Cut-Resistant Glove Thumb Webbing for Rotisserie Spit Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Liquid proof heat resistant gloves used in deli settings are prone to damage from the sharp rotisserie spit, leading to costly replacements and potential injury from hot grease penetration through tears.
Innovation Solution
A glove with an integrally formed protective member in the thumb webbing region, made from a material that withstands high temperatures and is impermeable, featuring a distinct color to visually indicate damage and prevent further use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If liquid proof heat resistant gloves are used to protect hands from high heat and hot liquids, then hand protection from heat and liquids is improved, but the glove surface is prone to cutting damage from the sharp spit
Solution Approach 1:
The glove is constructed with multiple layers including an inner heat-resistant material layer and an outer cut-resistant material layer. This composite structure combines the thermal protection properties of materials like leather or heat-resistant synthetics with the cut-resistant properties of materials like Kevlar or other high-strength fibers, allowing the glove to simultaneously resist both heat and cutting forces from the spit.
Solution Approach 2:
The glove features enhanced protective properties specifically at the thumb crotch region where the spit makes contact. This area is reinforced with additional cut-resistant material or a different material composition compared to other parts of the glove, providing localized protection where it is most needed during the chicken removal process.
2Object-affected harmful factors
If the glove is made from impermeable heat resistant material, then protection from hot grease penetration is improved, but damage from the sharp spit leads to costly replacements
Solution Approach 1:
The combination of heat-resistant impermeable material with cut-resistant material creates a glove that maintains its protective barrier integrity. The cut-resistant outer layer prevents the spit from cutting through to the inner heat-resistant layer, ensuring the impermeable barrier remains intact and functional, thereby reducing replacement frequency.
Solution Approach 2:
The glove design anticipates the cutting hazard by incorporating a protective outer layer that absorbs and resists the cutting action of the spit before it can compromise the inner heat-resistant barrier. This preemptive protection prevents damage that would otherwise lead to glove failure and replacement.
3Reliability
If a protective device is added to protect the glove from cutting, then cut resistance is improved, but the device must withstand high temperatures without melting
Solution Approach 1:
The outer protective layer is specifically selected from materials that possess both high cut resistance and high heat resistance properties. Materials such as certain high-strength fibers or heat-treated leather are used that maintain their structural integrity and protective capabilities at temperatures exceeding 500 degrees Fahrenheit while simultaneously resisting cutting from the sharp spit.

AI summary
A glove has a protective member in the thumb-crotch region and includes a textured outer surface. The protective member is configured to protected against slicing done by sharp objects. The textured outer surface enables grip ability in greasy environments. The textured outer surface may be formed via a foaming process during manufacture of the glove. There may be a colored layer between an inner liner and the protective member that establishes a color splash effect in the event that a portion of the glove ruptures or fails.
