Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connecting structures in liquid crystal display backlights decrease production yield and increase maintenance difficulties due to poor assembly and disassembly efficiency.
Innovation Solution
A backlight rubber-iron structure comprising a back plate with recesses and connecting holes, and a rubber frame with integrated connectors and blockers, forming a nested structure that enhances the engaging force between the back plate and rubber frame, eliminating the need for fastening and preventing deformation during disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional connecting structures are used in backlight products, then the structure is simple to manufacture, but the assembly and disassembly efficiency is low, decreasing production yield
Solution Approach 1:
The patent applies nesting by placing the rubber frame inside the back plate, with the rubber frame body located in the backlight assembly receiving groove and the blocker nested within the recess of the back plate. This nested configuration creates a compact integrated structure that improves assembly efficiency while maintaining manufacturability
Solution Approach 2:
The patent combines multiple components into an integrated structure where the rubber frame body, connector, and blocker are merged into a single rubber frame assembly. This merging of components simplifies the assembly process, improves disassembly efficiency, and increases production yield by reducing the number of separate parts to be assembled
2Ease of repair
If traditional connecting structures are used in backlight products, then the manufacturing process is simple, but the maintenance difficulty increases
Solution Approach 1:
The patent segments the connecting structure into distinct functional elements: the rubber frame body for positioning, the connector for electrical connection, and the blocker for mechanical engagement. This segmentation allows for easier maintenance and repair of individual components while maintaining an integrated overall structure
3Stability of the object's composition
If the engaging force between back plate and rubber frame is insufficient, then the assembly is easy to manufacture, but the structure is prone to deformation during disassembly
Solution Approach 1:
The patent employs curved surfaces in the design of the recess and blocking surface, where the blocker abuts against the curved blocking surface at the bottom of the recess. This curved contact geometry increases the engaging force between the back plate and rubber frame, preventing deformation during disassembly while maintaining ease of manufacture
Solution Approach 2:
The patent incorporates a blocking surface at the bottom of the recess that preliminarily engages the blocker to prevent deformation before the actual disassembly action occurs. This preliminary engagement ensures structural stability during the disassembly process without complicating the manufacturing process

AI summary
A backlight rubber-iron structure and a method of manufacturing the same, a backlight and a display device are disclosed. The backlight rubber-iron structure includes a back plate and a rubber frame. The back plate has a bottom plate and a plurality of folded edges. A plurality of recesses is provided at joints of the bottom plate and the folded edges. Each recess is provided with a connecting hole and a blocking surface. The rubber frame includes a rubber frame body, a connector corresponding to the connecting hole in a one-to-one manner and a blocker corresponding to the recess in a one-to-one manner. The rubber frame body, the connector and the blocker have an integrated structure. The rubber frame body is in the backlight assembly receiving groove. Each blocker is in the corresponding recess and is clamped with the recess by abutting the blocking surface at the bottom of the recess.
