Livestock Blower Housing Segmentation and Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing livestock blowers are cumbersome, generate excessive noise, do not provide sufficient air volume, especially for larger animals, and inadvertently heat the air, which is undesirable in hot weather, while also having a shortened lifespan due to dirt and debris fouling the motor.
Innovation Solution
A blower apparatus with a blower housing that isolates air from the motor and components, encloses and protects the motor, and uses a cooling system to minimize heat transfer, featuring tangential bypass flow motor fans with electric motors outside the fan housing and a cooling fan to remove heat, along with a Y-shaped conduit and flexible air hose with a reduced nozzle for efficient air delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the motor is located inside the fan housing, then the apparatus is more compact, but the motor is fouled by dirt and debris which shortens its life
Solution Approach 1:
The apparatus is divided into separate compartments: the motor is housed in a motor housing that is physically separated from the fan housing by a motor housing partition. This segmentation allows the motor to be protected from dirt and debris while maintaining a compact overall design, as the partition creates distinct functional zones within the apparatus.
2Quantity of substance
If air is drawn directly through the blower housing, then the air volume is sufficient, but the air is heated by the motor which is undesirable in hot weather
Solution Approach 1:
The motor is extracted from the air path by placing it in a separate motor housing compartment. Air is drawn through the fan housing and delivered to animals without passing through or contacting the motor, thereby preventing heat transfer to the air while maintaining sufficient air volume for cooling and grooming purposes.
3Reliability
If a separate motor housing partition is added to protect the motor, then the motor is protected from dirt and debris, but the device complexity increases
Solution Approach 1:
The housing is segmented into distinct compartments (fan housing and motor housing) separated by a motor housing partition. This segmentation provides effective motor protection while maintaining relative simplicity, as the partition is an integrated structural element that creates functional zones without requiring complex additional components or mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides cooler air, reduces noise, protects the blower components, increases apparatus lifespan, and effectively blows air onto animals for cooling, drying, and grooming, while maintaining a compact and efficient design.
Implementation Method 1
A cooling fan is provided at one of the blower housing cooling air inlet opening or blower housing cooling air outlet opening for drawing air into the blower housing interior space through the blower housing cooling air inlet and forcing air out from within the blower housing interior space through the blower housing cooling air outlet opening, whereby heat generated by the blower unit is removed from the blower housing interior space and the blower unit is cooled.

AI summary
A livestock blower apparatus for blowing air through a flexible hose onto an animal. A pair of blower units are enclosed within an interior space of a housing. The blower units are adapted to draw air through housing inlet openings and force it through a Y-shaped conduit out through a housing outlet opening without the air coming in contact with the housing interior space. A cooling fan is provided at a housing cooling inlet opening and blows air into the housing interior space. Another cooling fan is provided at a housing cooling outlet opening and draws/blows air out from within the housing interior space. The blower units are thereby protected from the elements and noise generated by them is muffled by the housing, and the blower units are cooled for minimizing the heat that may be transferred to the air being blown onto the animal.
