Solution Overview

Problem

Existing display devices face challenges in securing rigidity while improving their assembling structure, which affects the overall durability and performance of the display.

Innovation Solution

A display device design featuring a front cover with a hook and a back cover with a latching portion, where the latching portion is formed by rounding the second side wall of the back cover, and a fastening portion with a curved surface, allowing for secure fastening and enhanced rigidity through a combination of structural elements like frames, clips, and fixers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a complex assembling structure is used to improve rigidity, then structural integrity is enhanced, but device complexity increases

Engineering Contradiction:

ImproverigidityVSAvoidassembling structure

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The cover structure is divided into a front cover and a back cover that can be assembled separately. The back cover includes a latching portion that engages with a hook on the front cover, allowing the two parts to be joined together to form a complete cover assembly that encloses the display panel.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The latching portion of the back cover is inserted into and engaged with the hook structure on the front cover, creating a nested assembly relationship. The second side wall of the back cover is bent forward to form the latching portion that fits within the hook structure.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Strength

If multiple fastening components are used to secure the cover, then structural integrity is improved, but ease of manufacture decreases

Engineering Contradiction:

Improvestructural integrityVSAvoidassembly process

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The latching portion is designed to be elastically deformable, allowing it to be inserted into the hook structure and automatically latch into position without requiring additional fastening operations. The elastic deformation enables the latching portion to engage with the hook and maintain a secure connection through its own elastic properties.

Inventive Principle:

Principle #25Self-service

3Reliability

If a latching portion with elastic deformation is used, then secure fastening is achieved, but manufacturing precision requirements increase

Engineering Contradiction:

Improvesecure fasteningVSAvoidlatching geometry

Core Design Contradiction:

ReliabilityVSManufacturing precision

Solution Approach 1:

The latching portion is designed with specific geometric parameters including a bending radius and thickness that enable elastic deformation. The second side wall is bent forward with a controlled radius to form the latching portion, and the thickness is optimized to provide appropriate elastic properties for reliable engagement with the hook structure.

Inventive Principle:

Principle #35Parameter changes
