An AC filter sensor system comprising a device with sensors and transducers that measure pressure differential within the AC unit, communicating via a mobile application to alert users and suppliers when a filter needs replacement, ensuring timely and efficient filter changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users manually track and change AC filters without a monitoring system, then device complexity is reduced, but filter replacement timing becomes unreliable leading to premature or delayed changes
Solution Approach 1:
The system enables automatic monitoring of filter condition through pressure differential sensors and automated notification to users via mobile applications, eliminating the need for manual tracking and ensuring timely filter replacement based on actual filter status rather than fixed schedules
Solution Approach 2:
The system continuously monitors pressure differential across the filter and provides feedback to users through mobile notifications when the filter reaches replacement thresholds, creating a closed-loop system that automatically tracks and communicates filter status without user intervention
2Reliability
If regular service calls are used to monitor filter status, then filter replacement reliability improves, but service costs increase
Solution Approach 1:
The system performs self-monitoring of filter status using integrated pressure sensors and automatically communicates with users through mobile applications, eliminating the need for paid service calls while maintaining reliable filter replacement timing through continuous automated monitoring
Solution Approach 2:
The system replaces the mechanical/service-call-based monitoring approach with an automated electronic monitoring system using pressure differential sensors, transducers, and wireless communication, substituting human service intervention with automated technological monitoring
3Object-affected harmful factors
If users change filters based on fixed schedules without monitoring, then device complexity is minimized, but indoor air quality deteriorates due to late filter changes
Solution Approach 1:
The system continuously monitors pressure differential across the filter and provides real-time feedback to users through mobile notifications when replacement is needed, ensuring filters are changed based on actual condition rather than fixed schedules, thereby maintaining indoor air quality through timely intervention
Solution Approach 2:
The mobile application serves as an intermediary between the sensor system and the user, translating complex sensor data into simple actionable notifications that prompt users to replace filters at the optimal time, bridging the gap between technical monitoring and user action

AI summary
The present invention relates to an AC filter sensor system that monitors the lifespan of an AC filter. The system is primarily comprised of a device, a mobile application, and a method of use. The device can be placed within an AC unit wherein a sensor and a transducer of the device measure pressure differential within the unit to allow the device to determine when an air filter needs to be replaced. The device then communicates this information to the mobile application, which alerts the user that the filter needs replaced and may also alert a filter supplier who can then ship a filter to the user.
