Portable Restroom Sensor Monitoring for Condition-Based Servicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable restrooms often become dirty or full sooner than expected due to inaccurate estimation of usage, leading to unsanitary conditions and undesirable images, as they are typically serviced with the same frequency regardless of actual usage, causing some to become full or dirty before others.
Innovation Solution
A portable restroom system equipped with sensors and control electronics for real-time monitoring and data gathering, connected to a central computer system that manages inventory and alerts, allowing for optimized servicing based on actual usage and conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If portable restrooms are serviced with the same frequency regardless of actual usage, then the servicing process is simple and uniform, but some restrooms become dirty or full sooner than others creating unsanitary conditions
Solution Approach 1:
The patent implements a feedback mechanism through sensors that continuously monitor restroom usage levels, waste tank fullness, and hygiene conditions. This real-time data is transmitted to a central system that adjusts servicing schedules dynamically, ensuring restrooms are serviced based on actual conditions rather than fixed schedules, thereby maintaining cleanliness while optimizing service frequency
Solution Approach 2:
The system transitions from static, uniform servicing schedules to dynamic, condition-based servicing. The centralized control system adjusts service frequency and timing based on real-time sensor data from individual restrooms, allowing high-usage restrooms to be serviced more frequently while low-usage restrooms receive service less often, optimizing both sanitation and resource allocation
2Productivity
If portable restrooms are monitored with real-time sensors and data collection, then servicing frequency can be optimized based on actual usage, but the device complexity increases
Solution Approach 1:
The patent employs multi-functional integrated sensors that simultaneously monitor multiple parameters including usage detection, waste level measurement, hygiene condition assessment, and environmental monitoring. This consolidation of functions into unified sensor units reduces the number of separate components needed while maintaining comprehensive monitoring capabilities, thereby optimizing servicing efficiency without proportionally increasing system complexity
Solution Approach 2:
The system introduces a centralized control system as an intermediary between the distributed sensors and the servicing operations. This intermediary aggregates data from multiple sensors, processes information, and generates service schedules, simplifying the overall architecture by centralizing intelligence rather than requiring complex distributed decision-making at each restroom location
3Measurement precision
If real-time data gathering and analysis is implemented, then servicing can be triggered by actual conditions rather than estimates, but the loss of time in data transmission and processing increases
Solution Approach 1:
The system performs preliminary data aggregation and analysis at the sensor level before transmission to the centralized system. Sensors pre-process and filter data locally, identifying only the most critical threshold breaches or usage patterns that require attention. This preliminary action reduces the volume of data needing transmission and processing, minimizing time loss while maintaining high measurement precision for triggering servicing operations
Data Source
AI summary
A portable restroom is provided with a suite of sensors and control electronics to monitor and report real time conditions and usage data for the portable restroom. Similar technology can be applied to service trucks, restroom trailers, and portable vacuum toilets for the portable restrooms. A central control computer can maintain databases of data and alerts for each restroom and truck. The central control computer can also track and manage inventory of consumable products for the portable restrooms. A user app can interface with the central control computer to monitor restroom status and consumable consumption, route service technicians and manage inventory of consumables, among other functions and features.
