Retractable Indoor Fire Hose with Stabilizing Plates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fire extinguishers are inadequate for fighting prolonged fires, especially in residential areas, as they are heavy, bulky, and lack the capacity to effectively combat fires in and around homes.
Innovation Solution
An indoor retractable fire extinguishing apparatus featuring a portable fireproof casing with a rotatable spool and stabilizing plates that allows for easy winding and unwinding of a fire hose, providing a compact and accessible means to fight fires by connecting to an existing water supply, ensuring stability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional fire extinguishers are used, then portability is maintained, but fire-fighting capacity is insufficient for prolonged fires
Solution Approach 1:
The system divides the fire-fighting function into two parts: a lightweight portable control unit (fire hydrant valve assembly) and a separate water supply system (house plumbing). This allows the user to carry only the lightweight valve assembly while the water capacity is provided by the home's existing plumbing system, resolving the contradiction between portability and water capacity.
Solution Approach 2:
The patent uses the home's existing plumbing system as an intermediary to provide large water capacity without requiring the user to carry heavy water tanks. The fire hydrant valve assembly acts as a mediator that connects the user to the abundant water supply already present in the building's infrastructure.
2Quantity of substance
If heavy duty fire hoses are used, then fire-fighting capacity is improved, but ease of operation deteriorates due to weight and bulk
Solution Approach 1:
The patent extracts the heavy-duty hose requirement from the portable equipment and relocates it to the fixed building infrastructure. The fire hydrant valve assembly connects to the building's existing heavy-duty plumbing, allowing high water flow capacity without requiring the user to handle heavy hoses. Only lightweight components need to be portable.
Solution Approach 2:
The solution moves the heavy water supply infrastructure from the mobile dimension to the fixed building dimension. By utilizing the building's permanent plumbing system, the patent achieves high water flow capacity without compromising portability, as the heavy infrastructure remains stationary while only lightweight control elements need to be moved.
3Volume of moving object
If a compact fire hose storage system is used, then space efficiency is improved, but accessibility during emergency deteriorates
Solution Approach 1:
The fire hose is pre-positioned and pre-connected within the building's plumbing system during construction. The fire hydrant valve assembly is pre-installed and ready for immediate use. When emergency occurs, users only need to activate the pre-positioned system rather than deploying equipment from compact storage, thus achieving both space efficiency and rapid accessibility.

AI summary
An indoor retractable fire extinguishing apparatus may include a portable fireproof casing adapted to be positioned inside the building structure. A spool may be rotatably situated inside the fireproof casing. A fire hose may be rolled up about the spool. A plurality of stabilizing plates may be statically mounted to the fireproof casing. A handle may be attached to the spool in such a manner that the handle and the spool may rotate in sync and thereby cause the fire hose to wind and unwind from the spool respectively while the stabilizing plates remain stationary exterior of the fireproof casing. The stabilizing plates may further be directly attached to an outer surface of the fireproof casing such that operating forces acting on the handle and the spool are absorbed and distributed along the stabilizing plates thereby maintaining the fireproof casing at a substantially stable position during winding and unwinding operations.
