Protective Glove with Localized Polymer and Textile Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective gloves either lack breathability, leading to discomfort during prolonged use or heavy physical exertion, or fail to provide adequate protection against highly concentrated toxic substances, particularly in liquid form.
Innovation Solution
A glove with two distinct sections: a polymer-based section for the gripping surface, which is impermeable to chemicals and water, and a textile surface filter section for breathability, ensuring protection and comfort by preventing the passage of toxic substances while allowing gas and water vapor permeability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If non-breathable rubber gloves are used for protection against chemical toxins, then protection reliability is improved, but breathability deteriorates leading to low wearing comfort
Solution Approach 1:
The patent applies different material properties to different regions of the glove. The palm and finger areas use impermeable polymer material for chemical protection, while the back of the hand uses breathable textile material for comfort. This local differentiation resolves the contradiction by providing protection only where chemical contact is most likely while maintaining breathability in less critical areas.
Solution Approach 2:
The patent combines two distinct materials with complementary properties: an impermeable polymer-based material for chemical resistance and a breathable textile material for comfort. This composite construction allows the glove to simultaneously achieve both high protection reliability and good wearing comfort that single-material gloves cannot provide.
2Ease of operation
If breathable protective gloves with activated carbon adsorption layers are used, then wearing comfort is improved, but protection against highly concentrated liquid toxins deteriorates
Solution Approach 1:
The patent places the impermeable polymer material specifically on the palm and finger surfaces where direct contact with liquid toxins is most likely to occur. The breathable material is used on the back of the hand where liquid toxin contact is less probable. This strategic placement ensures adequate protection against liquid toxins while maintaining breathability for comfort.
Solution Approach 2:
The patent changes the material parameter of impermeability specifically in the contact areas (palm and fingers) while maintaining breathability in non-contact areas. This parameter differentiation allows the glove to provide sufficient protection against liquid toxins without sacrificing overall wearing comfort.
3Reliability
If barrier layers are added to breathable protective gloves, then protection against chemical poisons is improved, but breathability deteriorates impairing wearing comfort
Solution Approach 1:
The patent implements a barrier function locally on the palm and finger areas using impermeable polymer material, rather than applying a barrier layer across the entire glove surface. This localized approach provides necessary chemical protection while preserving breathability in the back of the hand area, thus maintaining wearing comfort during physical exertion.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The glove effectively protects against highly concentrated toxic substances, especially in liquid form, while maintaining high breathability and comfort, making it suitable for extended use under physical stress or high temperatures.
Implementation Method 1
a polymer-based material which is at least essentially impermeable to chemical poisons or warfare agents or at least delays their passage and is at least essentially impermeable to gas and water and im generally also impermeable to water vapor
Implementation Method 2
a textile surface filter material which prevents or at least delays the passage of poisonous and/or pollutants and is at least essentially permeable to gas and/or water vapor
Implementation Method 3
an activated carbon-based adsorption layer over the entire surface of the glove for the adsorption of chemical toxins and warfare agents

AI summary
The glove (1) has two glove sections (2, 3) connected with each other, where one of the sections (2) is made of a polymer-based material that is impervious to chemical toxins and warfare agents or retards passage of the toxins or the warfare agents. The polymer-based material is gas-impervious and water-impervious. Another section (3) is made of textile planar filtering material that prevents or retards the passage of the chemical toxins and warfare agents and is gas-pervious and water-vapor-pervious.
