Release Lever Mechanism for Interchangeable Cleaning Head Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning devices with permanently fixed cleaning elements are inefficient for versatile cleaning tasks, require complex cleaning procedures, and are unsustainable due to the inability to separate and clean the element separately, while interchangeable devices lack rigidity, ease of use, and durability in their attachment mechanisms.
Innovation Solution
A cleaning device with a release lever mechanism that allows for quick attachment and detachment of interchangeable cleaning elements, featuring a pivotable lever within the cleaning element receiver to apply an ejecting force, reducing deformation and wear, and enabling versatile cleaning operations without direct contact with soiled elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a permanently fixed cleaning element is used, then manufacturing cost is reduced, but versatility and sustainability are worsened
Solution Approach 1:
The cleaning device is divided into separable components: a reusable rod assembly and replaceable cleaning elements. The cleaning element can be detached from the rod through the release mechanism, allowing the rod to be used with multiple different cleaning elements for various cleaning tasks.
Solution Approach 2:
The attachment mechanism transitions from a permanent fixed state to a dynamic removable state. The release lever enables the cleaning element to be easily detached and reattached, providing adaptability while maintaining structural integrity during use.
2Device complexity
If a permanently fixed cleaning element is used, then device structure is simplified, but cleaning procedure complexity increases
Solution Approach 1:
By separating the cleaning element from the rod assembly, the soiled element can be removed and cleaned separately (e.g., in a wringer or washing machine) without disassembling the entire device, simplifying the cleaning procedure.
Solution Approach 2:
The cleaning element can be extracted from the rod assembly for separate cleaning or replacement, eliminating the need to clean or handle the entire device when only the element requires maintenance.
3Adaptability or versatility
If conventional attachment mechanisms are used for interchangeable elements, then versatility is improved, but rigidity and durability are worsened
Solution Approach 1:
The release mechanism incorporates a cam-shaped lever with a curved engagement surface that interacts with a corresponding cam follower on the cleaning element. This curved geometry provides mechanical advantage for secure attachment while enabling easy release through lever rotation.
Solution Approach 2:
The attachment mechanism uses a dynamic cam-based system that transitions between locked and released states. The cam profile ensures strong engagement during cleaning operations while allowing controlled release when the lever is actuated.
4Ease of operation
If a release mechanism is added for element removal, then ease of use is improved, but device complexity increases
Solution Approach 1:
The release mechanism is implemented as a separate, modular lever assembly that can be integrated into the rod structure without complicating the overall device. The lever operates independently with a simple rotational motion to engage or disengage the cleaning element.
Solution Approach 2:
The cam-shaped lever acts as an intermediary between the user's manual input and the cleaning element attachment/detachment. The cam geometry translates simple lever rotation into the necessary forces for secure engagement or easy release.
