Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for assembling liquid crystal display panels are complex, time-consuming, and prone to damaging electrical components due to manual handling and excessive force, leading to increased production costs and risk of component damage.
Innovation Solution
A method involving a backlight unit, a circuit board, and an elastic part with varying cross-sectional areas, where the elastic part is placed between the circuit board and the frame to secure the board to the unit, reducing manual contact and providing electromagnetic protection, thus simplifying the assembly process and reducing production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual assembly method is used to mount circuit board on backlight unit, then assembly flexibility is maintained, but assembly time increases and risk of component damage increases
Solution Approach 1:
An elastic component is introduced as an intermediary between the circuit board and the backlight unit. This elastic component facilitates the connection while reducing direct manual handling of the circuit board, thereby decreasing assembly time and minimizing the risk of component damage during assembly operations.
2Reliability
If frame is used to cover and protect circuit board and backlight unit, then protection is provided, but assembly complexity increases
Solution Approach 1:
The frame structure is merged with the elastic component and mounting mechanism into an integrated assembly. This combination provides protection for the circuit board and backlight unit while simplifying the overall assembly process, as the protective frame simultaneously serves as part of the mounting structure.
3Ease of manufacture
If elastic part is arranged between circuit board and frame, then assembly process is simplified, but additional component is required
Solution Approach 1:
The elastic component is designed to perform multiple functions simultaneously: it provides mechanical connection between the circuit board and backlight unit, offers protection during assembly and disassembly, and enables simplified assembly procedures. This multi-functionality justifies the addition of the component by eliminating the need for separate mounting and protective elements.

Function Achieved in This Case
The solution simplifies the assembly process, decreases assembly time, reduces product damage, and provides electromagnetic protection by using the elastic part to secure the circuit board to the backlight unit, thereby lowering production costs and minimizing manual contact.
Implementation Method 1
elasticity of the elastic part may press and secure the circuit board to the backlight unit
Implementation Method 2
since the elastic part is electrically connected to the ground position of the circuit board, it can directly contact with the frame and provide electromagnetic protection

AI summary
A liquid crystal display module includes a backlight unit, a circuit board, a frame and at least one elastic part. The circuit board is disposed on one surface of the backlight unit. The frame covers over the circuit board. Furthermore, the elastic part is positioned between the circuit board and the frame. Before assembling, the elastic parts have a plurality of continuous cross-sections along with a perpendicular direction of the surface of the backlight unit and the continuous cross-sections have different area values.
