Solution Overview

Problem

Existing methods for applying paint to glass plates, particularly for partial enameling, are inefficient due to high paint consumption, manual masking, and lengthy setup times, leading to increased costs and inaccuracies.

Innovation Solution

A device where the glass plate remains stationary, and a movable inking roller with precise electronic control applies paint only to the desired edge or area, reducing paint waste and eliminating the need for manual masking, allowing for precise application and efficient production.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a long paint applicator roller is used to cover the entire glass plate width, then the entire surface can be painted, but paint consumption increases significantly and cleaning time increases

Engineering Contradiction:
Improvepaint application areaVSAvoidpaint consumption
Core Design Contradiction:
Area of stationary objectVSLoss of substance

Solution Approach 1:

The glass plate surface is divided into multiple segments corresponding to different panes or sections. Instead of using one long roller to cover the entire width, multiple shorter rollers are used, each serving a specific segment. This segmentation reduces paint consumption by limiting the painted area to only the required sections while maintaining complete coverage capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The paint applicator system is made dynamic by allowing individual rollers to be independently moved into position or removed from the glass plate width. This dynamic configuration enables the system to adapt to different production requirements, painting only the necessary areas with the minimum number of rollers, thereby reducing paint consumption and cleaning requirements.

Inventive Principle:
Principle #15Dynamics

2Area of stationary object

If a long paint applicator roller is used, then full-surface painting is achieved, but cleaning effort and setup time increase significantly

Engineering Contradiction:
Improvepaint application areaVSAvoidcleaning time
Core Design Contradiction:
Area of stationary objectVSLoss of time

Solution Approach 1:

The paint applicator system is segmented into multiple independent rollers that can be individually positioned or removed. When only partial painting is required, fewer rollers are used, which directly reduces the cleaning effort and time needed. Each roller can be independently cleaned or replaced without affecting the entire system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system allows dynamic adjustment of the number of active rollers based on the painting requirements. Rollers can be quickly moved into or out of position, enabling rapid reconfiguration for different production batches. This dynamic capability significantly reduces setup time and cleaning effort compared to a fixed long-roller system.

Inventive Principle:
Principle #15Dynamics

3Manufacturing precision

If manual masking is used for partial enameling, then precise area control is achieved, but production time and labor intensity increase

Engineering Contradiction:
Improvearea control precisionVSAvoidproduction speed
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

Manual masking operations are replaced by a mechanical paint applicator system with precisely positioned rollers. The rollers can be accurately positioned to apply paint only to the required areas, eliminating the need for manual masking while maintaining high precision. This mechanical substitution significantly increases production speed and reduces labor intensity.

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

Solution Approach 2:

The system changes the parameter of paint application precision from manual control to mechanically controlled roller positioning. By adjusting the position and number of rollers, precise area control is achieved without manual intervention. This parameter change from manual to automated control maintains manufacturing precision while dramatically improving productivity.

Inventive Principle:
Principle #35Parameter changes

4Productivity

If the glass plate is moved through a fixed paint applicator, then continuous production is achieved, but paint application precision decreases

Engineering Contradiction:
Improveproduction continuityVSAvoidpaint application precision
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

Instead of moving the glass plate through a fixed paint applicator, the invention inverts the approach by keeping the glass plate stationary and moving the paint applicator rollers across the glass surface. This inversion allows for precise control of paint application while maintaining production continuity, as multiple rollers can be sequentially positioned and applied to different areas of the same glass plate.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The system employs dynamic positioning of paint applicator rollers that can be precisely moved to any required location on the stationary glass plate. This dynamic capability enables high-precision paint application while maintaining production efficiency, as the rollers can be quickly repositioned between applications without requiring glass plate movement or complex alignment procedures.

Inventive Principle:
Principle #15Dynamics
