Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of multiple lamp boards on the splicing sides of a backplane in large-size backlight modules is inconvenient due to limitations in the printing ability of the lamp boards, making it difficult to assemble and fix them securely.
Innovation Solution
A backlight module design that includes a fastener with a first and second connecting structure, and limit portions to securely attach and restrict the movement of adjacent lamp boards on the backplane, reducing the number of fasteners needed and simplifying the assembly process by using a bolt and threaded hole configuration.

Engineering Contradiction Analysis
1Area of stationary object
If multiple small-size lamp boards are spliced to manufacture large-size backlight modules, then the size of the backlight module can be increased, but the assembly convenience on the splicing side deteriorates
Solution Approach 1:
The backlight module is divided into multiple splicable lamp boards, allowing the overall size to be increased by combining several smaller units. This segmentation enables modular assembly while maintaining manufacturing feasibility through standardized splicing interfaces between adjacent lamp boards.
Solution Approach 2:
Adjacent lamp boards are merged through splicing to form a large-size backlight module. The splicing structure combines multiple independent lamp boards into a unified assembly, achieving the desired large area while maintaining the benefits of modular construction.
2Reliability
If traditional fastening methods are used to fix multiple lamp boards on the backplane, then the lamp boards can be secured, but the number of fasteners and assembly steps increase
Solution Approach 1:
The connecting structure merges the functions of multiple fasteners into a single integrated component. The fastener simultaneously connects adjacent lamp boards and secures them to the backplane, reducing the total number of fastening elements required while maintaining reliable fixation.
Solution Approach 2:
The fastener is designed with multi-functionality, serving both to connect adjacent lamp boards together and to secure the assembly to the backplane. This universal fastening solution eliminates the need for separate connecting and securing mechanisms, simplifying the overall assembly.
3Area of stationary object
If lamp boards are spliced to form large-size backlight modules, then the backlight module area can be increased, but the assembly process becomes more complex
Solution Approach 1:
The large backlight module is segmented into smaller, standardized lamp boards that can be manufactured independently and then spliced together. This segmentation simplifies the manufacturing process by allowing parallel production of modular units while achieving large overall area through assembly.
Solution Approach 2:
Multiple lamp boards are merged through standardized splicing interfaces to form the complete backlight module. The splicing structure combines modular units in a systematic way that maintains manufacturing simplicity while achieving the desired large area configuration.
