Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rubber-made golf club grips face challenges in achieving optimal tensile strength and abrasion resistance while maintaining grip performance in wet conditions, particularly in cold weather.
Innovation Solution
The use of a rubber composition comprising hydrogenated acrylonitrile-butadiene rubber or carboxyl-modified acrylonitrile-butadiene rubber as the base rubber, combined with a crosslinking agent, enhances tensile strength and abrasion resistance without compromising grip performance in wet conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional acrylonitrile-butadiene rubber is used as base rubber, then grip performance in wet condition is maintained, but tensile strength is insufficient
Solution Approach 1:
The patent applies parameter changes by hydrogenating the acrylonitrile-butadiene rubber to create hydrogenated acrylonitrile-butadiene rubber with 5-60% hydrogenation. This chemical modification changes the material parameters while maintaining the grip performance characteristics, achieving both improved tensile strength and maintained wet grip performance
Solution Approach 2:
The patent creates a composite rubber composition by combining hydrogenated acrylonitrile-butadiene rubber with specific amounts of acrylonitrile-butadiene rubber (5-50 parts by mass per 100 parts of hydrogenated rubber). This composite approach synergistically combines the high tensile strength of hydrogenated rubber with the wet grip performance of conventional NBR
2Strength
If conventional acrylonitrile-butadiene rubber is used as base rubber, then grip performance in wet condition is maintained, but abrasion resistance is insufficient
Solution Approach 1:
The patent applies parameter changes by introducing carboxyl groups into the acrylonitrile-butadiene rubber through modification with carboxylic acid or its anhydride. This creates carboxyl-modified acrylonitrile-butadiene rubber with enhanced abrasion resistance while preserving the wet grip performance characteristics
Solution Approach 2:
The patent creates a composite rubber composition by combining carboxyl-modified acrylonitrile-butadiene rubber with specific amounts of conventional acrylonitrile-butadiene rubber (5-50 parts by mass per 100 parts of modified rubber). This composite approach synergistically combines the improved abrasion resistance with maintained wet grip performance
