Solution Overview

Problem

Current gas leakage detection methods in home safety are prone to false and omitted judgments due to reliance on combustible gas alarms, leading to poor accuracy and potential safety hazards.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a combustible gas alarm is used to detect gas leakage, then the detection coverage is expanded, but the measurement precision deteriorates due to false judgments and omitted judgments

Engineering Contradiction:
Improvedetection coverageVSAvoidleakage detection accuracy
Core Design Contradiction:
Area of stationary objectVSMeasurement precision

Solution Approach 1:

The patent segments the detection system into multiple independent alarm devices distributed at different locations along the gas pipeline. Each alarm device independently monitors its local area, and the central control system aggregates data from all segments to achieve comprehensive coverage while maintaining precise localization of leakage points through multi-point comparison.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a central control system as an intermediary that receives data from multiple alarm devices, processes the information through analysis algorithms, and makes centralized judgment decisions. This intermediary layer filters out false alarms by cross-validating data from multiple sources and provides accurate leakage location identification that individual alarms cannot achieve alone.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Area of stationary object

If alarms are installed far from gas leakage positions to cover larger areas, then the detection coverage is improved, but the measurement precision deteriorates due to distance-related detection errors

Engineering Contradiction:
Improvedetection coverageVSAvoidleakage detection accuracy
Core Design Contradiction:
Area of stationary objectVSMeasurement precision

Solution Approach 1:

Instead of installing a single alarm far from the leakage point, the system segments the monitoring into multiple closer alarm devices positioned at intervals along the pipeline. This segmentation allows each device to maintain high detection precision in its local zone while collectively providing wide-area coverage through the network of distributed sensors.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from a single-point detection approach to a distributed spatial network of alarm devices. By adding the spatial dimension of multiple monitoring points along the pipeline, the system achieves both wide coverage and precise localization through the geometric arrangement of sensors, rather than relying on distance from a single remote alarm.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Device complexity

If manual judgment methods are used to determine gas leakage, then the system complexity is reduced, but the productivity deteriorates due to delayed response and inefficient monitoring

Engineering Contradiction:
Improvesystem complexityVSAvoiddetection response efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent implements an automated feedback loop where alarm devices continuously monitor gas concentrations, transmit data to the central control system, and trigger automatic alerts or valve closures when leakage is detected. This feedback mechanism eliminates manual judgment delays while maintaining manageable system complexity through standardized protocols and automated decision-making algorithms.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The monitoring system performs self-service by automatically detecting leakage conditions, analyzing data, and initiating response actions without requiring continuous human intervention. The central control system autonomously processes alarm signals, determines leakage locations, and can automatically close valves or send notifications, significantly improving response productivity while keeping the system architecture relatively simple.

Inventive Principle:
Principle #25Self-service
