Squeegee Assembly Quick-Release Coupling for Easier Blade Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing squeegee assemblies for floor cleaning machines are cumbersome to maintain due to the difficulty in connecting and replacing squeegee blades, as they require perpendicular connectors which complicate the process.
Innovation Solution
A squeegee assembly with a frame and a biased member that engages a recess on a lifting member, allowing for easy attachment and detachment with a predetermined force, and a fork-like configuration for secure coupling, simplifying the process of connecting and replacing squeegee blades.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If perpendicular connectors are used to connect squeegee blades to the squeegee assembly, then the connection is secure, but the process of changing squeegee blades becomes cumbersome and complex
Solution Approach 1:
The squeegee blade is divided into a modular design where the blade element can be independently replaced. The lifting member with fork-like configuration allows the blade to be segmented into replaceable portions, simplifying the replacement process while maintaining secure connection through the biased member engagement system.
Solution Approach 2:
The connection system transitions from a static perpendicular connector to a dynamic biased member system that automatically engages and disengages. The biased member provides continuous engagement force during operation but allows easy release when force is applied, enabling secure connection during use while facilitating simple replacement.
2Stability of the object's composition
If multiple connectors are used to attach squeegee blades, then the attachment is stable, but the device complexity increases
Solution Approach 1:
Multiple connection functions are merged into a single integrated biased member system. The biased member combines the functions of connection, stabilization, and easy release into one component, eliminating the need for multiple separate connectors while maintaining attachment stability through its biased engagement with the lifting member.
Solution Approach 2:
The biased member serves multiple functions simultaneously: it provides secure engagement during operation, enables easy release when needed, and simplifies the overall connection mechanism. This multi-functional component replaces what would traditionally require multiple specialized connectors, reducing device complexity while maintaining stability.
