Push Broom Handle Bracket for Anti-Rotation Thread Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Push broom handles tend to rotate relative to the broom block during use, loosening the threaded connection and making the tool difficult to control, with existing solutions either damaging the handle or providing inadequate stability.
Innovation Solution
A broom bracket with two braces, each comprising an elongated extension rod, a block connector, and a handle strap with a curved portion featuring teeth along a chord of the handle, forming a collar that inhibits rotation by providing high friction engagement without damaging the handle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a threaded connection is used to attach the broom block to the handle, then the connection can be easily assembled and disassembled, but the handle rotates during use causing the connection to loosen
Solution Approach 1:
The bracket is divided into two separate braces that wrap around the handle independently, with each brace providing partial stabilization. This segmentation allows the bracket to maintain a secure grip on the handle while distributing the stabilizing force across multiple contact points, preventing rotation without compromising assembly ease.
Solution Approach 2:
The bracket is designed to wrap around and enclose the handle, with the two braces forming a collar-like structure that nests around the cylindrical handle. This nesting configuration provides continuous contact around the handle circumference, preventing rotation while maintaining easy assembly through simple wrapping and fastening.
2Stability of the object's composition
If a bracket with rigid connection is used to prevent rotation, then the handle stability improves, but the handle may be damaged due to its small diameter
Solution Approach 1:
The bracket uses thin, flexible braces that wrap around the handle rather than rigid structures that clamp onto it. These flexible braces conform to the handle's small diameter and circular cross-section, providing stabilization through friction and geometric constraint rather than high clamping forces that could damage the handle.
Solution Approach 2:
The bracket is designed with curved braces that follow the circular cross-section of the cylindrical handle. This curvature allows the bracket to engage the handle's round shape effectively, distributing contact forces around the circumference and preventing rotation without creating stress concentration points that could damage the handle.
3Reliability
If the bracket provides strong friction engagement to inhibit rotation, then the connection stability improves, but the attachment and detachment process becomes more difficult
Solution Approach 1:
The bracket employs friction-based engagement that is dynamic in nature - sufficient friction is generated during normal use to prevent rotation and maintain stability, while the same friction allows for easy attachment and detachment when deliberate force is applied. The flexible braces can be easily opened and closed around the handle, providing strong engagement during use but simple release when needed.
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
The bracket effectively prevents rotation of the handle relative to the broom block, maintaining a secure connection and reducing wear on the threaded joint, while allowing for easy attachment and detachment without damaging the handle.
Implementation Method 1
The curved portion includes at least one tooth that extends a length along a chord of a hemicircle defined by the curved portion... providing high friction engagement without damaging the handle
