Vented Coveralls Aperture Design for Heat Stress Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flame-resistant coveralls are stifling and contribute to heat stress due to their non-breathable materials, lacking adequate ventilation, which is a concern in high-risk industries where workers are exposed to fire hazards.
Innovation Solution
Design of vented coveralls with strategically placed vents, including side and back vents, allowing airflow through apertures and utilizing fire-resistant materials to maintain protection while enhancing ventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flame-resistant materials are used to protect workers from fire hazards, then safety and fire protection are improved, but breathability and ventilation are worsened causing heat stress
Solution Approach 1:
The patent applies porous materials by incorporating vent panels with aperture patterns that allow air flow through the coverall. These porous structures enable ventilation while maintaining the flame-resistant properties of the base fabric, resolving the contradiction between fire protection and breathability.
Solution Approach 2:
The patent uses composite materials by combining flame-resistant fabric with vent panels featuring aperture patterns. This composite construction allows different regions of the garment to serve different functions: the FR fabric provides fire protection while the aperture-patterned vents provide breathability and heat dissipation.
2Reliability
If heavy non-breathable fabrics are used to meet flame resistance requirements, then fire safety is improved, but comfort and air circulation are worsened
Solution Approach 1:
The patent applies local quality by creating different regions within the coverall with different properties. The main body uses heavy flame-resistant fabric for safety, while specific vent panels with aperture patterns are strategically placed to provide local breathability and comfort in high-heat areas.
3Object-affected harmful factors
If vents are added to FR coveralls to improve ventilation, then heat stress is reduced, but flame resistance may be compromised
Solution Approach 1:
The patent resolves this contradiction by using porous aperture patterns in vent panels that are designed to maintain flame resistance while enabling ventilation. The aperture structure allows air flow for heat stress reduction but the configuration and material selection preserve fire safety properties.
