Vented Coveralls Aperture Patterns Heat Stress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flame-resistant coveralls are stifling and contribute to heat stress due to their non-breathable materials, lacking adequate ventilation, which is a concern for workers in high-risk industries where fire protection is required.
Innovation Solution
Design of vented coveralls with strategically placed vents, including side and back vents, allowing airflow through apertures and utilizing flame-resistant materials to maintain protection while enhancing air circulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flame-resistant materials are used to provide fire protection, then safety and reliability are improved, but breathability and comfort deteriorate due to heavy non-breathable fabrics
Solution Approach 1:
The patent applies porous materials by incorporating vent panels with aperture patterns that allow air permeation while maintaining flame resistance. The vent panels are constructed with a porous structure that enables breathability and heat dissipation, directly resolving the contradiction between fire protection and comfort by allowing thermal regulation through controlled porosity.
Solution Approach 2:
The patent uses composite materials by combining flame-resistant fabric with vent panels featuring aperture patterns. This composite construction integrates the protective properties of FR materials with the breathable characteristics of patterned vent sections, achieving both fire safety and thermal comfort simultaneously.
2Reliability
If heavy non-breathable fabrics are used for flame resistance, then fire protection is improved, but air circulation and ventilation deteriorate
Solution Approach 1:
The patent applies segmentation by dividing the coverall into distinct functional zones: flame-resistant body panels and vent panels with aperture patterns. This segmentation allows different regions to serve different purposes - the FR panels provide fire protection while the vent panels with aperture patterns provide air circulation, resolving the contradiction between fire protection and ventilation.
Solution Approach 2:
The vent panels utilize porous materials with aperture patterns that enable air permeation. This porous structure directly addresses the air circulation issue by allowing breathability in specific zones while maintaining overall flame resistance through the FR material construction of the coverall.
3Reliability
If long sleeves and long pants are required for fire protection, then safety is improved, but heat stress and discomfort worsen
Solution Approach 1:
The patent applies local quality by providing different material properties in different regions of the coverall. The vent panels with aperture patterns are strategically positioned in high-heat exposure zones (back, underarms, legs) to provide localized breathability and heat dissipation, while maintaining flame resistance in all areas. This resolves the contradiction by addressing heat stress locally where it occurs most.
Solution Approach 2:
The porous vent panels with aperture patterns are placed in strategic locations to provide localized cooling in areas prone to heat buildup. This allows the wearer to maintain full coverage for fire protection while experiencing reduced heat stress through enhanced breathability in critical zones.
