Ratcheting Jaw Holder for Hands-Free Cleaning Implement Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional devices for retaining cleaning implements require users to physically handle soiled implements for cleaning or disposal, and are not easily adaptable for different types or sizes of cleaning tools.
Innovation Solution
A ratcheting mechanism with pivoting jaws and a release button allows for secure attachment and removal of cleaning implements without direct contact, featuring a housing with a lever and lock system that engages ratchet teeth to facilitate easy handling and adjustment for various handle types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional retaining devices are used, then the device structure is simple, but the user must physically handle soiled cleaning implements causing safety issues and the device is not easily adaptable for different cleaning tools
Solution Approach 1:
The retaining device is designed with adjustable jaws that can accommodate different sizes and types of cleaning implements (mops, brooms, brushes). The ratcheting mechanism provides universal retention functionality across various tool types, allowing one device to serve multiple cleaning purposes rather than requiring separate devices for each tool type.
Solution Approach 2:
The device incorporates a ratcheting mechanism with movable jaws that can dynamically adjust to different implement sizes. The lever system allows the jaws to open and close on demand, providing dynamic adaptability rather than a fixed structure, enabling the same device to retain various cleaning tool sizes effectively.
2Object-affected harmful factors
If traditional retaining devices are used, then the device structure is simple, but the user safety is compromised due to direct contact with soiled implements
Solution Approach 1:
The ratcheting mechanism acts as an intermediary between the user and the cleaning implement. The lever system provides a mechanical interface that allows users to open and close jaws without directly touching soiled implements, while still maintaining full control over the retention and release process. This mediator protects users from harmful contact while preserving operational ease.
Solution Approach 2:
The ratcheting mechanism is designed to be self-operating through the lever system. Once the lever is actuated to open the jaws, the mechanism automatically releases the implement without requiring additional manual manipulation or direct contact with the soiled tool, allowing the device to serve itself in the release function.
3Reliability
If a secure retention mechanism is used, then the cleaning implement is securely held, but the mechanism for attachment and removal becomes complex
Solution Approach 1:
The device replaces complex multi-component retention systems with a simplified lever-operated ratcheting mechanism. The ratchet teeth and pawl design provides secure one-way locking with minimal moving parts, while the lever provides mechanical advantage for easy operation. This substitution maintains reliable retention while reducing overall mechanism complexity compared to traditional multi-screw or clamp-based systems.
4Ease of operation
If easy release mechanism is used, then the cleaning implement can be quickly removed, but the retention security may be compromised
Solution Approach 1:
The ratcheting mechanism allows for periodic engagement and disengagement of the retention function. During normal operation, the jaws remain securely closed through the ratchet locking action. When release is needed, a brief periodic action of the lever quickly disengages the ratchet, allowing rapid implement removal. This periodic on-demand release maintains security during use while enabling easy removal 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
Enables users to efficiently attach and detach cleaning implements without touching them, providing mechanical advantage and versatility in handling different types and sizes of cleaning tools, enhancing user safety and convenience.
Implementation Method 1
the lock is biased by a spring to pivot toward the ratchet teeth of the first jaw when the release button is released
Implementation Method 2
the ratchet arm is biased by a spring to pivot away from the ratchet teeth of the first jaw when the lever is moved from the actuated position to the pre-actuated position
Implementation Method 3
The lever is connected to the ratchet arm and actuating the lever causes the ratchet arm to move into the actuated position to incrementally pivot the first jaw toward the second jaw

AI summary
An apparatus to retain an article includes a housing, a first jaw, a second opposed jaw, a pivoting ratchet arm, and a lever. The housing is adapted to receive a handle. The first jaw is adapted to pivot with respect to the housing. The pivoting ratchet arm is dimensioned to engage ratchet teeth of the first jaw when in an actuated position. The lever is connected to the ratchet arm and actuating the lever causes the ratchet arm to move into the actuated position to incrementally pivot the first jaw toward the second jaw.
