Solution Overview

Problem

Existing methods for texturing tire surfaces, such as grinding or using complex devices, are inefficient and require material removal, whereas there is a need for a method that can create lacerations without removing material or requiring complex mounting.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual grinding is used to texture tire surfaces, then traction is improved, but the process is slow and time-consuming

Engineering Contradiction:

Improvetexturing speedVSAvoidtime required for manual grinding

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical grinding with a power-driven rotating disc mechanism. The disc rotates at high speed and uses multiple pointed lacerating elements arranged in patterns to automatically score the tire surface, eliminating the need for slow manual grinding while maintaining effective traction texturing.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The cutting action is divided into multiple discrete lacerating elements (teeth, points, or blades) arranged in specific patterns on the disc. Each element creates individual lacerations in the tire rubber, and the combined effect of many elements working simultaneously achieves complete surface texturing much faster than manual grinding.

Inventive Principle:

Principle #1Segmentation

2Manufacturing precision

If complex texturing devices are used, then texturing capability is improved, but device complexity increases and requires tire mounting

Engineering Contradiction:

Improvetexturing pattern precisionVSAvoidcomplexity of texturing device

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The power-driven disc attachment can be universally applied to different tire types and sizes by simply changing the disc itself rather than requiring complex mounting systems. The disc serves multiple functions: it provides the rotating motion, holds the lacerating elements in precise patterns, and can be adapted to various power tools, making the system versatile and simple.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention extracts the essential texturing function from complex mounting systems and concentrates it into a simple rotating disc with lacerating elements. By removing unnecessary complexity and focusing only on the core cutting action, the device achieves precise texturing patterns without requiring elaborate support structures or tire mounting mechanisms.

Inventive Principle:

Principle #2Taking out (Extraction)

3Reliability

If cutting means are used to remove rubber from tire surface, then surface preparation is improved, but material is removed from the tire

Engineering Contradiction:

Improvesurface preparation qualityVSAvoidrubber material removal

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

Instead of removing rubber material through abrasion, the lacerating elements create partial cuts or scores in the tire surface that penetrate only partway through the tread depth. This partial action is sufficient to create the desired surface texture for traction and heat distribution without excessive material removal, preserving tire integrity and longevity.

Inventive Principle:

Principle #16Partial or excessive action
