Control apparatus for self-cleaning of floor scrubber, and floor scrubber
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor scrubbers face inconvenience and inefficiency in self-cleaning operations, particularly when placed against a wall, and manual activation often results in wet hands and compromised functionality.
Innovation Solution
A control device with an excitation portion in the base portion and a sensing portion in the main machine portion that triggers self-cleaning based on a sensing signal, allowing activation via foot operation, eliminating the need for manual button pressing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a manual self-cleaning button is provided on the handle, then the floor scrubber can perform self-cleaning function, but the operation becomes inconvenient when placed against a wall and water may flow into the interior when pressed with wet hands
Solution Approach 1:
The patent replaces the mechanical button-pressing system with a foot-operated pedal system. The pedal (512) is positioned at the rear end of the base portion, allowing users to activate self-cleaning by stepping on it with their foot rather than pressing a button with wet hands. This mechanical substitution eliminates the problem of water infiltration while maintaining the self-cleaning function.
Solution Approach 2:
The patent introduces a pedal as an intermediary between the user and the self-cleaning activation mechanism. Instead of direct hand-to-button contact, the foot acts as an intermediary to trigger the self-cleaning mode through the pedal, which then activates the control system. This intermediary mechanism prevents water from reaching the control interior.
2Ease of operation
If the self-cleaning button is placed on the handle for easy access, then manual operation is simplified, but operation becomes very inconvenient when the floor scrubber is placed against a corner of wall
Solution Approach 1:
The patent moves the activation mechanism from the vertical dimension (handle at top) to the horizontal dimension (pedal at rear end of base). By positioning the pedal at the rear end of the base portion, it becomes accessible from the side even when the scrubber is placed against a wall, providing multi-directional accessibility that adapts to different placement positions.
Solution Approach 2:
The pedal design provides universal accessibility from multiple positions and angles. Whether the scrubber is placed against a wall, in a corner, or in an open space, the pedal at the rear end remains accessible to the user's foot, making the self-cleaning function adaptable to various placement scenarios.
