Modular Vent Hood Blower Layout for In-Line or External Exhaust
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vent hood blower systems lack flexibility in installation and configuration, limiting their adaptability to various kitchen and commercial applications, as they are typically fixed in a single position and do not efficiently manage the exhaust of gases and vapors across different cooking setups.
Innovation Solution
A modular vent hood kit with a canopy assembly and a removable blower assembly that can be configured in either an in-line or external position, allowing for flexible installation and improved exhaust management by utilizing a main and accessory blower housing with adaptive duct adapters and electrical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed blower system is used, then the structure is simple, but the adaptability to different installation configurations is poor
Solution Approach 1:
The blower system is divided into separate modular components: a canopy assembly, a removable blower assembly, a main blower housing, and an accessory blower housing. This segmentation allows each component to be independently configured and repositioned to achieve different installation configurations (in-line or external) without redesigning the entire system, thus improving adaptability while maintaining manageable complexity through standardized connection interfaces.
Solution Approach 2:
The blower assembly is designed to be selectively removable and repositionable between two configurations: in-line position within the main blower housing and external position within the accessory blower housing. This dynamic reconfigurability allows the system to adapt to different installation requirements while maintaining a relatively simple overall structure through consistent housing and connection designs.
2Adaptability or versatility
If a modular removable blower assembly is used, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The removable blower assembly serves multiple functions by being compatible with both the main blower housing and the accessory blower housing. The same blower assembly unit can be installed in either the in-line configuration (providing exhaust through the main housing) or the external configuration (providing exhaust through the accessory housing), eliminating the need for multiple specialized blowers and reducing overall system complexity despite the modular design.
Solution Approach 2:
The blower assembly is nested within either the main blower housing or the accessory blower housing depending on the desired configuration. The main blower housing contains the blower assembly for in-line applications, while the accessory blower housing contains the same blower assembly for external applications. This nesting approach allows a single blower assembly to serve both configurations without requiring duplicate components.

AI summary
A vent hood kit comprises a canopy assembly having an intake end and an outlet end, a blower housing selectively and alternatively coupled with the exhaust end of the canopy assembly in an in-line position and an external position, a blower assembly disposed within a blower housing and in communication with the intake end in both the in-line and external positions and an exhaust duct adapter of the blower housing is configured to be in communication with the intake end in both the in-line and external positions.
