Display Apparatus Magnetic Latch for Ceiling Mount Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display modules installed on ceilings or inclined surfaces are prone to separation from their frames due to constant forces or unexpected impacts, necessitating a safety mechanism to prevent detachment.
Innovation Solution
A magnetic coupling device with a separation prevention system, comprising a rotatable latch and catch mechanism, utilizes magnetic attraction and repulsion forces to lock and unlock the display module to the frame, ensuring secure attachment and easy detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a magnet is used to couple the display module to the frame for simplicity of structure and ease of assembly, then the assembly process is simplified and structure is more compact, but the display module may be separated from the frame under constant force or unexpected impact when installed on ceilings or inclined surfaces
Solution Approach 1:
The coupling system is divided into two independent functional components: a magnetic coupling device for primary attachment and a separation prevention device for safety. This segmentation allows each component to perform its specific function optimally without compromising the other.
Solution Approach 2:
The separation prevention device is pre-configured in a locked state that prevents detachment before any external force is applied. The latch mechanism is designed to engage automatically upon assembly, providing preliminary protection against separation before the display module is actually installed on the ceiling or inclined surface.
2Reliability
If a safety device is added to prevent separation of display modules from the frame, then connection stability is improved, but the device complexity increases
Solution Approach 1:
The latch mechanism is actuated by magnetic force rather than traditional mechanical keys or tools. The magnetic field replaces complex mechanical actuation systems, allowing the latch to switch between locked and unlocked states through magnetic attraction and repulsion forces, thereby simplifying the overall device structure.
Solution Approach 2:
The magnetic coupling device serves dual functions: it provides the primary magnetic attraction for holding the display module to the frame, and it simultaneously acts as the actuation mechanism for the separation prevention latch. This multi-functionality eliminates the need for separate actuation mechanisms, reducing device complexity.
3Ease of operation
If the latch is designed to be rotatable between locking and unlocking positions by magnetic force, then ease of operation is improved, but the device complexity increases
Solution Approach 1:
Traditional mechanical key-operated or tool-operated latch mechanisms are replaced with a magnetic actuation system. The magnetic coupling device generates magnetic forces that directly rotate the latch between locked and unlocked positions, eliminating the need for complex mechanical actuation components.
Solution Approach 2:
The magnetic coupling device automatically provides the force needed to operate the latch mechanism. When brought into proximity, the magnetic attraction or repulsion automatically rotates the latch to the appropriate position without requiring external mechanical intervention, making the system self-operating.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents display modules from separating from the frame under external forces or impacts, maintaining stability and ease of assembly, even when installed on non-traditional surfaces.
Implementation Method 1
a magnetic coupling device configured to couple the frame to the display module by pulling the display module toward the frame by using the magnetic attraction force
Implementation Method 2
a first magnetic member installed in the bracket to fix the latch to the locking position by using the magnetic attraction force
Implementation Method 3
when the other of the N pole and the S pole is moved to the front of the latch, the latch may be rotated from the locking position to the unlocking position by the magnetic repulsion force
