Support bypass vent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ventilation systems face challenges in bypassing support structures without compromising their structural integrity, particularly due to the need to cut into beams or headers, and the ban on air admittance valves in many regions due to code violations.
Innovation Solution
The development of a support bypass vent with a central body and tapered terminal end portions, featuring adapter ports and screw plates for secure attachment, allowing air to flow around support structures without drilling through them, while maintaining structural stability and being customizable for various applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an air vent is cut into a support structure to traverse from ground to roof, then the air vent can be installed, but the structural integrity of the support structure is compromised
Solution Approach 1:
The air vent system is segmented into separate components: the support structure remains intact while the air vent travels through wall cavities and uses external adapters to connect to ventilation lines, eliminating the need to cut through the support structure
Solution Approach 2:
An intermediary air vent pathway is introduced that travels through wall cavities and uses adapters as mediators to connect ventilation lines on either side of the support structure, avoiding direct penetration of the support structure
2Strength
If air admittance valves are used to bypass support structures, then the structural integrity is maintained, but the valves are banned in most states due to code violations
Solution Approach 1:
Instead of using a valve mechanism that was banned, the invention inverts the approach by using a passive bypass system with adapters that mechanically connect ventilation lines around the support structure, achieving the same functional result through a different, code-compliant mechanism
Solution Approach 2:
The invention creates a functional copy of the air admittance valve's bypass capability using a different mechanism - a passive adapter system that replicates the ventilation function without using the banned spring-loaded valve technology
3Strength
If a support bypass vent is designed to go around support structures, then the structural stability is maintained, but the wall thickness increases significantly
Solution Approach 1:
The air vent pathway transitions from a linear through-wall approach to a three-dimensional path that travels through wall cavities and uses angular adapters to navigate around support structures, effectively adding spatial dimensions to the vent routing
4Length of stationary object
If the central body portion is made less than half inch thick, then the wall thickness is minimized, but the structural strength of the vent itself may be compromised
Solution Approach 1:
The vent system uses composite construction with the central body portion made from high-strength materials that provide sufficient structural integrity even at reduced thickness of less than half inch, while the overall system strength is distributed across multiple components including adapters and mounting hardware

AI summary
A support bypass vent having: a beam pass vent having: central body portion with two opposite ends and a hollow center; a terminal end portion associated with each opposite end of the central body portion; a plurality of screw plates associated with the central body portion; at least one adapter port nested within each terminal end portion; and a ventilation line adapter configured to engage with each terminal end portion by engaging with a corresponding adapter port; wherein each ventilation line adapter is further configured to engage with a corresponding ventilation line such that air is configured to travel through the support bypass vent. By utilizing a support bypass vent with a central body portion having a lesser thickness as part of a ventilation system, the support bypass vent may provide a ventilation pathway around a support structure without significantly increasing the resultant wall thickness covering the support structure.
