Solution Overview

Problem

Traditional methods for transmitting liquid crystal display panels during manufacturing, which involve contact with wheels, result in imprinting, reduced passing rates, and risks of scratching, pollution, deformation, and static electricity due to friction.

Innovation Solution

A non-contact air-float guide wheel system with a magnetic wheel driving device and elastic layers to suspend and move the panels without direct contact, using air-flow through gas holes on a platform to maintain panel stability and reduce friction-related issues.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If contact transmission with back wheels is used, then the liquid crystal display panel can be transmitted to different machines, but imprint remains on the surface and the film becomes waved away reducing passing rate

Engineering Contradiction:
Improvepanel transmission capabilityVSAvoidsurface flatness
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent uses pneumatic principles by introducing air through gas holes in the transmission platform to create an air cushion between the panel and the platform surface. This pneumatic cushion enables non-contact transmission, eliminating the imprint and wave deformation caused by direct wheel contact while maintaining effective panel transport.

Inventive Principle:
Principle #29Pneumatics and hydraulics

Solution Approach 2:

The patent replaces the traditional mechanical contact transmission system (back wheels) with a magnetic wheel driving device that operates through magnetic field interaction. The magnetic wheels rotate without physically touching the panel, substituting mechanical contact with magnetic field-based propulsion to avoid surface damage.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If contact transmission with wheels is used, then the panel can be moved, but scratching, polluting or deforming occurs due to friction

Engineering Contradiction:
Improvepanel movementVSAvoidsurface damage
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The air cushion generated by gas holes providing upward air flow creates a protective pneumatic barrier between the transmission surface and the panel. This barrier enables panel movement while preventing direct contact that would cause scratching, polluting, or deforming.

Inventive Principle:
Principle #29Pneumatics and hydraulics

Solution Approach 2:

The patent introduces air as an intermediary substance between the transmission platform and the panel. This air layer acts as a mediator that allows force transmission and panel movement without direct solid-to-solid contact, thereby eliminating friction-related surface damage.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If contact transmission is used, then the panel can be transmitted, but static electricity is produced from friction reducing passing rate

Engineering Contradiction:
Improvepanel transmissionVSAvoidstatic electricity
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

By using pneumatic air cushion transmission through gas holes, the system eliminates the friction between the panel and transmission surface that generates static electricity. The non-contact air-based transmission prevents charge buildup while maintaining effective panel conveyance.

Inventive Principle:
Principle #29Pneumatics and hydraulics

Solution Approach 2:

The patent substitutes the mechanical friction-based transmission system with a magnetic field-based system using magnetic wheels. This replacement eliminates the friction that produces static electricity, preventing the harmful electrostatic effects that reduce passing rate.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
