Lateral Floor Wiper Layout for Complete Drying During Steering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Floor washing-drying machines often leave a region of the washing track undried during steering maneuvers, necessitating additional cleaning passes, increasing energy consumption, washing liquid use, and time.
Innovation Solution
The machine incorporates a pair of lateral floor wipers with three elastically flexible drying blades arranged parallel and spaced, which perform sequential drying actions – rough, fine, and finishing – to ensure complete drying, even during steering, by extending between the brushes and rear wiper, and are positioned to cover the entire wet area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the machine performs steering maneuvers, then the machine can navigate around obstacles and access different areas, but a region of the washing track remains undried requiring additional cleaning passes
Solution Approach 1:
The drying assembly is segmented into a rear floor wiper and two lateral floor wipers positioned on opposite sides of the framework. Each wiper has specific drying blades that work in sequence to cover different zones of the washing track, ensuring complete drying coverage even during steering maneuvers.
Solution Approach 2:
The drying coverage is extended from a single rear position to a three-dimensional arrangement by adding lateral wipers that extend along the longitudinal extension of the framework. This multi-level arrangement ensures that the entire wet area is covered during both straight-line and steering operations.
2Reliability
If additional cleaning passes are performed to dry undried regions, then complete drying is achieved, but energy consumption and washing liquid use increase
Solution Approach 1:
The drying blades are arranged to perform continuous sequential drying actions - rough drying, fine drying, and finishing drying - as the machine moves forward. This continuous multi-stage drying process ensures complete drying in a single pass, eliminating the need for additional cleaning passes and reducing energy consumption.
3Reliability
If additional cleaning passes are performed to dry undried regions, then complete drying is achieved, but time necessary for completion of work increases
Solution Approach 1:
The lateral floor wipers are positioned in advance along the longitudinal extension of the framework to preemptively cover areas that would otherwise remain undried during steering. The sequential arrangement of drying blades performs preliminary rough drying, followed by fine drying and finishing drying, ensuring complete drying is achieved during the initial single pass without requiring additional time for re-passes.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures complete and optimum drying of the floor during machine passage, including steering actions, reducing the need for additional cleaning passes and associated costs.
Implementation Method 1
a suction device, which comprises a suction inlet and is connected to a tank for recovering the dirty liquid, so as to allow to collect and suck the dirty liquid
Implementation Method 2
three elastically flexible drying blades arranged parallel and spaced, which perform sequential drying actions

AI summary
A floor washing-drying machine includes a framework, which can move on the floor and supports, in a lower region, a floor washing assembly having at least one rotating brush and at least one nozzle for dispensing a washing liquid. A floor drying assembly is arranged at the rear of the washing assembly, which includes a rear floor wiper, which extends substantially transversely to the advancement direction of the machine, and a suction device which is connected to a tank for recovering the dirty liquid. The machine further includes at least one pair of lateral floor wipers, which are arranged on mutually opposite sides with respect to the vertical central plane of the framework and extend substantially along at least one portion of the longitudinal extension of the framework; each one of the lateral floor wipers includes respectively at least three vertical drying blades.
