Solution Overview
Problem
Existing display apparatuses face challenges in reducing the number of components, manufacturing process steps, and thickness, while also mitigating component deformation due to screw fastening methods.
Innovation Solution
The display apparatus integrates a heat sink plate, guide holder, and core plate into a single component made of identical material, using a snap-fit structure to eliminate screw fastening and reduce component count, deformation, and thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate components (heat sink plate, guide holder, core plate) are used with screw fastening, then structural stability and reliability are improved, but device complexity and number of components increase
Solution Approach 1:
The patent combines the heat sink plate, guide holder, and core plate into a single integrated holder member that performs all three functions simultaneously. This merging eliminates the need for multiple separate components and their associated fastening mechanisms, thereby reducing device complexity while maintaining structural stability through the unified design.
Solution Approach 2:
The integrated holder member serves multiple functions: it acts as a heat sink for thermal management, a guide holder for positioning, and a core plate for structural support. This multi-functional design allows a single component to replace three separate components, reducing overall device complexity without compromising reliability.
2Strength
If multiple separate components are assembled using screw fastening, then connection strength is improved, but manufacturing process complexity and time increase
Solution Approach 1:
By merging multiple components into a single integrated holder member, the patent eliminates the need for screw fastening operations between separate parts. This reduces manufacturing process complexity and assembly time while maintaining connection strength through the inherent structural integrity of the integrated design.
3Reliability
If traditional multi-component structure with screw fastening is used, then assembly reliability is improved, but device thickness and bezel size increase
Solution Approach 1:
The integration of multiple components into a single holder member eliminates the need for additional thickness required for multiple layers and fastening mechanisms. This unified structure reduces overall device thickness and bezel size while maintaining assembly reliability through the cohesive design.
4Reliability
If screw fastening method is used to assemble components, then connection reliability is improved, but component deformation occurs
Solution Approach 1:
By combining multiple components into a single integrated holder member, the patent eliminates the screw fastening process entirely. This avoids the application of clamping forces that cause component deformation, thereby maintaining manufacturing precision and component integrity while ensuring connection reliability through the integrated structure.

AI summary
A display apparatus can include a display panel, a front cover member positioned on a front side of the display panel, a guide holder positioned on a rear side of the display panel and accommodating a source printed circuit board connected to the display panel, a control printed circuit board positioned on a board supporting block formed in the guide holder and connected to the source printed circuit board, a back cover member positioned on a rear side of the guide holder and enclosing the source printed circuit board and the control printed circuit board, and a holder member positioned on the guide holder and the back cover member and coupling the guide holder and the back cover member, thereby reducing the total number of components, streamlining the manufacturing process, mitigating component deformation, and reducing the thickness and bezel size.
