Solution Overview

Problem

Existing display devices face issues with sagging of components due to inadequate structural support, particularly in ultra-thin designs, and require improved integration of frames and covers to enhance stability and minimize thickness.

Innovation Solution

A display device design incorporating a plate, frame, and mount plate with interlocking features such as fixing parts and coupling parts, along with adhesive members and ribs to provide structural integrity and minimize sagging, while using injection molded products for certain components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If the display device uses an ultra-thin design, then the thickness is reduced, but structural stability deteriorates causing sagging of components

Engineering Contradiction:
ImprovethicknessVSAvoidstructural stability
Core Design Contradiction:
Length of moving objectVSStability of the object's composition

Solution Approach 1:

The support structure is divided into multiple functional components: a frame providing peripheral support, a mount plate for centralized mounting, and multiple ribs extending from the frame to the mount plate. This segmentation distributes structural support across multiple elements rather than relying on a single thick component, maintaining thinness while improving stability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a multi-dimensional support architecture where ribs extend in the thickness direction from the frame to the mount plate, creating a three-dimensional structural framework. This dimensional approach provides structural reinforcement without increasing the planar footprint, enabling thinness while maintaining stability.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Stability of the object's composition

If multiple components (plate, frame, mount plate) are integrated, then structural stability is improved, but device complexity increases

Engineering Contradiction:
Improvestructural stabilityVSAvoidcomponent integration
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The frame and mount plate are integrated into a unified structural assembly where the ribs connect the two components, merging their support functions. This integration creates a coordinated structural system that provides enhanced stability while reducing the number of separate parts compared to fully discrete component designs.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The frame serves multiple functions: providing peripheral support, anchoring the ribs, and forming part of the overall structural framework. The ribs themselves serve dual purposes by both supporting the structure and defining the spatial relationship between the frame and mount plate, reducing the need for additional dedicated components.

Inventive Principle:
Principle #6Universality (Multi-functionality)
