Clamp-On Auxiliary Handle for Long-Handled Tool Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of long-handled tools like shovels, brooms, and rakes must repeatedly bend over to lift and control the tools, exceeding a comfortable range of motion.
Innovation Solution
A clamp structure with a first and second channel member, each with a V-shaped closed side, and a handle extending transverse to the axis, allowing secure attachment to the tool handle via pivoting female and male members and wing nuts for easy handling without bending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users hold long-handled tools directly, then tool control is possible, but users must repeatedly bend over exceeding comfortable range of motion
Solution Approach 1:
The patent introduces a vertical dimension by positioning the attachment body above the handle rather than along its length. The handle extends horizontally from the body, creating a perpendicular arrangement that elevates the control point to a comfortable height, eliminating the need for bending while maintaining tool control.
2Ease of operation
If a clamp structure is added to attach tools, then ease of operation improves, but device complexity increases
Solution Approach 1:
The patent combines multiple functions into a single integrated attachment body that simultaneously provides clamping, positioning, and handle support. The body integrates the clamp mechanism, pivot points, and handle mounting into one unified structure, reducing overall system complexity while maintaining operational benefits.
Solution Approach 2:
The clamp structure incorporates self-adjusting features where the clamp members automatically position and secure the tool handle through pivot motion and friction engagement. The wing nuts provide self-locking capability, eliminating the need for additional fastening mechanisms or complex adjustment procedures.
3Reliability
If secure clamping is achieved with multiple clamp structures, then reliability improves, but manufacturing complexity increases
Solution Approach 1:
The patent divides the clamping function into separate first and second clamp structures that can be manufactured independently and then assembled. Each clamp member is a discrete component with standardized pivot points and fastening mechanisms, allowing for modular production and simplified quality control while providing redundant securing points for enhanced reliability.
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
Enables users to control long-handled tools without bending over, providing secure and easy attachment and detachment, with a robust and lightweight design.
Implementation Method 1
a threaded fastener that extends through the male member transverse to the first male member axis; and a first wing nut threaded to the threaded fastener
Implementation Method 2
a first female member adjacent to a first channel member comprising a first channel closed side along an axis to receive a member along the axis, the first female member pivots about a first female member axis parallel to the axis
