Cleaning device for a floor cleaning machine and floor cleaning machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor cleaning tools are difficult to fix and replace quickly on floor cleaning machines, lacking efficient mechanisms for tool immersion and secure attachment.
Innovation Solution
The cleaning tool features a tapered insertion area that widens into a larger receiving space, providing a guide for easy immersion and secure fixation, along with a support part that includes ribs and a contact element for rotational and axial fixation, enabling simple tool changes and secure attachment to the tool holder head.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional cylindrical receptacle is used for holding the tool holder head, then the structure is simple, but the tool holder head is difficult to immerse and replace quickly
Solution Approach 1:
The receptacle incorporates a tapered conical insertion area that transitions into a cylindrical holding area. This curved/tapered geometry provides a guiding function that facilitates easy immersion of the tool holder head while maintaining structural simplicity. The gradual narrowing from the insertion area to the holding area creates a self-aligning mechanism that simplifies the replacement operation.
2Ease of operation
If the receiving space has a uniform diameter throughout, then the structure is simple, but there is insufficient play for positioning the cleaning tool during immersion
Solution Approach 1:
The receptacle features a non-uniform diameter design where the insertion area has a larger diameter that gradually tapers to a smaller diameter at the holding area. This local variation in geometry provides the necessary play and positioning freedom during the immersion process, while the final holding area ensures secure fixation. The tapered transition zone allows for easy alignment and insertion without compromising replacement speed.
3Ease of manufacture
If the wall is made with a simple cylindrical shape, then manufacturing is easy, but mechanical rigidity is reduced
Solution Approach 1:
The wall is designed with a tapered conical insertion area that transitions into a cylindrical holding area. This curved/tapered geometry provides structural reinforcement while maintaining manufacturing feasibility. The varying wall thickness and angular transitions in the tapered section enhance mechanical rigidity without requiring complex multi-component construction, thus balancing strength requirements with ease of manufacture.
