Extension-Pole Air Blower With Rotating Nozzle for Gutter Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air blower devices for cleaning rain gutters and elevated surfaces often require multiple extension tubes with no other purpose, reduce air velocity due to distance from the blower, and struggle to navigate gutter hangers effectively.
Innovation Solution
A portable air blower device with a battery-powered, ovoid shape secured to the upper end of a length-adjustable extension pole, featuring a selectively rotatable air discharge nozzle and an on/off push button switch, allowing for easy movement along gutters and overhead structures while maintaining air velocity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If multiple extension tubes are used to reach elevated surfaces, then the cleaning device can access higher areas, but the air velocity is reduced due to the distance air must travel
Solution Approach 1:
The air blower is divided into modular components: a telescopic extension pole with multiple segments that can be adjusted in length, and a separate air blower unit that can be attached at various positions. This allows the pole to be extended to reach elevated surfaces while keeping the air blower close to the gutter for maintaining air velocity.
Solution Approach 2:
The air blower unit is positioned in a different spatial dimension relative to the extension pole - it attaches laterally to the pole rather than being at the distal end. This allows the pole to extend vertically to reach gutters while the air blower remains positioned close to the target area, solving both the reach and air velocity problems simultaneously.
2Length of stationary object
If multiple extension tubes with elbows are used to reach gutters, then the device can access elevated surfaces, but the device complexity increases
Solution Approach 1:
Multiple extension tubes and elbows are merged into a single telescopic extension pole with integrated joint mechanisms. The pole contains multiple telescoping segments that can extend and retract, replacing the need for separate extension tubes and elbow connectors while maintaining the ability to reach elevated gutters.
Solution Approach 2:
The telescopic extension pole serves multiple functions: it provides the necessary length to reach elevated gutters, contains integrated joints for navigating around obstacles, and offers adjustable positioning. This multi-functional design replaces several separate components with a single versatile tool.
3Weight of moving object
If the air blower is positioned far from the gutter to reach elevated surfaces, then the device can access higher areas, but the air velocity is reduced
Solution Approach 1:
The air blower unit is designed with dynamic positioning capabilities through the telescopic pole, allowing it to be moved closer to or farther from the gutter as needed. The pole segments can be extended or retracted to optimize the distance between the air blower and gutter, maintaining air velocity while providing positioning flexibility for different gutter heights.
