Display Screen Mounting Head with Self-Latching and Tool-Free Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display screen mounting devices lack efficient self-latching and easy release mechanisms, making it difficult to safely remove larger screens without tools and requiring continued force for disengagement.
Innovation Solution
A mounting head with a latch mechanism that automatically locks and releases, allowing for secure attachment and easy detachment without continuous force application, featuring a projection that moves within a channel and a lever biased by a spring for automatic locking and manual unlocking, along with an articulated support arm with an adjustable coil spring and tool-free adjustment mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a quick release mechanism is used to enable easy detachment of display screens, then ease of operation is improved, but reliability deteriorates because the screen may detach accidentally when the release lever is released
Solution Approach 1:
The latch mechanism automatically engages and locks the projection in the channel when the male and female parts are brought together, performing the locking action in advance before the user needs to operate the release lever. This preliminary automatic engagement ensures the screen is securely locked without requiring user intervention, preventing accidental detachment while maintaining easy release when intentionally triggered.
2Reliability
If a latch mechanism is added to prevent accidental detachment, then reliability is improved, but device complexity increases due to additional components
Solution Approach 1:
The latch mechanism is merged with the lever assembly, where the lever serves dual purposes: as a manual release component and as part of the locking structure. The latch projects from the lever and engages with the projection's notch, combining the lever's movement function with the latch's locking function into a single integrated component, thereby reducing overall device complexity while maintaining secure locking.
Solution Approach 2:
The spring provides automatic biasing force to the latch mechanism, causing it to self-engage with the projection's notch when the male and female parts are assembled. The spring's elastic energy automatically performs the locking action without requiring additional actuators, motors, or complex control systems, achieving reliable secure locking through simple passive mechanical self-service.
3Ease of operation
If continued force is applied to release the mounting, then ease of operation is improved for disengagement, but loss of time increases due to sustained force requirement
Solution Approach 1:
The release mechanism operates through periodic action rather than continuous force. When the lever is pushed, it temporarily overcomes the spring bias to disengage the latch from the projection's notch. Once the latch is freed, the spring immediately returns the lever to its original position, completing the release cycle. This periodic mechanism allows disengagement with a brief lever push rather than requiring sustained force application over time.
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
Enables secure, automatic self-latching and easy manual release of display screens, allowing safe removal with both hands and providing adjustable support without requiring tools, enhancing usability and simplicity.
Implementation Method 1
the latch mechanism is movable under a biasing force to a release position
Implementation Method 2
The articulated support arm may further include a coil spring to provide an adjustable support force at the display screen end

AI summary
The invention relates to devices for mounting display screens, including conventional computer monitors, flat screen displays, television screens, tablets, laptops, touch screens and the like. In particular, the invention relates to a mounting head 200 for mounting a display screen, a device for mounting two display screens, and an articulated support arm 100 for mounting a display screen. The mounting head 200 provides an automatic, self-latching/locking function and a manual unlocking function, which allows the male and female sections 210,250 to be unlocked/released and then separated without the continued application of a release force to the mounting head. The device for mounting two display screens to a support provides a convenient way of mounting two displays to a single support. The spacing between the displays is adjusted with a single control which simultaneously separates or brings together the two screen mountings. The device can be configured to mount the two screens horizontally side-by-side or vertically one above the other. The articulated support arm 100 provides an adjustment mechanism 146 which does not require tools to operate, and which is conveniently integrated into the body of the support arm with the components generally lying on the axis of the arm.
