Solution Overview

Problem

The challenge of preventing window damage during loading on a substrate loading unit and ensuring effective strengthening processes in display device manufacturing is addressed.

Innovation Solution

A substrate loading unit design featuring first and second frames with adjustable support parts that rotate between two states, allowing for increased distance between support parts during loading and reduced risk of collision or shaking during strengthening processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the support parts are positioned close together to ensure stability during strengthening, then the strengthening effectiveness is improved, but the window may be damaged during loading

Engineering Contradiction:
Improvestrengthening effectivenessVSAvoidwindow damage during loading
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The support parts are designed to be rotatable about an axis parallel to the second direction, enabling dynamic reconfiguration between two states: extended in the third direction during loading to prevent damage, and extended in the first direction during strengthening to ensure stability and effectiveness

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The distance between adjacent support parts is variable, changing from a larger distance in the first state (preventing window damage during loading) to a smaller distance in the second state (ensuring stability during strengthening). This parameter change allows the system to adapt to different process requirements

Inventive Principle:
Principle #35Parameter changes

2Object-affected harmful factors

If the support parts are positioned far apart to prevent window damage during loading, then the window safety is improved, but the window may shake or move during strengthening

Engineering Contradiction:
Improvewindow damage preventionVSAvoidwindow stability during strengthening
Core Design Contradiction:
Object-affected harmful factorsVSStability of the object's composition

Solution Approach 1:

The rotatable support parts enable dynamic adjustment of their configuration: in the first state they are spaced far apart to prevent damage during loading, and in the second state they are positioned closer together to ensure stability during strengthening, thus resolving the contradiction through temporal separation of functions

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The support parts are configured in the first state (extended in third direction) before the loading operation to prevent damage, then reconfigured to the second state (extended in first direction) before the strengthening operation to ensure stability, performing the appropriate action in advance for each process

Inventive Principle:
Principle #10Preliminary action

Implementation Method 1

a plurality of support parts disposed on side surfaces of the first support bars, which are defined as surfaces that face each other, and a state, in which the plurality of support parts extend in a third direction crossing a plane defined by the first direction and the second direction, is defined as a first state, and a state, in which the plurality of support parts extend in the first direction, is defined as a second state, and a distance between support parts adjacent to each other in the first direction among the plurality of support parts varies when the plurality of support parts is changed from the first state to the second state

AI summary

A substrate loading unit includes: a first frame; a second frame spaced apart from the first frame in a first direction; and fixed parts disposed between the first frame and the second frame, and spaced apart from each other in a second direction. The fixed parts include: support bars extending in the first direction, and a plurality of support parts disposed on side surfaces of the first support bars, the side surfaces facing each other. A state, in which the support parts extend in a third direction is defined as a first state, and a state, in which the support parts extend in the first direction, is defined as a second state, and a distance between support parts adjacent to each other in the first direction among the plurality of support parts varies when the plurality of support parts is changed from the first state to the second state.
