dormant state at any position, then the adaptability is improved, but the device complexity increases due to additional magnet and sensor modules
Solution Approach 1:
The magnet module serves multiple functions: it provides magnetic attraction to hold the screen at desired positions and simultaneously generates the magnetic field for position detection. The magnetic induction module also serves dual purposes by detecting both the presence and position of the screen for dormant state control. This multi-functionality reduces the need for separate dedicated components.
Solution Approach 2:
The magnetic field acts as an intermediary between the screen position and the control system. Instead of requiring direct mechanical contact or complex optical sensors, the magnetic field provides a simple, contactless means of detecting screen position and triggering dormant state entry, simplifying the overall system architecture.
