Push Broom Bracket Assembly for Reversible Handle Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional push broom handle connections tend to loosen and rotate during use, necessitating improved securement and ease of detachment for maintenance and extended bristle life.
Innovation Solution
A bracket assembly comprising first and second bracket pieces with a locking nut that securely attaches the handle to the broom head, allowing reversible positioning and easy assembly/disassembly, using angled bracket pieces and flanges for enhanced stability and support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a threaded handle connection is used in conventional push brooms, then the handle can be detached for shipping and handle reversal, but the handle tends to rotate and loosen during use
Solution Approach 1:
The bracket assembly is divided into separate components: a bracket body attached to the broom head and a detachable handle portion. This segmentation allows the handle to be easily removed and reattached while maintaining a secure connection during use, resolving the contradiction between ease of detachment and connection stability.
Solution Approach 2:
The bracket assembly incorporates a dynamic locking mechanism that transitions from a locked state during use to an unlocked state for detachment. The design allows the handle to be firmly secured during sweeping operations while enabling easy removal when needed, addressing both reliability and ease of operation requirements.
2Reliability
If a fixed bracket position is used, then the handle connection is stable, but the handle cannot be reversed to extend from the front face of the broom head
Solution Approach 1:
The bracket assembly is designed with multi-functionality, serving both as a stable connection point and as a reversible mounting system. The bracket can accommodate the handle in multiple positions (extending from front or back face), providing versatility while maintaining connection stability through its robust design.
Solution Approach 2:
The bracket assembly enables inversion of the handle position, allowing the handle to extend from either the front or back face of the broom head. This inverted positioning capability is achieved through the symmetrical or adaptable design of the bracket mounting system, resolving the contradiction between stability and flexibility.
3Ease of manufacture
If threaded fastening is used for handle attachment, then assembly is simple, but the connection loosens and requires frequent tightening
Solution Approach 1:
The bracket assembly incorporates a self-locking or self-tightening mechanism that maintains the handle connection without requiring periodic tightening. The design includes features such as friction locks, deformed threads, or elastic elements that automatically maintain secure fastening, eliminating the need for user intervention and extending connection durability.
Solution Approach 2:
The bracket assembly uses a permanent or long-lasting fastening mechanism that eliminates the need for repeated tightening and adjustment. The design incorporates elements that maintain their fastening force over time, effectively discarding the need for maintenance and recovering the initial secure connection state throughout the product lifecycle.

AI summary
A cleaning apparatus includes a bracket assembly for securely attaching a handle to a block. The bracket assembly aids in securing the handle in a fixed position during use so that the handle will not loosen and/or disengage with use. The bracket assembly may include one or more flanges for engaging multiple sides of the block. The handle and the bracket assembly may be configured to allow the handle to be reversed so that it extends first from the back face of the block and then from the front face of the block.
