In Situ Filter Testing With Virtual Scan Data Trimming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter testing systems fail to account for false readings caused by airborne particles generated from sources unrelated to the filter efficiency, leading to inaccurate test results due to physical activation members and limited graphical user interfaces on handheld probes.
Innovation Solution
Implementing virtual activation members and icons on handheld scanning probes and base units, allowing operators to erase or discount portions of the scan affected by irrelevant particles, with pop-up confirmations and super capacitors to prevent data loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical activation members are used on handheld probes, then the device can be operated, but the number of activation members is limited and the interface is basic
Solution Approach 1:
The patent replaces physical activation members with virtual icons displayed on a graphical user interface. These virtual icons replicate the function of physical buttons but provide additional capabilities such as contextual menus, customizable interfaces, and integrated guidance, thereby improving ease of operation without proportionally increasing device complexity
Solution Approach 2:
The patent transitions from a one-dimensional physical button interface to a two-dimensional graphical interface with multiple icons, menus, and visual guidance elements. This dimensional expansion allows for richer interaction capabilities and more comprehensive functionality within the handheld device
2Measurement precision
If filter scanning is performed continuously, then complete data is collected, but false readings from irrelevant particles cause inaccurate test results
Solution Approach 1:
The patent performs preliminary actions by establishing baseline scan data before potential contamination events occur. The system can identify and exclude false readings from the final results by comparing against expected patterns, thereby maintaining measurement precision while filtering out unreliable data points
Solution Approach 2:
The patent implements feedback mechanisms where the system continuously monitors scan data for anomalies and provides real-time guidance to operators. When false readings are detected (e.g., from particles generated by operator actions), the system can alert the operator and allow for corrective actions, ensuring test result validity
3Loss of information
If handheld probe is used without super capacitor, then device is simpler, but data may be lost during operation
Solution Approach 1:
The patent incorporates a super capacitor that provides a cushion of stored energy to maintain operation during brief power interruptions or at critical moments when data needs to be preserved. This beforehand cushioning ensures data integrity without requiring a complex continuous power supply system
Solution Approach 2:
The super capacitor acts as an intermediary energy storage device between the main power source and the handheld probe's data processing systems. It bridges power gaps and ensures continuous data collection and storage even when the main power source is unavailable, thereby preventing information loss
Data Source
AI summary
A preferred form of the invention is directed to a system and method used to test filters in situ. The system preferably includes a base unit and a handheld probe operably associated with the base unit. The probe is configured to be deployed adjacent the filter being tested while the filter is located in an operating position. The handheld probe and/or base unit can be provided with a virtual or physical trim/rewind activation member to enable the user to erase scan data that the user knows is not reflective of filter leakage or filter efficiency or lack thereof of the filter being tested. The handheld probe and/or base unit can be provided with one or more interactive screens or graphical user interfaces including one or more virtual activation icons as opposed to physical activation members for performing numerous different functions associated with testing a filter in situ.
