Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The durability of connections between transmitting and/or receiving devices and technical rubber articles, such as vehicle tires, is compromised due to permanent stress or material aging, leading to detachment and imperfections in the connection area.
Innovation Solution
An adhesive composition comprising 10 to 80% rubber, 11 to 80% polyolefin, and 2 to 20% hydrocarbon resin is used to attach transmitting and/or receiving devices to technical rubber items, ensuring long-term adhesion by optimizing viscosity and stickiness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transmitting and/or receiving devices are attached to technical rubber articles, then functionality is improved, but connection durability deteriorates due to permanent stress and material aging
Solution Approach 1:
The adhesive is formulated as a composite material containing rubber (10-80 wt%), polyolefin (11-80 wt%), and hydrocarbon resin (2-20 wt%). This multi-component composition combines the elasticity and adhesion of rubber with the strength and stability of polyolefin and the bonding enhancement of hydrocarbon resin, creating an adhesive that can withstand permanent stress and material aging throughout the service life of the technical rubber article.
Solution Approach 2:
The adhesive composition parameters are specifically optimized with defined weight ratios of rubber (10-80%), polyolefin (11-80%), and hydrocarbon resin (2-20%). These parameter ranges are carefully selected to achieve the optimal balance between adhesion, cohesion, and durability, ensuring the adhesive maintains its bonding strength under permanent stress and aging conditions throughout the service life.
2Strength
If conventional adhesives are used for attachment, then initial bonding is achieved, but adhesion fails over time due to stress and aging
Solution Approach 1:
The adhesive combines three distinct material types - rubber for initial adhesion and elasticity, polyolefin for structural strength, and hydrocarbon resin for enhanced bonding. This composite approach ensures both strong initial bonding and sustained long-term adhesion resistance against stress and aging.
Solution Approach 2:
Different components of the adhesive perform specialized functions: rubber provides local elasticity and initial tack, polyolefin provides local structural integrity, and hydrocarbon resin provides local bonding enhancement. This localized functional distribution ensures comprehensive performance throughout the adhesive's service life.
