Solution Overview

Problem

Existing fire suppression systems in commercial cooking establishments and factories often require electricity or external energy sources and may not activate all fire extinguishing units simultaneously, potentially leaving some areas unprotected due to independent operation.

Innovation Solution

A mechanical chain reaction system where valve control units are connected by mechanical linkages, allowing simultaneous activation of multiple fire extinguishing units without the need for electricity, using a mechanical linkage system triggered by fire detectors or manual control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Difficulty of detecting and measuring

If fixed fire suppression systems with electronic sensors are used, then fire detection capability is improved, but device complexity and dependency on external energy sources increase

Engineering Contradiction:

Improvefire detection capabilityVSAvoidsystem complexity

Core Design Contradiction:

Difficulty of detecting and measuringVSDevice complexity

Solution Approach 1:

The patent replaces electronic sensors and electrical control systems with a purely mechanical linkage system. Mechanical detectors respond to fire conditions (heat, smoke) and trigger valve control units through physical linkages, eliminating dependency on external energy sources while maintaining fire detection capability. This mechanical substitution reduces device complexity by removing electronic components, power supplies, and control circuitry.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The mechanical linkage system is self-actuating and does not require external energy sources. The system uses the fire condition itself (heat expansion, mechanical movement of detectors) to trigger the suppression mechanism through the mechanical chain, making the system self-sufficient and independent of external power infrastructure.

Inventive Principle:

Principle #25Self-service

2Device complexity

If independent fire extinguishing units are used, then system simplicity is improved, but fire protection coverage is worsened due to non-simultaneous activation

Engineering Contradiction:

Improvesystem simplicityVSAvoidfire protection coverage

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent merges multiple independent fire extinguishing units into a coordinated system through mechanical linkages. The linkages connect the detectors and valve control units of multiple extinguishers, ensuring they activate simultaneously in response to a fire condition. This merging maintains the simplicity of individual units while achieving reliable comprehensive coverage through synchronized operation.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The mechanical linkages are pre-configured during system installation to connect all valve control units. When a fire condition occurs, the preliminary mechanical connections ensure immediate simultaneous activation of all extinguishing units without requiring electronic signaling or sequential activation, achieving both simplicity and reliability.

Inventive Principle:

Principle #10Preliminary action

3Speed

If electrical control systems are used for fire extinguishing units, then activation speed is improved, but dependency on external energy sources increases

Engineering Contradiction:

Improveactivation speedVSAvoidenergy dependency

Core Design Contradiction:

SpeedVSUse of energy by moving object

Solution Approach 1:

The patent substitutes electrical control systems with mechanical linkages that directly transmit activation force from detectors to valve control units. This mechanical transmission maintains rapid activation speed by eliminating electronic signal delays, while completely eliminating dependency on external energy sources as the mechanical system uses direct physical connection for actuation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
