Solution Overview

Problem

Existing breathing apparatus filling stations operate as stand-alone units, leading to depletion of air supplies in primary escape routes while secondary routes remain unused, resulting in inadequate air refilling capacity during emergency situations.

Innovation Solution

Interconnecting breathing apparatus filling stations with air supply lines and remote activation systems to create a redundant air supply network, allowing air to be shared between stations, thereby ensuring a backup air source and increasing the overall filling capacity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If filling stations operate as stand-alone units, then each station can independently refill breathing apparatus, but the air supply capacity is limited to what each individual station can provide

Engineering Contradiction:
Improveair supply availabilityVSAvoidtotal air supply capacity
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

Multiple filling stations are interconnected through air supply lines to form a unified system where air banks from different stations can be combined. When one station depletes its air supply, the system automatically or manually activates air supply from another interconnected station, effectively merging the total air capacity of all stations into a shared resource pool.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

Each filling station is designed to serve multiple functions: it can independently refill breathing apparatus locally, and simultaneously act as a backup air source for other stations through the interconnection system. This multi-functionality ensures that any station can provide air supply support to any other station in the network.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If multiple filling stations are deployed along escape routes, then air refilling capacity increases, but air supplies deplete quickly in used escape routes while remaining unused in other routes

Engineering Contradiction:
Improverefill capacityVSAvoidair supply redundancy
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system incorporates monitoring mechanisms that detect air pressure levels and depletion status at each filling station. When a station's air supply is depleted or low, the system receives feedback and automatically or manually activates air supply from other interconnected stations, ensuring continuous availability without manual intervention or waste of resources in unused routes.

Inventive Principle:
Principle #23Feedback

3Reliability

If filling stations are interconnected with remote activation capability, then air supply redundancy is improved, but system complexity increases

Engineering Contradiction:
Improvebackup air supplyVSAvoidsystem configuration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

A centralized control system or automated control mechanism acts as an intermediary between multiple filling stations, managing the complex interconnections and remote activation functions. This intermediary coordinates air supply distribution, monitors station status, and activates backup stations as needed, simplifying the overall system management while maintaining high reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A Compressed Air Breathing Apparatus (CABA) or Self-Contained Breathing Apparatus (SCBA) is routinely used in environments when there is no breathable air and in emergency situations. However, CABA/SCBA tanks have limited capacity to hold compressed air, and BA filling stations are required in environments in which it may be necessary to refill the CABA/SCBA tanks during an emergency situation. Disclosed is a BA filling station system with a back-up air supply and remote activation. Two or more filling stations are interconnected by one or more air supply lines to provide a flow of compressed air between the filling stations, and one or more remote activation lines to control the flow. Advantageously, the system provides redundancy between the remotely located BA filling stations and substantially improves safety by making available a back-up source of an air supply from another interconnected filling station.
