Ethylene-Based Disposable Gloves with Surface Modification Agents
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional disposable gloves made from low density polyethylene and high density polyethylene may not be comfortable and tend to tear easily, while alternative materials like latex and vinyl have drawbacks such as allergic reactions and environmental impact concerns, and existing ethylene-based gloves lack improved donning and gripping abilities.
Innovation Solution
The development of disposable gloves constructed from multiple ethylene-based polymer layers, including metallocene-linear low density polyethylene, ethylene-vinyl acetate copolymer, and linear low density polyethylene, with surface modification agents incorporated to enhance donning and gripping properties, and optionally colored for size or handedness indication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If disposable gloves are made from low density polyethylene and high density polyethylene, then material cost is reduced and chemical resistance is improved, but comfort deteriorates and tear resistance worsens
Solution Approach 1:
The patent applies composite materials by combining multiple ethylene-based polymers (metallocene-linear low density polyethylene, ethylene-vinyl acetate copolymer, and linear low density polyethylene) in specific layers to create a glove material that achieves both cost-effectiveness and improved comfort characteristics
Solution Approach 2:
The patent implements local quality by creating different layers with specific polymer compositions tailored for different functions: inner layers optimized for comfort and donning, outer layers for durability and chemical resistance, allowing each region of the glove to have optimized properties
2Strength
If disposable gloves are made from metallocene-linear low density polyethylene and ethylene-vinyl acetate copolymer, then comfort and tear resistance are improved, but donning ability and gripping ability deteriorate
Solution Approach 1:
The patent applies local quality by incorporating surface modification agents specifically in the inner layers that contact the hand, while maintaining different polymer compositions in outer layers for tear resistance, allowing localized optimization of donning ability without compromising overall strength
Solution Approach 2:
The patent uses parameter changes by modifying surface properties through surface modification agents and adjusting polymer composition ratios to achieve optimal balance between tear resistance and donning ability
3Ease of manufacture
If conventional polyethylene gloves are manufactured, then material cost is reduced, but environmental impact worsens and barrier capability deteriorates
Solution Approach 1:
The patent applies composite materials using ethylene-based polymers that provide improved barrier properties against contaminants while maintaining cost-effectiveness and reducing environmental impact compared to traditional latex and vinyl materials
