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 options, as they often restrict the range of motion between the handle and mop head to a single axis or plane, limiting the user's ability to maneuver effectively in various cleaning scenarios.
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 pivot configurations, enabling pivoting about one or two axes and allowing for easy reconfiguration between different motion modes via simple component adjustments or fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-axis or single-plane movement mechanism is used to connect the handle and mop head, then the device complexity is reduced, but the adaptability and versatility of the cleaning tool are limited
Solution Approach 1:
The joint system allows dynamic reconfiguration between different movement modes (single-axis, dual-axis, 360-degree rotation) through adjustable components. The user can change the operational characteristics of the joint by repositioning adjustable elements, enabling the system to adapt its degrees of freedom based on cleaning requirements without being fixed in a single configuration
Solution Approach 2:
The joint assembly is designed to perform multiple functions: it can operate as a single-axis hinge, a dual-axis universal joint, or a 360-degree rotating connector. This multi-functionality is achieved through adjustable components that can be repositioned to create different movement patterns, allowing one joint structure to replace what would traditionally require multiple specialized joints
2Adaptability or versatility
If a configurable universal joint with multiple axes and 360° motion is implemented, then the adaptability and cleaning versatility are improved, but the device complexity increases
Solution Approach 1:
The joint is divided into separable components including a first portion attached to the handle, a second portion attached to the mop head, and adjustable elements that can be independently repositioned. This segmentation allows each component to be optimized for specific functions while enabling easy reconfiguration by adjusting individual elements rather than redesigning the entire joint assembly
Solution Approach 2:
The joint incorporates adjustable elements that can be repositioned to dynamically change the movement characteristics. These adjustable components allow the user to modify the joint's degrees of freedom and rotation limits based on the cleaning task, transforming a static complex structure into a dynamically adaptable system
3Ease of operation
If adjustable friction engagement mechanisms are added to control pivoting, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The friction engagement mechanism uses the natural friction between contact surfaces to provide pivoting control and locking functionality. By designing surfaces with appropriate friction characteristics, the joint achieves self-regulating pivoting control where the friction itself provides the necessary resistance and locking force without requiring additional active control systems or complex fastening mechanisms
