Positive Pressure Blower Frame for Sideways Wheel Maneuvering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Positive pressure blowers used in firefighting are difficult to maneuver and store due to their wheel orientation, which is parallel to the air flow, making them hard to move sideways and insert/remove from narrow compartments on emergency vehicles, potentially causing damage and wasting time.
Innovation Solution
A support frame with wheels mounted perpendicularly to the air flow, allowing the blower to be tilted and moved like a wheelbarrow, facilitating easy sideways movement and insertion/removal from compartments.

Engineering Contradiction Analysis
1Productivity
If wheels are mounted for forward-backward movement, then the blower can be moved easily in that direction, but it cannot be easily placed into or removed from side storage compartments
Solution Approach 1:
The patent inverts the conventional wheel orientation by mounting wheels perpendicular to the air flow direction instead of parallel. This allows the blower to be tilted and moved sideways like a wheelbarrow, enabling easy insertion and removal from narrow compartments while maintaining forward-backward mobility through tilting motion
Solution Approach 2:
The patent implements dynamic movement capability by allowing the blower to be tilted and maneuvered in multiple directions. The wheels are positioned to enable both forward-backward rolling and sideways tilting motion, providing adaptive mobility that responds to different operational needs such as compartment loading or open-area deployment
2Volume of moving object
If the blower is designed to fit into narrow compartments, then it can be stored on emergency vehicles, but it becomes difficult to maneuver at the fire scene
Solution Approach 1:
The patent implements dynamic movement capability by allowing the blower to be tilted and maneuvered in multiple directions. The wheels are positioned to enable both forward-backward rolling and sideways tilting motion, providing adaptive mobility that responds to different operational needs such as compartment loading or open-area deployment
Solution Approach 2:
The patent adds a tilting dimension to the movement capability. By positioning wheels at lower corners and allowing the frame to tilt, the blower gains a rotational degree of freedom that enables sideways movement and easy compartment access without compromising its compact form factor for storage

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.
