Squeegee device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing squeegee devices for floor cleaning devices, such as scrubber dryers, are difficult to attach and detach, hindering maintenance and replacement of squeegees.
Innovation Solution
A squeegee device with a holder and movable member featuring a manipulatable part and engaging part, facilitated by biasing members, allows easy attachment and detachment by manual manipulation, ensuring secure and user-friendly mounting and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a fixed mounting structure is used for squeegees, then structural stability is improved, but ease of attachment and detachment deteriorates
Solution Approach 1:
The patent applies the dynamics principle by introducing a movable member that can shift between engaged and disengaged positions. The movable member includes an engaging part that can move relative to the holder body, allowing the squeegee to be securely mounted when engaged and easily detached when disengaged. This dynamic mechanism resolves the contradiction by making the mounting structure adaptable - stable during operation but easily modifiable for maintenance.
2Device complexity
If a simple holder structure is used, then device complexity is reduced, but reliability of secure mounting deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the mounting structure into distinct functional components: a holder body, a movable member with engaging parts, and engagement protrusions. This segmentation allows each component to perform its specific function - the holder body provides structural support, the movable member enables attachment/detachment, and the engagement protrusions ensure secure mounting. The segmented design achieves reliable mounting without excessive overall complexity.
3Ease of operation
If manual manipulation is required for attachment, then ease of operation is improved, but productivity deteriorates due to time consumption
Solution Approach 1:
The patent applies self-service through the movable member's design, which automatically shifts between engaged and disengaged positions based on the squeegee's insertion or removal. When the squeegee is inserted, the engaging part automatically engages with the protrusion; when the squeegee is removed, the engaging part automatically disengages. This self-service mechanism reduces the time and effort required for maintenance while maintaining ease of manual operation.
