Robot Floor Cleaner Moisture Warning for Spill Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current autonomous floor cleaners, particularly wet models, are prone to improper use by consumers, leading to potential liquid spills due to incorrect orientation or handling, which can result in operational issues and safety hazards.
Innovation Solution
Incorporating a moisture sensor and a warning system within the autonomous floor cleaner that detects moisture inside the housing and issues an audible warning to alert the user of potential spills or improper use, ensuring safe operation and preventing liquid spills.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a moisture sensor and warning system are added to detect moisture inside the housing, then user safety and prevention of improper use are improved, but device complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where a moisture sensor continuously monitors the interior environment of the housing and provides real-time data to a control system. When moisture is detected, the system generates an audible warning signal to alert the user. This closed-loop feedback approach enables the device to automatically respond to improper conditions, thereby improving user safety and preventing damage without requiring complex manual monitoring systems.
Solution Approach 2:
The patent introduces an intermediary warning system that acts as a mediator between the moisture sensor detection and the user. Instead of directly addressing the user with complex technical data, the system uses a simple audible warning signal as an intermediary communication method. This intermediary approach simplifies the user interface while maintaining effective safety monitoring, resolving the contradiction between reliability improvement and device complexity.
2Adaptability or versatility
If liquid is held in on-board tanks for wet cleaning, then cleaning versatility is improved, but risk of spills and harmful factors increases
Solution Approach 1:
The patent applies preliminary action by detecting moisture conditions before actual spills or harmful effects occur. The moisture sensor monitors the interior environment proactively, and the warning system alerts users to correct improper orientation or handling before liquid can escape from the tanks. This preventive approach allows the device to maintain cleaning versatility while mitigating spill risks through early detection and user alerting.
Solution Approach 2:
The patent converts the potentially harmful presence of liquid in tanks into a beneficial safety feature. By using the moisture associated with liquid presence as a detectable signal, the system transforms what could be a hazard (liquid that might spill) into a useful indicator for monitoring device orientation and proper operation. The moisture detection capability, which could indicate a problem, is instead used as a preventive safety mechanism that alerts users to correct handling before spills occur.
Applied Scientific Principles
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 warning system effectively discourages improper use and reduces the risk of spills by alerting the user to correct the orientation or dry the device, enhancing user safety and preventing operational failures.
Implementation Method 1
a moisture sensor configured to detect moisture at a location inside the housing and outside the tank
