Solution Overview
Problem
Existing flat display devices have increased thickness and weight due to thick metallic frames and require complex assembly processes for fixing circuit boards, which hinder their compactness and ease of installation.
Innovation Solution
A display device with a fixing plate on the rear surface of the display module, allowing the circuit board to be inserted and fixed through elastic deformation, eliminating the need for separate fastening members and using non-conductive, lightweight materials like plastic for the fixing plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a thick metallic frame is used to support the circuit board, then the structural strength and stability are improved, but the thickness and weight of the display device increase
Solution Approach 1:
The patent changes the material parameter from metal to plastic for the fixing plate, and changes the thickness parameter from thick to thin (1-3mm), thereby reducing weight while maintaining sufficient structural strength through optimized design
Solution Approach 2:
The patent separates the support function into two parts: the display module housing provides primary structural support, while the thin fixing plate provides localized support for the circuit board, eliminating the need for a thick overall frame structure
2Reliability
If a fixing member such as a screw is used to attach the circuit board to the frame, then the reliability of the connection is improved, but the assembly process becomes complicated
Solution Approach 1:
The patent replaces the mechanical screw-fastening system with an elastic deformation-based fixing mechanism, where the fixing plate bends elastically to clamp the circuit board, eliminating the need for separate fastening members and simplifying assembly
Solution Approach 2:
The fixing plate performs both the support function and the fastening function simultaneously through its elastic deformation capability, making the system self-sufficient and eliminating the need for additional fixing members
3Stability of the object's composition
If a metallic frame structure is used, then the structural stability is improved, but the overall device weight increases
Solution Approach 1:
The patent changes the material parameter from metal to plastic for the fixing plate, reducing density and weight while maintaining sufficient structural stability through optimized geometric design and elastic properties
Solution Approach 2:
The patent uses a thin, flexible plastic fixing plate that can elastically deform to provide stable support and secure attachment, replacing rigid metallic structures with flexible thin-film structures
