Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing display devices have a complex backlight assembly configuration that increases weight and volume, necessitating a simplified structure to reduce component costs and streamline assembly.
Innovation Solution
A display device with a simplified structure featuring a set cover composed of plastic, including a rear cover part and side cover part with integrally formed shapes, which covers the backlight assembly and supports the display panel, along with a guide panel and a light source housing, to reduce component count and enhance assembly efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the backlight assembly uses a complex configuration with separate cover parts, then the structural strength and protection are improved, but the device weight and volume increase
Solution Approach 1:
The patent combines multiple separate cover parts (rear cover and side cover) into a single integrated set cover component. This merging reduces the total number of parts, decreases device weight, and simplifies the overall structure while maintaining the protective function through the unified design that covers both rear and side surfaces of the backlight assembly.
2Reliability
If multiple separate cover parts are used, then the coverage and protection are improved, but the number of components and assembly complexity increase
Solution Approach 1:
The set cover integrates the rear cover and side cover into one unified component, reducing the number of parts that need to be manufactured, inventoried, and assembled. This single component provides comprehensive coverage for both rear and side surfaces, eliminating the need for separate assembly steps while maintaining full protective coverage.
Solution Approach 2:
The integrated set cover performs multiple functions simultaneously: it protects the rear surface, protects the side surface, provides structural support, and serves as a mounting surface for wall-mount coupling holes. This multi-functionality in a single component reduces overall device complexity while maintaining comprehensive protection.
3Manufacturing precision
If separate cover parts are used, then the manufacturing precision of each part can be optimized, but the component cost and assembly time increase
Solution Approach 1:
By combining the rear cover and side cover into a single set cover component, the patent reduces the total number of manufacturing operations, inventory requirements, and assembly steps. This integration lowers component costs despite maintaining manufacturing precision through the use of molding techniques suitable for plastic materials.
Solution Approach 2:
The patent transitions from metal or multi-part construction to a single plastic component, changing the material parameter to enable cost-effective manufacturing through injection molding or similar processes. This parameter change allows for precise geometry to be achieved during molding while reducing overall component cost.
