Display Cover Latch Assembly for Thin I/O Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in achieving a thin and lightweight design while preventing sharp edges and facilitating easy assembly and maintenance, particularly in the integration of input/output units and covers.
Innovation Solution
A display device design featuring a bracket that forms a rear surface with a back cover, integrally formed brackets for stability, and a coupling mechanism using a protrusion and latch to overlap covers, ensuring smooth assembly and preventing sharp edges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bracket and back cover are used to cover input/output units, then protection and structural integrity are improved, but device thickness increases
Solution Approach 1:
The bracket and back cover are merged into a single integrated component that performs both protective and structural functions. This integration eliminates the need for separate bracket and back cover parts, reducing overall device thickness while maintaining protection of input/output units and structural integrity.
2Ease of manufacture
If brackets are separately formed, then manufacturing flexibility is improved, but assembly complexity and maintenance difficulty increase
Solution Approach 1:
Multiple bracket components are merged into a single integrally formed bracket structure. This reduces the number of parts that need to be assembled, simplifying assembly procedures and maintenance operations while maintaining manufacturing flexibility through appropriate formation processes.
3Strength
If covers are joined with rigid connections, then structural strength is improved, but assembly ease and disassembly for maintenance deteriorate
Solution Approach 1:
The coupling mechanism is segmented into distinct coupling and decoupling actions. The protrusion and latch structure allows the cover to be easily coupled by simple insertion while maintaining strong structural connection, and easily decoupled by releasing the latch mechanism, achieving both strength and operational ease.
4Productivity
If the back cover end is positioned adjacent to the bracket, then space utilization is improved, but sharp edges may form causing safety issues
Solution Approach 1:
The end of the back cover is formed with a curved or rounded surface instead of a sharp edge, eliminating safety hazards while maintaining efficient space utilization. The curved surface allows the back cover to be positioned adjacent to the bracket without creating harmful sharp edges.

AI summary
A display device can include a display panel, a module cover disposed at a rear of the display panel, a back cover covering the rear of the module cover, and a latch positioned between the module cover and the back cover and coupled to each of the module cover and the back cover. The module cover can include an elongated hole in which the latch is inserted, and a plurality of inner surfaces defining the hole. The plurality of inner surfaces can include a first inner surface disposed at one side in a longitudinal direction of the hole, and a second inner surface disposed opposite to the first inner surface with respect to the latch. The back cover can include a protrusion protruding from the back cover toward the module cover to be coupled to the latch.
