Positive Pressure Blower Frame for Side-Compartment Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing positive pressure blowers are difficult to move sideways due to wheel orientation, making them challenging to place into or remove from side storage compartments on emergency vehicles, which can result in damage and wasted time.
Innovation Solution
A support frame with wheels mounted at the lower corners, oriented perpendicular to the airflow, allowing the frame to be tilted and moved sideways like a wheelbarrow, facilitating easy insertion and removal from side compartments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wheels are mounted perpendicular to the sideways movement direction, then the blower can be placed into side compartments, but the wheels may be damaged and time is wasted
Solution Approach 1:
The patent changes the wheel orientation to be perpendicular to the airflow direction, which enables the blower to be tilted and rolled sideways without damaging the wheels. The wheels are positioned to bear the weight during sideways movement, preventing damage that would occur with conventional mounting orientations.
2Volume of moving object
If the blower is stored sideways in a narrow compartment, then it fits the emergency vehicle storage space, but the conventional wheel orientation makes removal difficult and time-consuming
Solution Approach 1:
The patent orients the wheels perpendicular to the airflow direction, allowing the blower to be tilted onto its side and rolled out of narrow storage compartments quickly and easily. This inverted orientation enables the blower to be removed without dragging or manual lifting, significantly reducing retrieval time while maintaining compact storage capability.

AI summary
The present invention provides support frames for positive pressure blowers having one or more wheels mounted at a lower corner of the frame, wherein the wheels are mounted to roll in a direction that is perpendicular to the flow of air through the blower. This sideways orientation of the wheels allows a frame carrying a blower to be easily moved from side to side, such as when placed into or removed from a side compartment on an emergency vehicle, and allows such a frame carrying a blower to be easily tilted, turned and rolled around at the scene of a fire in much the same manner as a wheelbarrow. Embodiments of the invention may include an upper handle or grip which allows a user to control the frames by tilting and rolling them around on the wheels. Embodiments of the invention may include a support bracket for holding a battery or other power supply.
