Cleaning Solution Reservoir Sensor for Expiration Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ineffective cleaning practices due to expired or contaminated cleaning solutions can lead to pathogen transmission and infections, particularly in environments with high employee turnover where training new employees on cleaning protocols is challenging.
Innovation Solution
A system that monitors chemical usage and expiration by detecting user interaction with a cleaning solution reservoir using sensors like accelerometers, gyroscopes, and pressure sensors, adjusting the expiration time based on detected contamination and providing alerts for solution replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cleaning solution is used for extended periods to reduce replacement frequency, then productivity improves, but cleaning efficacy deteriorates due to chemical degradation and contamination
Solution Approach 1:
The system performs preliminary detection of cleaning solution status (contamination levels, chemical concentration) and predicts expiration before actual degradation occurs. This allows proactive replacement scheduling that maintains cleaning efficacy while optimizing usage duration.
Solution Approach 2:
The system continuously monitors cleaning solution conditions using sensors and provides feedback on solution status. This feedback loop enables dynamic adjustment of replacement timing, extending usage when solution remains effective while ensuring timely replacement when degradation begins, thus resolving the contradiction between extended usage and maintained efficacy.
2Reliability
If cleaning solution is replaced frequently to ensure efficacy, then cleaning reliability improves, but productivity deteriorates due to increased replacement operations
Solution Approach 1:
The system predicts cleaning solution expiration and degradation trends in advance, allowing scheduling of replacements at optimal moments. This prevents both premature replacement (wasting productivity) and delayed replacement (compromising efficacy), achieving the balance between reliability and productivity.
Solution Approach 2:
Continuous monitoring provides real-time feedback on solution status, enabling replacement decisions based on actual condition rather than fixed schedules. This feedback mechanism ensures replacements occur only when necessary, maintaining efficacy while minimizing productivity loss from replacement operations.
3Reliability
If sensors and monitoring systems are added to track cleaning solution status, then cleaning reliability improves, but device complexity increases
Solution Approach 1:
The monitoring system uses multi-functional sensors that detect multiple parameters (contamination, concentration, temperature) simultaneously. This universal approach achieves comprehensive reliability tracking without proportionally increasing system complexity, as single sensors perform multiple detection functions.
Solution Approach 2:
The system automatically monitors, analyzes, and reports cleaning solution status without requiring manual intervention. The self-service nature of the monitoring reduces operational complexity despite adding technical components, as the system manages its own surveillance and notification functions autonomously.
4Device complexity
If manual tracking of cleaning solution expiration is used, then device complexity remains low, but reliability deteriorates due to human error and compliance issues
Solution Approach 1:
The system provides automatic feedback through alerts and notifications when cleaning solution approaches expiration or contamination thresholds. This automated feedback eliminates reliance on human memory and manual tracking, ensuring consistent compliance with cleaning protocols while keeping the overall system relatively simple through straightforward alert mechanisms.
Solution Approach 2:
The monitoring system performs self-tracking and self-reporting of cleaning solution status, removing the burden of manual tracking from human operators. This self-service capability maintains high reliability for compliance tracking while keeping device complexity low by using simple sensors and notification systems rather than complex management interfaces.

Implementation Method 1
The sensor may be an accelerometer that generates signal data indicative of movement of the cleaning chemical in the reservoir in response to a user inserting an object into the reservoir
Implementation Method 2
The sensor may be a pressure sensor that generates signal data indicative of a pressure change of the cleaning chemical in the reservoir in response to a user inserting an object into the reservoir
Implementation Method 3
The reservoir may have an accelerometer, a gyroscope, and/or a pressure sensor that detects an object being placed in the reservoir

AI summary
A system may monitor usage of a cleaning chemical and indicate when the chemical has expired and needs to be replaced. In some examples, the system includes a reservoir containing the chemical and a sensor associated with the reservoir that can detect user interaction with the chemical in the reservoir. The system may track an amount of time until the chemical in the reservoir is deemed to have expired and provide a user alert indicating expiration of the chemical. The system can control the amount of time remaining until the chemical is deemed to have expired based on the detected addition of the object to the reservoir.
