Elastically Deformable Frame with Arc-Shaped Structures for Backlight Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing backlight sources for liquid crystal displays have inefficient assembly processes due to a large number of engagement points between the frame and the back plate, leading to deformation, increased manufacturing costs, and a high risk of breaking the glass screen during assembly or disassembly.
Innovation Solution
A frame with a long border and two short borders featuring arc-shaped structures and uniformly distributed connection members is designed to simplify the assembly and disassembly process by allowing elastic deformation to securely engage with a rectangular back plate, reducing the number of connection points and stabilizing the fixation of components like the reflector plate, light guide plate, and optical film.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a large number of engagement points are used between the frame and back plate, then the fixation stability is improved, but the assembly complexity and time increase significantly
Solution Approach 1:
The frame is divided into four independent elastic arms, each with its own engagement point. This segmentation allows each arm to independently deform and engage with the back plate, providing stable fixation while simplifying the overall assembly process compared to a rigid multi-point connection system
Solution Approach 2:
The frame transitions from a rigid structure to an elastic structure by changing the material parameter (introducing elasticity). This allows the frame to deform during assembly and engagement, reducing assembly complexity while maintaining fixation stability through elastic recovery
2Stability of the object's composition

3Stability of the object's composition
If a large number of engagement points are used between the frame and back plate, then the fixation stability is improved, but the risk of glass screen breakage increases
Solution Approach 1:
The frame transitions from a rigid structure to an elastic structure by changing the material parameter (introducing elasticity). This allows the frame to deform during assembly and engagement, reducing assembly complexity while maintaining fixation stability through elastic recovery
Solution Approach 2:
The elastic arms provide a cushioning effect during assembly by deforming to absorb engagement forces. This beforehand cushioning prevents sudden force transmission to the glass screen, reducing the risk of breakage while maintaining stable fixation
4Length of stationary object
If the frame has a small thickness, then the overall size is reduced, but the deformation risk during assembly increases
Solution Approach 1:
The frame transitions from a rigid structure to an elastic structure by changing the material parameter (introducing elasticity). This allows the frame to deform during assembly and engagement, reducing assembly complexity while maintaining fixation stability through elastic recovery
Solution Approach 2:
The frame is designed to be dynamically deformable rather than statically rigid. The elastic arms can bend and deform during assembly to accommodate engagement forces, then return to their original shape to provide stable fixation, preventing permanent deformation

AI summary
The present disclosure discloses a frame for fixating a component of a backlight source to a rectangular back plate. A long border of the frame has a first arc-shaped structure configured such that a central position of the long border is bent inwards relative to two ends of the long border. Each short border of the frame has a second arc-shaped structure configured such that two ends of the each short border are bent inwards relative to a central position of the each short border. First connection members for engagement with the back plate are disposed at the central position of the long border, and positions, close to the two ends, of the long border, respectively, and second connection members for engagement with the back plate are disposed at the central position of each short border, and positions, close to the two ends, of the each short border, respectively.
