Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drill fire extinguishing devices are cumbersome, difficult to transport, and inefficient in penetrating thick obstacles and providing effective fire suppression, often causing water damage and risking firefighter safety due to mechanical and thermal stress on rotating parts, limited applicability to thin-walled structures, and inadequate access to complex building structures.
Innovation Solution
A drill fire extinguishing device with a turbine-driven tool holder that discharges fire extinguishing fluid through stationary discharge openings for cooling and penetration, combined with a nozzle assembly for fine mist distribution, allowing simultaneous drilling and fire suppression without reliance on rotating seals, and adaptable to various building materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fire extinguishing equipment is used, then fire suppression is attempted, but the medium does not reach the source of the fire and only water damage occurs
Solution Approach 1:
The device segments the fire suppression medium into multiple streams through multiple discharge openings distributed around the tool holder, enabling the medium to reach the fire source from multiple angles and paths, thereby improving effectiveness while reducing unnecessary water application to undamaged areas
Solution Approach 2:
The drill bit serves as an intermediary element that creates a passage through obstacles to deliver the fire suppression medium directly to the fire source, acting as a mediator between the water supply system and the hidden fire, ensuring precise delivery without excessive water damage
2Ease of operation
If a turbine with rotating parts is used to drive drilling, then drilling function is achieved, but mechanical and thermal stress on seals reduces reliability
Solution Approach 1:
The patent extracts the sealing requirement from the rotating drill drive system by using a turbine that drives the drill bit through a transmission mechanism with minimal sealing needs, eliminating the complex rotating seals that would otherwise be required in the drill shaft
Solution Approach 2:
The patent replaces the direct rotating drive mechanism with a turbine-based system that uses fluid dynamics to drive the drilling operation, substituting a mechanical rotating seal system with a fluid-coupled transmission system that reduces sealing requirements
3Ease of operation
If existing drill fire extinguishing devices are used, then drilling through obstacles is possible, but the devices are cumbersome and difficult to transport
Solution Approach 1:
The patent merges the drilling function and fire suppression function into a single integrated tool holder assembly, combining what were previously separate heavy devices into one unified lightweight system, thereby improving portability while maintaining both drilling and fire suppression capabilities
4Reliability
If fire extinguishing medium is supplied through rotating parts, then fire suppression is achieved, but high mechanical and thermal stress reduces reliability
Solution Approach 1:
Instead of supplying fire suppression medium through rotating parts as in conventional devices, the patent inverts the approach by using stationary discharge openings that receive medium from stationary passages, eliminating the rotating seal interface and its associated mechanical and thermal stress problems
5Reliability
If conventional fire suppression methods are used in suspended ceiling fires, then access is attempted, but the medium does not reach the fire source and major conflagrations occur
Solution Approach 1:
The device segments the discharge openings to provide multiple discharge paths for the fire suppression medium, allowing the medium to reach fires in complex structures like suspended ceilings from various angles and directions, improving effectiveness without requiring complex access procedures
Solution Approach 2:
The drill bit automatically creates the access path through obstacles while the turbine simultaneously delivers the fire suppression medium through integrated stationary passages, enabling the device to serve itself by combining drilling and suppression functions in a single automated operation without requiring separate access procedures

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables effective fire suppression and drilling through thick obstacles with minimal water damage and reduced risk to firefighters by using a turbine-driven system that distributes fire extinguishing fluid efficiently, ensuring both drilling and fire extinguishing functions without clogging or mechanical stress, suitable for various building materials.
Implementation Method 1
a turbine with an impeller that has at least one stage with a plurality of runner blades and is or can be connected to the tool holder in order, in a drive mode, to drive it in a rotary and/or percussive fashion through the use of the fluid supplied as a drive fluid via the fluid connection
Implementation Method 2
at least one discharge opening, which is provided in a stationary wall of the drill fire extinguishing device and communicates with a fluid chamber provided downstream of the runner blades of the turbine and which constitutes a first flow path that is dimensioned to dispense the fluid—which is used as a drive fluid for operating the turbine in the drive mode—to the area surrounding the drill fire extinguishing device
Implementation Method 3
a nozzle assembly that is embodied in a stationary wall of the drill fire extinguishing device for dispensing the fluid and that communicates/communicate with a fluid chamber provided downstream of the runner blades of the turbine in order, in a fire extinguishing mode, to form a second flow path so that after the fluid has passed through the turbine, it is discharged as fire extinguishing fluid into a space surrounding the drill fire extinguishing device
