Adjustable Fire-Fighting Cannon for Shadow-Free Waste Facility Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire-fighting systems in waste disposal centers suffer from shadow cones, require numerous installations, and are slow and inefficient in extinguishing fires due to their fixed positioning, leading to increased costs and environmental pollution.
Innovation Solution
A fire-fighting cannon with a tubular body that can be mounted on a ceiling or wall, featuring movement means to orient the emission direction in various positions, including inversion, allowing it to cover the entire room surface without shadow cones and intervene promptly and accurately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fire-fighting cannons are arranged on the ground or on support shelves around the perimeter of the industrial shed, then each cannon can intervene in a specific zone to control and extinguish fires, but shadow cones are formed below the cannons where fire intervention is not possible
Solution Approach 1:
The patent applies the dynamics principle by making the cannon's emission direction adjustable through movement means. The cannon can change its orientation from fixed to variable positions, allowing it to adapt to different fire locations and eliminate shadow cones by dynamically directing the fire-fighting fluid flow where needed.
Solution Approach 2:
The patent applies the dimensionality change principle by transitioning from ground-level or shelf-mounted cannons to ceiling mounting. This vertical dimension change allows the cannon to cover the entire room surface including areas that would otherwise be in shadow cones, as the emission direction can be adjusted in three-dimensional space.
2Area of stationary object
If numerous fire-fighting cannons are installed to obtain good surface coverage, then complete coverage is achieved, but the cost for purchase, installation and maintenance increases significantly
Solution Approach 1:
The patent applies the universality principle by designing a single cannon that can perform multiple functions through its adjustable emission direction. One cannon can cover the entire room surface by changing its orientation, replacing the need for multiple fixed cannons, thus reducing the total number of devices required while maintaining complete coverage.
Solution Approach 2:
The patent applies the merging principle by combining the functions of multiple fixed cannons into a single movable cannon. The movement means allow one cannon to assume the positions and orientations that would otherwise require multiple separate cannons, consolidating the system and reducing overall complexity and cost.
3Area of stationary object
If fire-fighting cannons follow a pre-set zig-zag path to cover the entire surface, then complete coverage is achieved, but the process is slow and requires a large quantity of water or other fire-fighting substances
Solution Approach 1:
The patent applies the dynamics principle by replacing the slow pre-set zig-zag path with a dynamically adjustable emission direction. The cannon can rapidly change its orientation to directly target the fire location, eliminating the time-consuming sequential coverage process and significantly improving fire extinguishing speed while reducing the quantity of fire-fighting substances needed.
Solution Approach 2:
The patent applies the preliminary action principle by enabling the cannon to directly target and intervene in the fire location immediately, rather than following a predetermined path. This allows the system to prepare and deliver fire-fighting fluid precisely where needed before the fire spreads, improving response time and reducing resource consumption.

AI summary
A fire-fighting cannon (1) for the management of fires, in particular in a waste disposal centre, comprises a fixed base (2) constrainable to a ceiling or to a vertical wall of a room defining a corresponding lying plane (G), a tubular body (3) extending along an emission direction (F) of at least one jet of fire-fighting fluid. In particular, the tubular body (3) is arranged below or alongside the fixed base (2) with respect to a normal direction (N) to the lying plane (G). The fire-fighting cannon (1) further comprises movement means configured to orient the tubular body (3) between a plurality of operating positions, including an initial position in which the emission direction (F) has a predefined angle of inclination with respect to the normal direction (N). The movement means is configured to orient the tubular body (3) also in a position of inversion in which the emission direction (F) is parallel to the normal direction (N), so as to emit the jet of fire-fighting fluid in a zone of the ground arranged underneath the fire-fighting cannon (1) if the fixed base (2) is constrained to the ceiling, or in a zone with horizontal output if the fixed base (2) is constrained to the wall.
