Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The assembly process of LCD devices is time-consuming and inconvenient due to the need for precise positioning of protrusions and notches in the bezel and back plate, which complicates the engagement of the liquid crystal panel and backlight module.

Innovation Solution

An LCD device with a receiving box that integrates a bezel and back plate as a one-piece body, allowing the back plate to rotate and simplifying the engagement of the backlight module and liquid crystal panel through a design where protrusions easily align with corresponding notches, eliminating the need for precise positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If protrusions and notches are used for engagement between bezel and back plate, then the components can be fastened together, but precise positioning is required which makes the assembly process time-consuming and inconvenient

Engineering Contradiction:

Improveengagement reliabilityVSAvoidassembly convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent integrates the bezel and back plate into a single integrated component structure. The bezel and back plate are combined as one piece with a unified engagement mechanism, eliminating the need for separate positioning operations between two distinct components. This merging reduces assembly complexity and time while maintaining reliable engagement through the integrated structure.

Inventive Principle:

Principle #5Merging (Combining)

2Stability of the object's composition

If multiple engagement points with protrusions and notches are used, then the liquid crystal panel and backlight module can be securely fastened, but the positioning operation becomes more complex and time-consuming

Engineering Contradiction:

Improvecomponent stabilityVSAvoidassembly speed

Core Design Contradiction:

Stability of the object's compositionVSProductivity

Solution Approach 1:

By combining the bezel and back plate into one integrated component, the patent reduces multiple separate positioning operations into a single engagement action. The integrated structure maintains stability through its unified design while significantly improving assembly speed by eliminating sequential positioning steps.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated bezel-back plate structure is pre-configured with engagement features during manufacturing. The protrusions and engagement surfaces are predetermined and fixed in their relative positions, eliminating the need for operators to perform precise positioning during assembly. This preliminary configuration of the engagement geometry enables rapid assembly while maintaining component stability.
