Solution Overview

Problem

Existing panel reversing apparatuses for manufacturing optical display elements cause damage to optical films due to surface contact and pressure, leading to defects like scratches and bubbles when reversing panels with laminated films.

Innovation Solution

A panel reversing apparatus with a single surface contact unit that uses a vacuum adsorbing force to support the panel, maintaining contact with only one surface before and after film lamination, and a rotating unit that reverses the panel's orientation without contacting the laminated surface, thereby preventing damage to the optical films.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If both surfaces of the panel are contacted by surface contact means for supporting the panel during reversal, then the panel can be stably supported, but the optical film is transformed or damaged by contact force or pressing force

Engineering Contradiction:

Improvepanel support stabilityVSAvoidoptical film damage

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The support system is segmented into a single surface contact unit that contacts only one surface of the panel at a time. This segmentation allows the panel to be supported stably while minimizing the contact area and force on any single point, preventing optical film damage during reversal operations

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention inverts the conventional approach of contacting both surfaces simultaneously by contacting only one surface at a time. The single surface contact unit alternates contact between the first and second surfaces during the reversal process, eliminating continuous pressing force on the optical film while maintaining panel stability

Inventive Principle:

Principle #13The other way round (Inversion)

2Productivity

If the panel is reversed with the optical film facing the lower direction, then the manufacturing process can be completed in a predetermined direction, but the contact force or pressing force on the optical film is further increased by the weight of the panel

Engineering Contradiction:

Improvemanufacturing efficiencyVSAvoidoptical film damage

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The support system dynamically adjusts during the reversal process by maintaining vacuum adsorption contact with only one surface at a time. This dynamic approach allows the panel to be reversed efficiently while the vacuum force counteracts the panel weight, preventing additional pressing force on the optical film during the reversal operation

Inventive Principle:

Principle #15Dynamics

3Object-affected harmful factors

If a single surface contact unit is used with vacuum adsorbing force, then the optical film is protected from contact damage, but the device complexity increases

Engineering Contradiction:

Improveoptical film damageVSAvoidapparatus structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The invention replaces traditional mechanical contact-based support systems with a vacuum adsorption system. The single surface contact unit uses vacuum force to hold the panel surface without physical pressing, eliminating mechanical contact damage to the optical film while the overall device structure remains relatively simple

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
