Solution Overview

Problem

Existing fire extinguishing systems, such as sprinkler systems, are ineffective in targeting the actual fire source and require complex installations, making them costly and impractical for private households, where they may not be able to operate autonomously without electrical or hydraulic connections.

Innovation Solution

A self-contained fire extinguishing device with a housing that includes a fastening mechanism, an extinguishing agent container, sensors for fire detection, and a control device to automatically discharge the extinguishing agent in the direction of the fire, allowing for flexible and autonomous operation without the need for complex installations or connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If sprinkler systems are used for automated fire fighting, then fires can be fought automatically, but the systems cannot target the actual fire source and require complex pipe systems and high-performance pumps

Engineering Contradiction:
Improveautomated fire fightingVSAvoidcomplex pipe system with pumps
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The fire extinguishing system is divided into multiple independently operable extinguishing devices, each equipped with its own sensor and control unit. Each device can autonomously detect and respond to fires in its vicinity without requiring a centralized pipe system or pump infrastructure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The extinguishing agent storage is extracted from a centralized system and integrated directly into individual extinguishing devices. Each device contains its own extinguishing agent container, eliminating the need for building-wide hydraulic infrastructure while maintaining automated fire suppression capability.

Inventive Principle:
Principle #2Taking out (Extraction)

2Extent of automation

If sprinkler systems are used, then automated extinguishing is achieved, but the extinguishing agent damages objects in the room rather than targeting the fire source

Engineering Contradiction:
Improveautomated extinguishing processVSAvoiddamage to objects by extinguishing agent
Core Design Contradiction:
Extent of automationVSObject-affected harmful factors

Solution Approach 1:

Each extinguishing device is equipped with sensors and control mechanisms that enable localized detection and targeted response. The system directs extinguishing agent precisely at the detected fire source rather than dispersing it throughout the entire room, minimizing collateral damage to surrounding objects.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The sensor detects fire characteristics and provides feedback to the control unit, which then adjusts the discharge direction and timing of the extinguishing agent. This closed-loop control ensures the agent is directed accurately at the fire source based on real-time detection data.

Inventive Principle:
Principle #23Feedback

3Ease of manufacture

If local fire extinguishers are used in private households, then installation costs are reduced, but the extinguishers are only effective when manually operated by a user

Engineering Contradiction:
Improvelow installation cost and simplicityVSAvoidmanual operation requirement
Core Design Contradiction:
Ease of manufactureVSExtent of automation

Solution Approach 1:

The extinguishing device incorporates sensors and control mechanisms that enable it to autonomously detect fires and discharge extinguishing agent without human intervention. The device serves itself by automatically responding to fire conditions, eliminating the need for manual operation while maintaining affordability for private households.

Inventive Principle:
Principle #25Self-service
