Solution Overview

Problem

Conventional fluid-driven illumination devices integrated with fire-fighting nozzles suffer from reduced water pressure and flow due to the turbine generator, limiting their effectiveness in complex and unpredictable fire scenes, and impose additional burden on firefighters due to their weight and requirement for two-handed operation.

Innovation Solution

An adjustable fluid-driven illumination device with a turbine generator that can move between the nozzle and grip, allowing it to generate power only when needed for illumination, thereby maintaining full water pressure and flow during fire suppression by using a revolver, trigger, or button to control the turbine generator's position relative to the fluid flow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the turbine generator is integrated into the fluid passage of the fire-fighting nozzle, then electric power is generated for illumination, but water pressure and flow are reduced

Engineering Contradiction:
Improveelectric power generationVSAvoidwater pressure
Core Design Contradiction:
Use of energy by moving objectVSStress or pressure

Solution Approach 1:

The turbine generator is designed to be movable rather than fixed, allowing it to dynamically enter and exit the fluid passage based on operational needs. The turbine can be positioned within the nozzle to generate power when illumination is required, and removed when full water pressure is needed, making the system adaptive to different fire suppression scenarios

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The illumination system is separated from the main nozzle structure, with the turbine generator mounted on a movable platform or carriage that can independently enter and exit the fluid passage. This segmentation allows the illumination function to be activated only when needed without continuously interfering with water flow

Inventive Principle:
Principle #1Segmentation

2Use of energy by moving object

If the turbine generator is integrated into the fluid passage of the fire-fighting nozzle, then electric power is generated for illumination, but water flow amount is reduced

Engineering Contradiction:
Improveelectric power generationVSAvoidwater flow amount
Core Design Contradiction:
Use of energy by moving objectVSQuantity of substance

Solution Approach 1:

The turbine generator's position is made dynamic, allowing it to be inserted into the fluid passage only when illumination is required. When the turbine is positioned within the nozzle, it generates electric power from the water flow; when removed, full water flow is restored. This dynamic positioning resolves the contradiction between power generation and maintaining water flow quantity

Inventive Principle:
Principle #15Dynamics

3Illumination intensity

If the flashlight is disposed on the helmet, then illumination is provided, but additional burden is imposed on the firefighter

Engineering Contradiction:
ImproveilluminationVSAvoidfirefighter burden
Core Design Contradiction:
Illumination intensityVSWeight of moving object

Solution Approach 1:

The illumination system is designed to be self-powered, with the turbine generator converting kinetic energy from the water flow directly into electrical power to drive the light-emitting elements. This eliminates the need for batteries or external power sources that would add weight to the firefighter's equipment, as the system generates its own power from the existing water supply

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The illumination function is merged with the fire-fighting nozzle system itself, rather than being a separate helmet-mounted device. The turbine generator and light-emitting elements are integrated into the nozzle structure, allowing the firefighter to have both water suppression and illumination functions in a single piece of equipment, reducing overall burden

Inventive Principle:
Principle #5Merging (Combining)

4Stress or pressure

If the fire-fighting nozzle is operated with two hands to securely hold the nozzle, then water pressure is maintained, but the firefighter cannot spare extra strength to hold the flashlight

Engineering Contradiction:
Improvewater pressureVSAvoidillumination operation
Core Design Contradiction:
Stress or pressureVSEase of operation

Solution Approach 1:

The flashlight and nozzle are merged into a single integrated unit, with the light-emitting elements positioned on or near the nozzle. This integration means the firefighter holds both the nozzle and the illumination device simultaneously as one piece of equipment, eliminating the need to separately manage a helmet-mounted flashlight while maintaining secure two-handed grip on the nozzle for water pressure control

Inventive Principle:
Principle #5Merging (Combining)

AI summary

An illumination device includes a nozzle, a grip, at least one light element connected to the nozzle, and a moveable turbine generator electrically connected to the light-emitting element. The turbine generator includes at least one rotatable blade. When the turbine generator is moved into the nozzle, the impact of a fluid flowing through the nozzle causes the rotatable blade to rotate, thereby generating electric power to power the light-emitting element. When the turbine generator is moved into the grip, the rotatable blade is not subjected to the impact of the fluid flowing through the nozzle, stopping the turbine generator from generating the electric power.
