Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firefighter turnout gear is difficult to dry effectively after washing, leading to mildew or mold issues and reduced effectiveness, as existing drying systems are inadequate for the bulk and design of the gear.
Innovation Solution
A drying system comprising a ducting frame assembly, ventilated garment and gear racks, a blower, and a rolling base with valves and vents, designed to efficiently direct air and manage moisture, using durable materials and adjustable configurations to accommodate various gear types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional drying methods are used on firefighter turnout gear, then the gear bulk and design are accommodated, but the drying effectiveness is insufficient leading to mildew and mold
Solution Approach 1:
The drying system segments the gear drying process by using multiple adjustable racks that can be positioned at different heights and angles, allowing air to circulate through different sections of the bulky turnout gear independently, ensuring thorough drying of all surfaces including interior compartments
Solution Approach 2:
The system adds spatial dimensionality to the drying process by incorporating racks that can be tilted and positioned at various angles, creating three-dimensional air circulation patterns that penetrate the bulk of the gear more effectively than traditional flat drying surfaces
2Reliability
If turnout gear is not dried properly, then equipment integrity is maintained, but mildew and mold damage occurs reducing effectiveness
Solution Approach 1:
The drying system enables continuous air circulation through the gear using fans that operate throughout the drying cycle, maintaining constant moisture removal action rather than intermittent drying, which prevents the conditions necessary for mildew and mold development
Solution Approach 2:
The system changes the environmental parameters within the drying chamber by controlling temperature, humidity, and air flow velocity through adjustable fans and racks, creating optimal conditions for rapid moisture evaporation while preventing microbial growth
3Reliability
If firefighter turnout gear takes too long to dry, then equipment integrity is preserved, but productivity is reduced due to delayed availability
Solution Approach 1:
The system prepares the drying environment in advance by pre-heating the chamber and positioning racks before gear is loaded, so that the drying process begins immediately at optimal conditions, significantly reducing total drying time while maintaining equipment integrity
Solution Approach 2:
The drying system accelerates the moisture removal process by using high-velocity air flow and elevated temperatures to rush through the drying stages, reducing the time required to dry bulky turnout gear from days to hours without compromising equipment integrity

AI summary
A system for supporting and drying personal protective equipment includes a ducting frame assembly, ventilated equipment racks connected to the frame assembly, and valves between the equipment racks and the ducting frame assembly. The system is supported by a base assembly, bracing, or a combination of a base and braces. A blower forces air through the frame assembly and may heat the air and add disinfecting or deodorizing substances to the air flow. Valves may be opened to direct the forced air into equipment racks and through ventilation apertures or openings in the racks. Personal protective equipment may be disposed upon the equipment racks, so that air is ventilated out of the racks and onto and around protective equipment on the racks.
