Elastic Handle Holder for Multi-Diameter Cleaning Tool Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handle holders for cleaning tools are inadequate as they fail to securely retain handles with different diameters and configurations, are prone to unexpected detachment, and do not function well with wet or irregularly shaped handles, and often have complex designs that are difficult to clean.
Innovation Solution
A single-piece handle holder device with a support element and an elastic retention element that partially surrounds the handle, featuring hooking devices and a thermo-moulded connection, allowing for secure retention of various handle sizes and configurations, and easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a handle holder uses compression on two opposite sides to retain a handle, then it provides solid retention for a precise handle diameter, but it retains handles with smaller diameter with excessive slack and fails to hold handles with larger diameter
Solution Approach 1:
The handle holder employs an elastic element that can dynamically adjust its compression force and circumference to adapt to different handle diameters. The elastic element deforms elastically under the weight of the handle and maintains continuous contact pressure, automatically adjusting to the specific diameter of each handle while providing reliable retention.
Solution Approach 2:
The invention changes the physical parameters of the retention mechanism by using an elastic element with specific elastic properties. The elastic element's ability to deform and recover allows it to maintain appropriate compression force across a range of handle diameters, transforming a fixed-parameter system into a variable-parameter system that adapts to different handles.
2Reliability
If a handle holder is made of materials that adequately hold the handle, then it provides secure retention, but it fails with regard to wet or damp handles
Solution Approach 1:
The invention converts the potentially harmful effect of moisture into a beneficial one by using an elastic element that maintains reliable friction-based retention even on wet surfaces. The elastic deformation and continuous contact pressure compensate for the reduced friction coefficient of wet surfaces, transforming the moisture condition from a liability into a manageable parameter.
3Adaptability or versatility
If a handle holder uses hinges and complex mechanisms, then it provides adjustable retention, but it has hidden and narrow parts that are difficult to reach and clean
Solution Approach 1:
The invention merges multiple functions into a single elastic element that simultaneously provides retention, adaptation to different diameters, and moisture resistance. By eliminating hinges, joints, and complex mechanisms, the design achieves full cleanability while maintaining adjustable retention through elastic deformation alone.
Solution Approach 2:
The elastic element functions as a flexible structure that can deform to accommodate different handle sizes without requiring mechanical joints or hinges. This flexible design allows complete surface access for cleaning while maintaining adaptive retention through elastic deformation.
4Device complexity
If a handle holder relies on retention using the weight of the handle or gravitational device, then it is simple in design, but it can detach due to sudden strains or upward jolts
Solution Approach 1:
The elastic element is configured to surround the handle in a curved or circumferential manner, creating continuous contact pressure around the handle circumference. This curved geometry distributes the retention force evenly and prevents detachment during sudden strains or upward jolts, while maintaining relative design simplicity.
