Metal Bracket Display Assembly Reducing Weight and Cost
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display apparatuses are overweight, oversized, and costly due to redundant components that increase material and assembly costs, and complicate the manufacturing process.
Innovation Solution
A display apparatus design that includes a back cover, front frame, display panel, light guide plate, and metal brackets, where the metal brackets secure the light emitting device and optical film, reducing the number of components and using aluminum extrusion for cost-effective and lightweight construction, and a simplified assembly method that integrates these components without the need for complex molds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple redundant components (external back cover, back plate, external front frame, front frame, plastic frame) are used to protect and secure the display apparatus, then the protective function and structural stability are improved, but the overall weight and volume increase
Solution Approach 1:
The patent combines multiple protective components into an integrated frame structure that simultaneously provides protection for both the liquid crystal panel and backlight module. The frame integrates functions previously performed by separate external back cover, back plate, external front frame, and plastic frame into a unified structural element, reducing total component count and weight while maintaining protective reliability.
Solution Approach 2:
The frame structure is designed to perform multiple functions simultaneously: it protects the liquid crystal panel, secures the backlight module, provides structural support, and enables heat dissipation. This multi-functional design eliminates the need for separate dedicated components for each function, reducing overall weight and complexity.
2Reliability
If multiple redundant components are used to protect and secure the display apparatus, then the protective function is improved, but the material and assembling costs increase
Solution Approach 1:
By merging multiple protective components into a single integrated frame structure, the patent reduces the number of assembly operations required. Instead of separately assembling external back cover, back plate, external front frame, and plastic frame, the integrated frame is installed as a unified component, significantly reducing assembly time and labor costs.
Solution Approach 2:
The frame is designed with modular segments that can be manufactured separately using cost-effective processes and then assembled into the final structure. This segmentation allows for optimized manufacturing of individual parts while maintaining the benefits of integration, reducing both material and assembling costs.
3Reliability
If a plastic frame is used to secure the liquid crystal panel and light guide plate, then the securing function is improved, but the manufacturing cost increases due to high mold costs
Solution Approach 1:
The patent replaces the expensive plastic frame (which requires costly injection molding molds) with a metal frame structure that can be manufactured using more cost-effective processes such as extrusion or bending. This substitution maintains the securing function while significantly reducing tooling and manufacturing costs.
Solution Approach 2:
The invention changes the material parameter from plastic to metal, which fundamentally alters the manufacturing process and cost structure. Metal frames can be produced using lower-cost fabrication methods compared to injection molding, eliminating the need for expensive molds while maintaining structural integrity and securing functionality.
4Stability of the object's composition
If conventional components and structures are used, then the structural stability is maintained, but the overall thickness and volume increase
Solution Approach 1:
The patent employs thin film structures and optimized frame designs that provide adequate structural stability with minimal thickness. The frame structure is engineered to achieve maximum strength-to-thickness ratio, maintaining structural integrity while minimizing the overall volume and thickness of the display apparatus.
