Multifunctional Plastic Frame for Backlight Module Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional backlight module assembly process is inefficient due to complex operations and high part counts, leading to potential losses and degraded product quality from separate fixing of plastic and front frames using catches or screws.
Innovation Solution
A multifunctional plastic frame with movably connected covers that can be buckled to the frame body using catches or screws, reducing the number of parts and enabling quick assembly by integrating the frame and covers through injection molding, eliminating the need for a separate front frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the plastic frame and front frame are fixed respectively using catches or screws, then the structural stability is ensured, but the assembly process becomes complex and efficiency decreases
Solution Approach 1:
The patent combines the plastic frame and front frame into a single integrated frame structure. The front frame is formed as an extension of the plastic frame, creating one unified component that performs both support and shielding functions. This eliminates the need for separate fixing operations and reduces the number of fasteners required, thereby improving assembly efficiency while maintaining structural stability.
Solution Approach 2:
The integrated frame structure serves multiple functions simultaneously: it provides structural support, shields the LCD panel, and acts as a single assembly unit for mounting. By designing the front frame as part of the plastic frame structure, the system achieves multi-functionality with a single component, reducing complexity in the assembly process.
2Reliability
If the plastic frame and front frame are fixed respectively using catches or screws, then the structural stability is ensured, but the number of parts increases leading to part loss and quality degradation
Solution Approach 1:
The patent merges the plastic frame and front frame into one integrated component structure. The front frame is designed as a continuous extension of the plastic frame, forming a single part that eliminates the need for separate fastening elements between these two components. This reduction in part count minimizes the risk of part loss during assembly and improves overall product quality.
3Reliability
If separate fixing methods are used for plastic frame and front frame, then the structural stability is ensured, but the operation complexity and time increase
Solution Approach 1:
The patent integrates the plastic frame and front frame into a single structure that can be assembled as one unit. The LCD panel is mounted to the integrated frame using a single set of fastening operations, eliminating the need for separate fixing procedures. This simplifies the assembly process, reduces operational complexity, and decreases assembly time while maintaining structural integrity.

AI summary
A multifunctional plastic frame and a backlight module are disclosed. The multifunctional plastic frame comprises a frame body for supporting an LCD panel and covers movably connected with outer edges of the frame body. The covers are turned over along the outer edges of the frame body to press against edges of the LCD panel and to be buckled to the frame body. According to the present disclosure, the number of parts and consequently the cost are reduced; and the backlight module can be assembled quickly in a convenient way, which is favorable for improving the assembling efficiency of the backlight module.
