Segmented LCD Frame Assembly for Single-Mold Production
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of conventional LCD modules requires different molds for the front and middle frames due to size and structural differences, leading to increased production costs.
Innovation Solution
The use of segmented pieces for both the front and middle frames with matching fixing and butting structures, including wedge-shaped snags and holes, allows for the same structure to be used for frames of different sizes, reducing the need for multiple molds and simplifying the assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If different molds are used for front frame and middle frame, then the frames can be produced with distinct structures, but production cost increases
Solution Approach 1:
The patent applies universality by designing segmented pieces that can serve multiple functions. The same segmented piece structure is used for both the front frame and middle frame, allowing a single mold design to produce components for both frames. This multi-functional approach eliminates the need for separate molds, reducing production cost while maintaining the ability to create different frame configurations.
Solution Approach 2:
The patent divides the frame structure into segmented pieces that can be independently produced and assembled. By segmenting the frame into modular units with standardized interfaces (fixing structures and butting structures), the same basic segmented piece can be used across different frame types, enabling cost-effective production through a single mold design.
2Ease of manufacture
If different structures are used for front frame and middle frame, then each frame can be optimized for its specific function, but assembly complexity increases
Solution Approach 1:
The frame is divided into segmented pieces with standardized fixing structures and butting structures. This segmentation allows each piece to be optimized for its specific functional requirements while maintaining a unified connection interface, simplifying the overall assembly process despite functional differences between front and middle frames.
Solution Approach 2:
The standardized fixing and butting structures create a universal connection system that works for both front frame and middle frame assembly. This universal interface reduces assembly complexity by providing consistent joining methods across different frame components, even though the frames serve different functions.
3Quantity of substance
If same mold is used for front frame and middle frame, then production cost is reduced, but the structure must be simplified
Solution Approach 1:
By segmenting the frame into modular pieces with standardized connection features, the same mold can produce universal components that are then configured differently for front and middle frames. This segmentation maintains structural adequacy while enabling cost-effective production through mold reuse.
Solution Approach 2:
The segmented pieces incorporate local quality variations through their fixing structures and butting structures, allowing the same basic component design to serve different functional requirements in different frame locations. This enables structure simplification for manufacturing while maintaining functional complexity where needed.

AI summary
The invention provides an LCD module and a frame thereof. The frame comprises a plurality of segmented pieces constituting the frame; the frame comprises a front frame, and a middle frame; the structure of the segmented piece(s) constituting the front frame is the same as that of the segmented piece(s) constituting the middle frame. Because the front frame and the middle frame of the LCD module of the invention are comprised of a plurality of segmented pieces of the same structure, the segmented pieces constituting the front frame can be superposed outside the segmented pieces constituting the middle frame, and then the front frame and middle frame of different sizes can be respectively formed. Thus, because the segmented pieces constituting the front frame and middle frame are of the same structure, the segmented pieces can be produced by only one mold, and the front frame and the middle frame can be produced just by the same mold, thereby saving the production cost. In addition, the segmented pieces can be cut only on one section without singly producing each segmented piece, thereby further reducing the production cost of LCD modules.
