Leaf Blower Handle-Mounted Light for Low-Light Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing leaf blowers lack a built-in light source, making it difficult for users to effectively operate in low-light conditions, leading to inefficiencies and discomfort, especially for professionals working early in the morning or evening.
Innovation Solution
An illuminated leaf blower with a pivotally securable handle-mounted light, powered by a battery, allowing for adjustable positioning and ergonomic control, enabling the user to direct airflow and illumination simultaneously without needing external light sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a flashlight or headlamp is used to illuminate the work area, then the user can see in low-light conditions, but the user's hands are occupied or the device becomes cumbersome
Solution Approach 1:
The patent combines the light source with the leaf blower handle, integrating two separate functions (illumination and leaf blowing) into a single unified device. The light is mounted on the handle assembly, allowing it to move with the handle while maintaining a fixed position relative to the blower tube, enabling hands-free operation with both hands available for other tasks
2Device complexity
If the light is fixed on the handle, then the structure is simple, but the light cannot be positioned optimally for different users
Solution Approach 1:
The patent implements an adjustable and repositionable light mounting system that allows the light to be moved to different positions on the handle assembly. The light can be repositioned along the handle tube and secured at various locations, enabling different users to customize the light position to their ergonomic needs while maintaining a relatively simple overall structure
3Illumination intensity
If the light is positioned to illuminate the airflow area, then the work area is well-lit, but the switch becomes difficult to access
Solution Approach 1:
The patent positions the light switch on the rearward haunch of the head piece, utilizing the three-dimensional space of the handle assembly to place the switch in a location that is easily accessible to the user's thumb while the light itself is positioned forward to illuminate the airflow area. This spatial separation allows both functions to operate optimally without interfering with each other
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Provides effective illumination of the airflow area, enhancing operational efficiency and comfort by allowing hands-free use of the blower, with a longer-lasting power source that reduces the need for frequent battery changes.
Implementation Method 1
The light is powered by a battery

AI summary
An illuminated leaf blower having a light disposed upon a handle, the handle disposed upon a pipe section of a blower tube at an angle deviant from the perpendicular by means of a pivotally securable attachment member, the attachment member disposed upon a lockable collar, said lockable collar securably moveable along the pipe section to position the handle as desired for a particular person wielding the device, the handle having a switch disposed on a rearward haunch of a head piece, said head piece disposed atop the handle configured to be ergonomically accessed by means of a thumb of the person wielding the device, whereby the light selectively illuminates an area over which an airflow from the illuminated leaf blower is directed.
