Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices, particularly liquid crystal display devices, suffer from poor structural stability due to viscous connections like water glue or double-sided adhesive, leading to dislocation and potential destruction under external forces during transportation.
Innovation Solution
A display device design featuring a frame and backplate connected via a connector system, including holes and screws, which prevents relative movement and ensures stable connection, eliminating the need for a viscous connection layer, thereby enhancing structural stability and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a viscous connection layer (water glue or double-sided adhesive) is used to connect the frame and backplate, then the assembling of the display device can be realized, but the stability of the connection is poor and dislocation easily occurs
Solution Approach 1:
The patent replaces the chemical bonding mechanism (viscous connection layer) with a mechanical fastening system (connector with holes and screws). The connector includes a first hole in the backplate and a second hole in the frame, through which screws pass to create a rigid mechanical connection, eliminating the reliance on adhesive stability.
Solution Approach 2:
The patent introduces a connector as an intermediary component between the frame and backplate. This connector serves as a mediator that provides a stable connection structure, with the screw acting as the fastening element that passes through both the first hole (in backplate) and second hole (in frame) to secure the two components together.
2Ease of manufacture
If a viscous connection layer is used between the frame and backplate, then connection can be achieved, but the connection is easily broken by external force during transportation
Solution Approach 1:
The patent replaces the weak chemical bond (adhesive) with a strong mechanical fastening system. The screw-connector assembly creates a rigid connection that can withstand external forces during transportation, as the mechanical interlocking through the holes provides superior strength compared to viscous bonding.
Solution Approach 2:
The patent employs a screw thread structure (implicitly curved/interlocking geometry) that provides progressive engagement and distribution of external forces along the threaded path, enhancing the connection's resistance to transportation forces compared to a flat adhesive layer.
3Reliability
If a connector system with holes and screws is used to connect the frame and backplate, then structural stability and reliability are improved, but the device complexity increases
Solution Approach 1:
The patent segments the connection function into distinct components: the connector body with a first hole (in backplate), the frame with a second hole, and the screw as the fastening element. This segmentation allows each component to perform its specific function while collectively providing a stable connection, making the complex task of achieving reliable mechanical fastening manageable through modular design.
4Ease of manufacture
If a viscous connection layer is used between the frame and backplate, then assembly can be performed, but the display device structure becomes thicker
Solution Approach 1:
The patent replaces the thick viscous connection layer with a thin mechanical fastening system. The connector and screw assembly requires minimal space compared to a substantial adhesive layer, thereby reducing the overall thickness of the display device while maintaining assembly capability through the hole-and-screw mechanism.
Data Source
AI summary
A display device is disclosed. The display device comprises a frame used for accommodating edges of a display panel, and a backplate that is arranged on a back side of the display panel, wherein the backplate contacts the frame and is connected with the frame through a connector. The backplate and the frame can be connected with each other stably by the connector, so that the display device has a stable structure, and the reliability of the display device can be effectively improved.
