Display Device Bracket Latch and Pin Coupling Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices lack a secure mechanism for firmly fixing a head to a plate, which can lead to instability and potential damage or misalignment during assembly and use.
Innovation Solution
A display device design featuring a latch on a module cover and a fixing pin on a bracket, where the latch and pin work together to securely attach the bracket to the module cover, providing a robust coupling mechanism that includes elastic and protruding elements for enhanced stability and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple coupling structure is used between the bracket and module cover, then the device complexity is reduced, but the reliability of fixing the head to the plate deteriorates
Solution Approach 1:
The coupling structure is divided into separate functional elements: the latch (with first and second latches) on the module cover and the corresponding fixing pin (with elastic portion, transfer portion, and fastening portion) on the bracket. This segmentation allows each component to perform its specific function while maintaining overall simplicity
Solution Approach 2:
The fixing pin is inserted through the pin hole in the bracket and engages with the latch structure on the module cover. The elastic portion of the fixing pin is received within the pin housing, creating a nested arrangement where components fit within each other to provide secure fixation without adding external complexity
2Reliability
If a secure fixing mechanism with latch and pin is implemented, then the reliability of fixing the head to the plate is improved, but the device complexity increases
Solution Approach 1:
The latch and fixing pin structures are integrated into the existing module cover and bracket designs. The first and second latches are formed as part of the module cover, while the fixing pin with its elastic and fastening portions is integrated into the bracket, merging multiple functions into unified components rather than adding separate discrete elements
Solution Approach 2:
The elastic portion of the fixing pin automatically provides the necessary force to engage with the latch structure and maintain secure fixation. The self-service elastic mechanism eliminates the need for additional fastening tools or complex locking mechanisms, achieving reliable fixing through the inherent properties of the components

AI summary
A display device can include a display panel; a module cover disposed at a rear of the display panel and coupled to the display panel; a plate disposed at a rear of the module cover; a bracket disposed between the module cover and the plate, and fixed to the plate; and a coupling unit fixing the bracket to the module cover, in which the coupling unit includes a latch disposed at a rear surface of the module cover, and a fixing pin mounted on the bracket and coupled to the latch.
