Exhaust vent assembly with selectively removable top
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exhaust vents face difficulties in allowing easy access to the vent channel for cleaning and clog identification due to permanently or semi-permanently attached inhibiting structures, making it hard for users to access the conduit, especially when located on building roofs.
Innovation Solution
An exhaust vent assembly with a selectively removable top wall that can be translated and secured, featuring a mesh screen and rotatable top wall design, allowing easy access to the vent channel while preventing debris and environmental substances from entering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If inhibiting structures (grates, louver slats) are permanently or semi-permanently coupled to the exhaust vent walls, then debris and environmental substances are prevented from entering the conduit, but access to the vent channel for cleaning and maintenance becomes difficult or impossible
Solution Approach 1:
The exhaust vent is divided into separate functional components: a removable top portion and a fixed base portion containing the inhibiting structures. This segmentation allows the top to be removed for maintenance access while the inhibiting structures remain in place to prevent debris entry, resolving the contradiction between protection and accessibility
Solution Approach 2:
The top portion is designed with dynamic characteristics, allowing it to be removed and reattached. This dynamic design enables easy access to the vent channel for cleaning while maintaining the static protective function of the inhibiting structures, solving the access difficulty problem
2Productivity
If the exhaust vent is coupled to the roof of the building structure, then effective venting is achieved, but difficulty in accessing the conduit or vent channel is exacerbated
Solution Approach 1:
By segmenting the exhaust vent into removable top and fixed base portions, the design provides easy access to the vent channel from the roof level without requiring access to difficult-to-reach areas like the attic. The inhibiting structures remain protected in the fixed base while maintenance is simplified through top removal
3Object-affected harmful factors
If a curved or angled cover or top wall is used in the exhaust vent, then rain and environmental substances are redirected away from the conduit, but accessing the conduit or vent channel becomes difficult or impracticable
Solution Approach 1:
The curved or angled top wall is separated into a removable top portion, allowing the protective rain-redirection geometry to be maintained while enabling easy removal for access to the vent channel, eliminating the difficulty caused by the curved structure
Solution Approach 2:
The top wall transitions from a fixed curved structure that impedes access to a dynamically removable component, maintaining its rain-redirection function while allowing easy removal for maintenance activities

AI summary
An exhaust vent assembly with selectively removable top wall that includes an exhaust vent body with a base wall, two opposing sidewalls, a rear wall, and the top wall that is capable of being removed from the sidewalls to provide access to the inside (or vent channel) of the exhaust vent assembly. The top wall is capable of having a closed position with the top wall secured and covering the upper edges of the two opposing sidewalls and with a mesh screen coupled to the exhaust vent body that is capable of preventing animals, certain insects, and other matter from entering the vent channel. The top wall is configured to have an open position with the top wall substantially uncovering the upper edges of the two opposing sidewalls and providing access to the vent channel.
