Probe with Integrated Distributor for Leak-Free Filter Monitoring
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
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
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.
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.
3Adaptability or versatility
If flexible tubes are used for connection, then adaptability is improved, but vibrations occur causing seal loosening and leaks
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.
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.
4Quantity of substance
If multiple separate outlet nozzles are used, then sampling points increase, but device complexity increases
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.
