Solution Overview

Problem

In the manufacturing process of LCD and OLED display devices, the separation of packaging protective films often results in adhesive issues with the needle and clamping members, leading to defects due to carbonization and particle generation during the half-cutting process.

Innovation Solution

A film separation apparatus featuring a mechanical arm with a needle and a stopping member, where the needle tip and stopper move relative to each other in the extension direction of the needle to separate the film from the needle tip, preventing adherence and utilizing a clamping member and adsorption device to manage the film and particles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the needle tip is used to separate the film from the substrate, then the film can be separated from the substrate, but the film adheres to the needle tip causing defects

Engineering Contradiction:
Improvefilm separation reliabilityVSAvoidadhesive contamination
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent extracts the harmful adhesive film from the needle tip by introducing a stopping member that stops the needle tip's movement. This allows the film to be separated from the needle tip through relative movement between the stopping member and needle tip, preventing the film from adhering to the needle tip and causing defects.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The stopping member acts as an intermediary element between the needle tip and the film. By introducing this intermediate component, the patent enables controlled relative movement that separates the film from the needle tip without direct contact, thereby preventing adhesive contamination.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If the needle tip moves to separate the film, then the film can be separated, but carbonization and particle generation occur

Engineering Contradiction:
Improvefilm separation efficiencyVSAvoidcarbonization and particles
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent extracts the harmful carbonization and particles by using the stopping member to halt the needle tip's movement at a controlled position. This prevents excessive friction and heat generation that would cause carbonization and particle generation, while still maintaining effective film separation.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The stopping member provides beforehand cushioning by limiting the needle tip's movement range. This pre-established constraint prevents the needle tip from moving too far, thereby avoiding excessive friction, heat, and the generation of carbonization and particles during the film separation process.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Reliability

If the needle tip is inserted deep into the film, then the film can be fully separated from the substrate, but adherence to the needle tip increases

Engineering Contradiction:
Improvefilm separation completenessVSAvoidadhesive accumulation
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The stopping member serves as an intermediary that mediates between the needle tip and the film. By introducing this intermediate component, the patent enables the needle tip to reach the necessary depth for complete film separation while the stopping member prevents further movement that would cause excessive adhesive accumulation and adherence.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent applies dynamics by creating a controlled relative movement system between the stopping member and needle tip. The stopping member is fixed while the needle tip can move within a limited range, creating a dynamic system that allows complete film separation while preventing excessive adhesive accumulation through controlled movement termination.

Inventive Principle:
Principle #15Dynamics
