Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Drive belts with textile overlays face challenges in maintaining optimal friction conditions and noise characteristics both wet and dry, while also ensuring sufficient wear resistance, as existing solutions often compromise on either noise or wear performance depending on the yarn type used.

Innovation Solution

A textile overlay composed of at least two types of yarn that alternate in individual courses at regular intervals, providing both yarn types on both sides of the knitted fabric in fixed ratios, allowing for optimized adhesion, noise, and wear resistance across wet and dry conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-generated harmful factors

If a textile overlay made of cotton yarn is used, then favorable noise characteristics when wet are achieved, but wear resistance deteriorates

Engineering Contradiction:
Improvenoise characteristics when wetVSAvoidwear resistance
Core Design Contradiction:
Object-generated harmful factorsVSReliability

Solution Approach 1:

The patent applies composite materials by combining cotton yarn and polyamide yarn in a plated knitted fabric overlay. The cotton yarn (typically 60-80% of the plating thread) provides favorable noise characteristics when wet, while the polyamide yarn (typically 20-40% of the plating thread) contributes good wear resistance and adhesion. This composite structure allows the overlay to simultaneously achieve noise reduction under wet conditions and maintain durability against wear.

Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent applies composite materials by combining cotton yarn and polyamide yarn in a plated knitted fabric overlay. The cotton yarn (typically 60-80% of the plating thread) provides favorable noise characteristics when wet, while the polyamide yarn (typically 20-40% of the plating thread) contributes good wear resistance and adhesion. This composite structure allows the overlay to simultaneously achieve noise reduction under wet conditions and maintain durability against wear.

Inventive Principle:

Solution Approach 2:

The patent applies local quality by creating a plated knitted fabric where different yarn types are distributed in specific patterns. The plating thread containing both cotton and polyamide yarns is arranged to provide localized properties: cotton dominates for noise reduction in wet conditions, while polyamide provides wear resistance and adhesion. This local differentiation within the overlay structure enables optimization of multiple properties simultaneously.

Inventive Principle:
Principle #3Local quality

4Adaptability or versatility

If the textile overlay is optimized for specific application conditions, then optimal friction conditions are achieved, but the complexity of selecting and configuring the overlay increases

Solution Approach 2:

The patent applies universality by designing a plated knitted fabric overlay that performs multiple functions simultaneously: noise reduction under both wet and dry conditions, wear resistance, and adhesion to the elastic main body. The combination of cotton and polyamide yarns in the plating thread creates a universal overlay structure that addresses multiple performance requirements in a single component, reducing the need for multiple specialized overlays.

Inventive Principle:
Principle #6Universality (Multi-functionality)
