Intake Particle Detection Verification Using Multi-Opening Exit Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for verifying the functionality of intake particle detection systems are time-consuming and economically inefficient, particularly due to the limited significance of transit time measurements at only the last intake opening, and often require additional components like valves, increasing costs and susceptibility to malfunctions.
Innovation Solution
A method involving directing a test fluid flow from a generator towards intake openings, measuring actual exit times using a timer, and comparing them with pre-defined target exit times or ranges stored on a data carrier, allowing comprehensive verification of the system's components, including filters, fittings, and intake openings, with reduced time and increased informative value.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If transit time measurements are performed only at the last intake opening, then the measurement process is simplified, but the verification significance is reduced and time consumption increases
Solution Approach 1:
The patent divides the verification process into multiple measurement points along the pipe branch. Instead of measuring only at the last intake opening, the method segments the measurement locations to include intermediate intake openings, thereby reducing total verification time while maintaining comprehensive system assessment
Solution Approach 2:
The patent introduces a test fluid with known properties and predetermined target exit times before actual operation. By establishing expected transit times in advance for multiple measurement points, the system enables rapid comparison and verification without time-consuming repeated measurements
2Reliability
If additional components like valves are added to the system, then functionality verification capability is improved, but device complexity and susceptibility to malfunctions increase
Solution Approach 1:
The patent employs the existing fluid conduction system components (pipes, intake openings, flow means) to perform the verification function. The test fluid flows through the existing system without requiring additional valves or complex test equipment, allowing the system to verify itself using its own operational components
Solution Approach 2:
The patent introduces a test fluid as an intermediary substance to carry verification information through the system. This test fluid acts as a mediator that interacts with existing system components to reveal their functionality without requiring physical modification or additional mechanical components
3Measurement precision
If comprehensive verification of all components is performed, then verification accuracy is improved, but time consumption and economic efficiency worsen
Solution Approach 1:
The patent changes the verification approach from physical inspection of each component to measuring transit time parameters of a test fluid. By monitoring temporal parameters (exit times) at multiple points, the system achieves comprehensive verification of filters, fittings, and intake openings through a single fluid flow test, significantly improving economic efficiency

Function Achieved in This Case
The method significantly reduces verification time while providing comprehensive and economical assessment of the intake particle detection system's functionality, detecting impairments such as leaks, blockages, or malfunctions across all intake openings, and facilitating automated or manual detection.
Implementation Method 1
a test fluid is introduced via the test fluid line and/or the test fluid connection into the fluid conduction system, wherein a test fluid flow is generated within the at least one pipe and/or hose line
Implementation Method 2
a flow means for generating a fluid sample flow within the at least one pipe and/or hose line, wherein the fluid sample flow is directed from the one or more intake openings in the direction of the detection unit
Data Source
AI summary
A method for verifying the functionality of an intake particle detection system (100), in particular an intake fire detection system. A test fluid flow (220) within at least one pipe and/or hose line (110, 120) is directed in such a way that the test fluid (210) from the test fluid generator (230) enters the fluid conduction system (110, 120, 130) and exits from the one or more intake openings. Respective actual exit times from the introduction and/or entry of the test fluid (210) into the fluid conduction system until the exit of the test fluid (210) from a respective intake opening are detected by means of a timer. Detected actual exit times are compared with a data set (261) which is stored on a data carrier (160, 260), and which comprises target exit times and/or target exit time ranges associated with the respective intake openings (A, B, C, . . . X).
