Squeegee Blade Attachment Mechanism for Quick Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing squeegee devices for floor cleaning devices, such as scrubber dryers, are difficult to attach and detach from the cleaning device, necessitating improved attachment and detachment mechanisms.
Innovation Solution
A squeegee device comprising a squeegee and a holder that extends in a left-right direction, with blades mounted on a body and trapped by plates, allowing easy attachment and detachment through protrusions and recesses on the blades and plates, and a mechanism involving movable members and biasing members for secure mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional attachment mechanisms are used for squeegee blades, then the blades can be securely fixed to the floor cleaning device, but the attachment and detachment process becomes time-consuming and difficult
Solution Approach 1:
The squeegee device is divided into separable components: the holder body, the squeegee assembly, and the blade. This segmentation allows each component to be independently attached and detached, enabling quick blade replacement without disassembling the entire device. The holder body can be detached from the floor cleaning device, and the blade can be replaced on the squeegee assembly, creating multiple independent attachment points that simplify maintenance operations.
2Reliability
If simple attachment mechanisms are used for squeegee blades, then the attachment process becomes quick and easy, but the security and stability of blade fixation is reduced
Solution Approach 1:
The attachment and detachment functions are extracted as separate, dedicated mechanisms: protrusions for attachment and recesses for detachment. This extraction allows each function to be optimized independently - the protrusions provide secure mechanical interlocking for reliable fixation, while the recesses offer easy access for quick detachment. By separating these functions into distinct structural elements rather than using a complex multi-functional mechanism, the design achieves both reliability and simplicity.
3Strength
If multiple components are used for blade attachment (plates, protrusions, recesses), then the blade can be securely trapped and fixed, but the number of parts increases making assembly more complex
Solution Approach 1:
Multiple attachment functions are merged into integrated components. The holder body incorporates both protrusions and recesses as built-in features rather than separate fasteners. The squeegee assembly merges the blade mounting structure with the holder connection points. This merging reduces the total number of discrete parts while maintaining strong blade trapping through the combined action of protrusions and recesses, simplifying both manufacturing and assembly processes.

AI summary
A squeegee device (11) includes a squeegee (12) and a holder (13), which extends in a left-right direction and which holds the squeegee. The squeegee has a blade (21), a body (22) on which the blade is mounted, and a plate (23), which traps (holds, fixes, sandwiches, presses) the blade against the body.
