Method and apparatus for providing test ports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clean room ceiling filter systems require additional centerboards that increase manufacturing costs, assembly labor, and material waste, while also compromising airflow uniformity and visual appearance.
Innovation Solution
A filter apparatus with a test port member positioned along the filter media's periphery, allowing for uninterrupted airflow and eliminating the need for separate filter media packs and scrims, thereby reducing assembly labor and material costs while enhancing airflow uniformity and visual integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a centerboard with test ports is used in the filter, then test access is provided, but manufacturing cost and assembly labor increase
Solution Approach 1:
The test port is integrated directly into the filter media pack structure, combining the filtration function and test access function into a single unified component. This eliminates the need for a separate centerboard assembly, thereby reducing manufacturing cost and assembly labor while maintaining test access capability.
Solution Approach 2:
The filter media pack is designed to serve multiple functions: it provides filtration and simultaneously provides test access through integrated test ports. This multi-functionality eliminates the need for separate dedicated test access components, reducing overall system complexity and manufacturing cost.
2Ease of operation
If a centerboard with test ports is used in the filter, then test access is provided, but assembly labor increases
Solution Approach 1:
The test port structure is merged with the filter media pack, creating a single integrated component that requires only one assembly operation instead of multiple separate assemblies. This simplifies the assembly process and reduces labor requirements.
3Ease of operation
If a centerboard is used in the filter, then test ports are provided, but airflow uniformity decreases
Solution Approach 1:
By integrating the test ports directly into the filter media pack structure, the design eliminates the centerboard that disrupted airflow. The test ports are formed as part of the media pack itself, allowing uniform airflow to pass through without obstruction while still providing test access capability.
4Ease of operation
If a centerboard is used in the filter, then test ports are provided, but visual appearance and integration with ceiling deteriorate
Solution Approach 1:
The test ports are integrated into the filter media pack structure, eliminating the need for a separate centerboard that protrudes or disrupts the filter's appearance. This integration allows the filter to maintain a uniform, clean appearance that blends seamlessly with the ceiling while still providing test access functionality.

AI summary
A filter apparatus and method having a test port member (220) in combination with a filter media (40). The test port member may be positioned adjacent the outer periphery of the outer peripheral frame (32) and may be attached to a truncated portion (44) of the filter media. One or more scrim layers (160) may be disposed across one or more sides of the test port member and/or the truncated portion of the filter media. A plug (150) may be inserted into a through port of the test port member.
