Method for cleaning a floor surface and floor cleaning device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor cleaning technologies lack a straightforward method to verify the effectiveness of cleaning results in real-time, often requiring pre-mapping of dirtiness levels and subsequent position-dependent cleaning, which can prolong the cleaning process and reduce efficiency.
Innovation Solution
A method and device that utilize optical recording units to capture before-and-after images of floor sections during cleaning, allowing for immediate comparison to assess cleaning efficacy and enable rapid identification of areas needing re-cleaning, thus eliminating the need for pre-mapping and reducing positional inaccuracies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pre-mapping of dirtiness levels is performed before cleaning, then cleaning effectiveness can be verified, but cleaning time increases and efficiency decreases
Solution Approach 1:
The patent applies preliminary action by capturing the 'before' state of the floor surface with an optical recording unit before cleaning occurs. This allows the system to have reference data ready for immediate comparison after cleaning, enabling verification without requiring time-consuming pre-mapping of dirtiness levels across the entire area.
Solution Approach 2:
The patent implements feedback by comparing the 'before' recording with an 'after' recording captured by the optical recording unit. This comparison provides immediate feedback on cleaning effectiveness, allowing verification of cleaning results without extending the overall cleaning time significantly.
2Manufacturing precision
If position-dependent cleaning is performed based on stored dirtiness data, then cleaning coverage is improved, but positional inaccuracies increase
Solution Approach 1:
The patent uses optical recording units to create visual copies (images) of the floor surface before and after cleaning. These visual records serve as direct evidence of cleaning effectiveness at specific locations, eliminating the need for complex position-dependent data storage and reducing reliance on precise positioning systems.
Solution Approach 2:
The patent replaces mechanical positioning and dirtiness mapping systems with an optical recording and image comparison system. Instead of using sensors to map dirtiness levels position-dependently, the system captures visual records that can be directly compared to verify cleaning results, substituting optical methods for mechanical measurement approaches.
3Reliability
If intensive cleaning is performed for heavy dirt areas, then cleaning effectiveness improves, but cleaning process complexity increases
Solution Approach 1:
The patent enables the cleaning system to perform intensive cleaning only where needed by comparing before and after optical recordings. If the comparison shows insufficient cleaning in a particular area, the system can apply additional cleaning passes locally rather than requiring complex pre-planning of intensive cleaning zones, simplifying the overall process control.
