Elbowed Blower Extension Pipe for Underside Debris Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional leaf blowers are not designed to effectively clean the underside of wheeled outdoor equipment, such as lawn mowers, as they typically blow air directly toward or parallel to the ground, making it difficult to remove debris from these areas.
Innovation Solution
A tubular extension pipe assembly with a reduced tapered angle end fitting that allows the air stream to be directed upward, combined with a stabilizing handle and secure connecting means, enabling the blower to reach under equipment and clean debris from hard-to-reach areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional blowers blow air directly toward or parallel with the ground, then the blower is easy to operate, but it cannot effectively clean the underside of wheeled equipment
Solution Approach 1:
The patent introduces a new spatial dimension by positioning the blower at ground level and directing air upward at a 45-60 degree angle, rather than blowing parallel to the ground. This dimensional change allows the air stream to reach underneath wheeled equipment from a previously inaccessible angle, simultaneously maintaining ease of operation and improving cleaning effectiveness
2Productivity
If the blower is positioned to reach under equipment, then cleaning effectiveness improves, but the operator loses stability and control
Solution Approach 1:
The patent employs the operator's body weight as a counterbalance to the blower's weight. By positioning the blower at ground level and using the operator's standing position as a stable base, the system creates a balanced configuration where the operator's weight compensates for the blower's positioning, maintaining stability while achieving effective cleaning underneath equipment
3Device complexity
If conventional blowers are used, then the device structure is simple, but it cannot access hard-to-reach areas under equipment
Solution Approach 1:
The patent achieves enhanced accessibility without increasing device complexity by changing the operational dimension from ground-level horizontal blowing to upward vertical blowing at 45-60 degree angles. This simple positional and angular adjustment allows the existing blower structure to reach previously inaccessible areas underneath wheeled equipment

Function Achieved in This Case
Facilitates safe and efficient cleaning of underside debris, reducing labor and safety risks, extending equipment life, and preventing the spread of contaminants, while being economically adaptable to existing leaf blower models.
Implementation Method 1
introduce beneath the underside of wheeled outdoor equipment and operated for blowing air upwardly to clean debris from the underside
Data Source
AI summary
A method of cleaning an underside of wheeled outdoor equipment includes attaching a blower extension pipe assembly to a power blower and positioning the extension pipe across the ground and under the equipment to be cleaned. The blower extension pipe includes an elbow end fitting with a blow-off opening that is directed to the underside of the equipment. The blower is operated to direct air through the blower extension pipe and against the underlying surface of the equipment to remove debris therefrom.
