Lavatory Maintenance Management System Using Sensor-Based Priority Calculation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for managing and maintaining lavatory equipment in facilities require significant labor and resources, as they rely on manual patrols and cleaning by multiple personnel, leading to inefficiencies and increased costs.
Innovation Solution
A management system that includes an information acquirer, a work necessity determination unit, a priority calculator, and an output unit to assess the need for maintenance, calculate priorities, and allocate tasks efficiently, allowing personnel to focus on equipment that requires attention based on usage and sensor data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual patrols and cleaning by multiple personnel are used to maintain lavatory equipment, then the lavatory can be kept clean, but the labor cost and time consumption increase significantly
Solution Approach 1:
The lavatory equipment performs self-diagnosis through integrated sensors that automatically detect its own operational status, cleanliness level, and maintenance needs without requiring manual inspection by personnel
Solution Approach 2:
The system continuously monitors lavatory equipment status through sensors and provides real-time feedback to the management apparatus, enabling automatic adjustment of maintenance schedules based on actual equipment conditions rather than fixed routines
2Reliability
If a large number of personnel are deployed to clean all lavatories several times a day, then all lavatories can be maintained, but the cost and time resources are significantly increased
Solution Approach 1:
The system performs preliminary detection of maintenance needs through sensors before actual cleaning is required, allowing maintenance activities to be scheduled in advance based on predicted requirements rather than reactive responses
Solution Approach 2:
The maintenance schedule is dynamically adjusted based on real-time equipment status, usage patterns, and predicted maintenance needs, replacing fixed routine cleaning with flexible, demand-driven maintenance timing
3Ease of manufacture
If fixed routine cleaning schedules are implemented for all lavatories, then maintenance can be performed systematically, but unnecessary work is performed on equipment that does not require attention
Solution Approach 1:
The system applies different maintenance strategies to different lavatory equipment based on their individual characteristics, usage patterns, and actual condition, rather than applying uniform routine cleaning to all equipment
Solution Approach 2:
The maintenance frequency and type are adjusted as parameters based on changing equipment conditions, usage rates, and sensor data, allowing the system to adapt maintenance intensity to actual needs
Data Source
AI summary
In a management apparatus, an information acquirer acquires information from at least one of lavatory equipment and a sensor installed in a lavatory space. A work necessity determination unit determines, based on the acquired information, the lavatory equipment that requires work including cleaning and at least one of replenishment of a consumable and removal of an abnormality. A priority calculator calculates a priority of the work for the lavatory equipment determined to require the work based on the acquired information. An output unit outputs the calculated priority.
