Solution Overview

Problem

Conventional screw fixation in display devices is time-consuming, inconvenient, and increases material and labor costs, while also reducing production efficiency.

Innovation Solution

A snap-fit connection system between the backplane and the board, utilizing slots on the backplane and hooks on the board, allows for quick assembly and disassembly without the need for screws, reducing material and labor costs and improving production efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If screw fixation is used to fix the board on the backplane, then the connection is stable and reliable, but the assembly time is long and production efficiency is low

Engineering Contradiction:

Improveconnection stabilityVSAvoidproduction efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent replaces the traditional screw fixation mechanical system with a snap-fit connection system. The board includes positioning protrusions that engage with corresponding positioning cavities on the backplane, eliminating the need for screws, studs, and complex assembly tools. This substitution maintains connection reliability while dramatically reducing assembly time and improving production efficiency.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If screw fixation is used to fix the board on the backplane, then the connection is secure, but the material cost and labor cost are increased

Engineering Contradiction:

Improveconnection securityVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent extracts and eliminates the screws and studs from the fixation system, retaining only the essential positioning and securing functions through integrated positioning protrusions and cavities. This reduction in components directly lowers material costs while the simplified structure reduces assembly labor costs.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The positioning protrusions and cavities are integrated directly into the board and backplane structures, merging the fixation function with the structural components themselves. This eliminates the need for separate fastening hardware, reducing both material costs and assembly complexity.

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If screw fixation is used to fix the board on the backplane, then the connection is stable, but the assembly process is complex and time-consuming

Engineering Contradiction:

Improveconnection stabilityVSAvoidassembly time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The positioning protrusions and cavities are pre-formed as integral parts of the board and backplane structures during manufacturing. This preliminary action eliminates the need for separate fastening operations during assembly, allowing for rapid connection by simply engaging the pre-configured positioning features, thereby drastically reducing assembly time while maintaining connection stability.
