Mop Base Coupling Device for Contamination-Free Cloth Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mop bases require manual intervention and multiple complex operations to replace the cleaning cloth, leading to operator contamination and inefficiency, with precarious retention mechanisms that are difficult to use.
Innovation Solution
A mop base with coupling devices featuring a double lever system and enlarged end tabs, allowing for automatic release and attachment of the cloth without manual handling, using elastic devices to open and close the retention cavity, enabling single-handed operation and secure retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual intervention is used to replace the cleaning cloth, then the cloth can be replaced, but operator contamination and inefficiency occur
Solution Approach 1:
The coupling device enables automatic cloth attachment and release without manual handling. The elastic device automatically engages the cloth's enlarged end with the retention cavity, and the lever mechanism automatically releases it, allowing the system to serve itself without operator intervention and preventing contamination.
Solution Approach 2:
The coupling device acts as an intermediary mechanism between the operator and the cloth. Instead of directly handling the cloth, the operator interacts with the lever, which mediates the attachment and release processes through mechanical action, eliminating direct contact with the cleaning cloth.
2Reliability
If multiple complex operations are used to attach and release the cloth, then secure retention is achieved, but operational complexity increases
Solution Approach 1:
The coupling device is segmented into functional components: the lever for operation, the elastic device for retention force, and the retention cavity for positioning. This segmentation allows each component to perform its specific function independently, achieving secure retention through a simplified single-action operation rather than multiple complex steps.
Solution Approach 2:
The coupling device transitions between dynamic states: the lever moves between engaged and disengaged positions, the elastic device dynamically adjusts retention force, and the inlet mouth opens and closes automatically. This dynamic behavior enables secure retention during attachment while allowing easy release through a single operational movement.
3Ease of operation
If a simple retention mechanism is used, then ease of operation improves, but retention security deteriorates
Solution Approach 1:
The cloth's enlarged end features a curved or rounded geometry that complements the retention cavity's shape. This geometric design allows the enlarged end to be inserted into the cavity through a simple pushing motion while ensuring secure retention through the interlocking curved surfaces, combining ease of operation with retention security.
4Ease of operation
If the inlet mouth is always open for easy cloth insertion, then ease of operation improves, but premature release risk increases
Solution Approach 1:
The elastic device is pre-loaded to maintain the inlet mouth in a closed position before cloth insertion. When the cloth's enlarged end is introduced, it automatically triggers the lever to open the inlet mouth, allowing insertion. After insertion, the lever returns to close the inlet mouth, preventing premature release. This preliminary positioning of the elastic device enables both easy insertion and secure retention.
