Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display devices with integrated frames have a large thickness and visible packaging gaps between the back cover plate and front frame, affecting their appearance and functionality.
Innovation Solution
An outer frame design featuring sub-frames with accommodation grooves for both the liquid crystal module and back cover plate, allowing for edge packaging without visible gaps and eliminating the need for a front frame, thereby reducing thickness and improving aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If an integrated frame structure is used to package the liquid crystal module, then the packaging firmness is improved, but the device thickness increases and visible gaps appear between components
Solution Approach 1:
The frame is divided into multiple independent components: a back frame for packaging the back cover plate, and a front frame for packaging the liquid crystal module. These segmented frames are connected through connecting structures, allowing each frame to perform its specific packaging function independently while maintaining overall structural stability without requiring excessive thickness.
Solution Approach 2:
The front frame is positioned within the space defined by the back frame, creating a nested configuration. The connecting structures integrate the two frames into a unified packaging system that accommodates both the liquid crystal module and back cover plate efficiently, reducing the overall device thickness while maintaining packaging firmness.
2Stability of the object's composition
If an integrated frame structure is used, then the packaging firmness is improved, but visible gaps appear between the back cover plate and front frame affecting appearance
Solution Approach 1:
Connecting structures serve as intermediary elements between the back frame and front frame. These connectors bridge the gap between the two frames, providing both mechanical support for packaging firmness and a design solution that eliminates visible gaps, thereby improving the overall appearance quality of the device.
Solution Approach 2:
The back frame, front frame, and connecting structures are merged into an integrated packaging assembly. This unified structure ensures that the edges of the back cover plate and front frame are aligned and connected without visible gaps, while maintaining the packaging firmness required for structural stability.
3Strength
If a front frame is added to fasten the liquid crystal screen, then the fastening function is improved, but the device thickness increases
Solution Approach 1:
The front frame is designed to perform multiple functions: it packages the liquid crystal module edges, provides fastening capability through integrated fixing structures, and connects to the back frame via connecting structures. By combining these functions into a single component, the need for additional thickness-providing elements is eliminated.
Solution Approach 2:
The connecting structures utilize spatial arrangement in multiple dimensions to connect the back frame and front frame. By optimizing the three-dimensional configuration of these connectors, the design achieves effective fastening capability while minimizing the thickness dimension of the overall device.
