Horizontal Display Hinge Structure With Fewer Screws
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display device hinge assemblies are complex, require a large number of components, and are costly due to the need for a bottom board and multiple screws, resulting in high material costs and low yield rates during assembly.
Innovation Solution
A horizontal type display device design featuring a base unit, a vertical support structure, a horizontal support structure connected to the display screen, and a hinge structure integrated within the display screen, allowing for adjustable viewing angles without the need for a bottom board or multiple screws, using a hinge unit that connects the display screen to the horizontal support structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a bottom board and multiple screws are used to connect the connecting base to the base of the LCD, then the structural stability is improved, but the device complexity and material cost increase
Solution Approach 1:
The patent integrates the bottom board function directly into the connecting base by forming a reinforcing rib that extends from the connecting base to provide bottom support. This merging of functions eliminates the need for a separate bottom board and reduces the number of components while maintaining structural stability.
Solution Approach 2:
The connecting base is designed to serve multiple functions: it provides the primary connection structure, incorporates the reinforcing rib for bottom support, and integrates the locking element mechanism. This multi-functionality reduces the overall component count and simplifies the assembly structure.
2Stability of the object's composition
If a bottom board and multiple screws are used to connect the connecting base to the base of the LCD, then the structural stability is improved, but the manufacturing cost increases
Solution Approach 1:
The bottom board function is merged into the connecting base through the reinforcing rib structure, eliminating the need for separate components and reducing material costs while maintaining structural integrity.
Solution Approach 2:
The patent extracts and eliminates unnecessary components (bottom board and multiple screws) by integrating their functions into the connecting base and locking element, thereby reducing material costs and simplifying manufacturing.
3Strength
If a bottom board and multiple screws are used for assembly, then the connection strength is improved, but the assembly yield rate decreases due to large tolerances
Solution Approach 1:
The locking element is designed with a dynamic structure that includes a locking portion and a pressing portion. The pressing portion elastically presses the locking portion into the ear part, providing automatic locking and adjustment capabilities that accommodate tolerance variations and improve assembly yield.
Solution Approach 2:
The locking element automatically locks the rotating element to the connecting base through its elastic pressing mechanism, eliminating the need for precise manual alignment and reducing assembly complexity, thereby improving yield rate.

AI summary
A horizontal type display device includes a base unit, a first support unit, a display unit, a second support unit and a hinge unit. The base unit includes a base body. The first support unit includes a vertical support structure vertically disposed on the base body. The display unit includes a display screen disposed above the base body and beside the vertical support structure. The second support unit includes a horizontal support structure horizontally connected between the vertical support structure and the display screen. The horizontal support structure has a first end portion inserted and fixed in the vertical support structure. The hinge unit includes a hinge structure disposed inside the display screen and connected to a second end portion of the horizontal support structure. The view angle of the display screen can be adjustable through the hinge structure that is connected to the display screen.
