Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing electrically insulating protective gloves using natural rubber and synthetic polyisoprene involve energy-intensive vulcanization, produce allergenic materials, and result in non-reusable waste, failing to meet modern requirements for arc flash protection and sustainability.
Innovation Solution
A method using a mixture of thermoplastic elastomers, particularly SEBS-based compounds, combined with a pigment, is employed without vulcanization, allowing for the production of gloves that meet electrical, mechanical, and thermal protection standards through a dipping process that reuses materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vulcanization process is used to manufacture protective gloves from natural rubber and synthetic polyisoprene, then the gloves meet electrical insulation and mechanical strength requirements, but the process is energy-intensive and produces allergenic materials
Solution Approach 1:
The patent changes the material parameter from natural rubber/synthetic polyisoprene to thermoplastic elastomers, and changes the processing parameter from vulcanization to dipping process. This parameter change eliminates the need for energy-intensive vulcanization while maintaining the required electrical insulation and mechanical properties through the inherent properties of thermoplastic elastomers.
Solution Approach 2:
The patent uses composite materials by combining thermoplastic elastomers with pigments and other additives to create a material that meets both electrical insulation requirements and arc flash protection requirements, while being processable without vulcanization.
2Strength
If vulcanization process is used to manufacture protective gloves, then the gloves achieve required mechanical properties, but the process generates allergenic components and prevents material recycling
Solution Approach 1:
The patent changes the material composition parameter from natural rubber/synthetic polyisoprene to thermoplastic elastomers, which inherently do not contain allergenic components. The mechanical properties are maintained through the selection of appropriate thermoplastic elastomer formulations and the dipping process parameters.
3Reliability
If conventional materials and processes are used for protective gloves, then electrical insulation standards are met, but arc flash protection and sustainability requirements are not addressed
Solution Approach 1:
The patent develops composite materials based on thermoplastic elastomers that can be formulated to provide both electrical insulation and arc flash protection. The composite nature allows incorporation of pigments and additives that enhance both protective functions and sustainability characteristics.
Solution Approach 2:
The patent changes the material class from traditional rubber compounds to thermoplastic elastomers, enabling the material to be processed without vulcanization. This parameter change allows for sustainable manufacturing and enables the material to meet modern requirements for arc flash protection while maintaining electrical insulation properties.
