Liquid Crystal Module Cover Assembly with Rear Fastening

Solution Overview

Problem

Existing display devices face challenges in easily assembling a cover to a liquid crystal module and integrating a stand, which complicates the assembly process and affects the compactness and visibility of the device.

Innovation Solution

A display device design that includes a liquid crystal module with a cover and a stand, utilizing fastening units such as screw-type or hook-type fasteners to securely couple the cover to the rear surface of the module, and a stand guide unit to facilitate the mounting of the stand, thereby simplifying assembly and reducing bezel size.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a cover is coupled to a liquid crystal module using traditional assembly methods, then the cover can encase the module, but the assembly process becomes complicated and time-consuming

Engineering Contradiction:
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The cover is divided into a first cover and a second cover, with each cover having specific fastening portions that correspond to fastening units on the liquid crystal module. This segmentation allows for simpler, more modular assembly where each cover can be attached independently using straightforward fastening mechanisms rather than complex integrated assembly processes.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fastening units are pre-provided on the rear surface of the liquid crystal module before the cover assembly process begins. This preliminary preparation of fastening structures eliminates the need for complex assembly operations during the covering process, as the fastening portions of the covers can directly engage with the pre-positioned fastening units.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If a stand is integrated into the liquid crystal module assembly, then the display device gains support functionality, but the assembly process becomes more complex

Engineering Contradiction:
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The stand is designed with a stand guide unit that works universally with the cover assembly. The stand guide unit includes a first stand guide portion on the bracket and a second stand guide portion on the cover, creating a standardized interface that simplifies stand integration. This universal guide mechanism allows the stand to be attached to the liquid crystal module through a simple, repeatable process rather than complex custom assembly.

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

3Object-affected harmful factors

If the cover design encases the entire rear surface including central area, then protection is improved, but the bezel size and overall device footprint increases

Engineering Contradiction:
Core Design Contradiction:
Object-affected harmful factorsVSArea of stationary object

Solution Approach 1:

The cover is segmented into a first cover that encases the frame area and a second cover that encases the central area. This segmentation allows the protection function to be distributed across two separate components rather than requiring a single large cover, thereby reducing the overall bezel size and footprint while maintaining comprehensive protection of the liquid crystal module.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The side surface portion of the first cover is designed with different thicknesses at different positions - the front end has a smaller thickness than the rear end. This dimensional variation allows the cover to provide adequate protection at the rear while minimizing the profile and bezel size at the front, effectively reducing the overall device footprint while maintaining protection.

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