Adjustable Blower Tube Attachment for Nozzle Angle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power air blowers lack adjustable length mechanisms and adjustable outlet angles, leading to uncomfortable operator positions and inefficient debris clearing.
Innovation Solution
A universal attachment system for power air blowers, comprising an elongated tube and a bent or curved tube assembly with a lockable length adjustment, allowing the air outlet nozzle to be positioned at an optimal height and angle relative to the ground surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the tubular extension length is fixed, then the device structure is simple, but the operator must bend back in uncomfortable position
Solution Approach 1:
The patent implements a telescoping extension mechanism that allows the tubular extension length to be dynamically adjusted by the operator. The extension can be extended or retracted based on the operator's height and the specific task requirements, transforming a fixed static structure into a dynamic adjustable one. This resolves the contradiction by enabling operator comfort through length adjustment while maintaining relatively simple structure through telescopic design.
Solution Approach 2:
The patent changes the length parameter of the tubular extension from a fixed value to a variable range. The extension can be adjusted to different lengths to accommodate operators of various heights and different working conditions. This parameter change allows the device to adapt to different operational requirements without fundamentally changing the overall device structure.
2Productivity
If the nozzle elevation and orientation are fixed, then the device structure is simple, but effective clearing of debris is difficult
Solution Approach 1:
The patent incorporates an adjustable nozzle assembly that can be positioned at different elevations and orientations. The nozzle can be adjusted vertically and angled to direct airflow at optimal positions for clearing debris from various surfaces including ground level and elevated areas like gutters. This dynamic positioning capability enhances debris clearing efficiency without requiring a completely complex reconfigurable system.
Solution Approach 2:
The nozzle assembly is segmented into adjustable components that can be independently positioned. The separation of the nozzle from the main tubular extension allows for independent adjustment of nozzle elevation and orientation, enabling effective debris clearing while keeping each component relatively simple in design.
3Adaptability or versatility
If the attachment system is not universally adaptable, then the connection structure is simple, but the system cannot be retrofitted to various blowers
Solution Approach 1:
The patent designs the attachment system with universal adaptability features including standard connection interfaces that can interface with various blower types (hand-held, backpack-style, etc.). The attachment system is configured to be compatible with different blower models and configurations, allowing a single attachment design to serve multiple functions across different blower platforms without requiring model-specific customization.

AI summary
An attachment system for a power air blower is disclosed. The attachment system is made to be universally adaptable, connectable, or retrofittable to a wide variety of existing blowers. The attachment system includes an elongated tube and a bent or curved tube. The elongated tube attaches, at one end, to an air outlet of a power air blower and, at the other end, to an air inlet end of the bent or curved tube, which includes a nozzle at the opposite end. The elongated tube and the bent or curved tube cooperate with each other, such as telescopically, so that the attachment system is length-adjustable and the separation between the nozzle and the power air blower is adjustable. The attachment system includes one or more light emitters configured to illuminate an area adjacent to the nozzle.
