Protective device for use with a glove
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Liquid proof heat resistant gloves used by deli workers to handle rotisserie chickens are prone to damage from the sharp spit, leading to costly replacements and potential injuries from hot grease penetration through tears.
Innovation Solution
A protective device is integrated into the thumb webbing region of the glove, featuring a trapezoidal-shaped protective member with slits that bends around the thumb and index finger, made from materials resistant to high temperatures and cuts, and a colored layer beneath the outer skin to visually indicate damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If liquid proof heat resistant gloves are used to handle rotisserie chickens, then worker protection from hot grease and high temperature is improved, but the glove surface is prone to cutting damage from the sharp spit
Solution Approach 1:
The patent combines liquid proof heat resistant material with a separate protective coating or layer that provides cut resistance. This composite structure allows the glove to simultaneously resist hot grease penetration and protect against cutting damage from the sharp spit during chicken removal operations.
Solution Approach 2:
The patent applies protective enhancement specifically to the thumb crotch region where the glove is most vulnerable to cutting from the spit. This localized reinforcement targeted at the high-risk area provides cut resistance without compromising the overall heat resistance and liquid proof properties of the glove material.
2Reliability
If the glove is replaced every three days to prevent damage, then worker safety is maintained, but operational costs increase due to frequent replacement
Solution Approach 1:
The patent incorporates a protective coating or reinforcement layer in advance during glove manufacturing, creating a buffer against cutting damage before the glove is put into service. This pre-applied protection extends the service life of the glove beyond the traditional three-day replacement cycle, reducing operational costs while maintaining safety.
Solution Approach 2:
The patent modifies the physical or chemical parameters of the glove material or coating to enhance durability and cut resistance. By changing material properties such as tensile strength, tear resistance, or surface hardness, the glove can withstand repeated use and cleaning cycles without degradation, allowing for less frequent replacement.
3Strength
If a protective device is added to the thumb webbing region, then cut resistance is improved, but device complexity increases
Solution Approach 1:
The patent integrates the protective function directly into the glove construction by combining the liquid proof heat resistant material with an embedded protective coating or reinforcement layer in the thumb crotch region. This merged structure provides cut resistance without adding separate movable parts or complex mechanisms, maintaining glove simplicity while enhancing protection.

AI summary
A color splash effect is established by a darker backdrop color of an outer surface of a liquid proof and heat resistant glove in the event that a portion of the glove ruptures or fails. The color splash effect is accomplished by a lighter and brighter color being visible through the rupture in the glove. The lighter and brighter color may be formed on or as part of a protective member positioned beneath the outer layer. The protective member also protects the wearer against sharp objects contacting the outer layer of the glove and moving over the protective member. Some embodiments provide that the protective member is in a thumb crotch region of the glove.
