Quick-Connect Flex Duct Adapter for Reliable Air Leak Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for sealing air vents in air duct systems during energy audits are inefficient, leading to false leak readings and hindering construction processes due to the weight and permanence of existing solutions, often requiring two technicians and causing time and monetary waste.
Innovation Solution
A register adapter system with a flange adapter, cylindrical portion, support member, and quick-release latches that allows for easy attachment and detachment of flex ducts, creating a secure airtight seal without the need for permanent attachment, enabling single-person operation and reducing the risk of false readings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If grill mask tape is used to attach the flange to the register grill, then the flex duct can be held in communication with the air flow measurement system, but the tape loosens over time causing false air leak readings
Solution Approach 1:
A register adapter is introduced as an intermediary component between the register grill and the flex duct. The adapter includes a flange with attachment means (such as clips, latches, or snap-fit mechanisms) that securely connect to the register grill without relying on adhesive tape. This intermediary device maintains a stable, permanent connection throughout the testing process, preventing the loosening issue that causes false readings.
Solution Approach 2:
The mechanical attachment system replaces the adhesive tape mechanism. Instead of relying on the chemical bonding and mechanical adhesion of grill mask tape, the invention uses mechanical fastening elements such as clips, latches, or snap-fit features that provide consistent, reliable attachment. This mechanical system maintains constant contact pressure and secure positioning without degrading over time like adhesive materials.
2Reliability
If the flex duct is permanently attached to the register grill, then the air leak testing can be performed, but it hinders construction workers and causes time waste when removal is needed
Solution Approach 1:
The attachment system transitions from a static permanent bond (adhesive tape) to a dynamic, reversible mechanical connection. The register adapter incorporates movable attachment elements such as spring-loaded clips, latches, or snap-fit mechanisms that can be easily engaged and disengaged. This dynamic system maintains secure attachment during testing but allows rapid removal when construction or modifications are needed, eliminating the trade-off between stability and ease of removal.
3Strength
If two technicians are used to remove the register grill, then the grill can be removed safely, but it increases time and monetary costs
Solution Approach 1:
The system is segmented into separate functional components: the register adapter remains attached to the register grill while the flex duct and air flow measurement system are detached. This segmentation allows the heavy register grill to remain supported and stationary during flex duct removal, eliminating the need for a second technician to hold the grill. The adapter-flange connection maintains structural integrity independently, enabling single-person operation for flex duct repositioning.
