System and method for improving air-quality of a space serviced by an exit register
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional HVAC air vent systems fail to effectively filter and disperse air due to dirty ducting systems, leading to indoor air quality issues and health risks, especially for children and the elderly, as they often require difficult maintenance and result in persistent airflow patterns that stir up dust and contaminants.
Innovation Solution
A retrofit register vent air filter cover system with a magnetic, adjustable metal frame and secondary air filtration system that allows easy access and maintenance of ducting systems, featuring a filter appliance with angled fins for improved airflow and filtration, and adjustable magnets for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional HVAC air vent systems are used, then the system structure is simple and easy to manufacture, but the air filtration effectiveness is poor and indoor air quality deteriorates
Solution Approach 1:
The patent implements a nested structure where the magnetic register cover is placed inside the existing register, the filter appliance is nested within the register cover, and the duct access door provides access to the ducting system. This nested arrangement allows multiple functional layers (filtration, magnetic attachment, duct access) to be integrated within the confined space of the existing register assembly, improving air filtration effectiveness without requiring complete system replacement or excessive structural complexity
Solution Approach 2:
The patent introduces a magnetic register cover as an intermediary component between the existing register and the filter appliance. This magnetic cover serves as a mediator that holds the filter in place through magnetic attraction, allowing the filter to be securely positioned without mechanical fasteners. The intermediary magnetic mechanism enables effective filtration while maintaining system simplicity and ease of installation
2Ease of operation
If traditional exit registers are used, then the device complexity is low, but the maintenance difficulty increases and air quality worsens due to dust circulation
Solution Approach 1:
The patent extracts the filter appliance as a separate, removable component from the register system. The filter can be easily removed and replaced by simply taking it out from the magnetic register cover without disassembling any permanent components. This extraction approach allows maintenance personnel to service the filter independently, significantly improving maintenance ease while adding minimal complexity to the overall system
Solution Approach 2:
The magnetic register cover enables self-service maintenance by allowing users to easily attach and remove filters without requiring tools or technical expertise. The magnetic attachment mechanism automatically secures the filter in place when brought near the register, and removal is achieved by simply pulling it away. This self-service capability improves ease of operation while keeping the device complexity low
3Object-affected harmful factors
If conventional air vents are used, then the system is simple, but harmful factors increase due to persistent airflow patterns stirring up dust and contaminants
Solution Approach 1:
The patent implements preliminary filtration by placing the filter appliance in the register cover before air enters the living space. This preliminary action of filtering air at the register level, rather than relying solely on distant HVAC filters, prevents dust and contaminants from being stirred up and circulated by airflow patterns. The filter is positioned to intercept particles before they can be dispersed into the room, improving air quality while maintaining relatively simple system architecture
