Magnetic Display Module Latch for Fast Chassis Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display module attachment mechanisms are inefficient for easy removal and reattachment, particularly in large display systems like digital billboards, as they often require complex manual operations or additional securing structures.
Innovation Solution
A magnetically-actuated latch mechanism that allows for secure attachment and easy detachment of display modules to a support chassis using a tool, featuring a movable magnetizable plate and linkage mechanism for controlled engagement and disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional manual attachment mechanisms are used, then structural integrity is maintained, but ease of operation deteriorates due to complex manual operations required for attachment and detachment
Solution Approach 1:
The patent replaces manual mechanical operations with a magnetic field-based actuation system. A magnet mounted on a tool interacts with a magnetizable plate on the display module to automatically actuate the latch mechanism, eliminating the need for complex manual operations while maintaining structural integrity through the engineered magnetic engagement system
Solution Approach 2:
The patent introduces a magnetizable plate as an intermediary component between the external magnet and the latch mechanism. This plate serves as a mediator that converts external magnetic force into controlled mechanical motion of the latch, simplifying the overall system while maintaining reliable attachment and detachment functionality
2Reliability
If secure attachment is ensured through robust latch mechanisms, then reliability is improved, but ease of operation worsens due to difficulty in detachment for maintenance
Solution Approach 1:
The patent creates a dynamic latch system that can transition between locked and unlocked states based on external magnetic actuation. The latch member is designed to be held in a secure engaged position during normal operation but can be easily released when a magnet is brought near, allowing the same mechanism to provide both secure attachment and easy detachment
Solution Approach 2:
The patent replaces manual mechanical manipulation required for detachment with magnetic field actuation. The magnetizable plate responds to external magnetic force to automatically actuate the latch mechanism, making detachment as easy as bringing a magnet close while maintaining secure attachment during normal use

AI summary
A display module comprises a support, a plurality of light-emitting elements coupled to the support and a latch mechanism to removeably couple the support to a chassis. The latch mechanism includes a movable member, a latch member, and a linkage mechanism. The movable member is moved from a first position to a second position when magnetically engaged by a tool magnet. The latch member moves between a first latch member position and a second latch member position and can engage a chassis mating structure when in the first latch member position. The linkage mechanism mechanically connects the movable member to the latch member so that they move together such that the latch member is in the first latch member position when the movable member is in the first position and is in the second latch member position when the movable member is in the second position.
