Release Lever Mechanism for Quick-Change Cleaning Head Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning devices with permanently fixed cleaning elements are not suitable for versatile cleaning tasks, as they require a specific procedure for cleaning and are inefficient in terms of sustainability, with limited means for securing cleaning elements that lack rigidity, ease of use, and durability.
Innovation Solution
A cleaning device with a release lever that allows quick attachment and detachment of cleaning elements, featuring a handle at one end and an ejecting surface at the other, configured to rotate and apply an ejecting force against the cleaning element frame within the cleaning element receiver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a cleaning element is permanently fixed to the rod, then the cleaning device is cheaper to manufacture, but the cleaning device cannot be used for versatile cleaning tasks and requires replacement of the entire device instead of just the cleaning element
Solution Approach 1:
The cleaning device is divided into separate components: a reusable rod/handle assembly and replaceable cleaning elements. The cleaning element can be detached and replaced independently from the rod, allowing users to swap cleaning elements for different tasks without replacing the entire device. This segmentation enables both cost-effective manufacturing of the main body and flexible adaptability through element replacement.
Solution Approach 2:
The cleaning device transitions from a static, permanently fixed design to a dynamic, interchangeable system. The release lever mechanism enables the cleaning element to be easily attached and detached, creating a flexible system that can adapt to different cleaning needs. This dynamic capability allows the device to evolve and serve multiple purposes throughout its lifecycle.
2Device complexity
If conventional means are used to secure the cleaning element to the rod, then the device structure is simpler, but the means lack rigidity, ease of use, and durability
Solution Approach 1:
A release lever mechanism serves as an intermediary component between the cleaning element and the rod. This lever provides a mechanical advantage system that enables easy attachment and detachment while maintaining a secure, rigid connection during use. The lever acts as a mediator that transforms simple user input into reliable securing or releasing action, solving both the simplicity and reliability requirements.
Solution Approach 2:
The release lever mechanism is designed to be operated by the user without requiring additional tools or complex procedures. The user can easily engage and disengage the cleaning element through intuitive manual operation of the lever, making the securing means self-servicing and user-friendly while maintaining durability through repeated use.
3Device complexity
If the cleaning element is permanently attached to the rod, then there are fewer components, but the cleaning element and remaining components cannot be cleaned separately
Solution Approach 1:
The cleaning system is segmented into removable cleaning elements and a permanent rod assembly. This segmentation allows the cleaning element to be detached for separate cleaning or replacement, while the rod and other components can be cleaned independently. The modular design enables targeted cleaning of soiled elements without requiring disassembly or cleaning of the entire device.
4Adaptability or versatility
If replaceable cleaning elements are used, then versatility is improved, but the means for securing elements are limited in terms of rigidity, ease of use, and time required to switch elements
Solution Approach 1:
The release lever acts as a mechanical intermediary that accelerates the element replacement process. By providing leverage and mechanical advantage, the lever reduces the time and effort required to attach and detach cleaning elements compared to direct manual insertion or removal. This intermediary mechanism enables quick element switching while maintaining secure attachment during cleaning operations.
