Flexible Fire Detection Cable for Collapsible Spray Booth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile spray booths require disassembly and reassembly of fire safety systems, including nitrogen lines and mechanical detection mechanisms, when moved from one location to another, leading to reduced portability, increased costs, and delays due to inspection and certification requirements.
Innovation Solution
A mobile automotive spray booth with a collapsible enclosure and a fire suppression system that includes a flexible fire detection cable or cable assembly and an electronic actuator system, allowing the enclosure to collapse without disassembling these components, thus enhancing mobility and reducing maintenance complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rigid nitrogen lines and mechanical fire detection mechanisms are used in mobile spray booths, then fire safety is ensured, but the spray booth requires disassembly and reassembly when moved, reducing portability
Solution Approach 1:
The patent replaces rigid nitrogen lines with flexible hoses and rigid mechanical fire detection mechanisms with flexible detection cables. This allows the fire suppression system to remain functional while accommodating the movement and collapse of the spray booth enclosure without requiring disassembly.
Solution Approach 2:
The patent transitions from static, rigid fire safety components to dynamic, flexible components that can adapt to the changing configuration of the mobile spray booth during movement and operation. The flexible hoses and cables maintain fire safety functionality while enabling portability.
2Ease of operation
If fire safety systems are disassembled and reassembled during relocation, then the spray booth can be moved, but inspection and re-certification delays operation resumption
Solution Approach 1:
The flexible detection cables and hoses allow the fire suppression system to remain intact during relocation, eliminating the need for disassembly and subsequent inspection and re-certification processes that would delay operation resumption.
Solution Approach 2:
The patent ensures continuous functionality of the fire suppression system during relocation by using components that remain connected and operational throughout the moving process, eliminating downtime associated with disassembly, inspection, and re-certification.
3Strength
If rigid fire detection cables are used, then structural integrity is maintained, but the enclosure cannot collapse without removing or disassembling the fire detection system
Solution Approach 1:
The patent replaces rigid fire detection cables with flexible detection cables that maintain sufficient structural integrity for fire detection while enabling the enclosure to collapse without removal or disassembly of the fire safety system.
Solution Approach 2:
The patent changes the physical parameter of the fire detection cable from rigid to flexible, allowing the cable to bend and accommodate the collapsing motion of the enclosure while maintaining its fire detection functionality.
Data Source
AI summary
A mobile automotive spray booth having a collapsible enclosure and a fire suppression system. The fire suppression system includes a control unit, a fire detection cable or cable assembly in communication with the control unit, and a fire extinguisher assembly in communication with the control unit. The fire detection cable or cable assembly extends across at least a portion of the collapsible enclosure, and is configured to detect a fire within the collapsible enclosure. The control unit is configured to activate the fire extinguisher assembly to extinguish the fire upon detection of the fire by the fire detection cable or cable assembly. The fire detection cable or cable assembly is configured to bend to allow the collapsible enclosure to collapse from an expanded configuration to a collapsed configuration without removal or disassembly of the fire detection cable or cable assembly.
