Diffusion Plate Support Frame Buffering for Backlight Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The diffusion plate in direct-type backlight modules bends and deforms under gravity, requiring a support frame to prevent damage and ensure proper alignment, but existing solutions lack effective buffering to prevent scratching and simplify assembly/disassembly.
Innovation Solution
A diffusion plate support frame with a bottom plate and support portions featuring a first buffer structure and support pin, which includes additional buffer structures and auxiliary support plates, designed to absorb pressure and prevent scratching, and a clamping mechanism for secure attachment without complex hooks or screws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a support frame is added to prevent diffusion plate deformation, then the diffusion plate is protected from bending under gravity, but the structure becomes more complex and assembly/disassembly becomes difficult
Solution Approach 1:
The support frame is divided into a bottom plate and multiple independent support portions, each with its own buffer structure. This segmentation allows each component to perform its specific function independently while simplifying the overall assembly and disassembly process.
Solution Approach 2:
Buffer structures are pre-installed between the support pin and bottom plate to provide cushioning before any potential damage occurs. This beforehand cushioning prevents scratching of the diffusion plate while maintaining a simple support frame structure without complex locking mechanisms.
2Reliability
If traditional locking mechanisms (screws or double-sided tape) are used to secure the support frame, then the attachment is secure, but the assembly process becomes complex and costly
Solution Approach 1:
The support frame utilizes the diffusion plate's own weight and the buffer structure's elastic deformation to achieve self-securing. When assembled, the support pin compresses the buffer structure, creating friction and elastic retention that holds the diffusion plate in place without requiring additional locking mechanisms.
Solution Approach 2:
The buffer structure serves as an intermediary element between the support pin and bottom plate, providing both mechanical support and secure attachment through its elastic properties. This intermediary component eliminates the need for screws or double-sided tape while maintaining reliable attachment.
3Device complexity
If the support pin directly contacts the bottom plate, then the structure is simpler, but the diffusion plate may be scratched under pressure
Solution Approach 1:
A buffer structure is positioned between the support pin and bottom plate to provide cushioning before any harmful contact can occur. This buffer absorbs pressure and prevents the support pin from directly contacting and scratching the diffusion plate, while maintaining overall structural simplicity.
Solution Approach 2:
The buffer structure acts as an intermediary protective layer between the rigid support pin and the diffusion plate. This intermediary component absorbs mechanical stress and prevents direct harmful contact, eliminating scratching risks without requiring complex protective mechanisms.
