Solution Overview

Problem

Existing probes for monitoring filter efficiency in safety duct housings suffer from leaks due to numerous outlet ports and flexible tubes, leading to load losses, vibrations, and increased maintenance needs, while also failing to provide complete sampling coverage.

Innovation Solution

A probe with a frame and head design featuring a central rod with integrated ducts and a distributor system, allowing for selective sampling at multiple points without flexible tubes, reducing the risk of leaks and improving structural integrity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple outlet ports are provided in the frame for inserting outlet nozzles, then sampling coverage is improved, but the tightness of the housing deteriorates due to increased critical points for leaks

Engineering Contradiction:
Improvesampling coverageVSAvoidtightness of housing
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

Multiple outlet nozzles are integrated into a single piece, forming one unified component that replaces multiple separate nozzles. This merging eliminates the need for multiple separate insertion points in the housing frame, thereby maintaining housing tightness while preserving comprehensive sampling coverage through the multiple integrated outlets.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single piece contains multiple outlet nozzles that can be selectively connected to different inlet nozzles, providing multi-functional capability. This allows the system to sample from multiple locations while using a single unified interface with the housing, thus maintaining tightness while achieving versatile sampling coverage.

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

2Ease of operation

If flexible tubes are used to connect outlet nozzles to inlet nozzles, then ease of operation is improved, but load losses and vibrations increase

Engineering Contradiction:
Improveease of connectionVSAvoidload losses
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

The flexible tubes are completely removed from the system. Instead of using flexible tubes to connect nozzles, the invention uses a rigid single piece structure with integrated nozzles that are directly connected through internal passages, eliminating the source of load losses and vibrations while maintaining operational simplicity.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The connection function previously performed by flexible tubes is merged into the single piece structure itself, which contains internal passages that directly connect the nozzles. This eliminates the need for separate flexible tube components while maintaining the ability to selectively connect and disconnect sampling lines.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If flexible tubes are used for connection, then adaptability is improved, but vibrations occur causing seal loosening and leaks

Engineering Contradiction:
Improveflexibility of connectionVSAvoidvibrations
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The flexible tubes that cause vibrations are completely extracted from the system. The invention replaces them with a rigid single piece structure that provides structural stability while maintaining adaptability through selective connection of multiple nozzles to different sampling points.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The flexibility and adaptability previously provided by flexible tubes is merged into the design of the single piece itself, which integrates multiple nozzles that can be selectively activated. This provides adaptability without the harmful vibrations caused by flexible tube movement.

Inventive Principle:
Principle #5Merging (Combining)

4Quantity of substance

If multiple separate outlet nozzles are used, then sampling points increase, but device complexity increases

Engineering Contradiction:
Improvenumber of sampling pointsVSAvoidnumber of components
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

Multiple separate outlet nozzles are merged into a single integrated piece containing all nozzles as integral features. This reduces the number of separate components from multiple individual nozzles to one single piece, thereby reducing device complexity while maintaining the ability to sample from multiple points simultaneously or selectively.

Inventive Principle:
Principle #5Merging (Combining)
