Filter assembly cover with integrated sensors
Solution Overview
Problem
Existing filter assemblies with electronic subassemblies require specialized tools and technical knowledge for installation and maintenance, and are prone to static discharge damage due to the location of electronic components within the same enclosure as the subassemblies.
Innovation Solution
A modular filter assembly design featuring a removable cover with integrated sensors, allowing for field upgrades and maintenance without tools, and protecting electronic components from static discharge by enclosing them within a plenum.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If electronic subassemblies are installed in the same enclosure as electronic components, then the equipment can be compact, but the electronic components become susceptible to static discharge damage
Solution Approach 1:
The enclosure is divided into separate compartments: one for electronic components and another for electronic subassemblies. This segmentation allows the equipment to remain compact while protecting electronic components from static discharge by isolating them from potential sources of electrostatic damage during installation and maintenance.
2Reliability
If electronic subassemblies require specialized tools and technical knowledge for installation, then the equipment can be protected from improper handling, but the ease of operation and maintenance deteriorates
Solution Approach 1:
The electronic subassemblies are designed to be removable from the enclosure without requiring specialized tools or technical knowledge. This allows users to easily access, replace, or upgrade subassemblies while maintaining protection against improper handling through designed-in features that guide correct installation procedures.
Solution Approach 2:
The system is designed to allow end-users to perform installation, removal, and replacement of electronic subassemblies themselves without requiring specialized technical expertise. The design includes features that make the process intuitive and self-explanatory, enabling users to service the equipment independently.
3Measurement precision
If sensors are integrated into the cover, then the device complexity increases, but the functionality and measurement capability improve
Solution Approach 1:
Sensors are integrated directly into the cover structure, combining the protective/enclosing function of the cover with the measurement function of the sensors. This merging allows airflow characterization capabilities to be added without requiring separate sensor housings or additional structural elements, thus minimizing the increase in device complexity while maximizing measurement functionality.

AI summary
A filter assembly having a filter module, a fan module, an electronics module including a control system. The fan module inlet and the filter module outlet are laterally spaced apart with their corresponding surfaces extending side by side. A cover is movable between an engaged position engaging the surfaces of the filter and fan modules and a removed position. The cover defines a plenum providing a fluid communication between the filter module outlet and the fan module inlet in the engaged position and directing the flow along a direction different from a direction of the flow through the fan module inlet and filter module outlet. A sensor is located in the plenum and configured to provide information on the flow through the plenum. The sensor communicates with a power source and with the control system at least when the cover is in the engaged position.
