Tire Surface Printing Using Base Rubber Color

Solution Overview

Problem

Decorative coating on tire surfaces requires numerous man-hours and high costs due to the use of multiple superposed paints, necessitating a reduction in both man-hours and cost for printing.

Innovation Solution

A tire with a printed region featuring a dark-colored base color and a bright-colored portion surrounding it, where the dark-colored portion is unpainted and the bright-colored portion includes a white-colored layer as the lowermost layer, reducing the need for multiple paints and enhancing visibility and durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If multiple paints are superposed for decorative coating, then the printing quality and visibility are improved, but the man-hours and cost increase

Engineering Contradiction:

Improveprinting qualityVSAvoidman-hours

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The invention extracts and eliminates the unnecessary white-colored undercoat layer from the conventional multi-layer printing process. By using the black base color of the tire rubber itself as the foundation, the patent removes the need for additional white paint application, thereby reducing printing steps and man-hours while maintaining visual contrast and printing quality through the bright-colored portion surrounding the dark-colored portion.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention utilizes the tire's own black base color as the dark-colored portion, making the tire material itself serve the function of providing the dark background. This self-service approach eliminates the need for separate black paint application, as the tire's inherent color is directly used for the decorative pattern's dark areas, reducing both materials and man-hours.

Principle #25Self-service

2Manufacturing precision

If multiple paints are superposed for decorative coating, then the printing quality and visibility are improved, but the cost increases

Engineering Contradiction:

AI summary

Provided is a tire and a tire surface printing method which are capable of reducing man-hours and cost required for application of printing on the tire surface. The tire and the tire surface printing method include, on an outer surface of at least one of side portions (3) thereof, a printed region (5) formed by printing. The printed region (5) includes: a dark-colored portion (7) having a black color, which is a base color of the tire; and a bright-colored portion (9) that has a color different from the black color and that is located to surround the dark-colored portion (7). The dark-colored portion (7) is not applied with any paint, and the bright-colored portion (9) includes a white-colored layer (11) that includes a white color paint and that is located as the lowermost layer being in contact at least with the outer surface (3a) of the side portion (3).
