Adaptive Exhaust Vent With Pivoting Damper for Debris Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional exhaust vents fail to effectively shield conduits from obstruction and are not adaptable to varying conduit sizes, limiting their usability in different structures.
Innovation Solution
An adaptive exhaust vent system comprising a base member with a raised flange, a removable vent adapter, and a pivoting damper, which includes a substantially hollow housing with a counterbalance to maintain fluid communication and prevent debris entry, accommodating various conduit sizes through separable components and sealing elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional exhaust vents are used, then they provide basic exhaust function, but they fail to effectively shield conduits from obstruction and are not adaptable to varying conduit sizes
Solution Approach 1:
The exhaust vent system is divided into multiple components: a base member with a raised flange, a removable vent adapter, and a pivoting damper. This segmentation allows each component to perform its specific function independently while working together as a complete system, enabling adaptability to different conduit sizes through the removable adapter while maintaining reliable shielding through the integrated damper.
Solution Approach 2:
The pivoting damper is designed to rotate between an open position (allowing exhaust flow) and a closed position (shielding the conduit opening). This dynamic movement enables the vent to adapt to different operational states - venting when needed and shielding when not in use - thereby resolving the contradiction between providing basic exhaust function and maintaining shielding effectiveness.
2Adaptability or versatility
If conventional exhaust vents are used, then they provide basic exhaust function, but they may not be usable in various structures or with varying conduit sizes
Solution Approach 1:
The base member with its raised flange is designed as a universal component that can accommodate different conduit sizes through the interchangeable vent adapters. The standardized base member can be installed in various structures while different adapters are attached to match specific conduit dimensions, providing universality without sacrificing ease of installation.
Solution Approach 2:
The removable vent adapter acts as an intermediary component between the standardized base member and various conduit sizes. This mediator allows the base member to remain universal while adapting to different conduit dimensions, simplifying installation by separating the permanent mounting component from the size-specific adapter.
3Object-affected harmful factors
If a pivoting damper is added to provide shielding, then debris prevention is improved, but device complexity increases
Solution Approach 1:
The pivoting damper is designed to be self-operating through counterbalance mechanics that allow it to rotate freely between open and closed positions. The counterbalance mechanism provides automatic positioning - the damper opens when exhaust flow is needed and closes when not in use - without requiring external control systems, motors, or complex actuation mechanisms, thereby maintaining simplicity despite the added shielding function.

AI summary
Provided is an exhaust vent for venting air including a base member configured to be secured to a structure. The base member may define an opening in fluid communication with an exhaust conduit of the structure and a raised flange disposed around the opening. The exhaust vent may also include a removable vent adapter, wherein the adapter is configured to connect to the raised flange and maintain fluid communication between the opening and the exhaust conduit. A substantially hollow housing may be attached to the base member and configured to cover the opening of the base member and maintain fluid communication between the opening and an exterior of the housing. A pivoting damper may also be disposed within the substantially hollow housing configured to rest atop the opening of the base member when in a closed position.
