Display Device Chassis Frame Integration for Slim Structural Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LCD display devices face challenges in achieving a balance between strength and slim size due to the structural limitations of the mold frame and chassis, which affect the reinforcement and thickness of the backlight unit.
Innovation Solution
The display device incorporates a liquid crystal panel, a backlight assembly, and a chassis with a frame that receives the panel and assembly, where the chassis is inserted into the frame to enhance strength and maintain a slim size, utilizing a C-shaped support structure and insert injection molding to reinforce the mold frame without increasing thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the mold frame and chassis are manufactured separately and fitted together, then the structural strength is improved, but the device thickness increases
Solution Approach 1:
The patent merges the mold frame and chassis into a single integrated component. The receiving device comprises a single piece that performs both functions: receiving the liquid crystal panel and reinforcing structural strength. This eliminates the need for separate manufacturing and assembly of mold frame and chassis, thereby reducing overall device thickness while maintaining structural integrity.
Solution Approach 2:
The receiving device is designed as a multi-functional component that simultaneously serves as both the mold frame (receiving and positioning the liquid crystal panel) and the chassis (providing structural reinforcement). This universal design allows a single component to fulfill multiple roles, eliminating the need for additional thickness to accommodate separate structural elements.
2Reliability
If the mold frame is reinforced to improve strength, then the structural durability is improved, but the manufacturing complexity increases
Solution Approach 1:
By combining the mold frame and chassis functions into a single receiving device, the patent simplifies the manufacturing process. Instead of manufacturing two separate components and assembling them, only one component needs to be manufactured, thereby reducing manufacturing complexity while maintaining the structural durability benefits of reinforcement.
3Strength
If the chassis is inserted into the frame, then the structural strength is improved, but the device complexity increases
Solution Approach 1:
The patent eliminates the complex insertion structure by merging the chassis and frame into a single integrated receiving device. This unified design provides structural strength without requiring complex multi-component assembly structures, thereby reducing overall device complexity while maintaining reinforcement benefits.
