Backlight Module Outer Frame Locking for Display Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current touch-integrated display products have complex and time-consuming manufacturing processes due to numerous components and structures, leading to high production costs and a high risk of appearance defects.
Innovation Solution
A backlight module design that includes a back plate, transitional frames, and an outer frame, where the light guide plate and outer frame are on the same side of the back plate, with sideward and back lock members for secure connection, simplifying assembly and reducing the need for auxiliary jigs, thereby improving production efficiency and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional separate assembly methods are used for backlight components, then each component can be assembled independently, but the overall assembly process becomes complex and time-consuming requiring multiple auxiliary jigs
Solution Approach 1:
The outer frame is designed to simultaneously support both the light guide plate and the display screen, merging two separate support functions into a single structural component. This integration eliminates the need for separate assembly fixtures and reduces the number of assembly steps, directly addressing the contradiction between assembly simplicity and manufacturing time
2Stability of the object's composition
If multiple separate frames and components are used to ensure structural stability, then the structural integrity is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The outer frame is designed as a multi-functional component that simultaneously serves as a support structure for the light guide plate, a support structure for the display screen, and a structural stabilizer for the entire backlight module. This multi-functionality reduces the total number of components while maintaining structural stability, resolving the contradiction between structural integrity and device complexity
3Manufacturing precision
If traditional assembly methods with multiple auxiliary jigs are used, then precise positioning can be achieved, but the production cost and manufacturing complexity increase
Solution Approach 1:
The outer frame is pre-designed with integrated positioning features and mounting structures that automatically guide the correct placement of the light guide plate and display screen during assembly. This preliminary design of positioning features eliminates the need for external auxiliary jigs while maintaining precise component positioning, resolving the contradiction between manufacturing precision and process simplicity
