Adapter Brackets for Thin Display Back Panel Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in assembling LCD TVs lies in integrating various components efficiently, particularly in achieving a fixed connection between the first and second back panels without compromising the structural integrity or increasing the thickness, while also accommodating a narrow bezel design.
Innovation Solution
The solution involves a display device configuration where the first and second back panels are fixedly connected using adapter brackets, with the second back panel being smaller in area and made of materials like steel or aluminum, and a composite first back panel with polyethylene layers for enhanced strength, along with an optical component and heat-radiating component, allowing for a thin and narrow bezel design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the first and second back panels are fixedly connected using adapter brackets, then the structural integrity is improved, but the device complexity increases
Solution Approach 1:
The adapter bracket serves as an intermediary component that connects the first back panel and the second back panel. The bracket includes a first connecting portion that connects to the first back panel and a second connecting portion that connects to the second back panel, enabling fixed connection between the two panels while maintaining structural integrity without directly modifying the panels themselves
Solution Approach 2:
The connection system is segmented into separate functional components: the adapter bracket, the first connecting portion, and the second connecting portion. This segmentation allows each component to be optimized independently and simplifies the overall assembly process by dividing the connection function into manageable parts
2Length of stationary object
If the display device is designed with ultra-thin profile, then the aesthetic appearance is improved, but the heat dissipation capability deteriorates
Solution Approach 1:
The adapter bracket is designed with varying local qualities: the first connecting portion has a first thickness while the second connecting portion has a second thickness that is greater than the first thickness. This local variation in thickness allows the bracket to provide enhanced heat dissipation capability at the connection point with the second back panel while maintaining the overall ultra-thin profile of the display device
3Area of stationary object
If the second back panel is made smaller in area, then the narrow bezel design is achieved, but the mounting stability deteriorates
Solution Approach 1:
The adapter bracket is constructed from a composite material or structure that combines materials with different properties. The bracket integrates a first connecting portion and a second connecting portion with different thicknesses and potentially different material compositions, creating a composite structure that provides both the narrow bezel design and the required mounting stability
