Backlight Module Positioning Assembly for Panel Size Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing manufacturing process for liquid crystal display products requires multiple molds for different backlight modules, leading to high costs due to varying panel sizes and resolutions, making it inefficient to use display panels with different active areas of the same nominal dimension.
Innovation Solution
A panel positioning assembly with detachable positioners on a side frame, allowing for the same backlight module to accommodate different panel sizes by exchanging positioners, rather than replacing the module, thus reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If different backlight modules are designed for different panel sizes, then panel positioning accuracy is improved, but manufacturing cost increases due to multiple molds
Solution Approach 1:
The backlight module is segmented into a standard housing and detachable positioners. The positioners are separate components that can be removed and exchanged, allowing the same housing to accommodate different panel sizes. This segmentation enables one mold to produce the housing while separate positioners are added for different panel configurations, reducing the need for multiple complete module molds.
Solution Approach 2:
The standard housing of the backlight module is designed with universal compatibility to accommodate multiple panel sizes through the exchange of positioners. A single housing design serves multiple functions by working with different positioner configurations, eliminating the need for dedicated molds for each panel size and reducing overall manufacturing costs.
2Adaptability or versatility
If multiple backlight modules are manufactured for different panel sizes, then adaptability to various panel dimensions is improved, but device complexity increases
Solution Approach 1:
The backlight module is divided into a standardized housing and interchangeable positioners. This segmentation allows the housing to remain uniform across different panel sizes while only the positioners need to be changed, simplifying the overall system architecture compared to having completely different modules for each panel size.
Solution Approach 2:
A single universal housing design is created that can accommodate multiple panel sizes through the exchange of positioners. This universal design reduces device complexity by eliminating the need for multiple specialized module designs, while still providing adaptability to various panel dimensions.
3Ease of manufacture
If detachable positioners are used instead of fixed module designs, then manufacturing cost is reduced, but assembly complexity increases
Solution Approach 1:
The positioners are designed as detachable segments that can be easily separated from the housing. This segmentation enables cost-effective manufacturing through a single housing mold while allowing straightforward assembly and disassembly of positioners, balancing the trade-off between manufacturing savings and assembly complexity.
Solution Approach 2:
The positioners are designed with dynamic, detachable connections to the housing rather than fixed permanent attachments. This dynamic design allows for easy exchange of positioners to accommodate different panel sizes, reducing manufacturing costs through standardized housing molds while maintaining simple assembly procedures through standardized connection interfaces.
