Modular Back Frame Segmentation for Display Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display devices have unstable back frames due to direct positioning without secure fixation, leading to high material and manufacturing costs, and the need for large, complex molds for different sizes.
Innovation Solution
A back frame design using primary assembling pieces with joint sections and positioning sections that securely attach to a back panel, allowing for easy removal and stabilization, while reducing material usage and mold complexity by using shared molds for different sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a unitary back frame is used for different sizes, then manufacturing complexity increases, but production efficiency remains low
Solution Approach 1:
The back frame is divided into multiple modular segments (first back frame segment, second back frame segment, third back frame segment) that can be independently manufactured and then assembled. This segmentation allows different size configurations to be achieved by combining different numbers and arrangements of standard segments, eliminating the need for complex large-sized molds while maintaining size adaptability across different display device specifications.
2Strength
If a unitary back frame is used, then material consumption increases, but structural integrity is maintained
Solution Approach 1:
The back frame is segmented into multiple independent parts (first, second, and third back frame segments) that are connected through joining structures. This segmentation reduces material consumption by eliminating the need for a single large continuous structure, while the joining structures (including positioning sections and fixing mechanisms) ensure that the assembled segments achieve the required structural integrity and stability.
Solution Approach 2:
The modular back frame segments are designed to nest or interconnect with each other through positioning sections and joining structures. This nested arrangement allows efficient space utilization and reduces overall material requirements while maintaining the structural strength needed to support the display device components.
3Ease of operation
If the back frame is directly positioned without secure fixation, then assembly ease increases, but device stability deteriorates
Solution Approach 1:
The back frame segments are provided with pre-formed positioning sections that include positioning protrusions and corresponding positioning recesses. These positioning features are prepared in advance during manufacturing, enabling the segments to be easily aligned and connected during assembly. This preliminary preparation maintains assembly ease while ensuring stable and secure fixation when the segments are joined together.
Solution Approach 2:
Joining structures serve as intermediaries between the back frame segments, including positioning sections with protrusions and recesses, and fixing structures with fastening mechanisms. These intermediary elements facilitate easy assembly by guiding the connection process while simultaneously providing secure fixation to ensure device stability, bridging the gap between ease of operation and reliability.
