Solution Overview

Problem

Existing automatic floor cleaning systems for public sanitary facilities are limited by the need for a wall-mounted cleaning element, which restricts the placement of doors and affects the interior layout of the space.

Innovation Solution

The system integrates the cleaning element into the floor itself, allowing it to be received in the floor in a rest position, thus enabling the placement of doors in other walls and optimizing the layout of public sanitary facilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the cleaning element is mounted in the wall, then the cleaning function is achieved, but the placement of doors is restricted and interior layout is limited

Engineering Contradiction:
Improveinterior layout flexibilityVSAvoidmounting structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Instead of mounting the cleaning element in the wall as in prior art, the invention inverts the mounting location by integrating the cleaning element directly into the floor. The cleaning element is received in the floor in rest position and can move across the floor surface, thereby eliminating the restriction on wall door placement and improving interior layout flexibility.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The invention transitions the cleaning element from a vertical wall-mounted configuration to a horizontal floor-integrated configuration. This dimensional change allows the cleaning element to operate along the floor surface while leaving walls free for door placement, thus resolving the spatial conflict between cleaning functionality and architectural flexibility.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If the cleaning element is integrated into the floor, then door placement flexibility is improved, but the system complexity increases

Engineering Contradiction:
Improvedoor placement flexibilityVSAvoidfloor integration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The floor-integrated cleaning system is designed as a universal solution that can be implemented in various floor types and configurations. The cleaning element, guiding element, and drive system work together as an integrated unit that maintains universal applicability while enabling flexible door placement throughout the facility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The invention relates to a system (1) for automatically cleaning a surface of a floor, comprising a cleaning element (10). The system is arranged for moving the cleaning element relative to the floor between a rest position and a position of use, in which the cleaning element is moveable across the floor surface. The cleaning element (10) is received in the floor in the rest position. The system (1) further comprises a guiding element (20) on which the cleaning element (10) is movable. Adjacent to the guiding element (20) floorplates (100) are arranged such that gutters (102) are defined between the floorplates (100) and the guiding element (20) The invention also relates to a floor provided with the system (10) according to the invention.
