Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices face challenges in accurately determining the moisture of the cleaning medium, which affects cleaning performance and user comfort, and require manual user intervention to adapt to floor surface conditions, leading to suboptimal cleaning results and increased wear.
Innovation Solution
Incorporating a vibration sensor in the cleaning device to detect changes in vibration strength, which correlates with moisture levels, and a controller to evaluate these changes, allowing for automatic adjustment of moisture and surface adaptation through a cleaning agent dosing unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors are arranged in the dirt area to determine moisture, then moisture detection is possible, but the sensors are exposed to dirt and cleaning agent during use
Solution Approach 1:
The patent uses the cleaning medium carrier and housing as intermediary structures to transmit vibration signals from the cleaning medium to the vibration sensor. The sensor is placed in the housing rather than directly in the dirt area, yet still detects vibrations through the cleaning medium carrier, which acts as a mediator transmitting the mechanical vibrations without exposing the sensor to direct contact with dirt and cleaning agent.
2Ease of operation
If the cleaning device is operated manually with floor map determination, then user can adjust moisture settings, but optimal cleaning is not achieved and requires great user effort
Solution Approach 1:
The cleaning device automatically determines the optimal moisture setting by detecting vibrations through the cleaning medium and processing these signals through the controller. The system self-adjusts without requiring user input or manual floor mapping, eliminating the need for users to manually determine optimal settings while achieving optimal cleaning performance automatically.
Solution Approach 2:
The system continuously monitors vibrations from the cleaning medium through the vibration sensor and uses this feedback to automatically adjust moisture levels. The controller processes the vibration signals and adjusts the cleaning device operation in real-time based on the detected vibration patterns, creating a closed-loop control system that optimizes cleaning without user intervention.
3Productivity
If cleaning medium is set into oscillating movement to improve cleaning result, then cleaning performance increases, but vibrations are transmitted to user and cause wear and tear
Solution Approach 1:
The vibration sensor detects the oscillation vibrations from the cleaning medium and feeds this information back to the controller. The controller processes these vibration signals and can adjust the oscillation parameters or moisture levels to optimize cleaning performance while minimizing harmful vibrations transmitted to the user and device components.
