Articulating assemblies for cleaning tools and methods of use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mop and cleaning tool designs lack flexibility in movement, as they typically allow only limited pivoting motions between the handle and mop head, restricting the range of motion and ease of use.
Innovation Solution
A configurable universal joint system that allows for relative movement of a mop handle and mop head through 360° in a hemisphere, with adjustable axes and reconfigurable settings, enabling pivoting about one or two axes and allowing for easy adjustment between different motion configurations using a U-shaped bracket and fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed rigid connection is used between handle and mop head, then structural simplicity is maintained, but range of motion is limited
Solution Approach 1:
The patent applies dynamics by making the connection between handle and mop head adjustable rather than fixed. The universal joint mechanism allows the system to transition between different motion states (locked vs. unlocked, single-axis vs. dual-axis), enabling the structure to adapt its degrees of freedom based on operational requirements.
Solution Approach 2:
The joint mechanism is segmented into distinct functional components including the U-shaped bracket, sidewalls with complementary surfaces, pivot axes, and locking mechanisms. This segmentation allows each component to perform its specific function independently while contributing to the overall versatile motion capability.
2Adaptability or versatility
If a universal joint allowing 360° motion is implemented, then flexibility is improved, but control precision is reduced
Solution Approach 1:
The patent changes the parameter of motion restriction by providing adjustable limits on the universal joint's range of motion. Through the locking mechanisms and complementary surfaces, the system can transition from allowing full 360° motion to restricting motion to specific arcs or planes, thereby adjusting the parameter of motion freedom to match operational needs.
Solution Approach 2:
The joint mechanism incorporates self-locking features through complementary surfaces and positioning elements that automatically engage at specific orientations. This allows the system to self-regulate its motion control without requiring constant external intervention, maintaining stability when needed while preserving flexibility when required.
3Adaptability or versatility
If adjustable axes and reconfigurable settings are added, then adaptability is enhanced, but device complexity increases
Solution Approach 1:
The U-shaped bracket assembly serves multiple functions: it provides the universal joint mechanism, incorporates the locking features, includes the complementary surfaces for motion restriction, and allows for axis reconfiguration. This multi-functionality reduces the need for separate adjustment mechanisms, thereby limiting the increase in overall device complexity despite enhanced adaptability.
4Ease of operation
If motion is restricted to single plane or arc, then control precision is improved, but ease of operation is reduced
Solution Approach 1:
The system dynamically adjusts its motion constraints based on operational requirements. The user can switch between restricted motion modes (single plane or arc) and unrestricted universal motion modes, allowing the system to be precise when control is needed and versatile when adaptability is needed.
