Solution Overview

Problem

In the baking process of color filters, condensate formed from solvent volatilization easily drops onto the substrate when the access door is opened, contaminating the substrate and affecting production quality.

Innovation Solution

A baking device with an access door featuring grooves on its inner side surface to collect condensate, combined with a pipeline for condensate discharge and a stable gas flow field using inlets and outlets to reduce condensate flow resistance and prevent contamination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the access door is opened to remove the substrate, then the substrate can be taken out for next process, but the condensate on the access door inner surface drops onto the substrate causing contamination

Engineering Contradiction:

Improvesubstrate processing efficiencyVSAvoidsubstrate contamination

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The groove structure on the access door inner surface acts as an intermediary element that intercepts and collects condensate before it can reach the substrate. The groove serves as a mediating structure that changes the path of condensate flow, preventing direct contact between condensate and substrate during door opening operations.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The condensate that would normally be harmful (causing contamination) is redirected into the groove structure, where it is collected and contained. The harmful condensate flow is converted into a controlled collection process, transforming the harmful effect into a manageable situation where condensate is trapped in the groove rather than contaminating the substrate.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

2Productivity

If the access door is opened quickly to maintain production rhythm, then efficiency is improved, but condensate has more time to flow and drop onto the substrate

Engineering Contradiction:

Improveproduction rhythmVSAvoidsubstrate cleanliness

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The groove structure is pre-configured on the access door inner surface before the door is opened. This preliminary structural preparation ensures that when the door opens at any speed, the condensate is immediately intercepted by the pre-existing groove structure, preventing contamination regardless of the door opening speed required to maintain production rhythm.
