Breathable Polyethylene Gloves for Low-Particle Silicon Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gloves for handling high-purity silicon fail to balance breathability with minimal particle release, leading to contamination risks and discomfort, and require multiple layers for cut resistance, which is cumbersome and costly.
Innovation Solution
A combination of an overglove with a palm made of LDPE film and a back made of Tyvek, welded together, paired with a Dyneema underglove coated with polyurethane, providing breathability and cut resistance while minimizing particle release and lint shedding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If gloves made of ultra-pure polyethylene (PE) are used, then particle release per area is minimized, but breathability is poor causing excessive sweating
Solution Approach 1:
The glove is divided into two functional parts: an inner layer made of ultra-pure PE material that contacts the silicon to minimize particle release, and an outer layer made of breathable textile material that provides ventilation. This segmentation allows each layer to optimize its specific function without compromising the other.
Solution Approach 2:
The glove combines two different materials with complementary properties: ultra-pure polyethylene for low particle release and breathable textile fabric for ventilation. This composite structure resolves the contradiction by integrating the advantages of both materials into a single functional garment.
2Reliability
If multiple layers of gloves are worn for cut resistance, then protection is improved, but device complexity and cost increase
Solution Approach 1:
The patent merges the cut-resistant underglove and the low particle-release overglove into a single integrated glove structure. The cut-resistant fibers are incorporated into the glove body while the ultra-pure PE material forms the palm and finger surfaces, combining both protective functions in one garment rather than requiring separate layers.
Solution Approach 2:
The glove uses composite construction with cut-resistant fibers (such as Dyneema or Kevlar) integrated into the glove body structure, combined with ultra-pure PE material for the contact surfaces. This composite approach provides both cut resistance and low particle release in a single glove layer.
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
This configuration reduces glove consumption by 80%, maintains sterile conditions, and enhances productivity and cost-effectiveness by allowing single-layer underglove use, with lower sodium contamination on silicon fragments.
Implementation Method 1
Due to the vapor diffusion openness and watertightness of the material, gaseous sweat can easily escape through the fiber to the outside.
Implementation Method 2
the textile glove part is additionally reinforced to increase the cut resistance

AI summary
The glove is provided with the palm that is made of polyethylene, where the back of the hand area of the glove is made from a breathable fabric. Both surfaces are connected together permanently. The glove is made of high strength polyethylene fiber with a very high tensile strength, where polyurethane is coated.
