Solution Overview

Problem

Existing flame detection systems lack information about the field of view (FOV) and fail to accurately identify critical regions, leading to misalignment and obstacle issues, which compromise the accuracy of flame detection and installation.

Innovation Solution

A system comprising sensors, imaging devices, and processors that capture real-time images, compare them with reference images, and determine misalignment and obstacle information within the FOV by masking IR channels with criticality levels and identifying key points.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single pixel non-imaging detector is used for flame detection, then the system can detect flames from all directions within FOV, but the system cannot provide information about what regions are being viewed or seen

Engineering Contradiction:
Improvedetection coverageVSAvoidFOV region information
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent divides the FOV into multiple zones with different criticality levels and uses multiple imaging devices positioned at different locations to capture images of different regions. This segmentation allows the system to track which specific regions are being viewed by the sensor while maintaining comprehensive detection coverage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces imaging devices as intermediary components that capture visual information about the FOV regions. These imaging devices act as mediators between the non-imaging flame detector and the environment, providing information about what regions are being viewed without interfering with the flame detection function.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If comprehensive FOV monitoring is implemented using multiple imaging devices, then misalignment and obstacle information can be detected, but the system complexity increases

Engineering Contradiction:
Improveflame detection accuracyVSAvoidsystem configuration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The imaging devices serve multiple functions: they capture images for misalignment detection, identify obstacles in the FOV, and provide information about critical regions. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing system complexity while improving reliability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system uses the existing imaging devices and their captured images to self-diagnose misalignment and obstacle conditions. The processors automatically compare images with reference images and generate diagnostics without requiring external intervention, reducing the complexity of manual monitoring and adjustment.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If real-time image comparison with reference images is performed, then misalignment information can be determined, but processing time and computational resources increase

Engineering Contradiction:
Improvemisalignment detection precisionVSAvoidprocessing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies zone-based masking where only specific regions of interest with different criticality levels are processed in detail. By focusing computational resources on critical zones rather than the entire FOV uniformly, the system maintains high measurement precision for misalignment detection while reducing overall processing time.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system performs partial image comparison by focusing on key features and critical zones rather than processing every pixel in the entire image. This partial action approach provides sufficient misalignment detection precision while significantly reducing computational burden and processing time.

Inventive Principle:
Principle #16Partial or excessive action
