Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional backlight modules for liquid crystal displays require redesigning the fixing bracket to accommodate different light strip distances, leading to high costs and limited versatility due to the need for precise alignment between light sources and quantum bars.
Innovation Solution
A hollow cylindrical fixing bracket with adjustable windows and a support beam that separates light sources from quantum bars, allowing for flexible assembly without modifying the bracket design, and featuring a clamping hook and thread connection for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the fixing bracket is redesigned to accommodate different light strip distances, then the alignment between light sources and quantum bars is improved, but the manufacturing cost increases and versatility decreases
Solution Approach 1:
The fixing bracket is designed with a universal structure that can accommodate different light strip distances without requiring redesign. The bracket includes adjustable positioning features and standardized mounting interfaces that allow it to work with various light strip configurations, thereby improving versatility while maintaining manufacturing precision through consistent design standards.
Solution Approach 2:
The fixing bracket incorporates adjustable and reconfigurable elements that allow it to adapt to different light strip distances dynamically. This includes movable positioning mechanisms and flexible mounting options that enable the same bracket design to be used across multiple product configurations, resolving the contradiction between precision alignment and versatility.
2Manufacturing precision
If the fixing bracket is redesigned for each light strip distance, then the alignment between light sources and quantum bars is improved, but the device complexity and assembly complexity increase
Solution Approach 1:
A single universal fixing bracket design is created that can accommodate multiple light strip distances through built-in adjustment mechanisms. This eliminates the need for multiple specialized bracket designs, thereby reducing device complexity while maintaining the ability to achieve precise alignment between light sources and quantum bars across different configurations.
Solution Approach 2:
The fixing bracket is designed with modular and segmented features that allow independent adjustment of positioning elements. This segmentation enables precise alignment to be achieved through simple reconfiguration of modular components rather than requiring complete redesign of the entire bracket structure, thus reducing design complexity.
3Manufacturing precision
If the fixing bracket is redesigned for each light strip distance, then the alignment between light sources and quantum bars is improved, but the manufacturing cost increases
Solution Approach 1:
The fixing bracket employs a universal design that can be manufactured once and used across multiple product variants with different light strip distances. This standardization significantly reduces manufacturing costs by eliminating the need for multiple specialized bracket production lines, while still achieving precise alignment through the bracket's built-in adjustment and positioning capabilities.
Solution Approach 2:
The fixing bracket design allows for parameter adjustments (such as positioning distances and mounting locations) without changing the fundamental bracket structure. This enables the same manufactured bracket to be configured for different light strip distances, maintaining manufacturing precision while avoiding the costs associated with redesigning and remanufacturing brackets for each configuration.

AI summary
A backlight module comprises a back plate; a side-type light source; a light guide plate disposed on the back plate; and a quantum bar assembled between the light guide and the light source via a fixing bracket. The fixing bracket is a hollow cylinder, and comprises an accommodating space defined in the fixing bracket for installing the quantum bar and the first window faced toward the light guide plate and the second window faced toward the side-type light source and the length of the second window is equal to one of the light strip. A support beam is disposed on the light strip and between the two light sources, and the length of the support beam is less than or same as a width of the second window, and a height of the support beam is not less than a height of the light source, and the light strip is assembled in the second window.
